SLINGERLAND, CORNELL UNIVERSITY, ITHACA, N. Y. September 3rd, 1895, I received several nearly full-grown specimens of the curious, sluglike caterpillars of this beautiful moth, so aptly named by Professor Comstock, “the crinkled flannel moth.” The cunning brown caterpillars were placed in a cage here at the insectary, where they fed freely on apple leaves, although they were feeding on quince when found at Worcester, Mass. Since Dr. Packard described the insect in its different stages in 1864, its life-history has been worked out in detail by Dr. Lintner (Ent. Contrib., II., p.: 138, 1870), and recently by Dr. Packard (Proc. Am. Phil. Soc. for 1894, p. 275). In this last paper Dr. Packard has described and figured in detail the extra two pairs of abdominal legs (seven pairs in all) possessed by the caterpillars, and some curious lateral glandular processes. It is now our practice here at the insectary to photograph, so far as possible, every stage, phase, and habit of any insect that we may study. It is not often, however, that we have as good a subject as the crinkled flannel moth proved to be. The main object of this note is to introduce some of the lifelike pictures we were able to secure of this interesting and beautiful insect. As shown at @on the plate, three of the cunning little caterpillars posed for their photograph, which represents their natural size and brings out their characteristic appearance much better than any other figures we have seen. They spun their tough brown cocoons (represented natural size at aon the plate), with the tightly fitting and ingenious door at one end, on September sth. Upon prying open the door of one cocoon, the male pupa (shown natural size at 4 on the plate) was revealed. As the cage was kept in our warm office, the development of the insect was doubtless abnormally accelerated, for on December 21st and 24th the pupze pushed open the little doors, worked their way nearly out of the cocoon, and the moths emerged. We aimed our ‘“‘ Premo” at one of the - THE CANADIAN ENTOMOLOGIST. male moths as it was resting quietly and naturally on the muslin cover of the cage, with the result as shown at con the plate. We were some- what loath to kill such a pretty, daintily bedecked creature, but well, he now fills an honoured place in our collection here at the University. Figure ¢ on the plate well represents this pretty creature (twice natural size) as he now looks in the collection. Imagine the lighter portions of the figure to be of a delicate straw-yellow colour: and the darker waves and crinkles of a rich brown shade, and you have a faint conception of this crinkled flannel moth. I do not know that the insect has ever done enough damage to make it of economic importance. It certainly has a wide range of food plants, as shown by Mr. Beutenmiller (Ent. Americana, III., 180), who lists twenty-five different plants, and the cranberry has since been added in Massachusetts. Briefly stated, its life-history seems to be as follows: The eggs are laid about July 1, and hatch in a week or ten days; the caterpillars feed during July and August, pupating in September ; some of the moths may emerge in the fall, but doubtless most of them hibernate as pupe, the moths appearing in June and some laying their eggs. TORONTO BRANCH OF THE ENTOMOLOGICAL SOCIETY OF ONTARIO. It is with much gratification that we announce the formation of a branch of our Society in Toronto. In the month of February last a number of entomologists in Toronto, feeling their isolation and need of co-operation, met together and decided to form an organization for the promotion of the study of entomology. They accordingly established ‘The Toronto Entomological Society,” with Mr. E. V. Rippon as President, and Mr. Arthur Gibson, Secretary. Regular meetings have been held on the first and third Fridays of each month, and recently a room has been engaged at 451 Parliament Street, where the books and collections are kept and the meetings held, and which is open at all times for the use of the members. For the last ten months the Society has been very successful and its members full of enthusiasm; much satis- factory work has been accomplished, and great pleasure has been derived by the members from meeting with kindred spirits, comparing specimens, discussing questions that arise from time to time, and giving and receiv- ing much assistance in many ways. Recently the desirability of affiliating with the old-established Ento- mological Society of Ontario was brought before the members, and after © THE CANADIAN ENTOMOLOGIST. full deliberation it was decided to become incorporated with it as a “Branch,” in accordance with the terms of our Constitution. It will therefore be known,from the beginning of the New Year, as ‘“‘ The Toronto Branch of the Entomological Society of Ontario.” It is hoped that every one interested in entomology, living in Toronto or the neighbourhood, will join the “ Branch,” and thus become members of our Society. The next meeting will be held on Friday evening, January 8th, at 8 o’clock, when visitors will be heartily welcomed. The Montreal Branch has been in active operation for over twenty- three years, and held its zooth meeting a few months ago, We hope that in time to come the Toronto Branch may be able to boast of a similar record, and that each year as it goes by may find it growing and prospering, and doing good work for the furtherance of the science of entomology in the Dominion of Canada. BREPHOS MIDDENDORFI, Mev. On April 25th, 1896, I made a very lucky capture of a perfect speci- men of this rare and beautiful meth. The afternoon being sunshiny and warm —one of our first spring days —I had gone out to look for beetles in a piece of wood along the Red River, a few miles from the city. This locality had proved rich in Carabide in 1894, about the same date. Greatly to my disgust, I found the place transformed, all logs and ‘‘brush” having been cleared away the previous season, and hardly a beetle of any kind was to be found. The moth in questicn was first seen to alight on the bank of a cut- ting leading down to the river; when disturbed from there by my investi- gations as to its identity, it flew up and down the roadway for a little while, and then hovered about some patches of mud, occasionally resting on the mud in the sunshine, very much after the manner of some of our butterflies. By this time I had got near enough to it to discover that it was something quite new to me, and my desire to capture it was there- fore increased ten-fold. I had no net with me; in fact, I was only pro- vided with a rather narrow-necked cyanide bottle for Coleoptera (the neck of my bottle was not an inch in diameter). That I was able, after several futile attempts, to get the mouth of the bottle down over it as it sat in the road, without damaging it in any way, was a matter of surprise at the time and congratulation whenever I have thought of itsince. I certainly never made a more lucky capture. To Prof. John B. Smith I am indebted both for the identification and for his generosity in returning the specimen to me, A. W.

