No. 3. The Penes in Neoneura and Related Genera. By CLARENCE HAMILTON KENNEDY, Cornell University, Ithaca, New York. (Plates XXI-XXIII.) In the first* of this series of articles was shown a series ot penes in the genus Acanthagrion, whose divergent characters showed but little generic cohesion, a series with such abrupt changes in form from species to species that their characters could not be used in defining generic limits though they were exceptionally valuable in differentiating species. In the second paper+ was shown a series of penes in the Hawaiian genus Megalagrion, in which, though the genus in- cluded forms of diverse venation, size and body structure, the penes ran so close to each other in structure that the en- tire series of over twenty could not be divided into groups and * Ent.

[July, 17 the penis could not be used as a specific character because of the lack of sufficient specific differences. The present paper deals with a third condition, one that can be said to be intermediate between the preceding. It deals with a group in which the penis is a good generic as well as a good specific differential. As in the second paper, this group was chosen because of its immediate availability through Mr. Williamson’s review of the genus Neoneura and his recent work on related genera.* It is offered as a sup- plement to his delimitation of genera and species in this Legion. As in venation, the penis in the Legion Protoneura is re- duced to a comparatively simple form, though it is not as re- duced as in the Legion Lestes. Notwithstanding this reduc- tion, ample variety of form yet occurs for the distinction of genera and species. By referring to the description and text- figure in my ftrst article (Joc. cit.) it will be seen that the penis in this group approaches nearly to this simple, generalized form. In most genera of the Legion Protoneura the terminal fold is lacking, though even this occurs in the genera Palaem- nema and Platysticta, while it appears in a less degree in Dis- paroneura, Caconeura and Isosticta. In the first series of figures accompanying this article are shown the penes (as far as I have been able to obtain them) of the type species in the greater number of the genera now accredited to this Legion.t With each, where possible, is shown the penis of a second species in the same genus to show at a glance those characters common to the two (generic characters) and those characters peculiar to the individual (specific characters). In the second series of figures are shown the penes of the species of the genus Neoneura. *Notes on Neotropical Dragonflies or Odonata, Proc. U. S. Nat. Mus., Vol. 48. May 12, 1915, pp. 616-636.

Also the penes in this group show certain characters in common which might induce one, not familiar with the penes of the other Zygoptera, to attempt a definition for the group. Un- fortunately many parallelisms occur in the form of this organ in the various genera, so that in using the characters of the penis to untangle classification the form of the penis has always to be considered in conjunction with any and all other available characters. Among the startling parallelisms is the resemblance be- tween the penes of Palaemnema and Bayadera the latter of which is in the Agrionidae, [Calopterygidae] another family of the Zygoptera. Certain species in Disparoneura (not figur- ed in this series) have penes almost identical with that of Amphipteryx and nearly every one of the other generic forms can be paralleled in the Legion Coenagrion.. The forms il- lustrated here are given merely to show a series in which the penis can be used to aid in the definition of genera. In this series, however, the penes show two or possibly three lines of evolution, which on a more complete study of the genera involved may show groupings within the Legion. Mr. Williamson has even suggested that this Legion may be an unnatural group, being merely the association of those forms of reduced venation, which have developed independently in various other Legions. The evidence for and against this will be given in a later paper after a more thorough study of this group has been made. The following notes point out what may be considered generic characters in the genera illustrated.* Palaemnema paulina Drury, figs. 1-2, genotype. Both soft folds present. Segment 3 two-lobed, the tips flattened into incurved hooks. * The arrangement of genera used ee Kirby) Gat Odonata, London, 1890, has been followed. 292 ENTOMOLOGICAL NEWS.

The second series of illustrations deals with the species in the genus: Neoneura. In this genus the inner edges of the anterior lobes turn in. In Neoneura rubriventris, figs. 69-71, the apical lobes are reduced to mere rudiments. In Neoneura mariana, figs. 63-64, the terminal lobes are best developed. Usually they are pointed, but in sylvatica they have rounded tips. It is not necessary to go into detail concerning these as the illustrations show how a single type can appear variously modified in a series of congeneric species, ieee q bool al i” 7 _ rf > : - - ’ a ' Fst as ‘ o ( iad a : \ Ent.

As was stated at the be- ginning of this article, only a monographic study of the penis throughout the entire sub-order of Zygoptera can show what value to place on the penis in any group as a systematic help. In all the work this character appears to be suggestive rather than positive and final. EXPLANATION OF PLAtes XXI-XXIII.

