By CLARENCE HAmiLton KENNEDy, Cornell University. (Plate XVIII) In the fall of 1913, when I was working with the Argias and Ischnuras of Washington and Oregon’ I discovered that the penis, hitherto overlooked by systematists who had studied the Zygoptera, was in some cases an excellent generic char- acter and in other cases even a good specific differential. In the Fall of 1914, when I was working over my collection of California Odonata and found it expedient to describe two new genera, I went into a careful study of the penis in these and related genera, which convinced me that the penis had characters worth studying and made me desirous of carrying the study further. This opportunity came in the Fall of 1915, when I had the privilege of spending several weeks studying with Mr. E. B. Williamson in his private collection and laboratory at Bluffton, Indiana. At this time I drew two ata) of Washington and Oregon, C. H. Kennedy. Proc. U. S. Nat.

[ July, 16 views each of the penis in over three hundred species of Zy- goptera. Since my arrival at Cornell I have had the privilege of spending altogether two weeks studying the species of Zy- goptera in the collections of the Academy of Natural Sciences of Philadelphia, and of Dr. P. P. Calvert through his courtesy. To date I have drawn the penes of over five hundred species of Zygoptera, having made altogether over one thousand figures, and am hoping to continue the work until the subject is completed, as a monograph. I wish here to thank Mr. Williamson and Dr. Calvert and Dr. Skinner of the Philadelphia Academy, who have so gen- erously opened their collections to me, as it is only through such interest and generous assistance that this study has been made possible. When this work was begun, I felt some assurance that the penis would be, not only a good generic, but also a good specific character. More extended study however has shown that only a monographic study of the penes in the entire group of Zygoptera will reveal just how far these organs can be trusted to show true relationships between species and groups, for it has already become evident that the value is very different in different groups. The accompanying text figure is a diagram showing what seems to me to be the zygopterous penis stripped of its special modifications, in other words what might be its most general- ized form. I have no evidence that this is also its most primi- tive form, as in those genera usually considered most primi* tive the penis may be most fantastic in the complex modifica- tions of these simple parts, so that it appears that there has been a tendency to a reduction in its complexity from the more primitive forms to those more recent. However there are undoubted exceptions to this. The zygopterous penis °On Jan. 1, 1916, Dr. Needham received a copy of Dr. Erich Schmidt’s interesting paper on this same subject of penes (Vergleich- ende Morphologie des 2. und 3. Abdominal-segments bei mannlichen Libellen. Zool. Jahrbuchern. Bd. 39, Heft, 1, 1915.) It was the first intimation I had had that some one else was working on the same subject. Dr. Schmidt has dealt with seventy species of Zygoptera. Vol. xxvii] ENTOMOLOGICAL NEWS. 327 which is an appendange of the ventral side of abdominal seg- ment two consists usually of three segments and two, usually unchitinized folds. Segment 1 is the basal or proximal, slen- der, heavily chitinized shaft. Segment 2 is the moderately chitinized median segment, while segment 3 is the apical or distal segment which folds forward on the median Oe.2. S eg.d. segment and is usually un- chitinized. The median segment ordinarily carries across its ventral surface a fleshy ridge or fold, the inner fold, and across its posterior end the terminal fold. This latter is prob- ably erectile in many spe- Diagram showing the parts usually found ies) Either or both fleshy i ‘R*2%EoPterous pens. folds may be lacking and in the Legion Lestes segment 3 is much reduced. The differences between penes are usually in the shape of the distal or third segment. I have introduced this present series of papers with this one on Acanthagrion to have it appear in conjunction with a paper on some species of the same genus by Mr. Williamson. The study of the penes in this group at once cleared up the hitherto obscure relations of the various forms which had variously been termed varieties and subspecies. Those that have been studied are, as far as the penis is concerned, good species. Mr. Williamson and I were both much surprised when we found the great structural differences existing in the penes of the so-called “subspecies” (ablutum, ascendens, mi- narum'), of gracile. ‘The penes of the thirteen species of Acanthagrion I have been able to examine vary more among themselves in form than those of any similar group of closely related species of Zygoptera. If I had seen the penes only, I Internal fold. Seg.l. Terminal fold. 4The minarum referred to by Mr. Kennedy is the species described by me (anted, p. 314) as kennedui. It was determined independently by Dr. Calvert and myself as minarum, but is probably not the minarum of de Selys—E. B. WILLIAMSON. 328 ENTOMOLOGICAL NEWS. [ July, 16 would have unhesitatingly believed that they represented at least four genera.” The only single character which runs through the entire series is the absence of the internal soft fold. Probably the spines along the shaft are also a character of the entire group but they are so delicate that they have to be looked for spe- cially, and in laterale and adustum I did not notice their ab- sence until the drawings were assembled in the plate. An- other character which runs through the entire group, but which is not so obvious, because it appears in a different form in each species, is one or more outgrowths (septa, lobes, spines, hooks, etc.) which appear along the median line of the dorsal or internal surface of the distal lobe. Outgrowths along this line, though they do occur in a few other genera, are rare. The singular paired outgrowths of the lateral edges of the distal segment, as they are developed in temporale, apicale, gracile, ablutum, ascendens, kennedii, cuyabae, and truncatum, are unusual, though they also appear in other genera. The strangest and least comprehensible development in the entire series is that of the pair of heavily chitinized hooks on the apex of the distal segment in apicale (Plate XVIII, fig. 3). A strong chitinization at this point is all but unique among the more than five hundred species of Zygoptera examined. The terminal soft fold varies in development in this series but I should hesitate to say that it was entirely absent in those species in which it is not figured, as it is at times gossamer- like and, if the specimen is the least dry clings so closely to the terminal segment that the most careful dissection may fail to loosen it. However I can state that it is as a rule poorly de- veloped except in cheliferum, (Pl. XVIII, fig. 26). The following brief notes are to amplify the characters shown in the figures on Plate XVIII. Acanthagrion ablutum Calvert, figs. 10-11. The edges of segment 3, twisted at its base and turned in, form a pair of “shelves” between which is an ill-defined median septum. °Prof. O. A. Johannsen has just called my attention to a condition similar to this in certain genera of Mycetophilidae. In some genera in this family the hypopygium in the male varies between species so much that the parts cannot be homologized.