A. labrosa is cited from Niericd ie its descnuey but I have not seen it from that country. Mr. Robertson sends it to me from Illinois. There are two species found in Texas, which may be expected also across the THE CANADIAN ENTOMOLOGIST. 5 Mexican border. One of them is what passes for A. sumptuosa, Sm., in this country, and indeed agrees with Smith’s description; but Col. Bingham finds that a co-type in the British Museum belongs to Section A above (spur minutely ciliate), while our insect belongs to Sect. B. It is just possible that the B. M. co-type is not identical with the true type of sumptuosa ; if this is not so, our swmptuosa will have to be renamed. The other Texan species referred to was recorded by Cresson as A. lucidula, Sm., but it differs from that, and is referable to A. humeradis, Patton, of which it may perhaps constitute a geographical race. I have several specimens collected by Prof. C. H. T. Townsend at Beeville, Texas, Aug. 29, 1896, on a species of Composite. Col. Bingham’s studies at the British Museum show that 4. humeradis, which belongs to Sect. B, cannot be identical with A. fervida, Sm., as Robertson has supposed, since that belongs to Sect. A. Also, Patton was wrong in referring Zucidu/a, Sm., which belongs to Sect. B, to vériduda, Sm., which is of Sect. A. I will now describe the two new species indicated above :— Augochlora Binghami, n. sp. (subg. Augochlora, s. str.)—¢%. Length about 12 mm., brilliant bluish-green, the face a yellower green. Face nar- rowing below, eyes deeply emarginate ; sides of face with conspicuous, partly appressed, silky white pubescence ; cheeks with long white hairs. Clypeus, supraclypeal area and middle of vertex with sparse, inconspicuous black hairs. Clypeus rather prominent, subcancellate with very large close punctures, its anterior margin and the upper half of the labrum whitish, mandibles wholly dark. Vertex finely and very closely punctured. Antenne reaching to base of wings, piceous, flagellum obscurely rufescent beneath, last joint conspicuously hooked. Mesothorax shining, with very distinct rather small close punctures, much densest at the sides, where a minute cancellation results. Parapsidal grooves distinct. Prothoracic keel fairly strong. Enclosure of metathorax fairly well defined, irregularly wrinkled, its hind margia gently curved, not angled. Posterior truncation roughened, bounded below at sides by an acute ridge, which ascending rapidly fails. Pubescence of thorax sparse, grayish-white, black and inconspicuous on dorsum. ‘Tegule shining piceous, anteriorly whitish, basally green and punctured. Wings smoky-hyaline, apical margin darker, stigma dull testaceous, nervures fuscous, marginal cell miriutely appendiculate. Legs green with black tarsi, pubescence short and pale. Abdomen shining, closely punctured, hind margins of segments broadly 6 THE CANADIAN ENTOMOLOGIST. purplish-black. No hair-bands, but a very fine glittering pile all over, longer pale hairs at base of first segment, sparse black hairs on dorsum of hindmost segments and at tip. Punctuation of second segment con- spicuously closer than that of first. Venter piceous, first three segments with blue reflections. End of third segment with a large dark brown brush of hair, shaped like the tail of a fish; ¢. e. deeply emarginate, the sides diverging and ending in a point. Hab.—San Rafael, Vera Cruz, March 13, on flowers of plant No. 4, which is papilionaceous (C. H. T. Townsend). This beautiful species is named after Lt.-Col. Bingham, without whose notes on the British Museum types I should not have attempted this paper. Augochlora aurifera, n. sp. (subg. Augochlora, s. str.)— 2. Length about 74% mm, green; head and thorax dullish, rather a bluish-green ; abdomen shining, a yellower green, with the hind margins of the segments very narrowly coppery. Face fairly broad, emargination of eyes deep. Pubescence of head and thorax sparse and inconspicuous, dirty whitish, some black hairs on thoracic dorsum ; lower part of face in certain lights canescent. Clypeus with close punctures of unequal size, supracypeal area more finely punctured, vertex coarsely granular. Labrum and margin of clypeus black. Mandibles notched within, stout, rufescent medially. Glossa very long and narrow, coming to a fine point. An- tenne black, flagellum slightly rufescent beneath. Mesothorax very closely, finely, and uniformly punctured. Enclosure of metathorax con- spicuously longitudinally, or rather radiately, sulcatulate. Truncation shining, finely malleate, with a median groove. Tegulz shining piceous, the margin subhyaline. Wings smoky, stigma dull testaceous, nervures fuscous, marginal cell appendiculate. Legs piceous-black, with brownish pubescence ; only the anterior femora show any green. Abdomen shin- ing, with minute, not very close, punctures ; pubescence very sparse, no hair-bands. It requires a strong lens to see the abdominal punctures. Hfab.—San Rafael, Vera Cruz, March 9, on flowers of plant No. 6, referred by Dr. Rose to the genus JZe/opodium. ‘The hind legs, base of thorax and abdomen, and ventral surface of abdomen, carry considerable quantities of the orange pollen. Another specimen differs by being much bluer, the punctuation a little coarser, the stigma fuscous ; but it is evi- dently the same species. It is from San Rafael, March 14, on flowers of plant No. 5, a Vernonia. Both were collected by Prof. C. H, T. Town- send, ~J THE CANADIAN ENTOMOLOGIST. THE COLEOPTERA OF CANADA. BY H. F. WICKHAM, IOWA CITY, IOWA. XIX. THE CHRYSOMELID® OF ONTARIO AND (QUEBEC -— ( Continued ). Tripe 1X.—GALERUCINI. This tribes includes a number of species which are, asa rule, easily distinguished by the peculiar appearance given by their soft integuments and usually somewhat elongate form. ‘A number of them are pubescent, while others, on account of the peculiar sculpture of the surface, are quite opaque, the effect on the eye being, at first glance, the same in each case. The elytra in our species are longer than the abdomen, the prothorax is margined, the antenn approximate, inserted on the front, the hind legs with rather slender thighs, not fitted for leaping. It will be remembered in this connection that I consider the Halticini as a distinct tribe. Many of the Galerucini are extremely injurious, the striped cucum- ber beetle being well known and dreaded by gardeners ; its congener, Diabrotica longicornis, which has lately been found by Mr. Harrington in the Eastern Provinces, is a notorious pest to corn in the United States. In the Northeastern States the imported elm-leaf beetle, Galerucella xanthomelena, Schr., is doing much mischief, but I cannot find that it is reported from Canada. If found, it may be distinguished from all our other species of Gaderucel/a by the colour of the antennz, which are piceous above and fale beneath, while the elytra are comparatively finely and equally punctate. It is yellowish above, the head with one dark spot, the thorax with three, the elytra with a short inner stripe (sometimes wanting), and a long one from the humerus ; legs pale, each femur with a small dark spot. The tribe has recently been worked up in an excellent paper by Dr. Horn, and this has been closely followed and freeiy used in the prepa- ration of the following pages. In order to avoid the constant repetition of quotation marks and statements of acknowledgments, it is well to say that the differential characters brought out are in almost every case those used by the Doctor, and that while I have not scrupled to change the arrange- ment of his tables where it seemed to me more likely to serve the pur- pose of the present article, I have, on the other hand, found it impos- sible to improve on most of his expressions, and have therefore used them entire. With this acknowledgment of the source of whatever is good in the paper, we may proceed to separate the genera occurring in Canada, thus :— 8 THE CANADIAN ENTOMOLOGIST. A. Anterior coxal cavities open behind. b. Claws simple or bifid. c. Tibi without terminal spurs; epipleura of elytra extend- ing nearly to apices. d.