Vol. xxvii] ENTOMOLOGICAL NEWS. 295 Life History and Habits of the Margined Water Strider, Gerris marginatus Say (Hem., Het.). By J. R. pe ta Torre BuENo, White Plains, New York. This species, Gerris marginatus, Say 1832, lacustris Kirby 1837 (sec. Van Duzee, Ch. L.), is the common smaller Gerris spread over all the United States, a: familiar form on ponds and in the bays of lakes. It has been recorded in Canada from British Columbia to Quebec, and in the United States from Oregon and California to Georgia and Texas, but twenty- three States are still to be heard from, including the greater part of the Mississippi Basin. Gerris marginatus belongs in the subgenus Gerris sensu strictu (=Limnotrechus) which contains the smaller members. This subgenus, however, presents intergrading forms with subgenus Aquarius among the exotic species, Gerris chilensis Berg forming the passage. The character of the first joint of the antenna shorter than the second and third taken to- gether, in connection with the smaller size, serves to separate Gerris from Aquarius. Two species of the subgenus in the Eastern States may be confused with it, namely, Gerris buenot Kirkaldy and Gerris canaliculatus Say. The former is small- er in size and has more pronounced abdominal sutures to- gether with a flavescent marginal line on the anterior prothor- acic lobe. The second species, while it may be larger or small- er, has a distinctly more slender form and noticeably long and slender legs and antennae. The genital character controls; it is well-figured by Parshley’. Weiss’ experimented with G. marginatus, apterous, as to orientation to water, or, using the more technical expression, positive hydrotropism. He found that up to 9 yards distant from a pond they immediately made their way back: at 10 yards they began to experience difficulty ; at 15, it increased, while at 30 or 4o yards they seemed to lose their bearings, moved aimlessly about and after a time seemed unable to find their way back to the water. The species is a ligt5. Ent. News xxvii: 103, fig. b. 21914. Can. Ent.: 33. 296 ENTOMOLOGICAL NEWS. [July, ’17 strong flier, and I have found it in ocean beach drift in July, on the shores of Long Island*. Gerris lacustris, so Griffini says‘, touches the water at times with the abdomen, which it rests on the surface. I have not seen marginatus do this. He also states that it has been observed to be attracted by mirrors. Gerris marginatus begins to oviposit early in the spring; the eggs hatch out in ten days to two weeks, depending on the temperature. After five molts it reaches the adult in from 5 to 6 weeks. Unlike its larger congener remgis, it is a dweller in still waters by preference. Here at times it gathers in large numbers. In strong winds it hugs the shore, particularly if it blows that way. From early March to late November it may be found busy about its domestic affairs. The height of its abundance is between April and September. In early April they have been noticed mating; by May 20 to 26 adults and nymphs in one or two stages are seen together, and so through June and July, when they are found in several stages together. Its food is the same as that of remigis, except that being small- er it is not able to overcome quite such large insects. I have seen marginatus trying to capture Notonecta undulata which had flown to a pond and was on the surface struggling to submerge. The Gerris avoided reprisals by jumping up from the surface. On the other hand, it is one of the few water- bugs that fall a prey to frogs, and is, in fact, the only one I have seen recorded. Its structure is characteristic of the genus; in fact, belong- ing in the typical subgenus, it closely approaches the generic and subgeneric type, Gerris lacustris Linné. In common with this species, marginatus rejoices in the phenomenon of ptery- gopolymorphism. Kirkaldy says®: “lacustris has provided me with more variations—at least six—than any other species. It is noteworthy that in the brachypterous forms, the two ab- breviated elytra are not always equal in length and develop- 31915. Ent. News xxvi: 277. 41894. Gli Insetti Acquaioli p. 39. . 53899.

Vol. xxviii] ENTOMOLOGICAL NEWS. 207 ment in the same specimen.” Gerris marginatus exhibits the same gradation from apterous to macropterous, going from one to the other by imperceptible degrees. Yet it is essentially an alate species, since the bulk are fully winged and only a small number totally apterous, with an indefinite proportion of varying degrees of brachypterousness. In this it differs from remigis and other species of the subgenus Aquarius, which are in general totally apterous with a very small number —an occasional specimen here and there—fully winged (ex- cept conformis, always found fully winged, and alastor Bueno MS., nearly always with rudimentary wings only). The most complete study of pterygopolymorphism is Reuter’s “Poly- morphisme des Hemipteres®.”” Here he covers the entire sub- ject and hazards explanation based on selection. In Gerris marginatus and in general in the family, I see a gradual trans- formation to apterousness, through disuse, as exemplified by our remigis and the European najas, the fully winged being the primitive form, adapted to an existence on the water from an antecedent Reduvioid land bug, whose mobility depended on these members. The stream species, being in general safe from the consequences of droughts, are so independent of wings for transportation that these organs are nearlv cone in most of them. The species inhabiting land-locked bodies of water must, however, always have some means of travelling if the water on which they live dries up, as so frequently hap- pens with small ponds or water-holes. Hence wings still nor- mally persist in these forms. Structure, progression, respiration, reproduction are as in G. renugis. Dufour (op. c., p. 199), states that in paludum the digestive system is as in canalium, excepting the salivary gland. Gerris marginatus, so far as known, has no egg parasites. Adults and nymphs are sometimes found with larval mites at- tached as in remigts, particularly about the head and thorax. Egg. The egg is cylindrical, truncate at one end and round- 61875. Bull. Soc. Ent. Fr., pp. 225/36. 