A. SCHWARZ. In the year 1879 I had an opportunity of becoming acquainted with the insect fauna of the vicinity of Columbus, Texas, on the lower Colorado River. The fauna at this point, both of the densely wooded river valley as well as of the adjoining more elevated prairies, is but little modified from the austroriparian fauna of Louisiana. West of the Guadalupe River a change in the character of flora and fauna gradually takes place, owing to the greatly diminished amount of rainfall. This is southwestern Texas, or more properly the low-lands of western Texas, and south of the Nueces River the characteristic features of this region attain their highest development. With the insect fauna of this region I became tolerably well acquainted the past year, during the investigation of the Mexican cotton-boll weevil \An- thonomus grandis}, carried on by the U. S. Department of Ag riculture. It differs essentially from that of Columbus, Tex., but also, though in a lesser degree, from the fauna of the higher plateaus of Texas north and northwest of San Antonio. Still, southwestern Texas belongs, at least as far as the insects are con cerned, to the lower Sonoran fauna, of which it forms a marked Z ENTOMOLOGICAL SOCIETY subdivision,* but with marked affinities to the austroriparian region. The valley of the Rio Grande nowhere forms a natural divid ing line, and the flora and fauna of southwestern Texas extend into the State of Tamaulipas how far south, I am unable to state. The explorers of the Mexican fauna have entirely neglected this region, and only a few representatives thereof are recorded in the Biologia Centrali-Americana. That a number of genera and species of animals belonging to the neotropical region extend northward along the tierra caliente of eastern Mexico and cross the Rio Grande into Texas has long since been recognized, but since nothing definite regarding the exact extent of the region where this tropical fauna is to be found north of the Rio Grande seems to be known, at least so far as the insects are concerned, I venture to place on record a few ob servations made by myself during a very short visit to the lower Rio Grande in June, 1895. Collections made at Laredo, San Diego, Corpus Christi, and in the lower Nueces river valley prove that, with few exceptions, no tropical forms occur in that section, and the trip on the stage from Alice to Brownsville shows that the character of the coun try does not change southward until the black alluvial soil of the delta of the Rio Grande is reached. Here, within the bends of the river, as well as along: the various backwaters and old river O arms (resacas) which dissect the delta, isolated areas or strips of larger or smaller extent are covered with a dense forest having thick undergrowth of varied shrubbery and a rich vegetation of lower plants, the like of which is not seen at any other place in southwestern Texas. These forest jungles (in Florida they would be called hammocks) are the home of the semi-tropical insect fauna of Texas, which, so far as known to me, has, previous to the year 1895, never been investigated by any entomologist, since even many of the most abundant species are either entirely new or not yet recorded from the United States. If, confining myself to Coleoptera found by Prof. Townsend or myself near Browns ville, I mention the genera Agra, Dasydactylus, Physorhinus, Achryson, Gnaphalodes, Amphionycha, Megascelis, Plectrotreta, Brachycoryne, Listronychus, Polypria (quite a number of others are not yet determined, or undescribed), no one can deny the ex istence of a semi-tropical insect fauna along the north bank of the lower Rio Grande. The number of species composing this fauna is very large ; in Coleoptera alone I estimate that, after proper ex- * Prof. E. D. Cope, in his paper " On the Zoological position of Texas " (Bull. 17, U.

The following paper was then read by the Secretary : ON THE AFFINITIES OF NEOLARRA. By CARL F. BAKER, Fort Collins, Colo. In Bulletin I of the Colorado Biological Association, Mr. Ashmead erected the genus Neolarra on a unique male hymen- opterous insect collected by Mr. Cockerell at West Cliff, Custer Co., Colo., and named the species pruinosa. Following the description he says: "This remarkable insect exhibits strong Larrid affinities in shape, general appearance, and in the par tially aborted ocelli, and I was inclined at first to place it in the Larridcc^ but the distinctly produced labrum, only noticed when describing, induced me to place it finally with the Bembecidce ; and it will probably form a distinct tribe in this group, although in its wing characters it is entirely different from any Hymenop- tera known to me." Later, Mr. Fox borrowed the unique type and in Entomological News, IV, p. 292, published a figure of the wing and a fuller generic description, rightly calling the type a male instead of a female, as described by Mr. Ashmead. Re garding its affinities, Mr. Fox says: " I quite agree with Mr. Ashmead in stating that it will probably form a distinct tribe of the Bembecidce (so-called), and go further and believe it to represent a distinct group intermediate between the so-called jBembecidce and Larridcz. As several authors have demon strated that the Larridce and Bcmbccida are not entitled to family distinction, representing nothing but groups of the Sphec- idce, the discovery of Neolarra tends to make the assertion stronger. While its affinities to the Bembccida are shown in the strongly protruding labrum and form of the mandibles, yet its relation to the Larrites is evident in the wings, which are not very dissimilar to the genus Dinetus." During the past summer I collected specimens (male and fe male) of this species at Fort Collins, on the flowers of Eriogo- num microthecum var. effusum. A little later I took a single OF WASHINGTON. 21 specimen of a new species which seemed in many respects very near Neolarra, but which differed in having but one submar ginal cell and two discoidals. I at once communicated the news of these two captures to Prof. Cockerell. In a reply he advised me to compare Neolarra and Phileremus! Not having the material or time to make the comparison, I had dropped the subject until Prof. Cockerel] sent me specimens of his new Phi leremus verbesince, which was then undescribed. I was sur prised to find verbesince strictly congeneric with Neolarra pruinosa, and was greatly astonished to see that both were un mistakably BEES. They have the greatly produced mouth-parts usual to nearly related bees, and the hairs clothing the body are compound and plumose. I immediately wrote Prof. Cockerell again, but before hearing from him, received the copy of Psyche in which he describes Phileremus verbesince, and the form mentioned above with one submarginal cell and two discoidals which he had also found at Las Cruces as a new genus and species, Phileremulus vigilans. He also describes an addi tional species of the same genus as Phileremulus nana. In his reply Prof. Cockerell states that he had communicated to Mr. Fox his suspicions regarding the affinities of Neolarra and Phileremus and had received the assurance that Neolarra was not a bee. But, strange to say, Phileremulus which in general appearance is the exact counterpart of Neolarra Mr. Fox ad mits is a bee, and a new genus, and stranger still, advises that verbesince, which is straight Neolarra, be placed in Philere mulus as a section or subgenus. Considering the history of Neolarra, such a result (viz : Neolarra a bee) seemed so entirely improbable, that I con cluded there must have been an error in the determination of my specimens. At this juncture, however, Mr. Ashmead most kindly loaned me the type. It is a very poor specimen, the body almost entirely denuded, the wings and legs on one side gone, those on the other side in poor condition, and the mouth-parts wholly retracted. It enabled me, however, to definitely deter mine my specimens as Neolarra pruinosa. It is scarcely to be wondered that Messrs. Fox and Ashmead found Neolarra a most difficult form to place among the Fossores. But Neolarra is not Phileremus, and the name will have to be retained, though a most unfortunate misnomer. These allied genera may be distinguished as follows : a. Anterior wings with one submarginal cell and two discoidals; margi- nal'cell scarcely exceeding stigma Phileremulus. aa. Anterior wings with two submarginal cells and three discoidals. b. Second submarginal cell much higher than broad and receiv- 22 ENTOMOLOGICAL SOCIETY ing the second recurrent nervure, the first recurrent joining the first transverse cubital nerve or entering the first sub- marginal cell at the extreme apex; marginal cell scarcely exceeding stigma Neolarra. bb. Second submarginal cell much broader than high, and re ceiving both the recurrent nervures ; marginal cell greatly exceeding stigma Phileremus In Phileremulus the first recurrent nervure plainly enters the submarginal cell before its apex. As the drawing of the wing of Neolarra presented by Mr. Fox in his article (1. c.) is incor rect in several respects, I give herewith drawings of the wings of both Neolarra and Phileremulus. The veins above the second submarginal cell in Neolarra are usually not so much thickened as in the specimen from which the drawing was made. FIG. i. A, Forewing of Neolarra pruinosa ; B, C, Fore and hind wings of Phileremulus vigilans (original). In Neolarra the tibial spurs are not i-i-i as stated by both Ashmead and Fox, but 1-1-2, the same as in Phileremulus. In the type of N. pruinosa the remaining posterior leg is so imbedded in glue that a careful examination of the tibial spurs would be impossible. The extruded mouth-parts in Neolarra are nearly as long as the head ; the labial palpi are 4-joiiited, the first joint about as long as the rest combined ; the maxillary palpi appear to be 5 -jointed, though this may be incorrect. The OF WASHINGTON. 23 small size of the posterior ocelli in A 7 ", pruinosa is a character of specific value only, as in the very nearly related A", verbesince they are all large and of equal size. In Philcremulus they are also of the same size. Of the clypeus in Neolarra, which Mr. Ash- mead describes as " not separated," Mr. Fox says u seems to be divided into three lobes, the middle one being by far the largest, most prominent, and extends up between the insertion of the antennae." It is separated, however, its form being very strongly outlined in undenuded specimens by the manner of growth of the pubescence of the face. By the use of a high-power lens the sutures can be distinguished in the denuded specimen. This sclerite is subtrapezoidal in form, wider than long, the base truncate, and the sides sloping. It falls far short of reaching the antennae. The median swollen portion of the face between the antennas, Mr. Fox had mistaken for part of the clypeus. The female of Neolarra pruinosa, which has never been described, differs from the male as follows : Length 4.5 mm. Abdomen brighter rufous, the 2nd, 3rd, and 4th segments not basally darkened. Last dorsal segment not strongly narrowed and produced as in the male ; but slightly narrowed to a blunt tip, shallowly concave above, the lateral margins raised, tip on either side with a strong, blunt, erect tooth. It seems possible from the description that Cresson's Phile- remusfulviventrts may also be a Neolarra. The genera and species discussed above may be listed as fol lows : PHILEREMULUS. VIGILANS Ckll. NANA Ckll. NEOLARRA. PRUINOSA Ash. VERBESIN^E Ckll. {Phileremus verbesince}. PHILEREMUS. Mr. Ashmead discussed this paper and said that Mr. Baker was perfectly correct in his conclusions. He himself in his original description of Neolarra, on account of the poor condi tion of the type, had mistaken its position. It is not a Bembecid, as he had supposed, but a bee, as claimed by Mr. Baker. Mr. Ashmead exhibited his type, to show by its poor condition that the mistake had not been so serious as might be supposed. He 24 ENTOMOLOGICAL SOCIETY further said that Haliday had considered the Bembecidae as rather closely related to the bees, on account of the structure of the mouth-parts. Mr. Ashmead also said that there was a strong affinity between certain wasps, the Larridcc and Nyssonidce, and some of the parasitic bees. //en ivunderbare Verivandlung, und sonderbare Blumen- nahrung, etc., 2 vols., Nurnberg, 1674-1683. t Metamorphosis insectorum Stirinamensium, etc., Amsterdam, i75- \De Buropiscke Insecten, etc , Amsterdam, 1730.

His work on insects is little more than a series of very excellent plates illustrating food-plants, early stages, and adults, with frequent parasites, and with single page descriptions of the plates, each of which is dedicated to some royal or noble person, sub scriber to the work. Brief descriptions are given of the different stages and the habits of the insects, and references are given also to the older authors who have treated the same insects. These with Reaumur were the great illustrators of the period, and their output represents a very considerable amount of the work accomplished in entomology. In looking over this period one is impressed with true fact that in the study of life-histories of insects, as typified by the work of Reaumur, Goedart, and Frisch, the results are as good as any since accomplished. In the study of the metamophoses, anatomy, and physiology of insects, which was almost pioneer work, and in the portrayal of insects and their transformations the period is also notable for its excellent output. In the beginning of a philo sophical classification of insects, Swammerdam and Ray's work, while very imperfect, cannot be overestimated as furnishing the basis and guide for the later and more satisfactory system of Linne. One witnesses also the beginning of wholesome original work and the final abandonment of the ancient superstitions relative to the origin of most insects. The work in general, therefore, of this pre-Linnean period is, much of it, of a most excellent character, and indicates that the science of entomology had intelligent and learned votaries and had reached a very advanced position long before the work of the great Swedish naturalist gave it a definite basis in nomenclature.

The noteworthy events of this period are the establishment of a binomial system of nomenclature by Linne in lieu of the old cum bersome descriptive clauses and the fixed definitions of genera and species by Linne, Schaeffer, DeGeer, Bonnet, Scopoli, and Clerck. In this and the later periods, time will not allow me to go much into detail. Linne's system of clasification, however, I will briefly describe on account of the interest which attaches to it in relation to and as an outgrowth of the older systems. His earliest classification of insects in the first edition of his Systema Naturcz (1735) is much inferior to the older systems of Swam- merdam and Ray, as the following statement of his four classes, illustrates : Class I. Four wings, of which the two upper are crustaceous (Coleoptera and Orthoptera) ............................. Coleoptera. Class II. Two or four wings, (Lepidoptera, Neuroptera, Hy- menopt-ra and Diptera) .................................. Angioptera. Class III. Four wings of which the two superior are half mem branous ......................................................... Hemiptera. Class IV. Without wings ............ ..................................... Aptera. The successive editions of this work vastly modified and im proved this table, and the form it assumed in the i2th edition (1767), which follows, has since been accepted for most of the orders substantially as he left it. f r c ..

Diptera, 6 o. Without either wings or elytra ........................... Aptera, 7 102 ENTOMOLOGICAL SOCIETY In all the editions of his work from the ist to the nth, Linne united the Orthoptera with the Coleoptera, but in the i2th edi tion the Orthoptera are placed with the Hemiptera, with which they have much less relationship. His Aptera contains not only the insects now usually so classed, but also certain lice, the fleas, spiders, mites, myriapods, etc. The other important systems of classification of this period are those of DeGeer and Geoffrey, both much inferior to that of Linne. The former, DeGeer, first employed the mouth-parts as n means of classification, and separated the Orthoptera definitely under the name of Hemiptera the true bugs being variously divided, but for the most part placed in the order Siphonata. He made in all 14 classes. Geoffroy gives 6 classes or orders and in the classification of the Coleoptera first makes use, as a means of separation, of the number of tarsal joints. In the anatomy of insects the work of Pierre Lyonet, an en graver of extraordinary ability and anatomist of the first rank, has not been approached in later years either in accuracy and minuteness of dissection or beauty of illustration, and is still the standard source of information relative to the larvae of Lepi- doptera. The very elaborate works illustrating insects and life-histories of the former period were continued in the present by Roesel von Rosenhof, Wilkes, Abbott, Sepp, Schaeffer, DeGeer, Geoffroy, and Bonnet. The latter, who was in a sense a pupil of Reau mur's, is to be remembered for having discovered the continued fertility of plant-lice in the absence of males, through many successive generations. Relating more particularly to the insects of America were certain papers by John Bartram, published in the Philadelphia Transactions, and the works of Pehr Kalm, whose travels in North America, published in Stockholm, 1753-1761, contain much interesting information relative to the common insects of this country at that early period, and, most important of all, the illustrations of Lepidoptera of Georgia by Abbott, published in part by Smith in ^97. The enthusiasm for the illustration of insects, represented by this period and the last, has never been surpassed in later years, OF WASHINGTON. 103 and is interesting not only from the excellence of much of the work, but from the fact, already alluded to, that these works seemed to be much in demand, often going through many editions. Group V. Pupils and Immediate Followers of Linne. The period following that of the contemporaries of Linne" and scarcely separable from it may be made to include Linnets pupils and immediate followers, and covers the very prolific 50 years, especially for descriptive and systematic entomology, between 1775 and 1825. The well-known names of this period are so numerous that it is impossible to refer to them in detail, and the increase of the number of persons who really accomplished notable results in connection with the many societies and journals devoted to en tomology which started about this time is an illustration of the inspiration which Linne produced. It must be remembered also that at this early period work in entomology, so far as it related to the characterization and naming of insects, was a comparatively new field, and that the collector in any new region had practi cally no need to trouble himself about whether or no a species had been earlier described. Much of the enthusiasm, therefore, is undoubtedly due to the fact that the material was ample and easy of access, and the difficulties which have resulted in later years from the separation of species into thousands of small genera and the more close and careful scrutiny of species them selves had not then arisen to make systematic work difficult. Some of the important names of the period follow : Pupils and Immediate Followers of Linne. (Writings: 1775-1825; born 1740-1790.) Esper (Eugen Johann Christoph). 1742-1810. Professor in Erlangen.