I have omitted Sce/olyperus from the above table, although the Southern Californian §S. macudicol/is, Lec., is in the Society list. The genus belongs in the group with open anterior coxal cavities, appen- diculate claws and well-defined epipleura. In the scheme it would — precede Luperodes, from which it differs in having no tibial spurs. The species above mentioned is about one-fourth of an inch in length, head and under surface black, thorax either yellow with three dark spots or entirely black, elytra bluish or greenish. Antenne two-thirds as long as the body, piceous, with three basal joints pale beneath. TRIRHABDA, Lec. Large insects, of rather elongate-oblong form, usually of somewhat opaque surface, the thorax in most cases spoited, the elytra bluish, greenish, or brownish, with yellowish stripes. They are to be taken during the summer months by sweeping rank herbage in lanes and meadows, and may often be taken in numbers on the golden-rod. Dr. Horn has thus separated our species : A.

GALERUCELLA, Crotch. This genus, as now understood, contains species formerly dis- tributed partially in Adimonia and partially in Galeruca. Many of them are quite common, and are to be found in the sweepings of meadows, on water lilies, Sagittarza, Eupatorium, or occasionally on the leaves of deciduous trees, as in the case of G. cavicoldis, which I have taken abundantly on wild cherry. All but three of the North American species have been recorded from Canada, and Dr. Horn’s table is here reproduced almost in full, though some portions are transposed, and the remainder made to include the non-vittate specimens of G. americana, so as to render identification a trifle more easy when reference cannot be had to detailed descriptions. The limit of variation in some of the vittate forms is very wide, and has resulted in the multiplication of nominal species. It is believed that the table will now cover any cases likely to be met with in the Provinces of Ontario and Quebec. In case of the occurrence there of the elm-leaf beetle, a reference to the first page of this article will result in its proper identification. A. Colour red.

CATALOGUE OF THE PHYTOPHAGOUS AND PARASITIC HYMENOPTERA OF VANCOUVER ISLAND. BY W. HAGUE HARRINGTON, F.R. S. C., OTTAWA. The following list is based upon a very interesting collection made, chiefly at Cedar Hill, near Victoria, by the Rev. G. W. Taylor, F.R.S.C., but includes such other species as I have found described, or recorded from Vancouver Island. Even with such additions it is a short list in comparison with those that could be compiled from much less extensive areas in Ontario. British Columbia has, as yet, had but few resident entomologists, and its rich fauna is, in consequence, but poorly known. Butterflies and beetles have been fairly well collected, but in other direc- tions there are almost unexplored fields for investigation. I have found but little literature relating to the Hymenoptera of Vancouver Island, and but scanty records of species captured there. Lord, in his interesting narrative of a Naturalist in British Columbia, has an appendix enumerating the insects secured by him, with descriptions of ~ a few new species. Cresson, in a paper entitled Descriptions of Ichneu- monide, chiefly from the Pacific Slope of the United States and British North America (Proc. Acad. Nat. Sci, Phil; Nov., 1878), described about twenty-five species from the Island, contained in the collections of the late distinguished entomologists, Mr. H. Edwards and Mr. Crotch. The late Abbé Provancher described a few species in the CANADIAN Entomotocist (Vol. XVII, p. 114), and in the Additions to his Petite Faune Entomologique du Canada credits the Island with some thirty-five species, mostly new forms contributed by Mr. Taylor and Mr. Fletcher. The types of some of those species are now in my collection, through Mr. Fletcher’s kindness, and have been found very useful for comparison, | : THE CANADIAN ENTOMOLOGIST. ay Kirby, in his List of the Hymenoptera in the British Museum, records several species of Tenthredinidze and Uroceride. To Mr. Taylor, how- ever, is due a large proportion of our knowledge of the Hymenopterous fauna. In Vol. XVI. and XVII. he published a list of eighty-one species, from the vicinity of Victoria, and he continued to collect there and sent specimens to Mr. Fletcher and myself until he carne to reside in Ottawa a few years ago. He then brought his collection with him to this city, and on his return to the Pacific Coast he placed all the remaining Hymen- optera in my hands, on the condition that I should prepare a list of them for publication, in revision and enlargement of his own earlier list, in which there are some errors in determination. The collection has proved to be a most interesting one, and to con- tain quite a number of new insects. It is, as might be expected, deficient in the smaller forms, such as Cynipide, Braconide, Chalcidide, and Proctotrypide. As time has permitted, I have proceeded with the determination of these insects, and have published descriptions (Can. Enr., Vol. XXVI.) of some new species, The Aculeata require further study, especially such genera as Andrena, Halictus, Osmia, etc., before a satisfactory list can be made of them. Mr. Taylor is now resident at Nanaimo, and it is to be hoped that his duties will afford him oppor- tunity to collect in that district. The publication of a list (even though imperfect) of the recorded species may perhaps stimulate others to join with him in a more systematic collection of the Hymenoptera of Van- couver Island, which offers so rich a field for study. The fauna is evidently a very extensive one, containing many species occurring in the Pacific States, while in the northern portion of the Island and on the mountains there should be a large intermingling of species inhabiting Alaska and the Rocky Mountains. It would not require much effort to increase many-fold the number of species at present known. The order Hymenoptera is so rich in species, and the conditions of the occurrence of the species are so varied, that it will long be possible to discover forms new to science, even in Ontario, where the fauna is so much better known. In the vast and diversified regions of the Pacific Slope, such new and undescribed species must be almost unlimited. TENTHREDINID&. Trichiosoma Taylori, Prov.—Common on the Island and throughout B.