298 ENTOMOLOGICAL NEWS. [July, 17 ed at the other. The chorion is roughly shagreened, and under magnification x 975, shows very shallow pits. It has no indications of a lid or line of weakness along which to split. Length, 3 mm.; diameter, 1 mm. The ova are clear white when first deposited, but change to brown as development of the embryo progresses. In hatch- ing, the nymph emerges through a longitudinal split beginning at the truncate end and running about one-half to two-fifths the length of the egg. Three females gave 30 ova in four days. They were fastened a few on top of a piece of cork in the aquarium, and most in a clear colorless glue or jelly, along the edges of the cork and under the surface of the water. Gar- man’ says the eggs are attached to aquatic plants. Dufour re- marks (op. c., p. 347) “I have kept in vessels of water with water plants pregnant females of Gerris paludum, and I have assured myself they deposit their eggs one after the other, but not in contact, in a kind of mucilaginous jelly.” After eight or nine days the little bugs emerge. On June g, one year, I secured thirty nymphs. Some seemed to molt right away, which I assume to be casting the amnion. In this connection, Dufour also says (1. c.) “I have seen the larvae born and I have sometimes found caught in the opening of the egg a fine membrane which was doubtless the immediate envelope of the larva, or which covered the interior of the egg-shell.” This pellicle cast by Gerris marginatus immediately on emerg- ing covers the body legs and antennae, and is extremely hairy. It is so soft it loses its shape completely, although all the joints of antennae and legs are apparent and the tibial combs are all visible. All the tarsi, on emerging, are I-jointed; all claws subapical; the antennae are very stout, the last joint as long as the others put together, and so far as could be seen in bal- sam mounts, apparently 3-jointed only. The lancets are also cast with this skin. It is an open question in my mind whether or not this may 7189 ~=Bull. Ills. St. Laby, N. H., iti: 172. Vol. xxviii] ENTOMOLOGICAL NEWS. 299 be considered a true molt. There are no perceptible differ- ences between this nymph and the next, either as to size or structure, except the possible 3-jointed antennae noted. I am inclined to consider it akin to the subimago molt of the may- flies, rather than as a true ecdysis. This amnion, for want of a better term, resembles that covering certain Orthoptera, ex- cept that it is a complete pellicle. If it is a true molt margina- tus has six. It may well be that this initial molt has gone unnoticed in the other Heteroptera, owing to the very diaph- anous skin being blown away as soon as cast, and, in water, be- ing unseen through its transparency and quickly destroyed by the mechanical action of the element. First Instar. On emerging the nymph is about 1 mm. long, pointed oval in shape. The cylindrical antennae are 2/3 the length of the body, the first joint as long as 2 and 3 together, and 4 as long as the other three. The head is translucent honey-yellow, quite wide between the eyes, which are small, prominent, round and black. The rest of the in- sect, including the legs, which are rather thick in proportion to the size, is translucent white. There is a broad black stripe down the middle which crosses a similar stripe on the thorax and ends in a point at its cephalic margin. The abdominal segments are variously marked by the same black bands around the abdomen at the connexivum. The dorsum only is described, as it was taken from a living specimen. The tibia of the anterior pair of legs is longer than the femur and of the second pair as well, but in the third pair, the femur is longer. The anterior tarsus is short and stout and the two other slender and long; all are single-jointed, with subapical claws. All the tibiae have combs. The rostrum is 4-jointed, stout, joints 1 and 2 subequal, shortest, 3 longest, 4 longer than either 1 or 2, tapering; no tactile hairs were noted at the tip. The legs are set very far back, which means that the abdomen is very short, the abdominal segments being narrow. The thorax is about 4 to 5 times as long. In molting the vertex and front lift off like a lid hinged at the cly- peus, and the thorax splits straight down the middle. The lancets are cast with rostrum, and there are no signs of tracheae in the cast skins. The second true molt takes place in 3 to 5 days. Second Instar. The antennae in this instar have joint 4 shorter than the other three together, 2 and 3 being subequal, and 1 twice as long as either. The first pair of legs continues the shortest, the second is the longest; the middle femur and tibia are subequal, in the other two, the tibia is longer than the femur. The thorax is two and a half times 300 ENTOMOLOGICAL NEWS. [July, ’17 as long as the abdomen, which has 7 and one genital segments. The prothorax is distinct. Varying from 3 to 5 days, the bug molts for the second time. Third Instar. The antennae continue to change. The 4th joint is still the longest, 3 the shortest, followed by 2 and 1 in the order given. The eyes are reniform. In the legs, the femora are longer than the tibiae in the 1st and 3rd pairs, and subequal in the second. The abdo- men is longer and the legs appear set less far back. In other respects there are no perceptible changes. The third molt follows the second in 3 to 6 days. Fourth Instar. In this instar the antennae continue to change, and the differences in length are not so great; joint 4 is still the longest, but 2 and 3 are subequal and the shortest, 1 being not greatly shorter than 4. The femur and tibia of the anterior legs are subequal; and the femur is longer in the 2d and 3d pairs. The hind femora have dark spots from which arise long setae. The abdomen has further increased in length, the segments being wider and more distinct. Joint 3 of the rostrum is the longest, 2 is the shortest and 4 is as before, and nearly equal to 1. All tibiae have combs and all claws are simple. The fifth instar is reached in 3 to 5 days. Fifth Instar. In this instar the form and general appearance of the nymph begin to approach more closely to the adult. The head is rounded and set with long setae, the eyes are reniform. In the antennae joints I and 4 are subequal, and longer than 2 and 3, which are also subequal. The chief antennal difference is at the base of the third antennal joint which has a pedicellate appearance. The rostrum is the same as before, except that the 3d joint is much longer in proportion. The prothorax is differentiated and the mesothorax distinct, with a minute scutellum. The wing-pads are notable and reach half-way to the 4th abdominal segment. The legs are as before, with thicker femora than tibiae. The second and third femora have the dark setigerous spots, and the third in addition is set with spines. The middle tarsi are much elongate, and all the tarsi continue single-jointed. Abdominal segments are very dis- tinct and the two genital segments very prominent. In the cast skin two long slit-like spiracles are seen in the mesothorax in front of the intermediate coxae. In five to seven days the little bug molts for the fifth and last time, and reaches the adult. The chief changes in structure in the external skeleton are the two-jointed tarsi, the node at the base of the third joint of the antennae, the much larger eyes in comparison to the head and the prothorax and mesothorax fused together. The entire internal anatomy of Gerris marginatus is still to be worked out, and the external organs of respiration as well.