This list of names scarcely needs further amplification to the members of this Society, even if my time admitted it, to indicate the characteristics or value of the work accomplished. Promi nent in descriptive and systematic writings in general entomology are Herbst, Thunberg, Fabricius, Schrank, Latreille, De Jean, Spinola, and Say. In Lepidoptera, the names of Esper, Hubner, and Treitschke will be remembered ; in Diptera, Meigen, Fallen, Wiedemann, and Zetterstedt ; in Hymenoptera, Lepelletier, Gravenhorst, and Klug ; in illustrations and natural history, many of the above and also Kramer, Hubner, Olivier, Smith and Abbott, Humboldt, and Sturm ; in economics, Peck, Clark, and Bouche ; in anatomy, Dufour and Cuvier ; in gen eral entomology, Kirby and Spence and Panzer ; and as founders of entomological magazines, Illiger and Germar. Since I have referred especially to systems of classifications in the foregoing pages, it seems necessary to devote a paragraph to this subject in connection with this period also. The most emi nent names in this regard are Fabricius arid Latreille. The classification of Fabricius as he finally left it, containing 13 orders, all of which were newly named, was based solely on the character of the mouth-parts, which resulted in a general disasso- ciation of allied groups. His characterizations of genera and 106 ENTOMOLOGICAL SOCIETY species, however, hold for the most part to-day. Various attempts were made by Illiger, Oliver, and others to combine the systems of Linne and Fabricius, with results which were far from satisfactory, and no real advance was made until Latreille and the other systematic workers of his time, as Lamarck, Cu- vier, Kirby, and Spence, etc., gave their efforts to this subject. To Latreille, chiefly, however, the credit is due for the final proper limiting of the Class Insecta, and the separation of the groups represented by the Myriapoda, Arachnida, Crustacea, etc., which had hitherto been generally associated with insects, and especially for the establishment of a natural system of classi fication of insects based on a combination of the characters metamorphosis, wings, and mouth-parts formerly employed respectively by Swammerdam and Ray, Linne and DeGeer. Latreille should be especially mentioned also as the father of the family names as subdivisions of orders which were later given, as has been recently pointed out by Dr. Gill, uniform (patronymic) terminations on the recommendation of Kirby. This period overlaps and is really a continuation of the Lin- nean period. Thunberg, Fabricius, and others of this period were students of Linn6, at Upsala, and the former afterwards followed Linne" as professor of natural history. It will be noted that most of the distinguished entomologists of this period were either professors in universities or were physicians. Several of the important illustrators, as in the former period, were either painters or engravers. Treitschke was manager of the Royal Theatre at Vienna ; Clark was an English veterinary surgeon ; Douche" was a master gardener in Berlin ; Kirby was an English clergyman ; and Spinola was a Genoese nobleman. Group VI. The ityth- Century Writers. We now come to a generation which connects closely with the last and touches the one in which we live. It includes the authors born between 1790 and 1815. In this period the activi ties which were so marked in the last were continued with scarcely diminished zeal and prolificness. These two periods together are the great working eras in the history of the science OF WASHINGTON. 107 of entomology, and in glancing through Hagen's Bibliotheca it is seen that a large proportion of the important names in the science fall within these limits. The list of the chief writers of this period is herewith presented, arranged chronologically : Important i gift- Century Writers. (Born between 1790 and 1815.*) Straus-Duerkheim 1790-1865.