Rules for regulating nomenclature with a view to secure a strict ap- plication of the law of priority in entomological work; compiled by Lord Walsingham and John Hartley Durrant (Merton rules). Longmans, Green & Co., London., New York, and Bombay ; 2nd Nov., 1896 ; 18 pages. Price sixpence. The rules are for the most part a good statement of current practice, with the suggestion of a considerable number of signs to facilitate brevity of reference without loss of accuracy. These may advantageously be adopted. Rules 7, 20, 21, 24, 25, 29 and 30 imply a much more rigidly classical attitude in regard to names than is prevalent in America. The authors would have all names according to the rules of Latin orthography, and would change those that are not, even so radically as gypsodactylus for cretidacty/us. Names with similar sound are rejected ; e. g., Ucetia invalidates Eusesia ; also those which involve a false proposition, or are offensive politically, morally, or by irreverence. Rule 12 defines publication as including the possibility of purchase. If the rule be not extended, it would invalidate all species published in - Government or private papers which are distributed without charge. The definition of a genus by designation of type without description is not referred to, and apparently is condemned by implication. The case of restriction of a heterotypical genus to one type by the successive removal of species to other genera by subsequent authors is _ not explicitly stated, and might well be added to rule 42. A few rules about the formation of family names might have been added, for example: 1. Family names shall be formed by adding —idz to the stem of some genus included in the family. 2. The generic name so used must be a valid one. 3. The first generic name used in a plural form shall be the one so used for the family type unless it be invalid, in which case the next generic name included in the family, which has been used in a plural sense, shall be substituted according to the rule of priority. Harrison G. Dyar, THE CANADIAN ENTOMOLOGIST. 23 MonocGrapu or tHe Bomeycine Morus: /. Votodontide ; by Alpheus S. Packard, M. D., National Academy of Sciences, Vol. VII. This magnificent work is, without doubt, an immense credit to the author, and will take a permanent place among the triumphs of American Lepidopterology. It is not my intention to discuss matters of general classification or nomenclature here. My reasons for differing on certain points as to the latter have all been given elsewhere, and the merits of the Comstock—Dyar classification have been insisted upon by Dr. Dyar. Dr. Packard’s work, as a whole, with its superb technical execution, has a value which could have been only enhanced by his attention to points of nomenclature, which I believe cannot be properly contradicted, and by his adhesion to a scheme of general classification, which I believe can- not be adequately gainsaid. I can here, out of my present limited knowledge, merely mention a few points, which may be of general or only of particular interest. There are a few errors in authorities. I do not know why my Vofodonta stragula and Schizura leptinoides and S. eximia are given to Grote and Robinson (plates). Nor do I know why my name is placed in brackets after Heterocampa Belfragei. 1 described the latter as a Heterocampa, and have no responsibility for its having been placed under Zztodonta, a reference which never occurred to me. I differ from Dr. Packard as to the validity of Zztodonta. The costa is straighter, the primary fuller outwardly over internal angle, apex sharper, while the antennal structure is decisive,.as compared with Hleterocampa subrotata; the orange spots are peculiar. . subrofata is a miniature obligua, and is placed next in my list. WZ. celtiphaga is founded on obscurely marked and small specimens, probably not different specifically. Litodonta may be amore specialized form, from the character of the female antenne ; the discovery of the larva will be attended with interest. The unhappy influence which Mr. Walker has exercised is very apparent, and the synonymy of Schizura ipomee exhibits this at its worst. I do not insist upon the validity of \S. fe/z?fer as a species; the black streaks are very distinct in both sexes and our nomenclature was invented to designate such forms, if not as species then as varieties. With regard to Hyparpax, and in connection with Dr. Packard’s remarks upon /. perophorotides, | again draw attention to my previous statements as to Abbot and Smith’s plate, that the figure of the female aurora at least approaches that form. ‘he late Mr, Hy. Edwards sent me at one time a damaged specimen (I think without head or feet) of a well-sized pink 24 THE CANADIAN ENTOMOLOGIST. and yellow moth from Colorado, resembling this genus or Axnisota rubicunda in colours. I would not describe it, but returned it as a proba- bly new Noctuid. The figure of EzAyparpax distantly recalls the speci- men, which must be in coll. Central Park Museum. The figure (Plate VI., 14) certainly does not look like a Ptilodont, rather like an Agrotid, but, especially an uncoloured figure, may be deceptive. A short classification of the J/e/a/ophide may be found in ‘ Ento- mologist’s Record, VIII., 107, but I find since that Phalera, Hiibn. Verz., 147, 1816,is preoccupied by Pha/eria, Latreille, 1804. Another name must be used for the genus of ducephad/a and the subfamily of which I made it the type. As to Datana,I1 rather missed an allusion to the fact that Grote and Robinson first drew attention that there were many closely allied species, and to the characters of the uneven margin, differ- ences in the lines and general tinting which serve to distinguish the moths. One paper in Vol. VI. of the Proceedings Ent. Soc., Phil., was an answer to the criticism passed by the late Mr. Walsh upon our previously described Datana perspicua. There is still a memorandum in my note-book of a reference in this genus which I do not seem to have published and which I do not find in either Packard or Dyar. A. RADCLIFFE GRoOTE, A. M. PRELIMINARY NOTES ON THE ORTHOPTERA OF Nova Scotia; by Harry Piers. ‘Transactions of the N.S. Institute of Science, Vol. IX., 1896. So little attention is paid to Entomology in the Maritime Provinces that we gladly welcome this contribution to the subject and are much pleased that Mr. Piers intends to devote some years to the study of the order Orthoptera. The paper before us gives some very interesting notes on the habits and range of fourteen common species of cockroaches, crickets, and locusts, and describes more at length the ravages committed by MWelanoplus atlanis on Sable Island, a hundred miles off the coast of Nova Scotia in the Atlantic Gcean.