Bruner collected three species of the wasp-like Panurgid genus Psaenythia at Carcarana, Ar- gentina. They were sent to the National Museum, and are now in my hands for determination. One proves to be a fe- male of P. picta Gerst., but the others are considered new. Psaenythia thoracica crawfordi n. subsp. Larger than true P. thoracica from Parana, about 8.5 long in both sexes; female with lower border of clypeus black, and the black on disc extending upward as two large wedge-shaped marks; supra- clypeal area black; mesothorax, scutellum, postscutellum and two trans- verse marks on basal part of metathorax red; pale yellow abdominal bands narrowly interrupted on first two segments, constricted but not interrupted on third and fourth, very narrowly interrupted on fifth. Male with face cream-colored below antennae, the supraclypeal mark notched above; anterior margin of mesothorax broadly black; no red on metathorax; all the abdominal bands interrupted. The female, in my collection, was received from the National Museum, labelled P. thoracica Gerst. by Mr. Crawford. The male (Bruner 33) evidently belongs with it. In spite of the greater size, I should not separate this from P. thoracica (de- scribed from the male), but for the fact that Friese has the female of that insect (from Villa Rica, Paraguay), and states that the abdomen has on each side of segments 1-5 a small yel- low three-cornered spot. Since Friese’s insect is from a region comparatively near the type locality, there is no reason to doubt that it represents the species correctly ; P. thoracica crawfordi is evidently a well-marked subspecies from the desert regions of the interior. Psaenythia pachycephala n. sp. é.—Length about 10 mm.. robust; head very broad; eyes rather small, green, strongly diverging below. Black, with clear ferruginous legs, the markings cream-color, those on face and mandibles lemon- yellow. Mandibles long, yellow on outer face except at apex; clypeus (which is extremely broad and low), labrum, large dog-ear marks, and space between clypeus and dog-ear marks and orbits yellow, the lateral yellow ending above horizontally, not quite reaching level of top of dog-ear marks; a cream-colored mark on upper part of each Vol. xxvii] ENTOMOLOGICAL NEWS. 303 cheek behind; facial foveae oblique; vertex shining but well punctured; flagellum clear ferruginous beneath except at base, antennae otherwise nearly black. Mesothorax and scutellum shining and sparsely punc- tured, metathorax dull; cream-colored markings consisting of inter- rupted line on collar, ends of tubercles, spot behind tubercles, spot at each anterior corner of scutellum, band on postscutellum, spots on knees (extending to stripes on anterior femora), and bands on abdom- inal segments 1-6, on first segment reduced to a pyriform mark on each side, on second and third broadly interrupted, on fourth narrowly in- terrupted, on fifth and sixth hardly more than constricted; tegulae clear fulvous; wings yellowish, dusky apically, stigma amber-color; apical plate of abdomen broadly truncate, the truncation slightly ex- cavated. (Bruner 509.) @ —Length about 10 mm.; differing from the male thus: Head or- dinary, though broader than long; mandibles black, with a ferruginous patch; face black, except for a pair of large quadrate patches, broader than long, taking in the dog-ear marks and the space between these and the orbits; mesothorax and scutellum rather densely punctured; bands on first two abdominal segments rather broadly interrupted, on third narrowly, on fourth very narrowly, on fifth entire; fringe at end of abdomen black; spur of middle tibia as long as basitarsus, re- motely short-pectinate. (Bruner 60.) The sexual difference in the sculpture of the thorax is paral- lel with that observed in P. philanthoides Gerst. Related to P. rubripes Friese, from which it is known by the much darker antennae, spotted scutellum, and the large light patches on face of female. According to the description, P. rufipes Holmbg. appears to be very similiar, differing by the color of the flagellum and the form of the face-markings. Schrottky states that rufipes is a variety of P. picta, which P. pachycephala certainly is not. —____-—+12e»>—-— Physiographic Divisions of the United States.

[ July, 17 Origin and Development of the Photogenic Organs of Photuris pennsylvanica De Geer (Col.).* By Wa ttTerR N. HEss. In spite of the fact that the light organs of fire flies have been the object of much study during the past century, com- paratively little has been done on their development. How- ever, during the past few years this phase of the subject has received more attention, though as yet, no one has definitely demonstrated their embryonic origin. There are at present three conflicting views regarding the origin of the photogenic organs. One view is that they are modified hypodermal cells, another that they are formed from both ectoderm and mesoderm, and lastly, that they are derived from fat cells. Of these three views, that of the fat cell origin has been the most generally accepted. Among the earlier workers who favored the idea of ecto- dermal origin was Owsjannikow (1868), but his observations are of little value since he studied only the adult organ. The question of origin can be settled only by a study of the development of the photogenic tissues. With the excep- tion of two recent papers, Vogel (1912), and Williams (1916), this has not been done by any one except Dubois. Dubois (1898) studied the development of both Lampyris noctiluca and Pyrophorus noctiluca. He believed that he was able to follow the development of the photogenic organs through the different stages, from the beginning of segmentation, to the adult insect. He discovered a close histological resemblance between the blastoderm cells and the photogenic cells of the larva, pupa and adult. Furthermore, he concluded that the cells of the hypodermis multiply, and by proliferation form directly the photogenic organ of the larva. For some reason Dubois’ work has attracted little attention and is practically ignored in general discussions of the sub- ject. Moreover he misinterpreted the normal structure of the body wall in Lampyris, and for this reason his conclu- * Contribution from the Entomological Department of Cornell Uni- versity. Vol. xxviii] ENTOMOLOGICAL NEWS. 305 sions have been severely criticised by the few who have dis- cussed them. Wielowiejski (1890), in opposition to Dubois, states that the so-called reflective or urate layer of the photogenic organ is derived from fat cells; the light giving or luminous layer, on the contrary, is composed of cells derived from oenocytes, hence ectodermal. Here again the statements are based on a study of mature organs, and hence are not conclusive. With the exception of the two previously mentioned papers by Vogel and Williams, all authors who favor the theory of fat cell origin have based their conclusions only on a study of the adult organs. Many of these, including Leydig (1857), Schultze (1865), Wheeler (1892) and Berlese (1909) seem to be of this opinion, largely because the structure of the mature organ resembles somewhat that of fat cells, and also because certain cells of the photogenic organs secrete urates and other products, comparable with fat cells. Recently two important papers have appeared which ap- parently definitely settle the question in favor of the fat cell origin, one by Vogel (1912), the other by Williams (1916). Vogel studied the embryonic development in Lampyris noc- tiluca, beginning with a stage in which the organ was already clearly differentiated. He made a comparative histological study of its cells and those of the neighboring tissues, from which he concluded