While this list includes the name of Darwin, who was born in the same year with Fitch and only two or three years later than Westwood, Agassiz and Burmeister, Darwin's epoch-making work, the " Origin of Species," appeared too late in his life (1868-9) to exert much influence on many of the writers listed. * Where date of birth is unknown it is estimated provisionally about 25 years earlier than first writing and inclosed in brackets. 108 ENTOMOLOGICAL SOCIETY Time does not offer to particularize the work done by the authors mentioned. In the descriptive and systematic field the workers were numerous. The general subject was covered by La Porte, Walker, and Gene. In Coleoptera were Eschscholtz, Mannerheim, Lacordaire, Mulsant, Chevrolat, Aube, Water- house, Schioedte, Murray, and Motschulsky. In Diptera, Des- voidy, Macquart, and Loew. In Lepidoptera, Schaeffer, Bois- duval, Zeller, Morris, Doubleday, andGuenee. In Hymenoptera, Brulle, Hartig, Shuckard, Smith, Kirchner, Dahlbom, and Walsh. In illustrations and natural history, Stevens, Passerini, Harris, Curtis, and Perris. In economics, several of those mentioned and Kollar, Guerin-Meneville, Ratzeburg, and Fitch. In anatomy, Strauss-Duerkheim, Audouin, Newport, and Bur- meister. In general writings, Stevens, Guerin-Meneville, Dun can, MacLeay, Newman, Westwood, Burmeister, Hope, Lucas, Walsh, Glover, Haldeman, LeBaron, and Costa. Hagen, the great bibliographer, and specialist in Neuroptera as well as in the general subject, though born somewhat later, belongs with this group of entomologists. I have not classified with the above a group of entomologists born a little later (1815-1850) but forming practically a continua tion of this group, and represented in part by the older living writers of the present day or immediately preceding the generation just beginning to take a prominent place in the science. This group covers the later life of Charles Darwin, and the workers of the period were more influenced by him, and their investigation and studies bear more directly on the difficult and intricate questions connected with biogenesis which his work brought into special prominence. Of these writers, prominent in the study of Coleoptera are Redtenbacher, Schaum, LeConte, Thompson, Blackburn, Crotch, Lindemann, and Horn. In Diptera, Snellen van Vollenhoven, Rondani, Osten Sacken, Schiner, Brauer, Bergenstamm, Mik, and Van der Wulp. In Lepidoptera, Stainton, Scudder, Ed wards, Clemens, Grote, Fernald, and many others. In Hem- iptera, Signoret, Stal. Douglas, Marshall, and Uhler. In Hymenoptera, Foerster, Kirby, De Saussure, Zaddach, Cres- son, Provancher, Bassett, Brischke, Mayr, and Holmgren. In OF WASHINGTON. 109 general writings, Gerstaecker, Leuckart, Leech, Donovan, Bates, Brauer, Kaltenbach, Taschenberg, Lubbock, Riley, Wallace, Packard, and Lintner. Scudder's work in palaso-entomology and Laboulbene's in anatomy should also be mentioned. This summary of the workers in entomology from the earliest period to our own generation has been most fragmentary and incomplete, but may be sufficient to indicate the great interest which the subject has always aroused, and furnishes a basis for the estimate which will be given later of the extent and character of the work which has been accomplished. The Literature of Entomology. That the accumulated writings on insects of all these centuries of activity make a very considerable mass of literature, hardly needs stating. It may be interesting, therefore, to make as care ful an estimate as may be of the actual amount of published matter which has resulted from these several hundred years of investigation and printing of results. The conditions, in the matter of available literature immedi ately prior to Linne, are somewhat indicated by Reaumur, who, writing in 1734, complains of the fewness of works in the French language which treat of insects and says that even in other lan guages the number is not great and the majority of them contain a large amount of observations for the most part made in such a manner as to please only those already interested in such studies, and not calculated to arouse interest in others. He mentions critically the writers of the periods preceding his own, most of whom have already been referred to in the preceding portions of this paper. In such ancient compiled works, however, as those of Pliny, ^Elien, Aldrovandi, Moufet, etc., the number of authors referred to is often very large in some instances including almost every important writer of antiquity. In the Theatrum Insectorum of Gesner, Moufet, et al., over 400 ancient authors are listed, many of whom, of course, referred to insects incidentally only. Pliny refers by name to less than a dozen Roman and foreign writers in the text of his chapter on insects, but he often mentions writers 110 ENTOMOLOGICAL SOCIETY in a general way without specifying the person or persons. In summarizing the authors quoted at the end of Book XI he men tions some 21 Roman and 25 foreign writers, but as more than one-half of the book deals with other animals, one-half of the references probably concern other subjects. As early even as the time of Reaumur, however, in spite of the latter's complaint of the dearth of literature, there must have been many entomo logical works if they could have been made accessible. Linne", only a few years after Reaumur, consulted or referred to some where between 75 and 100 authors, but mentions about 30 only as important (i2th edition), and Geoffroy towards the close of the same century (1799) refers to a little over 50 authors. Kirby and Spence, in the preparation of their Introduction to Entomology, consulted some 262 authors, referring among others to Lord Bacon, Erasmus Darwin, Oliver Goldsmith, Thomas Tusser, and Isaac Walton, and most of the old writers who have already been mentioned in the preceding pages. They also con sulted the transactions of some 14 societies and 19 periodical works, of which 4 only were strictly entomological, and these all in German. The vast number of entomological papers and works which began to appear about this time is indicated by the complaint of Lacordaire, writing early in the present century. He says : " Their number is such and they succeed each other so rapidly that one of the principal difficulties for those who cultivate the science seriously is to keep track of the innumerable publications which flood us from all quarters." Hagen's monumental work, " Bibliotheca Entomologica," brings the record of the literature relating to insects from the earliest times down to the year 1862. He lists some 4,766 au thors and enumerates 18,130 distinct titles, together with 851 anonymous publications. Vast as this collection is, it is neces sarily far from being a complete list of the writings on insects up to that time. It must be remembered, however, that a large percentage of the titles enumerated by Hagen relate to bees and silk-worms, and that many of the papers are very brief and un important. On the other hand, many of the works are very extensive, often amounting to many volumes, and it therefore OF WASHINGTON. 1 1 1 seems within bounds to estimate the number of volumes at one- half the titles enumerated or 9,000 volumes. This estimate leaves out the anonymous communications, most of which are short, and does not account for a great deal of fugitive writing which escaped Hagen's knowledge. There is no easy means of estimating the amount of published matter which has appeared since the time of Hagen's Bibliotheca, except in a little later data which he himself has given. That the annual additions of published matter, however, are enormous is shown by a brief examination of the yearly volumes of the Zoological Record, Zoologischer Anzeiger, Taschenberg's Bib liotheca Zoologica, and other similar works. In the last volume of the Zoological Record, that for 1895, 1,251 titles of publica tions on insects are catalogued, the mere description and indexing of which occupy 387 pages. In the year previous the number of titles was almost as great. A very conservative estimate of the amount of published matter which is thus added yearly to the stock of entomological literature, estimating roughly in 5oo-page volumes, places the number of such volumes at 75. That 2,000 volumes have been added to the stock of entomological literature during the 35 years since the publication of Hagen's Bibliotheca is, therefore, a conservative estimate. A form of literature which is not, or to a very slight extent, included in the above estimates is the economic phase of the sub ject, which, of late years, has assumed very considerable propor tions. In Henshaw's "Bibliography of the More Important Contributions to American Economic Entomology, " brought down to 1888, are included the names of over 500 writers and 5,424 titles. The publications, of this character, for the most part subsequent to 1888, by the State Agricultural Experiment Stations, established under the Hatch Act, were listed up to July, 1894, by Mr. Howard in the address referred to at the outset of this paper, and amount to about 300 separate bulletins and reports. Since that date, about 200 additional publications have appeared from this source. This large amount of so-called economic writ ings is much of it repetition and little of it is of such a character as to become a portion of the permanent literature of the science of entomology. The records of such writings in this country are 112 ENTOMOLOGICAL SOCIETY very complete, but in the similar economic literature of Germany, France, and other European countries the records have not been collected with the same pains, and most of the literature is unknown except in the limited districts in which it finds first circulation, but the combined bulk of it must be almost as great foi these countries as it is in the United States, especially in Germany, where forestry inspectors and entomologists are numerous, and in France, where agricultural and horticultural schools abound. From the foregoing data I do not think I am likely to exceed the truth in putting the bulk of the writings on insects available to-day at the equivalent of from 12 to 15 thousand volumes. This estimate does not include the recent literature of apiculture, the extent of which in later years may be gathered from the fact that, as listed for me by Mr. Benton, there are now some 63 journals devoted to this special subject, Germany standing at the head with some 30, the United States following with 8, and many other countries represented by from i to 3 or 4 each. The Number of Persons Interested in the Science at Vari ous Periods. Another field for estimate which has some interest is to deter mine the number of individuals at various times in the past who were interested in and wrote more or less on the subject of in sects. For the earlier centuries we have no means of estimating, with any accuracy, the number of working entomologists at any given time since the records relate only to the more important names. Some idea of their number may be gained by refer ence to the number of available works at various periods already given (seep. 109-110). To determine the number of individuals who are interested in entomology at the present time is also a difficult matter, since all available records are unsatisfactory. The volume of the Zoological Record for 1895 contains a list of 625 authors who dealt with insects proper, and 200 additional who wrote on Arachnida and Myriapoda. An examination of the volumes for the few years immediately preceding 1895 reveals three or four OF WASHINGTON. 113 hundred additional names in recent literature, so that from this source alone we have a record of probably 1,000 persons now living and writing on the subject of insects. The minutely divided subject-indexes, with consequent fre quent duplication of names of Taschenberg's Bibliotheca Zoologica, and similarly of the Zoologischer Anzeiger, Zoolog- ischer Jahresbericht or Bertkau's Entomologischer Bericht, make these sources of information useless for the purpose of esti mating the number of living writers. Many of the writers on economic subjects fail to be listed in any of these registers. The number of such writers for America alone is indicated by Hen- shaw's lists, already referred to, which enumerate 560 authors, most of whom are still living. It seems to me, therefore, reasonable to say that there are from twelve to fifteen hundred people now living whose writings on insects are of such a character as to be noticed in such standard annual works of record as the Zoologischer Anzeiger, Zoological Record, etc., with probably an equal number who fail of record or write more or less on purely local and economic subjects. This does not include the writers on bees to any extent. These figures leave out of account the very large number of collectors of insects who rarely, if ever, write on the subject. Perhaps the best available source of estimating this class of workers in entomology is Friedlander's " Zoologisches Adress- buch or International Zoological Directory," Berlin, 1895. From an estimate based on the index of this work, which in cludes both writers and collectors, it appears that some 4,800 persons are writing on various topics connected with the general subject of insects or are interested in collections. There are necessarily many duplications in this index, and, on the other hand, a great many omissions, but from this and the other sources of information named it is safe to assume that between three and four thousand persons living at the present time are sufficiently interested in entomology to get into the records, either as writers or collectors. However incomplete the foregoing estimates may be, both as to amount of published matter and the number of persons now interested in the science of entomology, and more or less actively 114 ENTOMOLOGICAL SOCIETY engaged in working up material or studying habits or investi gating questions in biology, etc., enough has been said to show somewhat the vast amount of interest which has been taken in the subject and the vast amount of work done. WHAT HAS BEEN, AND WHAT REMAINS TO BE, ACCOMPLISHED. What has been accomplished by all of this industry in the actual knowledge of the characters, habits, life-histories, etc., of insects has not been estimated, nor is it my purpose to attempt an analysis of the work of all these years, nor to discuss special fields of investigation. I wish, however, to draw attention to the phase of this subject covered by the description of species and genera, which, since the time of Linne, has commonly been the preliminary step. This brings me to the consideration of the probable number of true species of living insects, both as to those which have been described in the literature referred to and those which remain yet undiscovered or undescribed. It would be interesting, if time allowed, to estimate the number of insects which have been studied biologically, or the amount of work which has been done, as a means of understanding the anatomy of insects, and similarly for all the other fields of work in entomology, but I shall have to limit myself to the single consideration mentioned. Estimates of the Number of Species, Described and Unde scribed. That insects are very abundant is so self-evident that it proba bly never occurred to the early writers that it would be possible to estimate the actual number of distinct forms, or, at any rate, we have no such estimate until w r e come down to the time of John Ray. In his work, published in London about 1690, en titled "The Wisdom of God Manifested in the Works of Crea tion," Ray makes various estimates of the probable number of plants and animals, and estimates the number of species of in sects for the whole world at 20,000. In this connection it may be of interest to note that he places the number of beasts, in cluding serpents, at 150, and adds that, according to his belief, OF WASHINGTON. 115 not many that are of any considerable bigness in the known regions of the world have escaped the cognizance of the curious. The number of birds he estimated at 500. The smallness of all these estimates and the confidence which the author expressed in their completeness are interesting at this day and in the light of present knowledge. In the 1 2th edition of Linne's Systema Naturae (1767), on the authority of Dr. Sharp something less than 3,000 species of insects are listed, but no general estimate of the total number of species seems to have been made by Linne. We have records of various estimates made early in the present century. MacLeay estimated, about 1820, that the collections of Europe contained some 100,000 species of insects, which was accepted as correct by Latreille. Burmeister, however, estimates the number at 80,000. Taking this last figure as a basis, Lacor- daire (1838) estimates the proportion of the known species to the unknown by orders and arrives at the conclusion that the total number of species of insects is 362,000. This result he also proves ( ?) by an estimate based on the number of plants of the world. Taking De Candolle's estimate of plants for the en tire globe at 110,000 or 120,000 species and supposing that there would be on an average three insects to each plant, he finds the total of insects to be between 330,000 and 360,000. A little earlier Kirby and Spence, by a similar deduction, found the total number of insects to be 400,000, which figure Lacordaire con sidered to be too great. The only old estimate commonly quoted is that given by Dr. John Day, in a letter to Mr. Spence in 1853, in which the total number of insects is placed at 250,- ooo species, a very considerable advance on the number fixed by Ray, but much lower than the figures of an earlier period al ready quoted. A number of estimates have since been made by various writers, including Lord Walsingham, Dr. David Sharp, Profes sor Riley, and others. In 1883 Dr. Sharp said: ''As a result of a moderate estimate it appears probable that the number of spe cies of true insects existing at present on our globe is somewhere between 500,000 and one million." Dr. Sharp and Lord Walsing ham, in 1889, extended the number of species of insects to a prob- 116 ENTOMOLOGICAL SOCIETY able two millions. Professor Riley in 1892 made a careful esti mate of the number of existing species of insects on the globe, basing it on a careful computation of the number of species already described and the percentage of new species which are always turning up in collections in new or little worked territo ries. He placed the number of actual species at ten millions, and considered this to be a moderate figure. A very interesting statement compiled by Mr. Kenyon has recently appeared in the American Naturalist, giving in tabular form the number of described species of living animals in the different classes, as known in the years 1830, 1881, and 1896. This puts the number of described insects, excluding Arachnida and Myriapoda, at 49,000 in 1830, 220,000 in 1881, and 230,000 in 1896. Mr. Ashmead, in a former presidential address before this Society, estimated the number of described species of insects at 250,000. The records from which the 230,000 estimate just given was made are necessarily incomplete and it is probable that Mr. Ashmead's figure is the more nearly correct. In the statement just referred to in the American Naturalist the total number of described animals in all classes was only 366,000, and, as will be noted, insects with spiders and Myriapods repre sent nearly 250,000 of these, leaving only a little over 100,000 for all other animals. From these figures and Prof. Riley's estimate of the number of insects, it is apparent, as Mr. Kenyon suggests, that a reasona ble census of the whole animal kingdom would be about 15,000,- ooo living species, of which 10,000,000 would be of insects. It is interesting to note in this connection that Dr. Sharp has recently computed that in the matter of bulk insects probably outrank all other animals together, their small size being more than counterbalanced by the vast number of species and enormous number of individuals. If we take the estimate of the number of insects in the world at 10,000,000 as a reasonable one, and that at the present time 250,000 of these have been described and are preserved in collec tions and are known to entomologists, it will be seen that only i insect in 40 of the existing species is known, and this fact would seem to throw grave doubt on much of our classifications and OF WASHINGTON. 117 characterizations of genera, particularly in the groups of the smaller species, and especially when we remember that the dis coveries of every year cause constant revision of previous studies in both of these particulars. The vastness of the field of entomology is indicated by the fore going figures, and that the field is practically inexhaustible from the present standpoint seems to be also fully demonstrated. Present Rate of Description, and Probable Time of Com pletion of the Work. It is an interesting problem to determine how many years more it will take to describe the insects of the world at the present rate of progress. The activity in collecting and describing insects has never been greater than at the present time, and the number of workers is being increased yearly ; but as the more accessible regions of the world are worked over, the securing of new species will become more and more difficult and it is reasonable to sup pose that even with the constant increase in the number of students of insects the rate of description of new species will probably never very much exceed the present. Taking the Zoological Record as a basis for computation (and the records therein given are not at all complete), it appears that during the last few years there has been an average of i ,000 new genera and subgenera of insects described yearly, not including the Arachnids and Myriapods, which would add 200 additional genera. This makes a total of 1,200 new genera yearly out of a total for all animals (that is, including insects) of some 1,700 genera. The number of new genera added yearly is somewhat astonishing when it is remembered that Linn had altogether but 74 genera of insects. Some ten years since, Dr. Sharp estimated that during the last 120 years, or since the time of Linne, an average of about 2,000 new species of insects had been annually described. Taking the results of the more recent years as a basis, Lord Walsingham has estimated the number of species now described yearly at 5,000. This is after deducting 8 per cent, for possible synonyms and is considerably below the annual increase indicated for the last 36 years in our recent quotations from 118 ENTOMOLOGICAL SOCIETY the American Naturalist. If the present rate, therefore, of descrip tion of species be kept up it will require upwards of 2,000 years to finish the work of collection and classification of insects. That the entomologists of the world have ample material with which to work and that there is no alarming pros pect in the immediate future of exhaustion of the field is strikingly apparent. If time allowed, it would be of interest, perhaps, at this point, to give some statistics relative to the great collections of insects in museums or in private hands, but further estimates and figures would probably weary you, and I shall, therefore, hasten to the conclusion of this paper. CONCLUSION. It is no longer necessary for the student of entomology to defend his favorite science. The world at large has come to appreciate the importance of such studies and the benefits which may be derived therefrom, both in matters of economics and as a means of appreciating and understanding the general laws which affect all nature.* In the light of present conditions, therefore, it is interesting to recall the estimation in which the entomologists were held by theii contemporaries of the early days. That he was considered "queer" goes without saying. That he was liable to the charge of actual lunacy was demonstrated by not in frequent experience, and in some quarters of the world, for that matter, such views have not entirely disappeared. Illustrating some of these inconveniences of the early days is the incident reported, on the authority of Kirby and Spence, by Moses Har ris, who records an attempt in the i7th century to set aside the will of a certain Lady Glanvilles on the ground of lunacy as evinced by no other act than her fondness for collecting insects, and it was necessary for John Ray, the great zoologist of that period, to appear at Exeter during the trial as a witness to her sanity. * Referring to his own career as a collector and that of two or three others who afterwards became famous, Darwin says : " It seems, therefore, that a taste for collecting beetles is some indication of future success in life ! " OF WASHINGTON. 119 The great significance of small things has come to be appre ciated in the present generation more than any other, and Ray's evident feeling that animals are important in proportion to their bigness, as indicated by his remark in connection with his estimates of the number of species of animals, finds no place in the present generation. The small things are now the important ones, and the student of microscopic forms of life has a much more useful field than the student who investigates the grosser forms. Size is not so significant as number, and in this respect insects hold the mean position, and with them it is true also that the smaller species are usually the more important ones, both economically and as objects of scientific study. In the various fields of biologic investigation which have resulted from the work of such men as Darwin, \Vallace, and Weismann, insect studies have played a very important part. The vast number of species, the ease with which they can be collected and studied, their short life-periods and fecundity, all are phases which greatly facilitate the investigation of such prob lems as those of Heredity, Protective Resemblance, Dimorphism, Natural Selection, Zoogeography, and various other matters con nected with biogenesis. It is an interesting fact also that the great names in zoological science are either of entomologists or of persons who were greatly interested in the study of insects. Aristotle, Ray, Linne,'Cuvier, Lamarck, Darwin, Wallace, and many others who have been epoch-makers in the science of zoology w r ere enthusiastic students of insects. Other than the more purely scientific side is the practical or economic phase of the study of insects. This field I shall not enter. It has already been covered very largely by the paper by Dr. Howard cited at the outset, but I simply wish to call atten tion again to the very great interest in this department of the study of insects which characterizes the present generation and to refer in this connection to a remark of Reaumur's way back in the early history of entomology in which he commends a course of pro cedure which is pertinent at the present day. He says that "it seems to me that the insects which fall under our eyes most often are the ones which we ought most to study. They are the ones, 120 ENTOMOLOGICAL SOCIETY so to speak, with which we have to live." It was on this basis that he carried out his great work on insects, and it is a fact, which we are beginning to appreciate more in recent years than formerly, that we often know very little about common insects or those, as Reaumur says, with which we have to live, and that in the species which we meet every day is a field for study and investigation that is often almost unworked. Of the mil lions of species which exist in the world a vast percentage of them have little importance other than that of filling the gaps in some system of classification, and it seems reasonable, therefore, to urge the importance of working on common insects, especially in view of the fact that it will be hundreds of years before any complete knowledge of the whole field can be gained. The classifications and descriptions of to-day, on which have been expended vast time and energy, will be antiquated in a few years with the advance of science and discovery of new forms, and their places will be taken by new systems of classification and new descriptions. That an at least equal permanency and a greater practical value attaches to work in the lines of investi gation of life histories and habits of common species and studies of anatomy and the more general problems of biology, is the opinion of the writer. These questions, however, are perhaps controversial and it is probably unwise to introduce them. The address was discussed by Messrs. Gill, Ashmead, How ard, Kenyon, and Schwarz. All of the speakers congratulated the President upon his address and thanked him for the pleasure he had given the Society. Dr. Gill combated the idea that Aristotle derived any great benefit from his association with Alexander the Great. A close study of Aristotle's works shows no basis for the statement, which was derived from the writings of later authors. All of the forms described by Aristotle from specimens are familiar Grecian forms. Everything which was not Grecian was de scribed from hearsay. That Alexander gave Aristotle 8 talents in gold (amounting to about one million of dollars) is manifestly OF WASHINGTON. 121 absurd, since this sum of money exceeded the entire revenue of Macedonia. In the following period Dr. Gill would give more attention to the writings of Gesner than to those of any of his contemporaries. Gesner was the first to give generic names, and his descriptions were more detailed and of a better char acter than those of other writers of the period. In the Ray period he would give prominence to Lister as a writer rather than as but an editor of Ray's works. In periods 4 and 5 he would make a marked distinction between the servile followers of Linne and those who thought for themselves, as Fabricius, for example, who started the movement which perhaps culminated in Latreille, the author who first conceived the idea of a family in zoology. As to the estimate of the number of species of animals, he expressed great scepticism concerning the correctness of Riley's estimate of ten millions. We know most of the mammals and birds of civilized regions, and although the fishes and mollusks of the deep seas are perhaps not more than half known, it is out of the question to consider, for a moment, that we know only 2,]/2 per cent, of the species which exist on the globe. He further mentioned an estimate of the number of species which had been overlooked by Mr. Marlatt, viz., that of Agassiz, in his " Elements of Zoology." He further called attention to the important anatomical work of Strauss-Durckheim. Mr. Ashmead spoke briefly, emphasizing the influence of Ray's system on modern systematic entomology. He thought that Ray is not sufficiently appreciated to-day and some of his work still holds. Mr. Howard discussed briefly some of the authors mentioned by Mr. Marlatt, giving a few additional facts of general interest, referring, among others, to the fact that two great-great-grand sons of Jacob Schaeffer are living in Washington to-day. He criticised mildly the method of computation of the amount of entomological literature in existence, particularly the method of computing from the titles in the Zoological Record, and stated that in his opinion the estimate of 12,000 volumes of 500 pages each is too high. This statement was at once attacked by Dr. Gill and by Mr. Marlatt, who gave reasons for considering the estimate as not at all too high, and, in fact, possibly too low. Mr. Kenyon expressed himself as glad to have his table of 122 ENTOMOLOGICAL SOCIETY known species, published in the American Naturalist a year ago, confirmed by Dr. Gill and Mr. Marlatt. He spoke of the work of the new school of biologists which will unquestionably unsettle classification in many important respects, so that we are at the present time in an uncertain position. Mr. Schwarz stated that no prominence must be given Pliny as a naturalist. It appears that the Romans had no natural- history sense whatever. Pliny was not a naturalist, but for many years was a collector of notes from Greek authors. It is as a preserver of these notes solely that he must be remembered. Discussing the question of the number of species yet to be described, Mr. Ashmead spoke of the extremely small propor tion of the micro-hymenoptera which have yet received attention. New species may be everywhere found, even in the best known localities. In his monograph of Proctotrypidas three-fourths of the forms treated w r ere new. Yet he considers that this mono graph contains not a sixth of the forms which exist in America. He spoke of Mr. Cockerell's recent monograph of the genus Perdita as illustrating the condition of some of the groups of aculeate hymenoptera. Mr. Schwarz illustrated an important element which must enter into the question of the number of species by speaking of the genus Carabus. In Europe 50 years ago a certain number of species, represented by, say, 3,000 specimens in collections, were recognized by the best Coleopterists. To-day most of the varie ties of the same number of species are recognized as valid species and the total number of species has more than quadrupled out of the same number of specimens. How can we estimate the number of species if our conception of what is a species be constantly varying? >^Av MARCH iSxn, 1897. President Marlatt in the chair, and Messrs. Heidemann, Pratt, Karlsioe, Linell, Gill, Benton, Patton, Busck, Schwarz, Ash- mead, Johnson, Motter, and Howard also present. The following new corresponding members were elected : Mr. OF WASHINGTON. 1 23 Frederick Blanchard, Tyngsboro, Massachusetts ; Mr. August Merkel, 13 Broadway, New York city; Mr. Malcolm Burr, "Bellagio, " East Grinstead, Sussex, England. Mr. Schwarz announced the death of Dr. John Hamilton, of Alleghany city, a corresponding member. Under the head of "Short notes and exhibition of speci mens, " Mr. Ashmead showed specimens of Halobatopsis beginii, recently described by him in the Canadian Entomologist. Dr. Motter read a letter from Dr. Wyatt Johnson, of Quebec, giving an account of the investigation of the fauna of cadavers in Canada, which had been carried on by the writer and Dr. George Villeneuve, showing a considerable correspondence with the results obtained by Megnin in Europe. He also read a letter from Garry de N. Hough, of New Bedford, giving an account of investigations in the same direction. Dr. Motter showed that the results obtained by these investigators differed considerably from his own, and accounted for this difference by the fact that the Canadian workers had experimented mainly with exposed human bodies, Mr. Hough had studied mainly the exposed bodies of animals, while he himself had studied in the main interred bodies. Mr. Heidemann exhibited specimens of Fitchia nigrovit- tata, F. aptera, and F. spirosuta, the first two from the Dis trict of Columbia, and the last from Fortress Monroe. Mr. Busck exhibited six larvae of Anthrenus varius, each of which showed well-marked wing-pads on the second and third thoracic segments. In discussing these specimens, Mr. Schwarz stated that most monstrosities are retrograde in their character and that anticipatory monstrosities such as those shown by Mr. Busck are very rare. He called attention to the parallel case recently published by Dr. Richard Heymons, of Berlin, in which similar wing-pads had been found in the larvae of Tenebrio molitor. Mr. Pratt said he had occasion to examine recently many hun dreds of larvae of T. molitor and had not found any such cases. Mr. Howard referred to the fact that while Dr. Heymons was inclined to explain the appearence of the wing-pads of the larvae of the meal worm as anticipatory of the pupal condition, he also mentioned the possibility that they were atavistic in their significance. Mr. Ashmead was inclined to think that the latter theory may be the correct one. 124 ENTOMOLOGICAL SOCIETY The Secretary read the following note, submitted by Mr. T. D. A. Cockerell : INSECTS IMPALING THEMSELVES. By T. D. A. COCKERELL. While the insects impaled on thorns by shrikes are familial- objects, it seemed to me, when the subject was under discussion, that the probabilities of an insect ever impaling itself must be very slight. Therefore, it seems worth while to bring before you a couple of instances just communicated to me by eye-witnesses, whose veracity I do not in the least doubt. Mr. C. W. Alexan der tells me he has seen the big lubber grasshopper which is common in this region impale itself on the sharp leaf of the broad-leafed Yucca at the Gold Camp, near the Organ Mountains. Mr. R. E. Condit, when driving by Coats Creek, in S. W. Colorado, found numbers of large black crickets which, in their haste to escape from the feet of the horses, jumped against the cacti lining the road, and many of them were impaled on the spines. The following paper was presented by Mr. Ashmead : DESCRIPTIONS OF FIVE NEW HYMENOPTEROUS PARA SITES ON CANARSIA HAMMONDI (RILEY). By WILLIAM H. ASHMEAD. The descriptions of the following new species were drawn up some two years ago at the request of Prof. S. A. Forbes, of the Illinois State Laboratory of Natural History, to accompany an article by Prof. W. G. Johnson, on the habits of Canarsia hammondi, and represent only a small proportion of the para sites reared from this moth. FAMILY ICHNEUMONID^E. Spilocryptus Thomson. Spilocryptus canarsise, sp. n.