We have much pleasure in presenting to our readers the excellent portrait of our colleague, the Rev. Thomas W. Fyles, who has been for many years an active member of the Entomological Society of Ontario. Though living at South Quebec, he has regularly attended the annual meetings at London, travelling many hundreds of miles in order to do so, and has invariably delighted those present with his excellent papers. He was a member of the Council from 1882 to 1888, when the change in the Act of Incorporation required the directors to be resident within certain districts of the Province of Ontario. Three times he has represented the Society as their delegate to the Royal Society of Canada at Ottawa, and he has been a member of the editing committee of the Canapian ENTO- MOLOGIST since 1889. While filling the arduous position of chaplain to the immigrants landing in Canada, under the auspices of the Society. for Promoting Christian Knowledge, he devotes any spare moments that he can get to the study of entomology. He has succeeded, with an energy and enthusiasm worthy of admiration, in forming an extensive collection of insects, and acquiring a knowledge of the science beyond what is ordi- narily met with. That he may long continue to carry on his excellent work, both in his official position and in his scientific pursuits, is the hearty wish of all his friends. A PARASITE OF HEMIPTEROUS EGGS. BY T. D. A. COCKERELL, MESILLA, N. M. The following description is offered of an insect to which I shall have occasion to allude in a forthcoming Bulletin, wherein such descrip- tive matter would be inappropriate. Hadronotus mesille,n.sp.— 3. Length slightly over 1 mm.; black; cox black, legs otherwise rufous. Antenne dark rufous, arising just above mouth, delicately pubescent ; pedicel oval, shining, punctured, conspicuously shorter than the long first flagellar joint ; second flagellar joint shorter than the first, but fully twice as long as broad ; third to fifth joints oval, shorter than the second, the third slightly longer than the Ww [op THE CANADIAN ENTOMOLOGIST. following, all longer than broad. Head short, broadly transverse, slightly broader than thorax ; lateral ocelli separated from the eyés by a space about equal to their own diameter ; a depression in front of middle ocel- lus. Frons and face minutely reticulated by grooves, reminding one of crocodile hide. ‘Thorax subglobular, somewhat broader than long, with very sparse short pubescence ; anterior part of mesothorax very indis- tinctly subreticulately sculptured, its anterior margin with a distinct row of pits. Hind portion distinctly but very delicately and minutely reticu- lated with raised lines. Scutellum smooth, with a few hairs ; hind margins of scutellum and postscutellum with a row of pits. Abdomen short and broad, carinated at sides, smooth, rather shiny. Wings hyaline, quite hairy, fringe short, nervures rufofulvous ; marginal vein short, not half length of stigmal. Habitat.—Las Cruces, New Mexico; bred from eggs of some Hemipteron, apparently Pentatomid. The eggs are barrel-shaped, pale gray with a white base and a white ring at top, the lid with a white central ringlet, and its suture white. Only one specimen was bred, and the tips of its antenne are broken off, but the species differs at once, by its reticu- late sculpture and other characters, from all those described by Mr. Ashmead in his Monog. Proctotrypide or in his work on the Hymenop- tera of St. Vincent. Another parasite of Pentatomid eggs occurs in the Mesilla Valley, namely, Z7/sso/cus euschisti, Ashm. (a Mesilla example det. Ashm.). With us, [ believe it is a parasite on the eggs of Brochymena obscura, H. S., which abounds in orchards. NOTES ON VANESSA INTERROGATIONIS, BY W. F. FISKE, MAST YARD, N. H. I remember about ten years ago to have taken several large speci- mens of a Grapta, probably G. cxterrogationis, but they were lost without being identified. I saw no more of the species until August, 1895, when I took a fine example of the form Fadriciz, It proved to be the forerunner of a “wave” of the species, and from that date until frost a number were seen, perhaps in all twenty or more, but all but two of them were of the form Faéricit. This spring I watched the hibernating butterflies closely, hoping to obtain a fertile female and rear a brood of larve, but although there were many G. comma and j-album, and a few progue and faunus, on the wing throughout April, I did not observe one énterrogationis amongst them. By the middle of May the other species of Grapta had {HE CANADIAN ENTOMOLOGIST, PA disappeared, or were represented by a few specimens worn almost beyond recognition. I had about given up meeting with ¢uterrogationis that spring, when on the 16th of May I captured a large but badly worn umbrosa fluttering over lilac blossoms. I was surprised that it should be of this form instead of the more common Faériciz, but what was my astonishment to see four or five more of the same form the same day. During the rest of May and first part of June the species was common, but not one Fadricii was seen. A large female was captured while Ovipositing on elm, and netted over a branch of that tree. She deposited a large number of eggs indiscriminately on leaves, branch, and net, in most cases singly, but in a few instances in ‘‘chains” of three or four. In order not to disturb the eggs, I let the net remain as it was until the larvee should hatch, and then, thinking that the larve would do better in the open air, left it until they had passed the second moult, when on removing it I found only eight remaining. These pupated without further accident, and on the 13th of July and the few days following five imagoes emerged —three Fudbricti and two umbrosa. This was after the larger part of the brood of 7-a/bum had emerged and several weeks after the first brood of comma, and as the former species is probably but single brooded here, I was not expecting a second brood of énterrogationis. It was with some surprise, therefore, that a large colony of young laryze were discovered in the latter part of August feeding on the heads of hops. Later several other colonies were found on hop and elm, and a number of larve were transferred to my breeding-boxes and carried successfully to pupation, but as many of the pup rotted, only about thirty imagoes, all /adr7cit, were obtained. The last specimen, delayed by a long continued “spell” of severe weather, did not emerge until November 6th, after being in the pupa state nearly six weeks and freezing at least once. I[t was smaller and darker than the average, but not otherwise remarkable. Now, the question which I wish answered is, Where did the large number of wmérosa come from that appeared here so suddenly in May ? They certainly did not breed here, because every specimen seen was badly worn, and they could not have flown in any such numbers either the same spring or the fall before, and besides, the fall before it was Fabricii that was in the majority. ‘he only explanation which I can offer is that they migrated thither from some other locality, probably in the South. Pyrameis atalanta appeared about the same time in very large numbers, but as the species has always been more or less common, 28 THE CANADIAN ENTOMOLOGIST. I did not think it so remarkable. The first brood of larvee of this species are usually so scattering that it is difficult to find them. This summer they were so numerous as to completely strip large clumps of nettle, so that numbers of larvee must have perished for want of food. Some large and healthy bunches of nettle were so weakened by the larve of this species and of Vanessa Milberti repeatedly stripping them of every green leaf that they have probably died. LARVAL STAGES OF AMPHION NESSUS (Cr.). | BY WILLIAM BEUTENMULLER, NEW YORK. Egg.—Pale green, almost globular; very similar to that of Averyx myron, but smaller. Young larvee collected at Greenwood Lake, New Jersey, June 25th. Length, 1 mm. Stage 7.—Pale apple-green, with numerous minute white dots and a narrow white subdorsal stripe along each side, beginning at the anterior part of the first segment and running to the hase of the caudal horn, which is black, and brown at the base. Length, 9g mm. Moulted June 28th. Stage 77.—Very much like the preceding stage, but the white dots and the subdorsal stripe are much heavier and more distinct. Caudal horn jet black, reddish-brown basally. Head with a narrow white stripe on each side. Length, 13 mm. Moulted July 1st. Stage [77.— Much like the last stage, but the stripes on the head are continuous with the ones on the subdorsum ; the third and fourth segments are now considerably swollen and thicker than the remaining segments. Caudal horn black, reddish-brown at the base. Spiracles black. Length, 17 mm. Moulted July 4th. ? Stage [V.—Same as the last stage. Length, 22 mm. Moulted July 7th. Stage V-—The general colour is now dirty orange-brown, speckled with small smoky-black dots. On the junction of the segment along the dorsum -is a smoky-black spot, and along the sides is a series of oblique smoky-black bands, the last one running to the base of the caudal horn, which is black. From the head to the end of the third segment are three black stripes, one on the dorsum and one on each side on the subdorsum. Head dirty purplish-brown, with a whitish stripe on each side. Under side darker than above. Length. 45 mm. Full-grown July 18. When fully fed the larva spins a rude cocoon between a few leaves on the ground.