that the cells of the photogenic organ, in this stage, agree with the neighboring fat cells in shape, size and relations of their nuclei. On this he based his conclusions that the light organ arises from fat cells. It should be noted that Vogel found the organ in its early development closely applied to the hypodermis, while at a later stage it was definitely separated from it. Williams (1916) worked upon our native species, Photuris pennsylvanica, and apparently confirmed completely the work of Vogel. He maintains that the cells of the photogenic organ form a gradual gradation from the rather dark pigmented cells lying against the hypodermis, through those on the side towards the fat cells and continuous with them. 306 ENTOMOLOGICAL NEWS. [ July, 17 Unaware of Williams’ work, which did not appear until late December, the writer had undertaken a study of the embryonic development of the photogenic organs of Photuris pennsylvanica. This work was at the suggestion of Dr. W. A. Riley, to whom the writer is indebted for helpful advice and criticism in the completion of this paper. On the basis of this work he is forced to conclude that neither Vogel nor Williams studied the organ in its earliest development, and that they drew mistaken conclusions from observations of organs already developed beyond the critical stage. Material for study was obtained by confining the adult in- sects in small jars that were partly filled with earth and moss. Since oviposition occurred very readily in captivity, it was easy to obtain a complete series of eggs by removing the in- sects to different jars each day. During the summer of 1916 the eggs of this species hatched in from 25 to 27 days, depend- ing on temperature, with an average of 26 days. Eggs were killed in hot water, dehydrated and imbedded in paraffin. Sections were cut three and four microns thick. As it was often difficult to find the eighth abdominal segment, sagittal sections were by far the most satisfactory. Heidenhain’s iron haematoxylin was very satisfactory for staining. Various other stains were tried with less success. Eosin was some- times used as a counter stain. It was found in the 14-day embryos, that the hypodermis on the ventro-lateral portion of each side of the eighth ab- dominal segment, in its anterior region, showed a definite thickening, due to proliferation and enlargement of the cells, as shown in Fig. 1, (H). The nuclei of the cells were also larger than those of other hypodermal regions. In the 15-day embryos the organ appeared as a distinct nodule which projected from the inner surface of the hypo- dermis (Fig. 2; P). At this stage there was no evidence of any separation from the hypodermis. In fact the hypoder- mal cells extended up slightly between the cells of the nodule itself. By studying a large number of embryos it was definitely Vol. xxviil] ENTOMOLOGICAL NEWS. 307 determined that there was no evidence of any relation between the fat cells and those of the nodule, in this, or the 14-day embryos. At this age the cells and nuclei of the nodule are much larger than those of the hypodermis. In fact they somewhat resemble the fat cells, though the nuclei are larger. Moreover, the chromatin in the nuclei of the photogenic organ is of a coarse.irregular nature resembling closely that of the Fig. 1.—Sagittal section of the ventro-lateral eighth abdominal segment of a 14-day embryo through the middle of the photogenic organ.

[ July, 717 hypodermal cells, rather than that of the fat, which is of a finer nature. The cells of the light organ at this stage appear somewhat vacuolated, especially those farthest away from the hypodermis. This fact is not surprising since this portion soon forms the less dense or reflective layer. The hypodermis itself often shows a vacuolated condition. In the 16- to 17-day embryos the organ is completely sepa- rated from the hypodermis, except at its two ends where it remains attached, the organ being elongated in the direction’ of the two attachments. The appearance of the photogenic cells at this stage is very similar to that of the 15-day em- bryos, except that their cell boundaries seem more distinct. However the cells farthest away from the hypodermis appear more vacuolated. Until now, cell division has .been but slight, however at this time these large active nuclei are di- viding considerably. From Vogel’s and Williams’ descriptions of the earliesi condition of the light organs that they observed, one would be led to believe that it was the study of this stage of de- velopment on which they based their conclusions regarding its origin. At this time the fat cells lie in rather close prox- imity to the light organ, and somewhat resemble it. In embryos 19 to 20 days old, there occurs a differentiation of the cells of the photogenic organ, by which the two layers are formed. The tracheal and nerve connections become fully established about this time, for in the 22-day embryos light was being emitted from the photogenic organ. In the 26-day embryos (Fig. 4,) the two layers are very distinct. Cell boundaries were definitely observed in the luminous layer, though no cell walls were distinguished in the reflective area, -At this period there is considerable dif- ference in the nuclei of the two regions. Those of the re- flective layer appear smaller and more elongate than those ot the luminous area. -The cytoplasm of the luminous portion is very granular and appears slightly alveolar, while-that of the reflective layer, though somewhat alveolar-like, contains com- paratively few granules. Vol. xxviii] ENTOMOLOGICAL NEWS. 309 The narrow hypodermal ligaments which are continuous with the hypodermis and the photogenic organ, often appear longitudinally striated, due probably to a slight modification of the hypodermis in those regions. In a sagittal section these attachments are continuous longitudinally with the reflective layer, the region between these attachments next to the hypo- dermis being occupied entirely by the luminous cells. Since the reflective layer lies like a cap over the inner portion of the photogenic organ, its cells cover all of the organ except that portion next to the hypodermis. At the meeting of the American Society of Zoologists, at New York, in December, 1916, Dahlgren reported observa- tions which he had made on the development of the adult or- gans in the pupa of Photuris pennsylvanica. He found that the larval organs degenerated, and that new ones were formed, in different body segments, by the proliferation of hypodermal cells. Williams in his work on the development of the light organs in the pupa concludes that they are derived from fat cells. However he states: “The photogenic organ, when in the process of formation, frequently suggests a hypodermal origin, for it is then rather structureless and closely applied t@the body wall. Indeed some sections show the hypodermis sending up extensionsbetween the cells of the organ.” My observations on the pupal devélopment of the photogenic organ, though essentially the same as quoted from Williams’ paper, have led me to conclude, as Dahlgren, that the adult organs in the pupa arise from hypodermis. Wheeler and Wilhams (1915) in their study of a my- cetophilid fly of the New Zealand caves, find that the light organs are a modified portion of the Malpighian tubules. These structures, as is well known, are of ectodermal origin, and this furnishes a clear instance of light organs from the ectoderm in insects. All the evidence which I have obtained from the studies above outlined, strengthen my belief that Vogel and Will- iams were mistaken in their interpretations of the early light organ, and that, instead of arising from fat cells, the em- 310 ENTOMOLOGICAL NEWS.