Types in Illinois State Laboratory of Natural History. Described from i cP and i 9 specimen bred September 6 and 21, 1894, by W. G. Johnson, from Habrobracon (Sracon) gelechice Ashm. and the primary parasite of Canarsia ham- mondi. In discussing this paper, Mr. Johnson spoke of the great injury which Canarsia hammondi had done to young apple trees in McLain county, Illinois. In one season damage to the amount of $1,500,000 had been done. One block of trees containing 125,000 had been completely destroyed. He found, among other interesting facts, that this insect pupates in the ground and not in the leaves, so that Riley's recommendation to burn the leaves as a remedy is ineffective. In the course of his investiga tions, he reared 13 species of parasites, all but one of which were hymenopterous. Of the 12 Hymenoptera, 10 were primary para sites. He gave some rearing notes concerning these 10 species and showed that Habrobracon gelechice was the most important, and constituted in number of specimens four-fifths of all which were reared. The habits of this species were given in full, show ing that only 12 days elapsed in the development of the insect from the egg to the adult. Among other species, he mentioned a Perilampus as a primary parasite, and this record was at once questioned by Mr. Howard, who suggested that the insect was more likely to have been a parasite of the Chrysopa which had crawled into the Canarsia cocoon to spin its own cocoon. Mr. Johnson stated that he had not examined the Canarsia cocoon from which this insect emerged. Mr. Ashmead consid ered it more likely that the Perilampus had been a parasite upon the dipterous parasite reared by Mr. Johnson. The following paper was read : 132 ENTOMOLOGICAL SOCIETY A NEW SPECIES OF ROPTRONIA. By WILLIAM H. ASHMEAD. The following new species in the rare genus Roptronia Prov. was taken by Prof. H. Garman, of the State College of Ken tucky, at Lexington, Ky., and after whom I take pleasure in naming the species. The genus, as originally described, was placed by Abbe Pro- vancher in the family Braconidce, but was subsequently removed by him to the subfamily Helorince in the Proctotrypidcz. From the imperfect figure of the venation given by Provancher, and before I had seen a specimen for examination, I was inclined to doubt the correctness of this last view of the learned Abbess, and placed the genus doubtfully among the aberrant group Pachy lommatince in the Braconidae. Since that time, however, I have seen three representatives of the genus, and a careful study of these specimens convinces me that Provancher was correct in removing the genus to the Helorinae. The venation is somewhat similar to the genus Monomachus Westw., and seems to afford a connecting link between this genus and the genus Proctotrypes Latr. Monomachus should also be placed with the Helorinae. Roptronia garmani, n. sp. (j\ Length 7.5 mm. Black; head and thorax rugoso-punctate, pubes cent; front coxae, except a spot at base beneath, trochanters, except spot above, tips of femora and anterior tibiae and tarsi, spot at apex of middle coxae, second joint of trochanters, tibiae beneath and narrowly at base and apex and their tarsi, second joint of hind trochanters and basal one- third of hind tibiae, pale ferruginous or pale yellowish; tegulae and pro- thoracic tubercles ferruginous. Head transverse-quadrate, the temples as wide as the eyes ; mandibles dull ferruginous, bidentate at apex, the upper tooth longer than the lower; maxillary palpi 5-jointed, labials 4- jointed, the last joint dark fuscous. Antennae 14-jointed, filiform, taper ing off at apex. Thorax, with the mesonotal furrows rather broad, dis tinct, slightly crenulate, especially posteriorly; metathorax rugose, rounded off posteriorly, the spiracles small oval. Abdomen with a long petiole, the petiole being fully as long as the hind femora, or slightly longer, shining, but fluted above, and somewhat rugose basally, smoother and punctate towards apex and beneath, pubescent, body of abdomen com pressed, viewed from the side somewhat triangular, about as long as the petiole, highly polished, the first segment occupying fully two-thirds the whole length, the following segments short, subequal.

OF WASHINGTON. 133 I add below the description of another species discovered among the collection of Braconidce, belonging to the American Ento mological Society, now in my hands for examination and study. Roptronia californica, n. sp. <$. Length 5.5 mm. Pale ferruginous; spot on vertex enclosing the ocelli and extending forward to base of antennae, occipital foramen, clypeal spiracles, prothorax above anteriorly and beneath, mesopleura, meta- thorax and abdominal petiole, black ; eyes brown ; antennae, except pedicel, brown, i4-jointed ; legs pale brownish-yellow; wings hyaline, the stigma and veins brown. This species structurally does not differ greatly from R. garmani, except in having the head, except vertex and face, the mesonotum and the scu- tellum, except at apex, smooth and almost impunctate; the mesopleura, except space beneath wings, are closely punctate, while the metathorax is rugose. The venation is almost identical in the two species, except in californica, the first abscissa of the radius is perpendicular and not longer than the width of the stigma, while in garmani it is oblique and more than twice longer than the width of the stigma. Another character not noted in the other two species is that the postscutellum is conically produced, viewed from the side its apex reaches an elevation above the disk of the scutellum. Hab. Southern California. The three species now known in this genus may be tabulated as follows : Head and thorax black, rugose ; postscutellum normal. Abdomen black ; legs, except tips of anterior and middle femora and their tibiae and tarsi, mostly black. $. Length 7.5 mm. R. garmani Ashm.

C. PART I. NOTES ON PARASITIC HYMENOPTERA. By Dr. GEORGE DIMMOCK. The following notes concern parasitic hymenoptera, mostly reared species, for the identification of which I am indebted to Mr. W. H. Ashmead, whose article accompanying this paper will describe the species that proved to be new, and which are indicated by a * against the abbreviation Ashm. The data which pertain to each species are fragmentary, as many of the parasites were the accidental results of attempting to rear their hosts. Dates of emergence, and locality, are of some importance, and are quite fully noted : the locality N. H., in all cases, signifies Canobie Lake, a village about five miles north of the state line of Massachusetts, between the towns of Windham and Salem, in Rockingham county, New Hampshire. The numerals in parentheses refer to my manuscript notes, and correspond with numbers on the specimens preserved. FAMILY PROCTOTRYPID^E. (1) Telenomus dimmocki, *Ashm.

Numerous specimens, in latter half of Sept., from a breeding-cage of larvae of Zerene catenaria, in N. H. ; as these larvae were badly parasitized by tachinids, it is likely that the chalcids were, in this case also, parasites of the tachi nids. (674, 934.) (7) Encyrtus thyreodoniis, *Ashm. A larva of Smerinthus exccecatus, taken 8 Sept., 1882, in Cambridge, Mass., that went under ground for pupation 3 Oct., was dug up later, and found to be parasitized by Thyreodon morio. From the cocoon of the Thyreodon emerged, April, 1883, a large number of E. Thy reodontis, of which 170 specimens were preserved and many lost. On 6 Sept., 1882, a female E. thyreodontis was watched while apparently ovipositing in a larva of S. exccecatus ; both larva and chalcid were preserved, and the former produced a healthy normal male imago, not producing chalcids, perhaps because it had not been parasitized previously by a Thyreodon to provide a suitable host. Another E. thyreodontis was ob served stinging a larva of Attacus cecropia ; this larva died later, possibly of some bacterial disease, but no chalcids came from it. Were the two presumably resultless ovipositions cases of mistaken instinct? (340, 345, 563.) (8) Homalotylus terminalis, Say ( = Scelio terminalis Say = H. obsctirus, How. = Eutelus scymnce Schimer).

President Marlatt in the chair and Messrs. Ash mead, Patten, Gill, Schwarz, Motter, Pratt, Johnson, Benton, Kenyon, Busck, Banks, and Howard also present. Under the head of "Exhibition of specimens and short notes," Mr. Johnson showed Tribolium madens, a species w r hich had been sent to him from Montana in mill products. This is the first record of such a habit in this northern species, and he also said that he had found the previously unknown larva of this species. He further showed a parasite of Gelechia cereal- lela caught in the act of oviposition. Mr. Ashmead determined this as probably a species of Dibrachys or Catoloccus. Mr. Schwarz showed specimens of Trigonoscuta pilosa, a maritime species collected by Mr. Hubbard at Palm Springs, Cal., and stated that Mr. Ulke possesses specimens of Cercyon jimbriatum which may also come from this locality. This latter species is also maritime, and Mr. Hubbard's finding tends to substantiate the theory that the Colorado desert was formerly an arm of the sea. Mr. Schwarz also showed a fragment of a specimen of a Dynastid genus new to North America and apparently allied to Golopha. This was found in the great mesquite forest south of Tucson, by Mr. H. Brown. He discussed the entomological evi dence in regard to the supposed tropical character of the fauna of the lower Colorado Valley, and showed that, while many new 172 ENTOMOLOGICAL SOCIETY species are found there, only 5 or 6 genera of a tropical character have as yet been collected, and the evidence is insufficient to prove the region to belong to the neotropical. His remarks were based mainly upon the recent collections of Mr. Hubbard, who has captured more Coleoptera at Yuma than any other one collector. These specimens, however, were captured in the winter time, and summer collecting might produce stronger evi dence in favor of the tropical idea. The speaker suggested that close collecting, if it were possible in the great mesquite forests southwest of Tucson, or in the Colorado desert itself, might show that the tropical elements enter our territory at these points rather than in the immediate valley of the Colorado River. Mr. Howard exhibited specimens of a new genus of Mono- phlebinae taken by Mr. Hubbard on the creosote bush at Palm Springs, and said that the only American representatives of this subfamily of scale-insects are neotropical and that therefore this finding had some significance as substantiating Dr. Merriam's statements that this region is tropical. Dr. Gill agreed with Mr. Schwarz and said that he did not think Dr. Merriam justified in mapping this region as tropical. He does not think, even with the forms which most guided Dr. Merriam, viz.', the mammals and birds, that the evidence is com plete. The fish fauna of the lower Colorado is poor, but all the forms are temperate in their character. The reptiles of the re gion offer the best evidence in support of the tropical idea, but even this is inconclusive. Mr. Schwarz exhibited further a curious spiny Psyllid which belongs to the genus Rhinocola, which Mr. Hubbard had collected in the same region, and spoke of the spiny character of the plants of the region and the apparent correspondence of the spiny armature of the insects'. Mr. Marlatt asked as to the connection between the spinosity of the plants and the insects. Mr. Ashmead considered it to be a plain case of protective resemblance and referred to the pecu liar Heteropteron Pronotacantha as a species which profited in this way. Mr. Schwarz said that an insect living on a spiny plant is protected by the spines of the plant itself and theoreti cally needs no spines of its own. Mr. Marlatt said that with so OF WASHINGTON. 173 small an insect as the Rhinocola, in which the spines were micro scopic, there could be no protective resemblance to plants. Dr. Gill said that the distribution of spines upon an insect would affect the play of the light and thus enable it to assimilate with its surroundings. Mr. Marlatt was of the opinion that these spines would prove to be of secondaiy sexual value and that their occurrence is not due to protective resemblance. Mr. Benton exhibited specimens of Apisjaponica which had been sent to the U. S. Department of Agriculture by Professor Matsumuri, of Japan, and pointed out the differences between this species and Apis mellifica. He thought that its greater pubescence would make it a better pollenizer and that it would prove to be an active and energetic worker, so that possibly it might be well to introduce it into North America. Mr. Banks exhibited four rare species of Caddis flies, namely, Neuronia pardalis Walk., Neuronia dossuaria Say, Halesus argus Harris, and Neophylax concinnus McLach. He pointed out the resemblance of the second species to a scor pion fly and thought that this might be a case of protective mimicry. He further spoke upon the interest attaching to the Trichoptera through their close relationship with the Lepidop- tera, which has recently been established. The following paper was presented : -f THREE NEW SPECIES OF CHRYSOPID/E. By NATHAN BANKS. The lace- wing flies of the northeastern United States are proba bly mostly described, but those of the South and West have been little studied and doubtless will furnish many new species. The group is of much interest on account of its curious habits and life-history, and is also of considerable economic importance owing to the predaceous habits of the larvae. Chrysopa. oculata has occupied in economic respects a place similar to that of Lachnosterna fusca. And just as the later studies of the May-beetles revealed many forms, so also the study of our golden-eyed or lace-wing flies will show that there are other species of nearly as much value as Ch. oculata. The species of Chrysopa are exceedingly difficult to separate ; the venation being remarkably constant in the various species, and other structural characters are of little avail. 174 ENTOMOLOGICAL SOCIETY . Recourse has been taken to the markings of the head, which furnish, in most cases at least, a basis for natural classification. In this respect the genus is very similar to CEcanthus, in the crickets. As to the exact value of these cephalic markings, there will, of course, be various opinions. I have believed that Fitch carried it to an extreme, and that several of his so-called species are not entitled to specific or varietal rank. Yet these markings are of value, for in forms that to the eye appear certainly distinct the best characters for separation will be found to be these mark ings of the head. Two of the species I describe below are from Colorado, both rather closely related to known forms ; the one to the eastern Ch. lineaticornis Fh. ; the other to the southwestern Ch. punctiner- vis McLach. The third, a species of Leucochrysa, comes from Alabama. All three have been collected by Prof. C. F. Baker. Chrysopa sabulosa, n. sp. Green ; face yellowish, a short black stripe under each eye, broadest at tip, near the inner end is a small black dot ; just below the antennae is a transverse black mark. Above on the green vertex are two round black dots ; the palpi are black. The antennse beyond the second joint are black on their basal half ; the basal joints are short and close together, and with a black stripe on the outer side, and a large black spot below. The pro- thorax is green, unspotted, very short, with a transverse furrow behind the middle. Thorax, legs, and abdomen pale green. Wings hyaline, with green veins, some transversals partly black, the divisory of third cubital black. Tip of wing broadly rounded, pterostigma quite distinct. Alar expanse 24 mm. One specimen, Ft. Collins, Colo. Differs from Ch. lineaticornis in more spotted head, in the large spot on lower side of basal joints of antennae, in black divisory veinlet, and in shape of prothorax. A Chrysopa fraterna, n. sp. Yellowish, marked with dark red brown. Face i-ather greenish, a short black stripe under each eye, and each side of labrum an elongate spot ; a reddish band across the base of labrum and a spot in the middle. Two black lines between the antenna, diverging above, each side of venter near the eye is a black spot. Palpi broadly banded with black. Basal joint of antenna has a dark spot on inner side, and two lines above, second joint with a black ring, rest of antennse pale. Thorax broadly margined each side with a red-brown stripe and a narrow line on the middle. Legs pale, a brown dot under tips of the anterior femora, and a band just before tip on posterior femora. Abdomen much spotted with dark red-brown. Wings hyaline, the subcosta, sector, cubitus and postcubitus dotted with brown ; the transversal wholly dark. Tip of wing rounded ; the sector of radius curves but slightly toward the radius. OF WASHINGTON. 1 75 One specimen, Ft. Collins, Colo. Closely related to Ch. ptinciinervis, but larger and differently marked ; quite noticeable by the band on hind femora. Leucochrysa americana, n. sp. Pale greenish. A transverse reddish spot under each antenna ; above is a transverse red line bent downward in the middle, and giving off a spur between the antennae. Vertex with two deep depressions. Antennae wholly pale, longer than wings, basal joint short and stout. Prothorax short, narrowed in front; with a short black spot in the middle of the front margin, and a reddish-brown line on each anterior side. Legs pale. Abdomen pale, with a large reddish spot on the last ventral segment, and a dot on each side on the genitalia. Wings hyaline, rounded at tips; the hind pair narrowed and more acute; the pterostigma brownish, distinct. The third cubital cell much longer than the second, not very much broader; the divisorj veinlet arising from quite near to the postcubitus. The sector of the radius is very mUch nearer to the radius at pterostigma than in the middle of its length. Alar expanse 27 mm. One specimen, Auburn, Ala. Easily separated from L. floridana by its smaller size and different markings. In discussion Mr. Schwarz referred to the fact that we badly need synoptic tables of the lace-winged flies the published descriptions are so widely scattered. Mr. Banks spoke of the characters used in classification and showed that for specific separation the characters are almost entirely colorational. Few or no structural characters of specific value can be found. Mr. Ashmead stated that he had studied these insects to some extent and believed that if carefully studied venation would show characters of value. Mr. Banks expressed himself as of the opinion that the venational characters are absolutely worthless. He showed that the two fore- wings of the same individual may differ in venation. Mr. Ashmead stated that the same difficulty exists with the dragon flies and with the Orthoptera, but that with prolonged study, even with this difficulty, Saussure has ascertained many excellent venational characters with the Orthoptera. Mr. Marlatt said that a complicated venation should always be approached with caution and that in his opinion venation varies within specific limits in direct ratio to its complication. He 176 ENTOMOLOGICAL SOCIETY stated that he had noticed that the eggs of the different Chrysopas are variable both in length of stalk and in method of placing and suggested that the species might be separated in this way, Messrs. Schwarz and Ashmead having previously pointed out the varia bility of the larvas of these insects. OF WASHINGTON. 1 77 MAY J 3' lS 97- President Marlatt in the chair and Messrs. Schwarz, Coquillett, E. F. Smith, Busck, Fernow, Banks, Patten, Motter, Pratt, Gill, Ashmeacl, Howard, and Dr. Clifton Mayfield also present. The President announced the death, on May 3d last, of Martin L. Linell, an active member of the Society, and made a few remarks appreciative of the value of Mr. Linell's entomological works, of his good qualities as a man and of the loss to the Society from his death. Upon motion of Mr. Howard, it was resolved that the Society publish a short sketch of Mr. Linell's life and work with a bibliography of his published entomological writings, and also a brief manuscript found upon his desk which will be entitled k4 Descriptions of New Heteromerous Coleoptera from North America." MARTIN LARSSON LINELL. Little is known of the early life of Linell, and the following data are taken from a short obituary note published by Mr. F. H. Chittenden in Entomological News (vol. 8, No. 6, p. 159): Martin Larsson Linell was born at Gronby, Sweden, June 24, 1849. At an eai "ly a g e ne became interested in the study of nature and made collections of Swedish insects and plants. In the year 1870 he entered the university at Lund, where he distin guished himself by his proficiency in mathematics, biology, and languages. It was his father's intention to fit his son for the ministry, but young Linell abandoned the university career at the end of his third year and entered the railway mail service. In 1879 he married and came to America, where he obtained em ployment in a chemical laboratory at Brooklyn, N. Y. In his spare time he resumed his entomological studies and formed a collection of Coleoptera. He soon established for himself the reputation of being the best systematist among the New York entomologists. In iSSS he was called to Washington as an aid in the Department of Insects at the U. S. National Museum. 178 ENTOMOLOGICAL SOCIETY Before Linell's entrance into this office very little work had been done in arranging the vast material of insects at the Museum, excepting the Lepidoptera, which had been for some time in the charge of Mr. J. B. Smith. In bringing order in the collection, Linell's remarkable qualities as a working entomologist were clearly brought out. Hitherto only occupied with Coleoptera, he was able, within an incredibly short time, to master the intricacies of the classification of other orders so that in the course of a few years he managed to bring order into the entire collection. Very few persons are aware of the enormous amount of work ac complished single-handed by Mr. Linell, work of a most thank less nature, which left him no time to publish anything for himself. However, when the Department of Insects was placed under the curatorship of Dr. L. O. Howard, a better time dawned for Linell, since, by the employment of assistants, he was relieved, to some degree, of the tedious manual work which is inseparable from the maintenance of a large collection of insects. He now found time to return to the study of his favorite order, the Cole optera, and commenced to publish papers which in quality are certainly above the average work done in descriptive entomology. But he enjoyed this most happy period of his life only for a short time, and on May 3, 1897, he died suddenly of heart failure. After years of toil for others, he was just entering upon systematic work for himself, when death came. The last few papers illus trate his rare ability and judgment as a systematist, and had his life been spared he would doubtless have soon stood well up in the ranks of the world's Coleopterists. Mr. Linell was not only well versed in the broad field of gen eral science, but was also remarkably proficient in many European languages. His knowledge of the Scandinavian languages was freely given to many of his co-workers in science. Personally, Mr. Linell was quiet and retiring ; absorbed in his chosen field of Nature, he found little time for amusement or society. He was wholly unselfish, and gave much to others, in time, knowledge, and direct scientific work. So patient was he that the daily routine of museum work was performed with a faith fulness rarely equalled. The posthumous paper printed below includes all of the un published descriptions left by Mr. Linell and which were found OF WASHINGTON. 179 upon his desk after his unfortunate and sudden demise. The last description, that of Hyporhagus texanus, was completed the Saturday preceding his death, which occurred on Monday, May 3, 1897. E. A. S. THE ENTOMOLOGICAL WRITINGS OF MARTIN L. LINELL. 1.