Trine IX.—Gaverucini (Sub-tribe HALrIcIN1). . The “jumping beetles,” or ‘ flea beetles,” constitute the above sub- tribe, and are separated from the genuine Galerucini by the fact that the hind thighs:are greatly enlarged and thickened for leaping. Most of the species are quite small, though a few are of moderate size for this family, and a considerable number of them are prettily coloured. They are of great importance from an economic standpoint, a number of them being quite injurious. The identification of some of the members of this group is attended with considerable difficulty, yet most of the genera have a peculiar facies, which, once grasped, renders the proper location of addi- tional specimens tolerably certain. The sub-tribe has recently been worked up in detail, as far as the North American species are concerned, by Dr. Horn, from whose paper on the ‘“ Halticini of Boreal America” most of the tables and specific diagnoses have been condensed. His paper has rendered possible an intelligent survey of the group —something heretofore lacking in the American literature on the subject. The diagrams representing elytral markings are reproduced from the figures given in his article. A. Last joint of hind tarsi globosely inflated; elytra with confused punctuation, surface glabrous.

On page 577 of their great work on the Hemiptera, Amyot and Serville describe two species of Ledra. One, Z. awrita, the well-known species of Europe, was characterized from specimens collected near Paris. I have specimens of it now before me. Its size, the broad membranous prolongation of the head, the ear-shaped horns on the thorax, together with other details of structure, separate it widely from any other homopterous insect. The other species described, Z. perdita, though equally unique in form, was characterized under circumstances which, for such eminent scientists as Amyot and Serville, seem extra- ordinary. After a three-line description, they remark: “ L’exemplaire unique d’aprés lequel cette espece a été figurée, ayant été detruit, nous la décrivons d’aprés la figure.” ~Unfortunately, the figure, number five on plate II., is very poor. The species is credited to “ Amérique septentrionale.” Since that time the species has never again been recognized, although often noticed in hemipterological literature. Mr. Van Duzee, in his ‘‘ Catalogue of the Jassoidea,” lists it as an unquestionable Ledra, and gives its habitat as Pennsylvania, on the authority of Amyot and Serville. It is perfectly evident from the figure that the species is not a Ledra. It lacks utterly the characteristic head structure of Ledra aurita. It is equally evident that the figure is that of a Membracid belonging in the Centroline, near AZicrocentrus carye, Fh. Indeed, Dr. Goding tells me Fitch himself noticed this resemblance. During several years past I have been receiving quantities of - material in Homoptera from many localities in Pennsylvania and throughout the East.~ This material is the result of careful work by good collectors, and contains immense series of the native Membracids and Jassids. In the examination of this material I have been con- stantly on the watch for Ledra perdita. Lately it has occurred to me in several specimens from Pennsylvania, New Jersey, and Indiana, collected by Messrs. Dietz, Liebeck, and Weith. ‘There is nothing else among all the American material I have examined that is at ail like this species, with the single exception of Mucrocentrus cary@, and that lacks the long ear-shaped horns on the thorax. So peculiar in form is it that there is not a possibility of confusing it with anything else in our fauna, THE CANADIAN ENTOMOLOGIST. 539 ——— And not until another species from the same region shall have been dis- covered, having closer affinities with it than has AZicrocentrus carya@, will there be any reasonable grounds for doubting that this, which I so refer, was the form which Messrs. Amyot and Serville described under the name perdita. I forwarded specimens of the species to Dr. Goding, and was much surprised to learn that it was identical with his Centruchus Liebeckit, also from Pennsylvania, described on page 471 of the List of N. A. Mem- bracide. In a letter he cites the genus as “ Centruchoides,” which J suppose to be a manuscript name founded on this species. I, however, believe this species (which in future must be known as ferdita, A. & S.) to be congeneric with the carye of Fitch. I have specimens of carye with rudiments of thoracic horns. Outside of this character the species are very closely related. I have yet to see a true Zedra from either North or South America. SOME NEW SPECIES AND VARIETIES OF LEPIDOPTERA FROM THE WESTERN U. S. BY WM. BARNES, M.D., DECATUR, ILL. Argynuis Charlottit, n. sp. d.—Upper surface very much like Cyde/e; differs from Zez¢o in the lighter shade of the ground colour and the much darker and more exten- sive basal area. This area is sharply limited at the outer edge and extends to the median row of markings, which on the hind wings are quite obscured by it. The apical region is not so clear as in Zero, the row of round spots in the outer belt continuing of large size up to the costa, and the dark blotch lying just within the upper three spots is very prominent, as in Cyde/e. Under surface clearer, brighter, and markings less heavy than in Leto. The marginal brown shading very faint, and the submarginal row of crescents, which on the secondaries are very narrow but well silvered, have but a very fine edging of the same shade. The dark basal area stops sharply at the median row of silvered spots, as in Cydede, and is not present on their outer side, as in Le/o. ?.—Upper surface closely resembles Zefv, the ground colour and basal area being the same. The markings are, however, not so heavy and the submarginal row of lunules do not so completely enclose the row of spots of the ground colour. On the under surface the markings 40 THE CANADIAN ENTOMOLOGIST. © are not so heavy as in Zefo; the apical region is clearer, the three or four brown spots so conspicuous in Zefo being here wanting or but faintly indicated. The outer belt on the secondaries presents the same clean-cut character as in the male, owing to the absence of the brown shadings to its inner and outer sides. Types.—1 ¢ and 2 9s in my collection, from Glenwood Springs, Colo. This species stands intermediate between Zefo and Cydele. The locality has been thoroughly worked for several years and no typical Leto taken there. I have Zeto from Utah, California, Nevada, Oregon, Idaho, Montana, and British Columbia, and they are uniform in their points of difference from the form here described. Melitea Gillettii, n. sp. ¢ expands 1% inches; head and thorax black; abdomen black above, beneath yellowish- white; palpi and legs dark red; antenne fuscous ; club yellow; wings, ground colour black, markings dull red and white, veins black. Primaries above show a wide margin of the ground colour, in which are two rows of spots; the margin red, very faint, scarcely discernible except towards apex; the second row is white, small and not very prominent; the third row is red, the spots are large, quadrate and completely fill the intercellular spaces, thus giving the appearance of a broad red band cut by the black veins; the fourth row is rather irregular, white and joined opposite the cell by a demi-row from costa; two red and two white spots in celi; two white spots and one red in subcellular space ; basal area rather obscured with black. Secondaries above have the four outer rows as on primaries, the marginal red row even fainter, two red and one white spot in cell and a white subcellular spot. The under surface shows but little of the black ground colour, it being reduced to the veins and lines between the rows of spots, which are all rather quadrate in shape, filling the intercellular spaces, thus giving a well-marked, banded appearance. The marginal band is red and is followed by the white, red, and white bands as on upper surface. The cellular and subcellular spots on primaries same as above, only larger and more distinct. On basal area of secondaries there are four white spots, separated by an irregular shaped red area, the result of a fusion of the red spots. Described from seven ¢s taken in Yellowstone Park, Wyoming, July 18, Ce cata eta THE CANADIAN ENTOMOLOGIST. 