The Philadelphia collections contain material of all the species of Dermaptera native to, or adventive in, these regions. It is the purpose of the present paper to list the native species, giving their synonymy and in each case the first incorrect use of a name for the species based on material from the re- gions here considered; to record hitherto unreported material before us, and to give briefly the local habitat and known dis- tribution of each species. One new species is described. The nomenclature shows but little recent change; annulipes hav- ing been transferred by Burr from Anisolabis to Euborellia. while the series now at hand prove beyond question the dis- tinctness of the species of the Unidentata Group of the genus Prolabia found in Hayti and in the southeastern United States, the correct name for the latter insect being pulchella of Serville. Though the different North American species have been frequently mentioned in the literature, few studies in any way comprehensive have appeared.’ The order is but weakly represented in the regions here treated, except in the subtropical and tropical areas of the southern United States, and constant field work has been nec- essary to assemble even the small total here recorded. Fifteen species are represented, of which four may be said to be confined in distribution to the restricted tropical areas 1Of these the most important are :— 1876.

N. S. P.]. This species is usually found under the bark of dead trees. We have found it only on magnolia and birch. The insect has a very wide distribution over the southern and eastern portions of the United States, but is so rarely en- countered that the records give little definite information as to the limits of its distribution. In Florida it has not been taken south of Enterprise. The most western records are Clifton and Columbia, Texas. The most northern are Dallas, Texas*; Arcadia, Louisiana; Cumberland Gap, Kentucky, and Philadelphia, Pennsylvania. The insect has once been found locally in very large numbers and has been reported common in Texas by Belfrage. Over the greater portion of its dis- tribution in the United States it may, however, rightly be termed a rare species. The distribution in the Americas of this species and Doru lincare, are the widest known for any non- domiciliary earwigs of the New World. 5. Spongovostox apicedentatus (Caudell). 1876.

The size is quite variable, ranging from 4 to 7 mm. in length. Type (male) from Melrose Highlands, Massachusetts, in my collection. Paratypes from Melrose Highlands, Massachu- setts, and Ithaca, New York, Melrose Highlands Laboratory and Cornell University collections. April and May. Some specimens in Dr. J. M. Aldrich’s collection from La- fayette, Indiana, differ only in having a much larger “pra,” in having numerous setulae among the acrostichals, and more abundant and larger setulae upon thorax and abdomen. This species differs from H. maculata St., in the chaetotaxy of the legs and in the structure of the hypopygium of the male; from H. unilineata it differs in having narrower genae, in the form of the fifth sternite and in size. H. maculata has not yet been taken in New York; my previous reference to it should be applied to 1. paludis. PROSALPIA. This genus resembles Hammomyia and Hylephila in hav- ing an elongate anal vein, a pilose lower surface of the scutel- lum, and narrow front in both sexes, but differs from the former in having a bare or pubescent arista and from both in not having the head inflated. The two species recorded from North America in Aldrich’s catalogue may be distin- guished as follows. a. Thorax and abdomen shining black, without pruinosity. Female. arelate Walker. aa. Thorax brownish gray with darker vittae; opaque. silvestris Fall. There is a female specimen in the Cornell University col- lection from Truro, Nova Scotia, of the second species which I cannot distinguish from my European specimen. Walker (List, IV) described three species from Canada, which Stein, with a slight doubt in each case, considers synonymous with sylvestris. A study of the descriptions reveals but trifling differences. 320 ENTOMOLOGICAL NEWS. [ July, 17 LISPOCEPHALA. The species of this anomalous genus were formerly group- ed with Coenosia to which they bear a striking resemblance in the arrangement of the sterno-pleural setae, setae of the posterior tibiae, wing venation, and in the spotted abdomen. The genus ts now placed among the Limmnophorinae. - The front is broad in both sexes as in Lispa, and the fulcrum ot the hypopygium of the male is directed forward. The spe- cies thus far known to occur in the United States may be separated as follows. a. Crossvein not clouded. b. Middle tibia with a bristle on the anterior side; costal spine pres- ent; wing with a brownish tinge. Ohio, New Hampshire, verna Fabr. bb. Middle tibia with no seta on the anterior side; costal spine not distinct. c. Wing of the male milky white. Many localities in the United States....erythrocera R. D. (= lacteipennis Zett. IV, 1722). ce. Wing of the male grayish hyaline. Massachusetts, var. of erythrocera ? aa. Crossveins clouded; middle tibia with no seta on the anterior side. @ronos Maines ee es-ceeriee alma Meigen, var. pallipalpis Zett. (b). There is another lacteipennis Zett. (1V. 1586), a species not yet recorded from the United States, which should not be confused with L. erythrocera (= lacteipennis Zett., 1V. 1722). The former species is now placed in Deviopsis, a Coenosine genus. Specimens of L. alma were taken at Orono, Maine, in October. I have referred these specimens to var. pallipalpis Zett. (b) because the abdomen is but faintly translucent at the base and at the apical margins of the first and second segments. Limnophora torreyae Joh. In the original description of this species a misprint occurs. The post sutural d.c. setae are four and not three in number. In some specimens the orbits are not quite contiguous, being separated by a slender frontal line. Mydaea pectinata Joh. In the original description of this species, fourth line from the top. page 393, substitute for the words “tibia with a row” the words “tibia with an irregular double row.” per» Se ~~ Vol. xxviii] ENTOMOLOGICAL NEWS. 327 Phaonia nigricans Joh. The genus Phaonia, as at present defined by recent European workers, is distinguished from Mydaea by the presence of a seta on the posterior median extensor surface. If this inter- pretation be adopted the specific name noted above which I assigned to one of our