M., nine examples from Los Angeles County, California, collected by Mr. D. W. Coquillett. This species superficially resembles dijfficilis^ Leconte, but the latter has the apex of the prosternum simple, the thorax narrowed from the base with much narrower, deeply emarginate apex and the posterior angles longer, slightly erected and embracing the sides of the humeri. Intercalated in Dr. Horn's synoptic table, E. coquilletti takes its place next after politus, Horn, which has the hind angles of thorax still more obtuse, the sides rounded from the base and the apex nearly semicircularly emarginate. Eleodes insular is , n. sp. First joint of anterior tarsi in the male with a large dense brush of golden hairs at the apex beneath. Anterior femora with a small acute tooth in the male, obtusely angulate in the female. Elongate, black, feebly shining. Antennae robust, much longer than head and thorax. Head with a smooth space on vertex, the front and epistoma coarsely punctate. Thorax subquadrate, slightly narrower at apex than at base ; sides finely margined, broadly and evenly rounded ; anterior angles subacute, slightly prominent, posterior angles obtuse; disc moderately convex, sparsely and finely punctate. Elytra at base not broader than the base of thorax, gradually wider, widest at apical third, much broader in the female, suddenly declivous posteriorly and slightly produced at apex; disc moderately convex, slightly depressed along the suture in the female, with regular distant series of fine punctures, the intervals very sparsely and minutely punctulate. Legs long and slender, densely and strongly submuricately punctate. Anterior femora with a distinct but obtuse tooth in the male, subangulate in the female. Anterior tibiae with the spurs subequal in both sexes. Tarsi with the spines ferruginous, the first joint of the anterior pair in the male with a large dense brush of golden silky hairs at the apex beneath. Length 15 to 16 mm. Type No. 4169, U. S. N. M. Thirty-five specimens from Sta. Margarita Island, Lower California, collected by the " Albatross" Expedition of iSSS. The species resembles somewhat E. quad- ricollis, Eschscholtz, but the thorax is widest at base, and the elytra are distinctly widest beyond the middle. All the specimens are uniform in sculpture, without any tendency to muricate punctuation. The unique sexual characters of the male require a new subgenus between the Eleodes proper and Blapylis. Coelocnemis rugosa, n. sp. Elongate, deep black, feebly shining : Thorax very convex, broader than long; sides not angulate, broadly rounded anteriorly, sinuate posteriorly ; hind angles rectangular ; disc densely and strongly punctate, rugose at the sides. Elytra very convex, oval, widest beyond the middle, abruptly declivous posteriorly, the apex oval, not acuminate; disc densely punctate and transversely rugose, the serial 182 ENTOMOLOGICAL SOCIETY punctures somewhat larger and deeper. Ventral surface moderately punctate, prosternum and base of ventral segments rugose. Femora rugosely punctate, the posterior ones reaching the apex of elytra. Length 19 mm. Type No. 4170, U. S. N". M. Two examples, from Los Angeles County, California, collected by Mr, D. W. Coquillett. The species resembles in form C. dilaticollis, Mannerheim, but is abundantly different by the thorax and elytra being strongly convex and rugose. Conibius rotundtcollts, n. sp. Robust, oblong, convex, smooth, piceous, black, feebly shining. Head transverse, prominent at the sides before the eyes, strongly punctate; epistoma broadly emarginate ; antennae very robust, shorter than thorax, slightly incrassate to apex, third joint a little longer than fourth. Thorax one-half broader than long; apex truncate with the angles obtuse, sides scarcely depressed, strongly rounded, with a fine reflexed margin, not fimbriate, posteriorly arcuate, without angles; base broadly, feebly rounded ; disc rather finely and sparsely, at the sides more coarsely and densely punctate, with a smooth median line. Elytra ovate, widest one-fourth from the base; humeri margined, obtusely rounded; surface distinctly alutaceous, with regular series of fine punc tures, intervals entirely flat, with still finer irregularly scattered punctures. Epipleura; broad, smooth. Abdomen polished, sparsely and finely punc- tulate. Legs robust. Anterior tibiae strongly and gradually widened to apex, convex above, flattened beneath, the outer apical angle slightly obtuse, not at all rounded, the outer edge and hind surface denticulate. Tarsi short, slender. Length 4 mm. Type No. 4171, U. S. N. M. One example from San Diego, Texas, collected (April 29, 1895) by Mr. E. A. Schwarz. This specimen is nearest allied to Notibius gagates Horn, which is placed in the genus Conibius by Capt. Casey, but the dilated anterior tibiae and rounded thorax will require a new subgenus according to his arrangement. Ancedus texanus, n. sp. Elongate oval, depressed, ferruginous, darker above, sparsely clothed with rather long erect hairs. Antennae slender, second joint short, third equal to fourth, last joint but slightly longer and wider than the preceding one. Eyes large, separated by a little more than their own width, viewed from above. Front very coarsely punctate at the sides, smooth along the median line. Thorax twice as broad as long, as wide as elytra at base, apex truncate with rounded angles ; sides strongly rounded, subangulate at middle, sinuate behind, the margin feebly re- flexed ; base broadly rounded at middle, feebly sinuate near the sides with an impressed smooth fovea in front of the sinuation; hind angles rectan gular, not prominent; disc feebly convex, very coarsely rather densely punctate, the intervals polished. Elytra feebly shining, densely punctate, OF WASHINGTON. 183 the punctures much smaller than those of thorax, with traces of smooth intervals on the disc. Ventral surface and femora shining, sparsely and finely punctulate. Tibiae straight, slender. Tarsi slender. Length 7.5 mm. Type No. 4172, U. S. N. M. One example from Brownsville, Texas, collected (June 9) by Mr. E. A. Schwarz. The species differs from A. brunneus by its much larger size, the long third antennal joint (in brunneus scarcely longer than the second) and the wider thorax with less acute hind angles. It is also very distinct from all the Mexican species, described by Champion. Platydema inquilimim, n. sp. Regularly elliptical, moderately convex, entirely ferruginous, somewhat darker above, feebly shining. Prosternum arcuate between the coxae, deflexed behind. Clypeus as long as two-thirds the distance between the eyes in front, separated by a shallow impression, which is transverse to near the eye, then angularly deflexed to the broadly rounded side margin of the head ; front margin as broad as the distance be tween the eyes ; surface convex, finely obsoletely punctulate. Front feebly convex, more strongly and densely punctate. Antennae gradually thick ened, subserrate, sparsely pubescent. Thorax relatively very long, evenly convex; sides broadly rounded and convergent from the base, margin narrowly reflexed ; posterior angles acutely prolonged, anterior angle rect angular with rounded apex; base strongly bisinuate, distinctly margined the whole length; basal impressions punctiform ; disc finely punctate, densely at the sides, more sparsely at the middle and obsoletely on the basal lobe. Scutellum broader than long, acute at apex, sparsely punctu late. Elytra with striae of close-set fine punctures, the striae not at all im pressed on the basal half but deeply so toward apex; intervals flat, con vex at apex, sparsely, still more finely punctulate. Ventral surface finely punctate. Legs finely pubescent and punctulate. Length 4 mm. Type No. 4173, U. S. N. M. Four examples, collected near Tucson, Arizona (Dec. 23) in nests of a wood rat {Neotoma albigula} by Mr. H. G. Hubbard. One example kindly presented to the National collection by Messrs. Hubbard and Schwarz. Branchus opatroides Champion occurs in southern Texas. It is very much smaller than B '. Jloridanus. Genus Pyanisia Laporte de Castelnau, Hist. Nat. Ins. Col., II, 1840, p. 235. This genus is the only representative in the New World of the tribe Amarygamides, which differs from Meracanthides by the unarmed femora and the long metasternum*. Two species have been found within the United States, P. opaca, Solier, and P. tristis, Castelnau. The former has the base of the thorax broadly rounded, the latter strongly bisinuate. P. tristis 184 ENTOMOLOGICAL SOCIETY was collected at Brownsville, Texas, by Prof. C. H. T. Town- send. CISTELID^E. Genus Charisius Champion. (Biol. Cent.-Amer. Ins. Coleopt, vol. IV, Pt. i, p. 421). A genus of Cistelidae having the an terior and intermediate tarsi with the third and fourth joints and the posterior with penultimate joint broadly lobed, prosternum obliquely sloping in front, body glabrous, winged, thorax narrow with a transverse basal groove, mandible slightly bifid. It should take its place in our list between Allecula and Hymenorus. isius floridanus, n. sp. Elongate, subparallel, convex, shining reddish brown. Head rather sparsely, somewhat coarsely punctate.

Male : anterior tibiae simple, anterior tarsi with basal joints lobed; fifth ventral segment flattened. Last ventral seginent with the lateral lobes curved and spoon-shaped, the central sheath curved and with rounded apical margin. Length 7 mm. One example from Cocoanut Grove, Fla. Type No. 4174, U. S N. M. Very closely allied to C. inter stitialis^ Champion, from Jalapa, Mexico, but the male has not the central sheath of the last ventral acuminate as in that species. MONOMMID^E.

Length 5 to 6 mm. Six examples collected in decaying Opuntia cngelmanni at San Diego, Texas, by Mr. E. A. Scbwarz. Type No. 4175, U. S. N. M. This species is easily distinguishable from the previously de scribed species by the very short thorax with arcuate sides, the carinate lateral striaB and the sexual characters. Under the head of " Short Notes and Exhibition of Speci mens," Mr. Fernow referred to the recent increase of pin-holes in timber from the Southern States. The insect producing the damage is probably some Ptinid beetle, but there is a possibility that it may be a Scolytid. He expressed the hope that it would prove to be the latter, since then its ravages may be met. If it turns out t be a Ptinid, however, there is little hope of a remedy unless it should be ascertained that deadening the trees at another season than that now employed will prove efficacious in preventing dam age. He pointed out the interesting fact that the rapidly growing interest in forest management in the United States will, no doubt, afford careers for future economic entomologists. Mr. Schwarz stated that pin-holes, so called, are caused either by Ptinids or by inside feeding Scolytids, and spoke somewhat at length on the habits of these groups. He showed further that damage by beetles of the genus Lyctus is becoming vastly more common than it was even a few years ago, and that he is at a loss to account for this increase, unless there has been some change in the method of drying timber. Dr. Smith showed Beijerinck's recently published paper on the " Cecidio-genesis and alternation of genera of Cynips calrcis" and briefly reviewed the work. Apropos to this paper, Mr. Ash mead recalled the fact that alter nation of generations had already been established in this country in the case of a species of the genus Callirhytis, namely, by Dr. Riley with'C. operator.* Mr. Fernow referred to the fact that * Vide Science, 1895, p. 6, reprint, April 26. 186 ENTOMOLOGICAL SOCIETY Cynips calicis occurred originally only in the Mediterranean re gion, and queried how it could have reached the Netherlands. He was answered simultaneously by Messrs. Schwarz and Howard that it was obviously a commercial importation in the galls. Mr. Ash mead referred to the fact that European Cynipids do not attack the imported American oaks in the Kew Gardens, London. Mr. Schwarz exhibited specimens of Phodago alticeps Lee., hitherto considered a rather rare blister beetle, but which has been found by Mr. Hubbard to be extremely common in the desert region along the Gila River. He read the following extract from a letter received from Mr. Hubbard and dated Tucson, Ar., April 15, 1897: HABITS OF PHODAGA ALTICEPS LEG. By H. G. HUBBARD. . . . Over the burning sand on the low hills at Tacna on the lower Gila River there ran from time to time specimens of a strange black Meloid, Phodaga alticeps. This insect is most remarkable in its habits. It does not fly at all, although the wings are large and well developed and the wing-cases are as thin as tissue paper. The creature has long legs and runs about actively visiting the scattered patches of small flowering plants and sucking the nectar from such of the flowers as it can reach without leaving the ground. When pursued the beetle raises at once its thin and concave elytra and spreads its transparent under- wings and speeds away like a little ship with black sails set wing and wing. I thought at first that it did this to assist its long legs in getting over the ground more rapidly by the aid of the wind, but I found that the real object is to uncover some bright orange- colored scent glands at each abdominal joint. These scent glands it has the power of protruding or concealing at will, exactly as in the Malachiidas. The living insects when captured thus have the uncovered abdomen brightly maculate with orange at each suture along the sides. But when dead these spots entirely disappear and the abdomen becomes uniformly black again. I gathered a large series of this species although it was hot work chasing them over the burning hillside at a temperature of 120 at noonday. They were not very alert, however, and were not difficult to capture, as they seem to rely upon the pro tection of their scent glands. I did not perceive any strong odor and suppose it is rather a repellant taste on which they rely. I found them only on this one hillside on the north of the Gila OF WASHINGTON. 187 River, although I saw a few on the desert mesa, between the river and the railroad station at Tacna. Mr. Howard said that the orange color shown in this way was plainly a warning color, indicating the nauseous character of the insect, to which Mr. Schwarz replied that he had seen seventeen Meloid beetles taken from a single bird stomach, which was sub mitted to him some time since by Dr. Merriam. Mr. Ashmead considered that the red markings might, in reality, be protective in connection with the character of the surroundings. - Mr. Schwarz exhibited and remarked upon two species of Coleoptera recently discovered by Mr. H. G. Hubbard in the southwestern portion of the United States, and which represent two genera new to our fauna. The first is Cylidrella moll is Sharp, an extremely slender form of the family Trogositidae (allied to Nemosoma) which was bred at Washington, D. C.,from apiece of solid wood of Parkinsonia torreyana and which was infested by an undescribed Scolytid (Hylocorus parkinsonice Schwarz, MS.). There can be no doubt that the Cylidrella is parasitic on this Scolytid. Several specimens were bred from the Parkinsonia wood which was cut out by Mr. Hubbard from a tree in the Indian reservation at Yuma, Arizona, and although not one of the speci mens agrees in coloration with the unique type described by Dr. Sharp from Guatemala, there is very little doubt about the specific identity. The second species is a Latheticus (family Tenebrion- idae, tribe Ulomini), undoubtedly distinct from the only known spe cies of this genus, L. or y zee Waterhouse, which has been found in rice brought to England from India. This new species was found by Mr. Hubbard under burned bark of the Mesquite (Prosopis juliflora} at Indio in the Colorado desert of southeastern Califor nia. The occurrence of a second species of this genus at a locality so remote from the original habitat of the type species is certainly remarkable. In discussion, Mr. Ashmead asked as to our previous knowledge of the habits of Cylidrella. Mr. Schwarz replied that the Biolo- gia Centrali Americana, in which the genus was described, is not exceeded by any other work in the paucity of statements regarding habits of the insects. He considered the name " Biologia " a 188 ENTOMOLOGICAL SOCIETY misnomer. Mr. Pratt remarked that the collectors for Messrs. Godman and Salvin had no time to study habits, since they were told simply to collect as much material as possible. Mr. Banks presented the following paper : SOME SPIDERS FROM NORTHERN LOUISIANA. By NATHAN BANKS. During the summer of 1891 I gathered a small collection of spiders from the vicinity of Shreveport, Louisiana. Although there are few peculiar or strange species in the collection, still it is of some interest, as so little is at present known of the distribu tion of our spiders. Yet there are several uncommon species, at least uncommon to one acquainted chiefly with more northern forms. Such are the Prodidomus rufus, Tetragonophthalma dubia, Acartauchcnius texana, and Thargalia aurata. Two species quite rare in the North are Histiagonia rostrata and Ballus youngi. About 127 species are recorded in this list, distributed in twenty-one families. The collection is representative of the southern Mississippi Valley fauna. This differs from the South Atlantic fauna in having some southwestern species. Seven species appear to be nsw and are here described ; a few others, principally in the Lycosidse, may prove to be new when the southern forms of this family are better known. THERAPHOSID^E.