In conclusion, certain venational characters divide this genus, as it has been understood in the past, but the penis, be- cause of its evident great variety of forms, is of little assist- ance in defining groups among this series of species. How- ever the study of the penis has shown very definitely that we are dealing with structurally, well defined species rather than with subspecies and varieties based, as hitherto, largely on color. In addition I might say that I shall treat in another paper of a series of species in which a condition exists just opposite to this which occurs in Acanthagrion. In this other series what are apparently generically distinct species have almost identical penes. 330 * ENTOMOLOGICAL NEWS. [July, 16 EXPLANATION OF PLaTE XVIII.

Dolichopselephus has recently been regarded by Szépligeti? as a synonym of Heterocola Forster, a genus rep- resented by three European species. The characters given by him for Heterocola however, do not agree with those given by Ashmead for Dolichopselephus in several respects and it is evident that Szépligeti has been led by the peculiarly modified maxillary palpi to consider the two genera inseparable. They may be easily distinguished as follows: Antennae with not over 20 joints; metathoracic spiracle lying very closestouthe =pleural caninas.2- 4 see eee eee Heterocola.

One of the common complaints of the time in entomologt- cal, nay zoological circles is the difficulty of obtaining the aid of specialists to identify material. Every specialist becomes flooded, even overwhelmed, with the quantity of animals, of insects, which he is desired to determine. Delays of months or of years ensue and he who wishes his collections examined by competent authority must often send them to the one who will report on them the soonest, rather than to the one whose knowledge and carefulness are greatest. The conscientious specialist himself is obliged to decline to add to the tasks which the eager collector or museum officer presses upon him. Under all the conditions, it is inevitable that some, not really fitted to identify species, take up the work without a full realization of all the safeguards to identification that honest work demands. It is not enough to compare specimens with others already tagged, it may be erroneously. Constant recourse must be had to original descriptions and to other published sources of exact information. Comparison of speci- mens is, indeed, important, for thereby the confounding of two or more forms under one name is discovered. The ulti- mate appeal is, of course, the comparison with types, but few of us have access to these courts of last resort. The constant checking up of new material, as well as that previously determined (including types where possible), with the literature is the obvious duty of everyone who undertakes to pass definitely on the systematic status of speciments of nat- ural history. A Correction for Parnassius smintheus (Lep.). I chanced to see a recent issue of ENToMoLocicAL News last night, and noticed under your article on Parnassius that I am quoted (Vol. XXVli, page 213) as recording smintheus from southeast of Calgary.