New York species need cause no con- fusion. If, however, the emphasis be placed upon the presence or absence of the pilosity of the eyes, redistributing the species into the two groups corresponding to the genera Hvetodesia and Spilogaster, then the name nigricans becomes a homonym, having been assigned to another species by Stein in 1897. For the benefit of those who prefer the latter group- ing of species I suggest that the name cayugae be adopted to replace my nigricans. An additional locality record for this species is McLean, Tompkins County, New York. Dialyta flavitibia Joh. &@ —Like the female except that it is a trifle smaller (6 mm.); the front is about as wide as one eye, somewhat narrowing at the base of the antennae; buccae narrower and antennae longer and broader than in the female; orbits about half as wide as the frontal stripe at the lower ocellus. Abdominal setae longer and stouter than in the female; five pairs of marginal setae on each of segments two and three and six pairs on the fourth, five pairs of discals on the third and fourth segments; all sternites visible. Femoral setae stronger and more nu- merous; tibial setae as in the female except that those of the hind legs on the outer lateral flexor side are more uniform in size. Crossveins only faintly tinged; one large costal spine; R 4+5 more arched up- ward. The hypopygium somewhat resembles that of D. atriceps as figured by Schnabl and Dziedzicki (Pl. 21, figs. 555, 556). In our species, however, the fulcrum has, in addition to the laterals, a small median tubercle on the ventral side; the inferior forcens are stouter, and the superior forceps are quite different, being deeply cleft, re- sembling those shown in fig. 493 (PI. 19), but with the median angles rounded, not produced. The fifth sternite differs but little from that figured for D. atriceps. This specimen was taken at Danbury, Connecticut, in June, and sent to me by Mr. C. W. Johnson. There is a female specimen in the Cornel! Collection from Ohio, and Mr. John- son writes me that the species also occurs in Pennsylvania and Ontario. 328 ENTOMOLOGICAL NEWS. [ July, 17 New Species of Lepidoptera. By HENRY SKINNER. Argynnis californica n. sp. 3g. This species is paler in color than its related forms and has a faded or washed out appearance in comparison with its relatives. In size it is smaller than snyderi which it resembles in markings. It is about the same size as calippe Bd. and juba Bd. but is larger than coroms Behr. It can be at once separated from calippe by its much lighter color and from juba by the much duller color of the buff band on the underside of the secondaries. Both sexes are heavily silvered beneath. 2. Quite similar to the male in color and markings. The male expands 56 mm. and the female 58 mm. Described from fifteen specimens from California, the type and paratypes were taken by Mr. J. G. Grundel at Alma, Santa Clara County. I would not have ventured describing this species without a good figure if it had not been already well figured by Mr. W. H. Edwards under the name coronis, in his Butterflies of North America, vol. 3, pl. 4 of Argynnis. A number of years ago I compared specimens of my own with the type of coronis Behr in the Strecker collection. Due to Mr. Edwards’ figure of this species it has been accepted as coronis and snyderi, a related species, has been considered by some persons a variety of coronis. The true coronts is very close to juba and calippe. Melitaea arida n. sp. Upperside. Primaries dull fulvous marked with a series of small spots crossing the wing from the costa to the interior margin. The submarginal row is almost obsolete, the central spot being a crescent; the next row consists of three larger spots beyond the cell and two below, the last one small and hour-glass in shape; the last row con~ sists of one spot near the end of the discal cell and one spot directly below it. Secondaries same color as primaries with three rows of spots crossing the wing from the costa to the interior margin. The sub- marginal row consists of seven, narrow, minute yellowish crescents; the next row is composed of six minute black spots edged on the inner side by dull yellow; the next row is a curved line of minute yellowish spots; there is a yellow linear spot in the cell. Underside. The primaries have a marginal border composed of brown and yellowish spots; the limbal area is marked by spots of two shades of fulvous. The secondaries have a submarginal row of crescents, two near the costa and one at the lower third; the next row consists of five small black dots, the lower one very minute; the basal area is made up of several rows of spots semi-silvered. Expanse 26-30 mm. Type and paratype. Two specimens marked Cochise Co., * Vol. xxviii] ENTOMOLOGICAL NEWS. 329 Arizona, May. Received from Mr. F. Haimbach without more definite locality. This species is close to vesta Edw. but the markings are much fainter and different in color, those of vesta being orange-fulvous. The characteristic row of orange fulvous spots so conspicuous in vesta is replaced in arida by a faint line of spots. The silvered spots on the underside of the second- aries are also characteristic. Erythroecia hebardi n. sp. In volume nine of Sir George Hampson’s Catalogue of the Lepidoptera Phalaenae, p. 57, there is erected the new genus Erythroecia with the type species swazvis H. Edwards. He de- scribes a new species under the name rhodophora which is figured on plate 138, no. 4. The type locality given is Capitillo, Guatemala. Last summer Mr. Morgan Hebard captured a species of Erythroecia at Hot Springs, Virginia, August 15th, at light, two perfect male specimens. This appears to be a much more robust species than rhodophora and the primaries are much more obscured by red (crimson) and the ground color of the wings is yellow, almost orange. The orbicular and reniform do not show as in Hampson’s figure. The Virginia species expands 34 mm. It is possible that this may be a very good species, a topo- morph or only a variety of rhodophora but additional material is needed to establish their true relationship. If they are the same species the distribution as at present known appears very strange. Autographa olivacea n. sp. @. Head and thorax gray mixed with white hairs; tegulae gray; thoracic crest gray-white at tips; abdomen and legs gray; crests brown tipped with gray. Fore wing grey tinged with whitish olive, the medial area below the cell shining dark olive, extending from the apex and covering