Several specimens from Shreveport, La., Holly Springs, Miss., and Brazos Co., Texas. Mr. Ashmead asked as to the comparative richness of the spider fauna of that region. Mr. Banks replied in general terms show ing that the Attidae, for example, are more numerous in species in the south than in the north. He believes that 400 species could be collected in time in such a locality as Shreveport. He had collected 300 species in the vicinity of Ithaca, N. Y., but in northern localities there are many of the minute rock-inhabiting forms which are absent in the south. Mr. Schwarz spoke of the inequality in faunistic value of dif ferent groups of insects, instancing especially the comparatively slight value which the order Diptera seems to possess in this re spect, and asked Mr. Banks' opinion of the value of the spiders. Mr. Banks replied that, in his opinion, the spiders are one of the best groups for the study of geographical distribution. They are wingless and cannot pass natural barriers. He spoke in gen eral of the geographical distribution of the spiders of the United States, showing that the regions mapped by Dr. Merriam are, in the main, substantiated by this group. Mr. Ashmead said that while theoretically the spiders should be definitely restricted in distribution, practically he knew of so many wide-spread species that he doubted the very great faunistic value of the group. He referred to the possibility of the gossamer spiders being carried for very long distances by the wind, and Mr. Schwarz also stated that spiders are especially apt to be distributed by the hand ot man. Mr. Schwarz further said that on his return to Washing ton from Texas various spiders were found in his trunk, and asked 194 ENTOMOLOGICAL SOCIETY Mr. Banks whether these were Texas species and would intro duce a new element into the spider fauna of the District of Co lumbia. Mr. Banks replied that they were probably species which were already wide-spread, since this is the case with nearly all species of spiders which inhabit houses. Dr. Gill spoke at length on the subject of the relative value of different groups of animals from the faunistic standpoint. He showed that we must consider the problem not only from the morphological but also from the paleontological standpoint and illustrated this point in a somewhat detailed consideration of some of the striking features of the vertebrate faunas of South America. Africa and India, deducing from this consideration the conclusion that the primitive faunas of South America and Africa were de rived from the same common source, while the forms common to or similar to each other in Africa and India were derived from a common source at a later period. This means that South Amer ica and Africa were connected at an early period and that the connection between Africa and India was made at a comparatively recent date. He contended that the fresh-water fishes are the best group for the study of questions of geographical distribution, largely on account of their necessary restriction to the bodies of water which they inhabit. He showed that while the mollusks in particular, and also the insects, have changed comparatively little since relatively early geological times, the mammals have changed very greatly and the fishes occupy in this respect a posi tion intermediate between the mollusks and insects on the one hand and mammals on the other. Mr. Banks stated, that, in his opinion, water forms are not as good as land forms for the study of geographical distribution ; at all events this is the case with aquatic insects and arachnids. Fishes are bv no means so limited in their distribution as land forms. Mr. Marlatt spoke of the extraordinary distribution of Bryobia pratensis, which occurs from New England to California, and is known in the mountains of Montana at an elevation of 7,000 or S,ooo feet, remote from civilization, and also in the Southern States. What is probably the same species also occurs in Europe and in Australia. He considered this one of the most extraordi- narv instances of distribution known. Mr. Banks thought that OF WASHINGTON. 195 this species was simply an ordinary cosmopolite and showed that a number of other mites which he especially mentioned are also practically cosmopolitan. Mr. Howard called attention to the fact that this clover mite is peculiarly adapted to a commercial distribution. It may and probably has been carried commercially on nursery stock all over the world, while from the habits of the adults in crawling great distances in search of hibernating quar ters it may be carried on anything coming from the household, or even upon the bodies of animals. Mr. Marlatt said that the occurrence of this insect upon cultivated trees and in households had only recently been recognized, and that its wide distribution was probably of very early occurrence. Mr. Schwarz stated that the occurrence of this Bryobia on very high mountains is very re markable. Mr. Hubbard and himself have found it during the month of June in the Wasatch Mountains of Utah, at an eleva tion of from 10,000 to 1 1 ,000 feet. The eggs occurred in such quantities under stones between the snow fields that they could be scraped up by quarts. The next paper, which was presented by Mr. Schwarz, was entitled : NOTE ON THE CEDRELA PSYLLIDS (GENUS FREYSUILA ALEMAN). By E. A. SCHWARZ. Many years ago, the late Dr. Eugene Duges, of Guanajuato, Mex., sent to the lamented Dr. C. V. Riley some badly pre served specimens of a remarkable Psyllid, with the statement that this insect was greatly injurious to Cedrela trees.* They were then considered as belonging to an undescribed genus and species. What appears to be the same species was sent some years later by Dr. A. Ernst, from Caracas, Venezuela, and by Mr. F. W. Urich, from the island of Trinidad, W. I., the species being in either case marked as being injurious to Cedrela trees. Finally, in 1896, Dr. Alfred Duges, of Guanajuato, Mex., forwarded ad ditional specimens to Dr. L. O. Howard, with the statement that this Psyllid had been described by Dr. J. Aleman, under the name of Frey-Suila dugesii. * Cedrela belongs to the family Sterculiaceae. The wood of C. odorata (and perhaps also of other species of the same genus) has of late years ac quired considerable economic importance, and it is stated that it is never attacked by any insect, not even the termites, 196 ENTOMOLOGICAL SOCIETY Dr. Aleman's account and descriptions extend over several pages in La Naturaleza, but are far from being satisfactory. In his descriptions he gives only characters common to all Psyllids, but the genus is recognizable from the rough figures. I give herewith a more detailed description of this remarkable genus, for which the name proposed by Aleman has to be re tained with a slight change. GENUS FREYSUILA ALEMAN. Frey-Suila Aleman, La Naturaleza (2) i, No. i, 1887, pp. 21-26, tab. III. Body robust. Vertex transverse, broadly excavated longitudinally along the median line, its front margin triangularly notched at middle, greatly elevated and obliquely truncate on each side of the excision ; eyes large, prominent, the tempora well developed behind them; anterior ocellus not visible from above ; frontal processes absent and represented on the under side of the head by a protuberance on each side beneath the antennal base and in front of the large knob-shaped clypeus. Antennae unusuallj' long; first two joints short and thick as usual, third joint extremely long, much wider than the following joints, densely asperate and densely pubescent, slightly tapering at apical portion, joints 4 and the following very thin and slender. Pronotum and dorsulum greatly ascending posteriorly, the former slightly emarginate behind, lateral impressions shallow and confluent ; dorsulum transverse, anterior margin hardly less convex than the posterior margin. Elytra hyaline, membranaceous, elongate-oval, gently widening from base to apical third, apex broadly and regularly rounded: cubitus as long as, or slightly shorter than, discoidal part of subcosta ; a distinct ptero- stigma, stem of second fork not parallel with radius; tip of wing at the termination of the 4th furcal or close to it within the second marginal cell ; legs extremely long and slender, tibiae not dentate at base, tarsi normal ; genital plate of male without lateral appendage, genital segment of female short. The genus is readily known by the form of the antennae and the very long legs. The front margin of the head recalls that of Homotoma (Psyllinae) and Rhinopsylla (Triozinas), but in both of these genera the vertex is more or less flattened. Freysuila is difficult to place in Dr. Fr. Loew's arrangement of the subfamilies of Psyllidae, but if we adopt his system the genus can only be placed among the Aphalarinae. However, this subfamily is very badly defined, and is either not separable from the Psyllinae, or an entirely new arrangement of the genera has to take place. At any rate the genus differs from all genera placed among the Apha larinae by the great length and slenderness of the antennae and the remarkable development of the third antennal joint. OF WASHINGTON. 197 The type of the genus is F. dugesii Ale man described from Guanajuato, Mexico ; two other forms, which are either strongly marked varieties, or closely allied species, are known from Caracas, Venezuela, and Trinidad, West Indies. These three forms may be distinguished as follows : Third antennal joint at most twice the length of the fourth, either entirely ochreous or pale only at base. Head and thorax without definite black markings. Third antennal joint almost twice as long as the fourth; fore-wings narrower, more narrowly rounded at apex; fourth furcal running into the tip of the wing (Guanajuato, Mex.) dugesii Aleman. Third antennal joint only one-third longer than the fourth ; fore- wings wider, broadly rounded at apex ; tip of wing within the 2d marginal cell (Caracas, Venezuela) var. ernstii Schwarz. Third antennal joint at least two and one-half times longer than the fourth. Head and thorax with well defined black markings ; fore-wings broadly rounded at apex: fourth furcal running into the tip of the wing; third antennal joint black (Trinidad, West Indies) var. cedrelce Schwarz. In discussing this paper Mr. Ashmead stated that the very re markable antennas of Freysuila, which resembled in fact those of the saw-fly genus Xyela, would warrant the erection by Mr. Schwarz of at least a new tribe. Some discussion ensued between Messrs. Gill, Ashmead, and Schwarz as to the advisability of forcing a form like this into the dichotomous table in preference to putting it aside and forming a new group. The discussion took a general turn, and Messrs. Gill and Ashmead favored the last view and Mr. Schwarz the former. JUNE 17, 1897. President Marlatt in the chair and Messrs. Gill, Benton, Motter, Pratt, Waite, Chittenden, Ashmead, Schwarz, Patten, Howard, Heidemann, Fernow, Hine, and Matthis also present. Mr. Schwarz exhibited specimens of a probable new species of the genus Telegeusis Horn (family Drilida?) , collected by Mr. Hub- bard at the Hot Springs (southwestern foot of Galiuro Mts.), Arizona, and spoke at some length of the remarkable palpi pos sessed by this genus. Mr. Ashmead asked why the palpi in certain genera in many groups are so prolonged. He noted a 198 ENTOMOLOGICAL SOCIETY new genus of Braconidae, which he had recently discovered, which possessed very long palpi. Such genera seemed to occur in special number in certain regions of the West, and he instanced several which he had seen from Colorado. Mr. Schwarz replied that in Telegeusis the character occurs most probably only in the ale, and that these long palpi have a sensitive function. The male is unknown, and probably larviform. The modification of < ,e terminal joint of the palpi into a long organ occurs in many f enera, and is difficult to explain. Mr. Marlatt, apropos to the remark made by Mr. Ash- mead at the last meeting concerning the absence of oak galls on the American oaks in the Kew Gardens, stated that it would be interesting to know whether galls occur on the European oaks in these same gardens, and that, as a matter of fact, galls are rare in arboretum s or cultivated grounds, in stancing the oak group on the grounds of the Department of Agriculture. Wherever the ground is cared for and the leaves carefully raked up and burned, oak galls will be scarce or ab sent. Mr. Ashmead said that he had found oak galls on the Smith sonian Grounds, and Mr. Marlatt replied that the Smithsonian Grounds are not so thoroughly cared for as those of the Depart ment of Agriculture. Mr. Waite remarked that among the oaks in the Department of Agriculture there are very few native trees. Mr. Howard presented a paper, of which the following is an abstract : v A DIPTEROUS PARASITE OF LACHNOSTERNA. By L. O. HOWARD. (Author's abstract.) The speaker exhibited two specimens of a Lachnosterna of the fusca group ; one bore upon the thorax two groups of Dipterous eggs, one group consisting of five oval eggs laid side by side to the right of the median line, and the other group consisting of four similar eggs, similarly placed, to the left of the median line. The other specimen bore a cluster of seven such eggs to the left of the median line. Each of these eggs was about i mm. long, and of a light yellow-brown color. He had never seen similar eggs upon a Lachnosterna, nor had his associates, Messrs. Schwarz and Pergande, out of many thousands of specimens ex- OF WASHINGTON. 199 amined. The two specimens in question were collected June 4th, near Tannersville, New York, at an elevation of 2,500 feet. He referred to a note by Dr. Lugger, on page 50, volume I of the Proceedings of the Society, which recorded the oviposition of a Tachina fly upon the hard body of Rhodobcemts ij-punctatus, a bright-colored beetle which Dr. Lugger thought had been mis taken for a caterpillar by the Tachina fly. He also referred to the rearing of a fly of the genus Sarcophaga from a Carabid beetle, Scariies subterrancus, by Mr. Chittenden, as noted at a recent meeting of the Society. He further stated that, on one occasion, a Tachinid had been reared at Washington from Lach- nosterna inversa, specimens of which had been placed in a box to get the eggs. The notes do not prove the parasitism, which was, however, strongly suspected. Two cases are also recorded in the notes in which Tachina flies have been bred from Lach- nosterna larvae. The case possesses interest not only on account of its rarity, but on account of the fact that all of the Lachnosternas hide be neath the surface of the ground during the day, whereas the Tachina flies are exclusively day-flyers. Mr. Coquillett thinks that the eggs, from their color, may not be those of a Tachinid, but the speaker did not know what other insect to suspect. Mr. Schwarz suggested that the peculiar fact brought out by Mr. Howard that the Tachina flies are day-fliers and the Lach nosternas night-fliers, might be modified since there is always a possibility that we may have night-flying Tachinids or day-flying Lachnosternas. Moreover, on account of the stony ground and comparative absence of soil in the locality where these specimens were collected, the beetles might not have been able to enter the ground during the day and were thus exposed to the attacks of Tachina flies ; further, since Tachinids have been reared from Lachnosterna larvae, and since these larvas are always found at a considerable distance below the surface of the ground, may not the beetles carry the eggs to the vicinity of the larvas ? Further he had noticed that the beetles when hiding by day under leaves, etc , often assume an erect position, so that if any portion of the body were exposed, or nearly exposed, it would be the head and thorax. He emphasized the unusual character of the observation by showing that he had collected adult Lachnosternas by the quart during one season and had never seen such specimens as those exhibited by Mr. Howard. Mr. Ashmead presented the following paper : 200 ENTOMOLOGICAL SOCIETY ON THE GENERA OF THE CLEONYMID^E. By WILLIAM H. ASHMEAD. The Cleonymidce were first separated as a family by Francis Walker, in 1837? kilt ne did not properly define the family or really appreciate the structural characters that separate it from allied groups, since of the ten genera recognized by him as be longing to it, he included no less than five genera which belong to the Encyrtidas (Eupelminae and Encyrtinaa) , and one of these, Macroneura Walker, was based upon a male Eupelmus. Still later, or in 1856, Dr. Arnold Forster recognized this family under the name Cleonymoidce and defines five new genera, viz., Tricoryphus, Heydenia, Plutothrix, and Tetracampe. Forster correctly excluded from the family Stenocera Walker, Calosoter Walker, and Ericydnus Haliday, but included three other genera not included by Walker, namely, Trigonoderus Westw., Platynocheilus W'estw., and Merostenus Walk. Tricoryphus Forster is, as I have already shown, the wingless female of Cerocephalus Westw., and it, as well as Plutothrix, Tetracampe, and Platynocheilus, does not belong to the family, the first named belonging to the S-palangiina, the others to the Entedonidfe. The family Cleonymidce, as now restricted, may be readily distinguished by the large triangular mesepisternum, by having either the anterior or posterior femora much swollen and some times toothed, or both are swollen, with the hind femora dentate or toothed beneath ; if the legs are slender, the hind pair are very long, their coxae long, cylindrical, while the radius in the front wing is very short and the postmarginal is very long, ex tending to the apex of w r ing (Pelecinelld}. The family comes very close to the Encyrtidce, and especially to the subfamily Eupelmince, but the species may always be dis tinguished from any in this family by the absence of a movable or saltatorial middle tibial spur, the impressed mesopleura, the non- impressed mesonotum, and usually by the much longer marginal vein. I have recognized four subfamilies, but one of these, the Colo- trechnince, is, how r ever, provisional or supposititious, since it is based upon Thomson's genus Colotrechnus, which is unknown ,to me, and may or may not belong here. The following tables will aid the student in recognizing the subfamilies and genera : OF WASHINGTON. 201 FAMILY LXVI. CLEONYMID^E. TABLE OF SUBFAMILIES.

