It is. a well-known fact that insect tissue is aerobic, /. c, tubes called trachea; ramify the entire body and supply air directly to the cells. There is no medium, like the mammalian erythrocytes, which transfers the oxygen from the lungs to the tissues. During the course of some work on the cultivation of insect blood cells in vitro. I made some observations that clearly showed insect tissue to be dependent upon direct air. Since the method could be very nicely used in entomological class demonstration work, I thought it well to present the observations. The method for preparing tissue- culture slides is familiar to all biologists, so I will not dwell on very many of the technical details.^ Suffice it to say, that I used depres- sion slides with thin No. o cover slips so that I could work effectively with the oil immersion lens. Both army worm (Cirphis nnipuncta) and gipsy moth caterpillar {Porthctria dispar) blood was found suit- able for the experiments. All work must be done under sterile conditions. The animals to be operated upon are held in one hand and bent back so that the ven- tral side can be washed off with alcohol. When this evaporates, the tip of a proleg is then quickly cut oft' with sterile sc'ssors and the drop 1 Those interested in the cultivation of insect tissue are referred to: R. ^^^ Glaser, " The Growth of Insect Blood Cells i>i vitro." Psyche, Vol. XXIV, Xo. I, 1917. 1 2 Journal New York Entomological Society, [^'o'- >^>^\'I- of blood which oozes forth is caught on a sterile cover slip. The cover slip is then placed over a sterile depression slide, and the edges are sealed with melted vaseline. Insect blood cells grow^ very well in their own plasma, but Locke's solution can be added if desired. Locke's solution is isotonic with insect tissue, but has no particular advantage except that its addition thins out the plasma and produces a greater transparency in the prep- arations. If we carefully place the drop of blood in the center of the cover slip the cells grow very slowly. Many disintegrate entirely, and others do not show any visible growth for two or three weeks. ' Even the^i no large syncj-tial masses are formed, and sooner or later, as soon as the supply of oxygen in the depression slide is diminished, begin to disorganize. At first I supposed that the death of the cells was due to the exhaustion of the required nutrition, but such was not the case. Insect blood cells can be kept alive for a surprisingly long time with- out the addition of fresh media. If the preparation, in which the cells are disintegrating, is shaken a bit so that the drop of blood flows over along the edges of the cover slip a change will soon become ap- parent. On reexamination after about two or three weeks the cells lying in close proximity to the vaseline will appear healthy, and beau- tiful large syncytial masses will be found. In order to be certain that the vaseline was not giving off some- thing which stimulated the cells to grow, the following experiments were performed : Blood was placed in the center of the cover slips and a small piece of sterile vaseline added to each drop. Six such slides were prepared, but I failed to notice any large syncytial masses even after six weeks. The preparations were then shaken so that the blood flowed over along the edges of the cover slips and in two to three weeks more the syncytial masses were obtained. We can conclude from these observations that direct air is abso- lutely necessary for the growth of insect tissue. The blood cells kept in the center of the cover glass soon exhaust the oxygen present and cease to grow. However, if they are brought in contact with the vaseline through which the air undoubtedly filters, they become reju- venated and form syncytia. Of course air filters through the vaseline also when the cells are confined to the center of the cover slip. Init it is not so readily nor so rapidly obtained l)y the cells. The latter are March, 19 iS- J WaTSON : BUTTERFLIES OBSERVED IN OnE DaY. 3 highly metabolic and require oxygen very rapidly. My contentions were further proven by preparing slides and sealing the edges of the cover slips with a thick ring of paraffin. The blood was made to flow over along the edges as usual, but no syncytial tissue-like masses were formed. Apparently the air was unable to filter through this thick layer of paraffin. A drop of blood permitted to remain in the center of the cover slip usually will assume a light yellow or light brown color. How- ever, if the preparation is manipulated in such a way as to permit the drop of blood to come in contact with the edges of the cover-slip it rapidly turns black in color. This is due to the fact that the air filters through the vaseline and the tyrosinase present in insect blood oxidizes the colorless tyrosine producing a dark pig-ment. A LARGE NUMBER OF SPECIES OF BUTTERFLIES OBSERVED IN ONE DAY'S COLLECTING. By Frank E. Watson, New York, N. Y. This paper might be entitled Butterflies of Fort Montgomery, as it deals exclusively with those observed at that locality, except that no attempt has been made to list all the species known to occur there. The writer simply wishes to bring out what he believes to be an ex- traordinary number of forms observed on the wing in one day in a single locality. Fort ^Montgomery, Orange Co., N. Y., is a small historic town situated on the west bank of the Hudson River, some five miles south of West Point and al)out forty-three miles, on an air line, north of New York City. It is practically in the heart of the Highlands, with Anthony's Nose looming up on the opposite shore and Bear Moun- tain a mile or two to the west.