4] —s Sa . =. This species is very closely allied to J7. 7éuna, Dalm,, of Lapland, but in that species the antennz are black and the red band not half so wide. That a species so distinct from any other thus far described from N. A. should be turned up at this late day is remarkable, and shows the possibilities of many other interesting discoveries when the Park region is thoroughly explored. Melitea nubigena, var. capella. In the Henry Edwards collection are specimens of a Melitea separated under the above name; but in so far as I know, no descrip- tion was ever published. The variations of xw4:gena are without number, yet they all come into one of three general classes. In Western Colo- rado and Utah the tendency is towards a gradual increase of the white at the expense of the red and black, producing forms allied to Wheeleri, Hy. Edw. Farther north in the Yellowstone region the tendency is to darker forms, the black replacing the red to such an extent that the spots are small and round, set in a_ black ground. Around Manitou and Denver forms occur which are of a solid brick red, the white being entirely gone and the black reduced to the veins and fine cross lines, the latter even being wanting in portions of the wings. On éhe primaries the spots at the costal end of the third row are the last to lose the white colour, and in most of the specimens there are traces of it remaining there. In some few males there is none whatever. The fourth row on the secondaries preserves the whitish colour the longest, but not so tenaciously as is the case on the primaries. In some specimens which have entirely lost the white, the black ground colour still remains well marked, while in others there is considerable fusion of the red spots, while considerable of the white is retained. It is to those dark red forms that Hy. Edwards applied the name cafe//a, and I take pleasure in retaining the name proposed by him. Described from eight pairs in my collection and others among my duplicates. Colias pelidne, var. Skinnert. Male, expanse 14 to 134 inches; upper surface of a greenish-yellow shade somewhat darker than Scudder/, lightly dusted with dark scales over costal two-thirds of primaries ; marginal bands not so broad and cut. less deeply by the yellow nervules than is the case in Scudder’. The inner margin of the border varies, being almost entire in some specimens, 42 THE CANADIAN ENTOMOLOGIST. dentate in others, and in a few erose. The discal spot on primaries black, much more distinct than in either Scudderi or pelidne. In some few specimens the spot is centered with a few yellowish scales, the spot on secondaries about the same as in Scudderi. Under side of primaries yellow, paler along the inner margin, thickly dusted with dark scales over costal two-thirds from base to just within the line where the inner margin of the black border of the upper surface shows through ; discal mark faint—scarcely discernible in many specimens. Secondaries thickly dusted with dark scales over the basal three-quarters, discal spot prominent, dark brown ring, centre silvered or white, more or less covered with roseate scales; costa and fringes, except at inner angle of primaries, roseate. Antennz roseate; club roseate below, brown above; collar, head, legs, and a spot at base of secondaries, roseate ; palpi roseate above, yellow beneath; thorax and abdomen dark above, covered with yellow hairs, yellow beneath. Female, expanse 15% to 17¢ inches ; greenish-yellow or white, about evenly divided. Border well marked, varying greatly in extent. In some specimens, on the primaries it is broad, and entirely encloses a row of spots of the ground colour; in others, while equally broad, it is uniformly dark; from these there are all gradations down to one in which the black is restricted to the apical region, and to pear-shaped spots at the ends of the veins. On the secondaries the border is usually well marked, and extends in some almost to anal angle ; in some examples, however, it is confined to the outer angle, as three or four blotches. The upper surface is less dusted with dark scales than in the male, the under surface about the same, the discal spots, fringes and other characters as in the male. Described from 15 males and 7 females — three of which are yellow, three white, and one intermediate — taken in Yellowstone National Park, and at Arangie, Idaho, in July. Mr. Bean, in CanaDIAN ENTOMOLOGIsT, Vol, XXII., p. 127, men-. tions specimens of a Colias intermediate between Scudderi and pelidne, and it is probable that this is the same, but as I have none of his material, and he gives no description of it, I am not certain. Thymelicus Edwardsit, n. sp. Upper surface bright golden-yellow, fringe dark brown within, lighter outwardly. Beneath primaries yellowish, except inner margin, which is shaded with black; hind wings yellow over the anal margin for one- third the width of the wing, rest grayish-yellow.

LONDON, MARCH, 1897. Nos 3: THE BLUEBERRY SPAN-WORM (DIASTICTIS INCEPTARIA, Wax.) AND THE BUMBLE FLOWER-BEETLE (EUPHORIA INDA, Linn.). BY M. V. SLINGERLAND, CORNELL UNIVERSITY, ITHACA, N. Y. On May 2oth, 1896, I received the following letter from a corre- spondent in Mount Vernon, N. H.: ‘‘I enclose you worms that are making sad havoc with the blueberry crop in this section. They seem to be great feeders, completely stripping the bushes of leaves and blossoms, but do not touch the green berries after they begin to form. The berry fields look as though a fire had passed over them, and the worms have nearly ruined the blueberry crop in this vicinity. “This blueberry ( Vaccinium penusylvanicum) needs no cultivation, only to burn over the old bushes every few years, when the new bushes will shoot up and bear the following year. There are hundreds of acres of land producing these berries in this and neighbouring towns, and so far as I can learn, about three-fifths of the crop has been déstroyed by the worms.” Accompanying the letter were four nearly full-grown span-worms and one pupa. The larve were new to me, and their ravages described above also made them interesting from an economic standpoint. One was therefore photographed, about three times natural size ; both dorsal and lateral views of it are shown on the plate. When full-grown the larvze measure about five-eighths of an inch in length and are peculiarly marked, as the figures show. The general colour of the body is light yellowish- purple. The dark portions are of a dead black colour. The sutures of the head are broadly margined with white, and a broad white band crosses the sides of the head. The mesal stripe on the dorsum is light yellow, as is also the narrow stripe extending along the subdorsal region through the large black areas, The broad stigmatal stripe is light orange-yellow, whitish below each large black area. Spiracles black. The large black subdorsal areas are in a broad light purplish stripe. The body is sparsely 50 . THE CANADIAN ENTOMOLOGIST. clothed with black hairs. ‘The true legs are black, with yellow bands at the extremities of the joints. Venter yellowish, tinged with purple. On May 22nd, one of the larve changed to a pupa on the soil in my cage. The worms would not eat the currant leaves placed in the cage. The pupa is of a very dark, shining brown colour, with the abdomen a little lighter and sparsely punctate. As the other pupa and the larvee had all died, the pupa just described was watched with much interest daily. At last, on the twelfth