This subfamily is represented by a single genus, Pelecinella Westwood, readily recognized by the characters given in my table of the subfamilies. See also my paper entitled " On the genus Pelecinella Westwood, and its position among the Chalcididae." Proc. Wash. Ent. Soc., vol. iii, pp. 230-233. SUBFAMILY IV. COLOTRECHNIN^E. This is likewise based upon a single genus, Colotrcchnus Thomson. It is unknown to me in nature, but evidently from Thomson's description belongs in this family. Apropos to Mr. Ashmead's paper, Mr. Marlatt spoke of the danger of using published descriptions only as bases for synoptic work on account of the frequent omission of important characters in published descriptions. Mr. Howard made some remarks on the discovery of Eu- proctis chrysorrhcea in the vicinity of Boston, which were sup plemented in discussion by Mr. Marlatt, who had just returned from Boston, and was able to give details as to the work which had been done against the insect, and as to the measures adopted by the State legislature. The paper was further discussed by Messrs. Schwarz and Matthis, OF WASHINGTON. 207 Mr. Schwarz remarked that it is wonderful that this species, as well as many other European insects, have not been introduced into America at an earlier date, and called attention to the fact that, as already pointed out by Osten-Sacken, the most unexpected in troductions frequently occur, whereas those most to be expected may not be brought about for many years. He stated that this insect is one which is especially guarded against by police regu lations in Germany, the inhabitants of a given district being noti fied on a certain day to destroy the larvae upon their premises, and the police immediately thereafter inspecting the work and fining delinquents. Mr. Matthis spoke of the special clanger from this imported species. He said that it is one of the forms whose egg- masses are distasteful to birds through the admixture of hairs from the anal tuft of the female moth. For this reason birds will not touch it. He recounted his European experience with the species, and both he and Mr. wSchwarz stated that the female flies well, and that the species may therefore spread in the adult stage. OMISSION FROM PROCEEDINGS OF MAY 13, 1897. The publication committee announces that through an unfortu nate error no mention is made in the proceedings of the meeting of May 13, 1897, of the reading of an elaborate paper on the Genera of the Encyrtinas by Mr. Ashmead. This paper has been withdrawn for publication elsewhere. Mr. Howard read a paper, of which he has submitted the fol lowing abstract : THE THOMSON-MAYR PRIORITY QUESTION SETTLED. By L. O. HOWARD. It will be remembered that, at the last meeting of the Society, following the reading of the paper on the genera of the Encyr- tina3, by Mr. Ashmead, a discussion took place between Messrs. Ashmead, Schwarz, and the writer relative to the possibility that volume IV of Thomson's " Hymenoptera Skandinavias," the printed title-page of which showed the date 1875, was, in reality, published subsequently to Mayr's paper on the Encyrtinas, which was read before the Zoologisch Botanische Gesellschaft in Wien, December, 1875. It has been established since this discussion took place that Mayr's paper was published not later than the end of January, 208 ENTOMOLOGICAL SOCIETY 1876, since the receipt of the printed paper is acknowledged in one of the German periodicals published in February, 1876. It was supposed that the Thomson work might have been printed by signatures, and that while the first signature, containing the title- page, might really have been published in 1875, the later signa tures might have been published at a considerably later date. The writer had addressed a letter to Dr. Christopher Aurivillius, of Stockholm, and, on June 7th, received a reply w r hich practically settles the matter. Dr. Aurivillius writes, under date of May 1 2th, that he has gained full information on the subject through consulting Thomson's letters to Stal in the years 1875 and 1876. It appears that volume IV of the " Hymenoptera Skandinaviae " was published in two parts, Part i containing pages i to 192, and including, on pages 112 to 183, his consideration of the Encyr- tinaB, the only portion of the work about which there is a possible conflict. The first sheet, including the title-page with the date 1875, was printed in September or October, 1875. The second sheet (of 16 pages) was not printed on October nth, 1875. The impression of the following sheets, or signatures, was delayed for the very significant reason that Thomson hoped to use some ot Dalman's types of Encyrtinae, which, at that time, had been loaned to Dr. Mayr. The last sheet was printed at the end of May, or in the first days of June. It will be noticed that I have used the word " printed" up to this time. On June 6th Thom son wrote that the first part was published, and that he intended to continue the printing in August. It thus appears that Part i of volume IV of the " Hymenoptera Skandinavias " was certainly not published before the latter part of May. Mayr's work, hav ing been published the end of January, thus antedates Thomson's by four full months, and all coincident new genera should, there fore, be known by Mayr's names. These facts have never been recorded, and are even unknown to Dr. Dalla Torre, the author of the great catalogue of the Hy menoptera <>f the world, since, in a recent paper in the Wiener Entomologische Zeitung, he adopts the convenience method of deciding the priority between these two writers as regards the genera of Encyrtinas. The paper was discussed by Messrs. Schwarz, Ash mead, Gill, Waite, and Howard. Mr. Schwarz called attention to the fact that the first published announcement of the receipt of Part i, volume IV, of Thomson's Hymenoptera Scandinavian which he was able to find occurred in the Entomologische Monatsblatter of April and May, 1877. Mr. Ashmead expressed his pleasure at the settling of the long OF WASHINGTON. 209 disputed question, and spoke at some length on the importance of exact dates being printed on editions of author's extras, a mat ter which was further discussed by the other members men tioned. ,/3^ OCTOBER i/fTH, 1897. Vice-President Gill in the chair, and Messrs. Ashmead, Banks, Schwarz, Fernow, Patten, Dyar, Fairchild, de Schweinitz. Swingle, Busck, Pratt, Motter, Benton, and Howard also present. The following new members were elected : Corresponding A. L. Quaintance, Lake City, Fla., and J. S. Hine, Columbus, Ohio. Active Harrison G. Dyar. Under the head of 4t Short Notes and Exhibition of Specimens," Mr. Schwarz spoke of the collection of insects recently made by Henry G. Hubbard in southern Arizona. This collection is altogether the most extensive and valuable which has been made in that part of the country. In Coleoptera alone he estimates that there are between 300 and 400 species new to the fauna of the United States. He spoke at some length about the previous collections, by Drs. LeConte and Horn, by the Government sur veys, by Morrison, and by Wickham. Morrison's sets, when sent abroad, were usually labelled " Sonora," and have thus been included in the Biologia-Ccntrali Americana. When sent to American workers, however, they are labelled u Arizona." They were probably all made, however, in the Graham Mountains, near Ft. Grant, and above Ft. Huachuca. Mr. Schwarz exhibited a specimen of the Scarabaeid Lissome- las fiohri Bates, a genus new to the United States, and allied to Cremastochilus. The specimens collected by Mr. Hubbard at Ft. Grant, Ar., however, were not found in ants' nests, but under old leaves, nor could any traces be found of thoracic glands, which are supposed to be attractive to ants. He spoke of the velvet-like coating on the rear half of the elytra, and said that in the speci mens collected it was badly scratched, possibly by ants. He further generalized as to the Arizona fauna, stating that we do not know its Mexican limits, and remarked upon the great varia tion between the faunas of the valleys and of the mountains. Mr. Fernow thought that this great difference was due entirely 210 ENTOMOLOGICAL SOCIETY to moisture changes. In Arizona, wherever an elevation of 5,000 feet is reached, there is rainfall and forests which are lack ing at a lower elevation. Dr. Gill stated that the segregation of the Coleopterous fauna of California had been remarked upon 40 years ago by LeConte. Mr. Schwarz stated that LeConte did not go into the mountains of Arizona, and, in fact, failed to realize the difference between the California and Arizona faunas, because he was there in the winter-time. It is high time to explore southern Arizona from a biological standpoint, since cattle are fast doing away with the vegetation of the valleys and the moun tain canyons, which will soon become deserts. In this statement he was supported by Mr. Fernow, and some further discussion ensued between Messrs. Fernow and Schwarz as to the character of the vegetation of Arizona, and its influence upon insect life. Mr. Ash mead confirmed Mr. Schwarz's statement as to the great richness and value of the collections made by Mr. Hubbard in southern Arizona. Mr. Banks exhibited specimens of Chrysopa ypsilon, each of which carried a minute Cecidomyiid fly on its wings. The specimens were collected by Mrs. Slosson in the White Moun tains, and she states that it is a common habit. Mr. Banks stated that the Cecidomyiids were taking advantage of the Chrysopa to carry them from place to place ; that they probably in this way were carried to colonies of plant-lice upon which their larvas might feed. Mr. Ashmead spoke gf a parasitic wingless fly of the family Borboridae living upon a snail which had been collected by Mr. Cook in Liberia. He agreed with Mr. Banks's conclu sions. Mr. Schwarz suggested that possibly the Cecidomyiids might have become entangled upon the wings of the Chrysopas, and were thus trapped and unable to get a way. Mr. Banks, however, said that he had been informed by Mrs. Slosson that nearly all of the flies fell oft' when the Chrysopas were captured, and that, therefore, they cannot be entrapped. The first paper of the evening was presented by Mr. Ash- mead, entitled "A new Cynipid Genus from Africa."* In answer to questions by Mr. Schwarz, Mr. Ashmead stated *After the presentation of this paper, Mr. Ashmead discovered that this new genus was identical with Oberthiirella Saussure, and has withdrawn his description. OF WASHINGTON. 211 that there are no true gall-making Cynipids known in tropical Africa. The genus Rhoophilus has been described from Africa, but, in his opinion, this may not be a gall-making form. Mr. Howard, in view of the fact that several persons who had visited the tropics were present at the meeting, inquired as to the abundance of plant-lice in tropical regions, and w r as an swered by Messrs. Fairchild and Ashmead, that they seemed to be much less abundant than in temperate regions. A short paper w r as read by Mr. Howard, entitled *' Notes on the House-fly."* In discussing this paper, Mr. Ashmead suggested the trial of chloride of lime, which is commonly used in the Southern States as a disinfectant and for sprinkling on garbage of various sorts. Mr. Schwarz, apropos to the statement as to the desirability of killing the early flies, stated that, in his opinion, there is a fallacy involved in this general recommendation regarding injurious in sects. Where a species breeds with such astonishing rapidity as does the house-fly, there is little use in killing part of the early females if others are allowed to escape. He stated that it made little difference to him whether one million of flies were bother ing him in July or two millions ! Apropos to the incidental remark in the paper about the carrying of contagion by house-flies, Mr. Fairchild spoke of the prevalence of an eye-disease in the Fiji Islands. Very many natives have lost the sight of one eye, and some of two, from this disease, which is generally considered to be carried by flies. The houses of the white inhabitants are thoroughly screened, the heads of children are protected by nets when they go out of doors, and even the natives customarily carry branches or fans in their hands to brush the flies away from their heads. Messrs. Fernow and Howard spoke of the similar carriage of the purulent conjunctivitis, prevalent in Egypt, by house-flies, and Mr. Benton spoke of his personal observations in various countries at the eastern end of the Mediterranean, confirming the opinion that the disease is carried by the house-fly. Mr. Ashmead referred to the probable spread of "sore eye" in Florida by Hippelates. * Published in Bull. 10, Div. Entom., U. S. Dept. Agr., pp. 63-65. 212 ENTOMOLOGICAL SOCIETY Mr. Fairchild, in answer to a question, stated that the Fiji eye- disease in its milder form lasts, in its acute stage, 4 or 5 days and then gradually dies away. Mr. Banks read the following paper : A NEW SPECIES OF THE GENUS HALARACHNE. By NATHAN BANKS. In 1847 P r f- Allman described a remarkable mite which he had discovered in the nares of a seal from the Irish Sea. Unable to place it in any of the then existing genera, he established for it the new genus Halarachne, and named the species H. halichceri, after the genus of seal on which it occurred. He characterized the genus as follows : " Palps free, filiform, mandibles didactyle, sternal lip bifid. Legs with last joints terminated by two hooks and an intermediate three-lobed caruncle. Body entire, elongate, subcylindrical, furnished anteriorly with a dorsal plate ; eyes none." He placed the genus in the vicinity of Dermanyssus ; a posi tion which I believe to be correct. For many years little or no attention was given the mite. However, in 1884, Nehring, a German mammalologist, obtained specimens from the same seal, and published a note upon it. He maintained that it was related to the Ixpdidae rather than to the Gamasida3, chiefly on account of its shape, general appearance, and especially the posterior position ef the stigmata. Kramer, the acarologist, saw the specimens and wrote a short article upon the mite, dealing principally with its anatomy. Haller in 1886 gave a few notes upon it. In 1889 Nehring pub lished another note upon it. Its peculiar habitat is, doubtless, the reason why so few specimens have come into the hands of acar- ologists ; and thus the genus has rarely been mentioned or treated in systematic works. A short time ago Dr. Motter brought me some examples of a mite given him by Dr. Hassall, who took them from the bron chial tubes of a seal that had died in the Zoological Park. At first I thought it related to one of Kolenati's genera of bat-mites, viz., Lepronyssus ; but soon discovered that it was a species of Halarachne, closely allied to H. halichceri. The genera erected by Kolenati in the Dermanyssida? have not been generally ac cepted, and there is much uncertainty regarding them. But the great difference in habitat, and doubtless the position of the stig mata, will separate Halarachne from all other Dermanyssidae. The breathing pore is situate just above the fourth coxa, and a line from it extends around and behind the coxa. In Derma nyssus the stigmata are a little farther forward. The mouth-parts OF WASHINGTON. 213 are, however, chelate, and of the true Gamasid type. The palpi are free, and the other characters do not depart from those of Dermanyssus sufficiently to merit notice. The shape of the dor sal plate and elongate body are rather anomalous, but not char acters of importance. 1 shall therefore consider Halarachne a genus of Dermanyssidae, not greatly.differing from the other mem bers of that family ; but showing certain adaptive characters that fit it for its peculiar surroundings. Our species appears to be different from the European form ; and I describe it as follows : FIG 15. Halarachne ajnericana. : a, sternum of male ; b, stig mata and coxae ; c, mandible; all enlarged. (Original.) Halarachne americana, n. sp. White, hard parts pale yellowish; smooth, body narrowed in front, contracted behind the fourth pair of legs, broadly rounded at tip; a dorsal shield on basal half, narrow in front, broadest before the middle, then tapering behind, but broadly rounded at tip, showing an irregular cross and some geminate spots; a small round hard spot near tip of body at the anus; legs short and stout, second pair stoutest, with a few short bristles, and two claws at tip, the terminal joint longer than the others which are subequal ; stigmata just above the fourth coxae; sternal plate truncate in front, sides nearly parallel at first, then concavely tapering to the bluntly- pointed apex. 214 ENTOMOLOGICAL SOCIETY The male (perhaps not quite adult) is smaller than the female, and the abdomen does not extend much beyond the dorsal shield, and is much narrowed behind; the sternal plate is of about the same shape as that of the female, behind it there is a transverse line from each end of which there extends back a short dark line; in the middle is an elongate pointed genital opening.