^ The region is well watered and rather rugged; the hills are steep and attain an average altitude of about 1,200 feet; the vegetation is rich and diversified. The collecting 1 Those interested should consult the U. S. Topographical Maps — West Point and Schunemunk Quadrangles. 4 Journal New York Entomological Society. tVoi. xxvi. is naturally excellent and this, together with the charming scenery, makes a day spent there of great delight to the naturalist. It would not be fair to speak of Fort Montgomery without a word of thanks to Mr, Wm. T. Dav.is, the first of our local entomologists to collect there and the one who induced the writer, among others, to visit the region. On July I, 1906, Messrs. Gaylord C. Hall, Harvey Mitchell and the writer journeyed to Fort Montgomery via the West Shore R. R. and arrived about 9 A. M. We followed the road running west to The Torne, taking the left-hand fork which traverses the region back of Bear Mountain. We collected mostly on the road but the adjacent fields, meadows and open places were also examined. It was a clear, beautiful day, just nicely hot for butterflies, and they were in great abundance. Papilionid-E.- Papilio polyxenes asterius Cramer.=^ Papilio glaucus glaucus Linne. Common about the wet spots along the road and also on dung. Papilio troilus troilus Linne. Very common, under the same con- ditions as the preceding species and often in company with it. Papilio marcellus Cramer. A single specimen was seen by Mr. Mitchell feeding at a damp place in the road, in company with glaucus and troilus; it immediately took wing and, although followed some distance down the road, it escaped by flying into the thick woods. PlERID.E. Pieris rapae (Linne). Common everywhere. Eurymus philodice (Godart). Connnon. Danaid.e. Danaus archippus (Fabricius). Satyrid.e. Enodia portlandia (Fabricius). About five or six specimens were seen. They may be found on dung or damp spots along roads. 2 For convenience the Check List of Barnes and McDunnough is here followed. 3 Nomenclature after Rothschild and Jordan.

March, igiS.] WaTSON : BUTTERFLIES OBSERVED IN OnE DaY. 7 I believe that there were fifty, possiljly one or two more, species flying on this day and that, with a little more luck, the list would have reached the half-hundred mark. The following notes will, I think, bear out my contention. On July 4. of the preceding year, the writer took lb flown spec- imens of Mitoura damoii damon (Cramer) at the same locality. As we did not have time to visit that section of the territory where the dainoii were previously taken and where there is a station of red- cedar trees, we may have missed this species. It is possible, of course, that 1906 was not a damon year. On July 4, 1906, or three days later than the date of the above list, I again visited the same region. It was expected that even a larger number of forms would be recorded but in this I was disappointed. The day was clear and fine but for some reason butterflies were not so numerous as they were on July i and only thirty-nine species and one variety w^ere noted. The varietal form being a single worn specimen of Poanes lioboiiiok form pocahontas (Scudder). This species, as is well known, is most common during early June. Two old specimens of this dimorphic form were also observed by me at this locality on June 24 of the same year, so that it was certainly flying on July i although not observed by us. Three additional species which were captured on the July 4 trip were : Fcniseca tarquinius (Fabricius), two specimens, somewhat flown, one of which alighted on my hand and fed on the perspiration; Strymon acadica (Edwards), several individuals, somewhat worn; and Enphyes conspicua (Ed- wards) = pontiac (Edwards), two specimens, condition not noted. Of these three species, tarquinius and acadica were surely flying on July I and more than likely conspicua was as well. It was with considerable reluctance that we quit such good col- lecting, about 4 P. M., in order to catch our train. The forty-four species were, therefore, collected in about six and one half hours (allowing half an hour for lunch) and probably over less than five miles of territorv. Journal New York Entomological Society, t^'"'- >^-^\'i' MICROCLYTUS— A CORRECTION. By Charles W. Leng, Staten Island, N. Y. According to the Classification of the Coleoptera of North Amer- ica (S. M. C. no. 507, 1883), the genus Microclytiis has the following characters, viz. : second joint of antennae equal to fourth, antennae not spinose. The type of the genus is Cyrtophonts gazellula Hald., and it is pointed out, p. 305, that it has the form and coloration of the European Anaglyptus mysticus