the outer third of the wing and extending two-thirds the distance to the inner margin; orbicular faintly indicated and not silvered; a very small silver stigma, linear and having a faint incurved point at the outer end; hind wing with a greenish tinge. Expanse 39 mm. Type one specimen sent to me by Mr. Eugene O. Mur- mann, taken at Los Angeles, California, August, 1916. This species resembles ampla Walk. but may be readily differentiated by the olive shade of the outer half of the primary wing. The types of these species are in the collection of The Academy of Natural Sciences of Philadelphia. ENTOMOLOGICAL NEWS. PHILADELPHIA, PA., JULY, I917: Insects and War. Unfortunately the lessons of the past have not been sufficient- ly taken to ‘heart and at the present time we are confronted with the grim destroyer in many forms. Every soldier thinks he will be one of the fortunate individuals and escape some death- dealing missile, but he is much more likely to be the victim of some low and minute form of either animal or vegetable or- ganism. In spite of the great advance of modern science and knowl- edge gained, its practical application is relatively very defec- tive and inefficient. The mind of the medical profession runs largely to therapeutics—the application of drugs to the cure of disease, but unfortunately remedial measures can’t compare in value with preventive medicine. The sick soldier is a distinct loss as a fighting unit and is a menace and expense to the Government as he needs hospitals, doctors, nurses and medicines. A few references to the past may enlighten the thoughtful. During the Civil War, on the Union side, 93,369 soldiers were killed and 186,216 died from disease. In the Crimean War 4,602 were killed and 17,580 died victims of disease. A re- markable example of mortality from disease and low death rate from wounds is shown by the figures from the French Expedition to Madagascar in 1894, 29 being killed and 7,000 dying from disease. In the Spanish-American War only 454 Americans were killed and 5,277 died from disease, mostly typhoid fever carried by house-flies. A more specific instance of disease morbidity and mortality is shown by what happened to the First Pennsylvania Infantry in 1898. There were 792 men in the regiment and 169 cases of typhoid fever and twelve deaths. In many of the camps in this country and Cuba men were compelled to walk through human excrement to get to the latrines, and the food in the mess tents was black with flies. The mouths of the sick soldiers in the hospitals and hospital 330 Vol. xxviii] ENTOMOLOGICAL NEWS. Bat tents could not be seen for house-flies, and these insects were sucking the juices from the lips of unconscious soldiers and many of these sick men were brought to Philadelphia by the car-load. Insects are responsible entirely or in large part for the trans- mission of typhoid fever, typhus fever, malaria, yellow fever and tuberculosis and many lesser forms of disease. Strange to say, the persons most keenly alive to these condi- tions and the persons who are meeting and trying to prevent these things are the mothers of the young men being trained for war. So far as we are aware the Government has done very little to prevent a recurrence of this dreadful sacrifice of life. There will be plenty of medical men to look after the small ills incident to camp life, but will the expert and capable men be there to guard against disease? It has been suggested that a medical entomologist should be stationed at each concentration camp, a most important matter, as sanitation and preventive jeasures greatly exceed drug therapeutics in importance. We sincerely hope that the present war will not show the dread- ful mortality from disease exhibited in the wars of the past.— FlENRY SKINNER. The second report of the Emergency Entomological Service of the United States Department of Agriculture, to which we called atten- tion in the News for June, page 283, has appeared, dated June 1, 1917, in I9 mimeographed pages. It announces the establishment, as an emer- gency measure, of a distinct section or branch of the Bureau of En- tomology, that of “Stored Product Insect Investigations,’ of which Dr. E. A. Back has been put in charge. Plans for the use of the Boy Scout organization to report insect injuries and to spray infested small gardens are being developed. There are reports of insect injuries as in the first report; 314 pages are devoted to a consideration of the “acute situation [which] appears to exist as to the supply of arsenical insecticides in this country.” It is stated that “The Council of Na- tional Defense is still considering the plans for the utilization of entomologists in the war. The present plan of the Council provides for a corps of entomologists to be coordinate with the corps of sani- tarians. This subject is also being considered by the Chief of Bureau and the Surgeon General of the Army Medical Corps.” B22 ENTOMOLOGICAL NEWS. [July, 17 Entomological Literature. COMPILED BY E. T.

[We have brought together, from various sources, published during the last year, the following data on entomologists who have recently passed away.] A brief note in Science for February 2, 1911 (page I12) announced the death of Juan J. Ropricuez, of Guatemala City, on December 22, 1916. Thanks to Mr. William Schaus, we have received a typewritten copy of an obituary notice in El Diario de Centro-América (Guatemala), for December 22, 1916, from which we translate the following: Don Juan J. Rodriguez Luna, who was born in 1840 and who consequently died at the advanced age of 76 years, had shown already in his early youth his love for this class of studies [zoology] and his competence in dealing with them. As was the custom in that period, he began his education in the College of the Seminary and has left us interesting notes of the awakening of his scientific inclinations. In the Semi- nary there existed no provision for the natural sciences, but he already observed with attention the life of insects, their metamorphoses and habits, and toward the end of his stay in the college, Father Parias, to stimulate his inclinations, lent him a very elementary book from the library. Another Father, notwithstanding, counselled him not to devote much time to this occupation because “he who looks much at the earth does not look to heaven.’ This did not hinder the young lover of nature from continuing his studies, which must have been well advanced in 1864, when the Sociedad I Shee doptera from Peru.