Dr. Hotter, who had seen the specimens taken from the dead seal, stated that the air-passages were swarming with the mite, which, however, did not appear to have been the cause of the death of the seal. Dr. Gill suggested that Mr. Banks might, to advantage, ex change the specific name americana to monarchi, from the genus of the seal in which it was found. He objected to americana for the reason that the host of the type species is quite as Amer ican as the host of the new species. Mr. Banks objected to adopting the name monarchi, since the genera of vertebrates no less than of arthropods are frequently changed. Mr. Ashmead read a paper entitled " On the Genera of the Xyelinae.* This was a technical paper giving the characteristics of four genera of this group belonging to the fauna of the United States and forming a distinct family Xyelidas, which he had separated from the Tenthredinidae. These genera are Xyela, * Published in Psyche, Ma}', 1898, p. 214. OF WASHINGTON. 215 Macroxyela, Megaxyela, and Manoxyela. lie stated that the larvae of the group were not known, and that he had been unable to ascertain their habits with certainty, but considered that they were probably borers. He remarked upon the fact that they are found flying in the spring and then disappear for the rest of the year. Mr. Schwarz stated that many years ago he had been attracted by the beauty of the local species, which occurs in the earliest warm days in the spring. He had found it frequently on the 22d February. It used to occur very abundantly on young pines near Washington, but these trees on being examined later in the season showed no signs of injury. NOVEMBER 4, 1897. Vice-President Gill in the chair, and Messrs. Uhler, Motter, Patten, Johnson, Banks, Schwarz, Ashmead, Heidemann, Dyar, Benton, Busck, Currie, Pratt, Howard, Cook, Fernow, and Swingle also present. Prof. Dr. K. W. von Dalla Tofre, of Innsbruck, was elected a corresponding member. Under the head of" Short Notes and Exhibition of Specimens," Mr. Ashmead showed specimens of the male of Pelecinus oly- turator, sent in by Mr. Wyeth, from Indiana, and also speci mens of the genus Proterops of Wesmael, a Braconid parasitic upon saw-flies, which is remarkable in that the middle ocellus is placed between the bases of the antennae. Mr. Schwarz spoke of the abundance of Pelecinus in Detroit during the past summer. He had noticed them flying in numbers along the streets lined with maple trees, and thought perhaps they might be parasitic upon the common maple-borer, ^Egeria acerni. Mr. Ash mead, however, had told him that it is more likely to be para sitic upon a Coleopterous borer. Mr. Ashmead stated that the species has a very wide distribution, occurring from Canada to Argentina. He thinks it to be a very ancient form allied to the Proctotrypidae, and to a group of the Proctotrypidae which is always parasitic upon Coleopterous larvae. Prof. Uhler said that this species used to be common near Baltimore, and that he had once or twice caught the male. In a low spot of ground thickly covered with an undergrowth of black alder and spice bush, 216 ENTOMOLOGICAL SOCIETY and containing oaks and maples, the insect was particularly common. Mr. Banks showed a female of Meleoma signoreti Fitch, a rare lace-winged fly which he had collected on Long Island. A new species of this genus had been sent in by Mrs. Slosson. which he had named after her. Mr. Ashmead remarked that Fitch's type of this species is in the National Museum. Prof. Uhler said that he had received specimens from Illinois. Mr. O. F. Cook exhibited specimens of Peripatus novazea- landicus from New Zealand, and two small species of Peripatus from the Bismarck Archipelago. He also exhibited a Dyscritina from Liberia. A discussion as to the zoological position of Pe ripatus ensued between Messrs. Gill and Cook. Mr. Schwarz exhibited a specimen of Cychrus mexicanus Bates, a species new to the fauna of the United States, which Mr. Hubbard had found at Cave Creek, in the Chiricahua Mountains of southern Arizona. He spoke of the habits and distribution of the genus Cychrus in the United States. Mr. Howard exhibited specimens of Trypeta acidusa Walker, which had been reared from ripe peaches by Mr. Koebele at Orizaba, Mexico. Incidentally he spoke of the Mexican dis tribution of Trypeta ludens. Mr. Johnson said that it would be important to investigate the possible shipping of peaches from Mexico to the United States in order to prevent the introduction of this new pest. Mr. Uhler said that he thought he had seen the same species in San Domingo. At the request of the Chairman, Mr. Swingle spoke briefly of an undetermined mite which he had found feeding upon the mold occurring in spots upon the bindings of books in one of the rooms of the National Museum. - Prof. Uhler exhibited a series of species of American Noto- nectas, which had been named by Mr. G. W. Kirkaldy, of Wim- bleton, England. He spoke of Mr. Kirkaldy's excellent work upon this group, and indicated some structural peculiarities of the genus and its remarkable distribution in America. One species, for example, he said, is found from Rio Janeiro to Quebec. It results from Mr. Kirkaldy's studies that we have in America nine valid species of the genus. The first paper of the evening was by Mr. Heidemann, and was entitled : OF WASHINGTON. 217 HETEROPTERA FOUND ON OX-EYE DAISY (CHRYSANTHE MUM LEUCANTHEMUM). By OTTO HEIDEMANN. It is generally known that the common ox-eye daisy ( Chrys anthemum Icucanthemunt} has a great attraction for many of our insects. The plant flowers from early May until late in July. It grows so profusely on some fields that, seen from the distance, they appear to be snow-covered. In sweeping such fields early in May, I was greatly interested in finding Leptopterna dola- brata Linn., a European species of the family Capsidae, in very great numbers, and in all stages of development. They are hardly to be detected on the plant, as the larva and pupa resemble in coloration the stem and leaf. Thus it seems probable ^^.Chrys anthemum leucanthemum, which is a native of the Old World, may be the food-plant of this common Capsid. Unfortunately I was unable to find the eggs in spite of careful research. In former years I had noticed the appearance of the insect regularly on the same plant, but never did it occur so plentifully as at this season. This common Capsid has probably two broods, because I found the young larva very early in May, and also in the month of July. After this the insect disappears in our locality. Be sides this one species, I met with other heteropterous insects on the daisies, which are either attracted by the color of the flower, or visit the same in search of prey, as I found to be the case with Triphleps insidiosus Say and Phymata fasciata Gray, both hiding between the petals of the flower. I swept quite frequently during the months of May and June, and until late in July, when the daisies began to wither. As a result of my collecting I can record the following species of Heteroptera : Neottiglossa sulcifrons Stal. Poeciloscytus basalis Rent. CEbalus pugnax Fab. Calocoris rapidus Say. Hymenarcys nervosa Say. Agalliastes suavis Reut. Trichopepla semivittata Say. Stiphrosoma stygica Say. Harmostes reflexulus Stal. Halticus uhleri Giard. Corizus lateralis Say. Episcopus ornatus Reut. Corizus nigristernum Sign. Oncotylus decolor Fall. Nysius angustatus Uhl. Apocremnus robustus Uhl.MS. Cymus angustatus Stal. Triphleps insidiosus Say. Jalysus spinosus Say. Phymata fasciata Gray. Leptopterna dolabrata Lin. Coriscus ferns Lin. Collaria oculata Reut. Coriscus punctipes Reut. Lygus pratensis Lin. Sinea diadema Fab. Oncognathus binotatus Fab. 218 ENTOMOLOGICAL SOCIETY In discussion Mr. Ashmead asked whether, besides the Euro pean Leptoterna dolabrata, any of the species listed by Mr. Heidemann were especially addicted to the plant, or whether they are accidental visitors. Mr. Heidemann replied that some of the other Capsids mentioned may possibly be found to breed on the ox-eye daisy. Prof. Uhler said that the eggs of the Cap sids are very difficult to find, so that it is frequently almost im possible to determine the breeding plant of a species. Mr. Schwarz said that, the ox-eye daisy being an introduced plant, nearly all of the insects mentioned must have other original food- plants. He referred to the European Chenopodiums introduced into this country, which afford breeding places for many of our native insects. Attention was called to the fact that the Phymata listed by Mr. Heidemann seeks yellow flowers for concealment w^hile capturing its prey. Dr. H. G. Dyar presented the following communication : SOME STRUCTURAL POINTS IN SAW-FLY LARV^. By HARRISON G. DYAR, Ph. D. The larvae of the leaf-feeding Hymenoptera are slender, cruci form insects, closely resembling in general character the larvae of the Lepidoptera. The head is round, with a single ocellus on each side, a shield-shaped, not triangular, clypeus without side pieces ; large labium and distinct antennae situated below the ocellus, higher up than in the Lepidopterous larva. The body has the same number of segments as in the Lepidoptera ; thoracic feet usually strong and more distinctly functional than the ab dominal ones. The latter are weak, without terminal retaining hooks or crotchets, and are present in varying number. There are two well-marked series ; one with abdominal feet on segments 2 to 7 and 10, the other on segments 2 to 8 and 10. In a few there are no abdominal feet. The body segments are usually marked by a series of transverse creases, forming subsegments or annulets. The primitive number seems to be three, but they may be increased by the folding off of additional annulets, usually at each end of the segment, at the incisure. The original annulets themselves are seldom divided. Below the spiracles there is a longitudinal ridge, usually divided into two portions, an upper anterior and lower posterior. The three original annulets and the subventral ridge bear a series of short setae, about three on each side on each annulet, the exact number varying. These setas are small, simple ones, often greatly reduced, seldom modified. The OF WASHINGTON. 219 only peculiar form is the large, furcate spine of some of the Blen- nocampids. These are never true warts. Occasionally there may be other fine hairs scattered over the skin. The setae are distinctly variable in number, as just stated, even in closely allied forms, and it is somewhat surprising to find them not possessed of any thing like the fixity or constancy of the primary setae of the Lep- idopterous larva. They correspond in their modifications rather to secondary hairs, and it may be stated that primary setae, as that term is understood in Lepidoptera, are not present in the larvae of Tenthredinidae. Consequently they are of much less value in the. broad lines of classification, and it is interesting to see what, at first sight, appears the same character of such differ ent value in the two groups of insects. As compared with the Lepidopterous larva, the saw-fly is much generalized. In the shape of the clypeus and position of the antennas it shows less divergence from the mature insect. The thoracic feet are pre dominant, and the abdominal ones are simply membranous pads. The hair structures are very simple. The smooth skin but rarely bears processes, which do not exceed the simple papilla in com plexity. Eversible glands, however, may be present, either ven- trally or laterally, and the skin may secrete a pruinose or long woolly coating. The coloration is of the simplest. The skin is usually transparent, and the larva receives its color from the green blood. The lines consist of the outlines of the dorsal vessel and tracheal line, supplemented by fat granules. Spots are formed by black pigment, often at the setae, but the deposition of pig ment is seldom extensive, never complicated. Mimicry of special objects other than the leaves it feeds on is rarely attempted by the larva. I have in mind two cases, one from the Nematinae, the other from the Tenthredininae (neither larva bred), where the ex crement of birds is mimicked. One or two others are somewhat brightly colored. I should like to present a classification of saw-fly larvae, based on the characters just reviewed, but my material is too scanty. When our species are better known it may be possible to do this. In the meantime I will indicate some of the differences between the different groups as seen in a few examples. HYLOTOMIN^E. Hylotoma macleayi. No feet on segment 8 ; segments divided into three annulets, each with three tubercles above the tracheal line ; a large oblique subventral ridge with many setae. NEMATIN^E. Ncmatus ribesii. No feet on segment 8 ; segments divided into three annulets, each with three tubercles, the anterior ones sometimes partly wanting; a small cluster of hairs on subventral ridge. 220 ENTOMOLOGICAL SOCIETY Hemichroa americana. Feet present on segment 8 ; segments indistinctly divided into 6 annulets, one cut off before, two behind the primitive setiferous annulets as in the Tenthredinidae. On larval characters, this species clearly does not belong to the Nematinae. CIMBICIN^E. The characters are, in general, as in the Tenthredininae. I cannot give details at the moment of writing. Acordulccfadorsalis. No feet on segment 8 ; segments divided into three annulets, each with three tubercles above the tracheal line, except on the anterior annulet, where the middle one is miss ing ; very indistinct tubercles on subventral ridge. This larva is evidently allied to the Hylotominae, not to Cimbex. TENTHREDININAE. Blennocampa spircece. Feet on segment 8 ; segments divided into five annulets, one cut off before and one behind the three primitive setiferous annulets, which bear three rudimentary spines above the tracheal line, except the middle annulet, where only one is present low down. A group of spines on each division of the subventral ridge. Siobla excavata. Feet on segment S ; segments divided into six annulets, one before, two behind the primitive annulets, which bear fine points, except the middle annulet, where only a few are present low down. PAMPHILIIN^E. Lophyrus lecontei. Feet on segment S ; segments divided into six annulets, two cut off behind the last primitive setiferous an nulet, and one cut off behind the second, the original setae thus present on annulets i, 2, and 4, numerous, developed alike on all ; a group of setae on each division of subventral ridge. Pamphilia ochreata. No feet ; a pair of jointed anal append ages. Segments divided indistinctly into four annulets ; no per ceptible setae. XYELIN^E. No larvae seen by me.* I have some other striking modifications of structure, but the larvae are not yet bred, so I do not know the significance of them. Mr. Ashmead congratulated the speaker upon this work, and said that he considered it of great importance. The annulets and * These larvae have since been discovered. See Psvche, VIII, 213; Can. Ent. XXX, 175, and XXXI, 41. OF WASHINGTON. 221 tubercles were never before made use of in systematic work, and he felt sure these would be found to be of great taxonomic signifi cance. - Mr. Banks presented the following paper : AN AMERICAN SPECIES OF THE GENUS CiECULUS. By NATHAN BANKS. In every group of animals there are a few genera having char acters which ally them to various larger groups, or serve to con ceal their true relationship. In the Acari there are several such genera, and not least interesting of them is CaBCulus. Its general appearance at once reminds one of certain Oribatid mites, viz., Nothrus. And on a closer examination one finds several struc tures which would confirm this appearance. But there are cer tain characters, deemed by acarologists of much importance, which place the mite near a quite different family, the Trom- bididas. These important characters are the palpi, the structure of the coxae, and the peculiar eyes. The eyes are almost exactly as in Trombidium, an arrangement not found elsewhere in the Acari. But the dorsal shields, the rough spinose legs, and the large ventral openings are characters wholly foreign to the Trombididae. The early writers placed the genus after Oribata, and Gervais suggests that it has some affinity with Phalangium. In 1877 Canestrini and Fanzago wrote a paper on the genus and erected for it a new family, which they placed near the Trombididae. This position it has since occupied in all classifications. Canestrini and Fanzago gave the genus* a new name, Hoplopus ; because they thought Caeculus inappropriate, and called the family Hop- lopidas. But since Hoplopus is a synonym, the family should be called Cajculidas. The genus is represented in southern Europe and northern Africa by one species, C. echiuipes. Last spring Mr. H. G. Hubbard sent me a mite taken at Palm Springs, California. It proves to belong to Caeculus, and differs from the typical Euro pean species in several minor particulars. Caeculus americanus, n. sp. Length 1.3 mm. Black, soft portions rather reddish-brown. Cephalic shield more than twice as long as broad in front, twice as broad behind as in front, sides sinuate, angles rounded; from the front margin there projects four spatulate hairs or scales; there are two subparallel middle lines not reaching to the hind margin ; under the hind angles arise a double tubercle, each bearing an eye. Anterior shield of the abdomen one- 222 ENTOMOLOGICAL SOCIETY third broader behind than in front, rather concave above, traversed by irregular low ridges, and two longitudinal lines rather nearer to the lateral margin than to the middle. Posterior abdominal shield much broader than anterior, its front border concave, broadly rounded behind, bearing above two scale-like hairs on the front border, four in a transverse line beyond the middle, and four more on hind border. Venter with large anal and genital openings close together. Legs very large and stout, first pair longest but plainly shorter