but differs " essentially by the second joint of the antennae being fully half as long as the third and scarcely shorter than the fourth joint." In 1887 I noticed that in my two specimens of Microclytus from Canada the antennre were not as described in the Classification but had the second joint short as usual in the Anaglypti. The discrepancy was discussed with Dr. George H. Horn, in whose collection were two specimens from Ohio like those on which the Classification was based, and we concluded that the difference was a sexual matter, and exchanged specimens so that each should have both sexes. The amended key to the genera of Anaglypti (Ent. i\m., II, 1887, p. 195) and the treatment of the species of Microclyfits (Ent. Am., III. 1888, p. 23) by which M. gibhuhis and M. nigcr of Leconte were sunk in synonymy, were based upon the theory that they were identical with -1/. gazcUula Hald. in which species the antennte dift'ered in the sexes. I regret to say that this appears now to have been entirely wrong, for recently ]Mr. Frank Morris, of Peterborough, Ontario, has called my attention to a considerable number of specimens of Microclytiis that he has caught on the blossom of choke-cherry in which the sec- ond joint of the antennae is only half the length of the fourth joint in both sexes, thus disproving the supposed sexual character of the dis- crepancy noted thirty years ago. The antennae in the specimens as- sumed to be males are nearly as long as the body, while in those assumed to be females they barely attain the middle band of the elytra. In both cases the antennae bear the same long hairs that are to be noted in M. gazcUnla, and to which Casey has called attention (Mem- oirs, III, p. 375) as characteristic of the genus. The specimens sent March, i9i8.] LeNG : AIlCROCLYTUS. 9 by 'Sir. Morris differ liowever from .1/. yaacllula in the relative length of the antennal joints and represent apparently the gibbulus of Le- conte erroneously sunk in synonymy. In seeking a name for these specimens of Microclytiis one has to choose between gibbulus Lee, niger Lee, insinuans. Csy., frosti Csy., and comprcssicollis Gory. Of these niger Lee. may be discarded as a clerical error because in the Melsheimer Catalogue, 1853, appears " Cyrtophonis gibbulus Lee. (Clytus) L. Sup. 234; niger Lee. (err: cler.) J. Acad. 2^ 2. 20." Li regard to compressicollis Gory the de- scription (copy of which I owe to the kindness of Mr. H. S. Barber) reads: "Niger; thoracis medio elevato; elytris basi gil^bis postice dimidio obscuris ; pedibus rubris. Long. 4 lig. Larg. i lig. Noir et pubescent. Corselet elcve au milieu, comprime sur les cotes, avec un point brun. Elytres d'un brun rouge, elevees a la base, avec deux traits oblique cendres, un semblable transversal vers le milieu, suivi d'une tache noire. Extremite obscure, couvertes de polls cen- dres. Dessous du corps et pattes d'un brun rouge. Premier article de I'abdomen avec le bord posterieur noirs, et une tache blanche de chaque cote; les autres articles noirs ainsi que les jambes." It seems to me impossible, with no mention of the antennae, to say whether this description antedates that of ga::ellula or of gibbulus. Aurivillius in the Junk Catalogue includes both the latter as synonyms of comprcs- sicollis, but as they are not identical, his course cannot be followed. Casey's description of insinuans was written under the belief (pre- sumably) that gibbulus was actually a synonym of gacelliila as had been published and appears to cover the Ontario specimens which we now consider as representing gibbulus. His description of frosti ap- pears to cover at best but a race of insinuans occurring in Maine. I have not seen the types and my opinion is based upon the descriptions and the following specimens; which illustrate the distribution of the genus : Two .1/. gazellula, St. Vincent, Pa., and Wilmerding, Pa., in collection of V. J. Zahrobsky. Two M. gazellula, Ohio, in my own collection. One .1/. gazellula, Pa., in collection of Chas. Schaeffer, all of which are apparently females. Six ,1/. gibbulus, Peterborough, Ont., in collection of Frank Morris. Four M. insinuans, Adirondack ]\Its., N. Y. in collection of Howard Notman. 10 Journal New York Entomological Society. tVoi. xxvi. 3 ^1/. frosti, IMaine. in my own collection. I M. gasellnla ^ (as formerly identified), Canada, in my own col- lection. Both sexes are represented in the specimens of gihhiiliis and its syn- • onyms. IMr. Morris states that he has seen a specimen of true gaccUiila from Canada. Dr. Hamilton in his Catalogue of the Coleoptera of Southwestern Pennsylvania says gazcUula is rare at Allegheny, Pa., but common at St. Vincent, and Henry G. Klages in his supplement thereto (Ann. Carn. Mus., I, 1901, p. 290) adds gihhulus "believed to be a distinct species by Dr. Hamilton." It seems therefore impossible to consider gazcllnla and gibbulus as geographic races of one species, since there is evidence that their ranges overlap. The bibliography and synonymy should stand as follows : Microclytus gazellula Hakl, Trans. Am. Phil, X. 1847, P- 4^ {gazel- luta err. typ.) ; Proc. Ac. Phil.. IV, 1847, P- 37-5 Lacard. Gen.