An elementary text book of fresh- water biology for American students. By James G. NEEDHAM, Professor, and J. T. Lioyp, Instructor, in Limnology in Cornell University. 1916. The Comstock Publishing Company, Ithaca, New York. 9% x 6% inches, 438 pp., 242 figs., 19 initials and tail pieces. Price $3.00. This book has developed in connection with the course in general limnology at Cornell University, begun in 1906. Its scope is naturally much wider than that of entomology, but insects figure largely in its pages. After an historical introduction (Chap. I, pp. 13-24), the na- ture and types of aquatic environment are described (Chaps. II, III, pp. 25-99). Under Chapter IV, Aquatic Organisms, pages 100-158 are concerned with plants and pages 158-241 with animals; of the latter section, the insects occupy pages 195-230, with 37 figures. Owing to limitations of space, smaller taxonomic groups than families are not considered. Perhaps the most interesting part of the book is Chapter V, Adjustment to Conditions of Aquatic Life (pp. 242-292), such as flotation, improvement of form, avoidance of silt; withstanding the wash of moving waters, etc., etc. Aquatic Societies, both limnetic and littoral, are discussed in Chapter VI (pp. 293-375), which vies with its predecessor in attractiveness. Finally, Inland Water Culture is treated» in Chapter VII (pp. 377-412). There is a bibliography under author’s names arranged alphabetically (pp. 413-419) and an index (pp. 42I- 438). As mentioned above, the insects are formally treated in Chapter IV, but’ many other references to them occur in subsequent pages. The reader will not find in this volume any keys.to the identification of aquatic organisms but the numerous figures and the text will enable him to become acquainted with the names, habits and environmental relations of many plants and animals associated with any group of water beings in which his interest chiefly lies. “It is the ecologic side of the subject rather than the systematic or morphologic, that we have emphasized,” ,say the authors, and every entomologist looking into this book will be the better for such a consideration of aquatic life as he will find here. The text is pleasingly written, the type is clear and large, the illus- trations useful or beautiful. We must, however, utter a protest against a fault too common with our American books. This volume is too heavy; it weighs 38 ounces, a quality which has already discouraged us from carrying it with us to while away an enforced wait when read- ing was almost the only resource. The common practice of printing half-tones in the midst of the text, with the use of coated paper throughout, is the responsible cause—P. P. C. (Adv.) 1 as EXCHANGES.

THE AMERICAN ENTOMOLOGICAL SOCIETY announces the inauguration of a new series of entomological papers of. monographic character, to appear as frequently as suitable manuscripts and sufficient funds are available, and to be called the Memoirs of the American Entomological Society. The Memoirs are to be of a large octavo size, and each paper will form a separate number complete in itself. As the individual numbers will proba- bly vary greatly in the number of pages, above a minimum required for the series, no fixed price per number will be made, but the charge will be computed for each unit upon a pagination basis. The first number of the Memoirs was issued during the month of June, and appropriately contains ‘‘The Cresson Types of Hymenoptera,’’ by Ezra Townsend Cresson. This contribution will prove of the greatest value to the taxonomic Hymenopterist working on American forms, as it is a full catalogue of the 2737 species described by the author, with original references, selection of single types, location and number and condition of the same, to which is appended a bibliography of the entomological papers of the author. This number contains 140 pages and will be mailed upon receipt of price $2.00. AMERICAN ENTOMOLOGICAL SOCIETY, Logan Square, Phila’da, Pa. N.