I am not unaware that Aurivillius treats the genus Microclytus as a synonym of Anaglyptns; but in this he stands opposed to all Amer- ican authors, Leconte, Horn, Hamilton, Casey and Schaeffer, who has quite recently (Journ. N. Y. Ent. Soc, XII, 1904, p. 223) given a key to the genera of Anaglypti ; and his course cannot therefore be adopted. March, I9i8.] LeNG : A Nf.W PiEZOCORYNUS. 11 DESCRIPTION OF A NEW SPECIES OF PIEZOCORYNUS. By Charles W. Leng, New York, N. Y. Piezocorynus virginicus new species. Oblong, thorax narrower in front, as wide as the elytra at base, sides straight and oblique, body rounded behind with parallel sides ; dark brown, legs and antenna; with paler bands, pubescence irregularly condensed in pale spots especially towards sides of elytra. Head nearly black, finely confluently punctured, punctures forming fine transverse rugae on the occiput ; irregularly and sparsely clothed with short yellow hairs. Antenna shorter than the body in the female (male not seen), slender with a loose, three-jointed, flattened club; basal joint short and stout, pale; second joint longer, elongate, conical; joints three to seven very slender but each thickened apically ; joint eight elongate, triangular; joints nine to eleven wider and fringed with hairs, nine strongly triangular, black, emarginate at apex, ten wider than long, black, obliquely emarginate at apex, eleven elongate-oval, pale. The joints two to eight are each paler apically. Thorax as long as its basal width, tapering obliquely to about half as wide at apex, finely granulate, the basal ridge finely elevated, forming an acute angle at its extremities with the acute lateral margin, which extends nearly to the apex ; disk without elevations or channels; a few yellow hairs are seen above, sometimes feebly condensed into spots, more at the sides, and enough beneath to clothe the surface fairly thickly. Elytra parallel, with rows of distant punctures, punctuation how- ever obscured by dense pubescence, of which the yellow hairs are usually concentrated at the sides and apex, leaving the disk darker. The elytra are conjointly rounded at apex. Body beneath and abdomen clothed rather sparsely with pale hairs. Length 3.25-5.00 mm. Btickingham county, near Wingina, Virginia. Described from fifteen specimens collected by Col. Wirt Rol)inson, July 12, 1917, ovipositing on a recently killed black oak, and four specimens collected from the same tree by Wm. T. Davis. This species resembles P. dispar in the oblique emargination of the joints of the antenna! clul), but differs in the more strongly tri- angular form of the joints of the club and in their marginal hairs. It also lacks the thoracic elevations of dispar; the yellow pubescence of the elytra is differently arranged, being concentrated on the disk in dispar, on the sides in z'irgiiiiciis. ^Tr. Davis has pointed out further 12 Journal New York Entomological Society. [^'"'- >^>^v^- than ill ilispar and nurstiis all the tibiie are annulated near the middle, while in virginicns the annulations are nearer the base of each tibia and more irregular in form, some of the paler hairs extending to the basal part of the tibit on its inner side. From })iixtiis and ma^stus, P. z'irgi>nciis differs so greatly in the form of antennae that there is no risk of confusion. The anteimie of P. dispar ^ are one half longer than body (not one half the length of the body as erroneously stated in " Rhynchophora of N. E. Amer- ica") and it is possible that the male of virgiuicus has also antennae longer than the body. NOTES ON THE OVIPOSITION OF SOME SEMI- AQUATIC HEMIPTERA (HEBRUS, SALDA, LAMPROCANTHIA). By H. B. Hungerford, Lawrence, Kansas. In 191 1 the late Doctor Heidemann published "Some Remarks on the Eggs of North American Species of Hemiptera Heteroptera,"^ in which he listed the eggs of the Hebrids, Saldidce and Mesoveliidse as unknown. Since that time Renter in his " Neue Beitrage zur Phylogenie und Systematik der Meriden, nebst einleitenden Bemer- kungen fiber die Phylogenie der heteropteren Familien, 1910" at- tempted to show the phylogenetic relationships of the families of heter- optera. In 1912 he modified his system in the light of added evidence. It is in his '' Bemerkungen fiber mein neues Heteropteran System, 1912" that he quotes Bergroth to the effect that Bueno had examined the egg of Mesovelia and established its great similarity to the Na- bidae. Since that time the writer has figured and described the egg of Mesovelia mulsanti, White. In reviewing Kirkaldy's splendid papers on British water bugs, 1894-1908, Wesenberg-Lund's " Fortpflanzungsverhaltnisse : Paarung und Eiablage der Siisswasserinsekten," as well as such texts as Bade, '09, Brauer, '09, Ulmer, '11, and Brocher, '13, it would appear that the egg stages of Hebrids and Saldids are as vet unnoted. 1 Proceedings Ent.