day (June 4), a dainty, modest little Quaker-gray moth emerged. It is shown, twice natural size, on the plate. About the only noticeable markings on the wings are one or two blackish spots on the costa of each front wing. The antenne are quite stongly pectinated. The moth was at once sent to Mr. Hulst, who determined it as Déastictis inceptarta, Walk. In an illustrated communication to the ‘Rural New-Yorker” for July 25, 1896, I proposed that the insect be popularly known as the “ Blueberry Span-worm,” in recognition of its destructive work on that plant. The moth was first described in 1862 (Cat. Brit. Mus., XXVI., 1667), from a Canadian specimen in the D’Urban collection. Dr. Packard again described it as avgi//acearia in 1874; this name was found to be synony- mous with Walker’s earlier name, évceptaria, by Mr. Moffat, as recorded by Mr. Hulst (Ent. News, VI., p. 11, 1895). Dr. Packard records the moth from Maine, Massachusetts, Pennsylvania, and Canada (Mon. of Geom., p. 258). He states that ‘‘it is very abundant in pine woods in Maine on a dry soil, rising and fluttering with rather a feeble flight, and soon settling again. In July, 1874, I captured thirty males before secur- ing a female ; the latter are apparently less ready to fly.” Heretofore nothing seems to have been known of the early stages of - this Geometrid. Whether there is more than one brood of the cater- pillars is not known. Doubtless the practice of burning over the blue- berry ‘fields every few years greatly checks the pest. The larve will prob- ably quickly succumb to a Paris green spray, and a little united effort among those interested would soon control this blueberry span-worm. THE BUMBLE FLOWER-BEETLE (Luphoria inda, Linn.). This yellowish-brown beetle, with its wing-covers sprinkled all over with small, irregular black spots (shown at a on the plate, twice natural size), is our most common flower-beetle in the North, ‘It is one of the first insects to appear in the spring. It flies near the surface of the ground, THE CANADIAN ENTOMOLOGIST. 51 with a loud, humming sound, like that of a bumble-bee, for which it is often mistaken. During the summer months it is not seen, but a new brood appears about the middle of September. The beetle is a general feeder, occurring upon flowers, eating the pollen; upon cornstalks and green corn in the milk, sucking the juices; and upon peaches, grapes, and apples. Occasionally the ravages are very serious.” (Comstock’s Man- ual for the Study of Insects, p. 565.) Although this beetle is so common, and has been known for more than a hundred years, nothing was recorded of its earlier stages (beyond the fact that it occurred in its various stages in the nests of ants) until December, 1894. Then Mr, Chittenden (Insect Life, VII., 272) recorded the rearing of the beetle from larve found in manure on Long Island. When found, July gth, the larve were encased in cocoons, and the last week in August these cocoons contained living adults. On June roth and July 8th, 1896, I received a large number of grubs from Mt. Kisco, N.Y. They were found in a manure pile that had not been disturbed since the preceding August, and from the soil beneath another pile made in October and moved in the following April. One of these grubs is represented, twice natural size, atc on the plate. When compared with a white grub (Zachnosterna, sp.), it was found to be con- siderably shorter and thicker-set ; its legs were not more than one-half as long, and its head was also much smaller than that of the white grub. The dull leaden hue of the body, due to the contents of the food-canal, indicated that its food consisted of dead vegetable matter rather than living roots, as in the case of the white grub. When they were placed on their feet or venter, they would crawl an inch or so and then roll over and crawl with considerable rapidity, with a wave-like motion, on their backs. I also found several similar grubs in a pile of rotting sod and manure which had not been disturbed for a long time. I have seen no evidence of their eating the roots of living plants. The grubs were placed in cages containing rotting sod and manure, in which they quickly buried themselves. Twenty days later, July 28th, the grubs had changed to pupz in earthen cocoons of the somewhat peculiar and definite shape shown, twice natural size, at 4 on the plate. Evidently the grub forms an earthen cell in the soil by rolling and twisting about, and then cements together the particles of earth composing the walls of the cell so as to form an earthen cocoon, which retains its form THE CANADIAN ENTOMOLOGIST. % or Lo when removed from the soil. Each cocoon has a curious roughened or more granular spot on one side (the upper side in the figure). The white pupa is shown, twice natural size, at @ on the plate. In pupating, the larval skin is shed off the anal end in the same manner as caterpillars do. In the case of the Spotted Pelidnota ( Pe/idnota punctata ), however, the larval skin splits down the whole length of the back, retains the larval shape, and forms a covering for the pupa, which remains inside. On August 13th, or sixteen days after pupz were found in the cages, several beetles emerged. They continued to appear daily until September 1oth ; more (33) emerged on August 22nd than on any other day. They proved to be Luphoria inda, Linn. This bumble flower-beetle evidently feeds only on decaying vegetable matter, as rotting sod or manure, and is thus destructive only in the ~ beetle state. The beetles seem to do most of their injury soon after they emerge in the early fall. One correspondent wrote me that he collected forty-five of the beetles in one day on asingle ripe peach. Doubtless the beetles hibernate, but whether egg-laying takes place in the fall or spring is not known. ‘The fact that manure piled in August and October con- tained many nearly full-grown grubs the next June indicates that the eggs are laid and hatched in the fall, otherwise the grubs must develop very rapidly after hatching from eggs laid in the spring. ‘There seems to be one brood of the insect in the course of a year. Hand-picking of the beetles is apparently the most practicable method of combating it when it is found working on ripe fruits or on green corn. Since the above was written, some further notes on this insect (read by Dr, Lintner at the Buffalo meeting of A. E, C. last August) have been published. Larve were sent to Dr. Lintner in chip manure in the latter part of June. On August 8th two beetles had emerged in his cage, and an examination of the earthen cells revealed other beetles and several pupx. An instance is given which seems to indicate that there is a possibility that the grubs may have attacked growing corn, but the evidence is not conclusive.

The interesting new species of water-bug described below was received. some time ago from Abbé P. A. Bégin, of Sherbrooke, Canada. It was captured swimming on a fresh-water stream some little distance above Sherbrooke, and is of more than ordinary interest, from the fact that it belongs to the genus /a/odatopsis, Bianchi*, a genus not yet recognized in the North American fauna, and only recently characterized, being based upon the South American Hadodates platensis, Berg., also a fresh-water species. Halobatopsis Béginii, n. sp. ?.—Length, 2.3 to 2.5 mm. Oval, velvety black ; a yellow dot or spot on middle of pronotum anteriorly, a larger,somewhat triangular,yellow spot, but more or less variable in shape and size, on the upper basal hind angle of the mesopleura close to the base of the metapleura, while beneath, the mesosternum anteriorly and posteriorly and along the median furrow or suture is more or less broadly margined with yellow. Antenne scarcely two-thirds the length of body; the first joint subclavate, slightly curved, shorter than the three following joints united, but distinctly longer than joints 2 and 3 combined; joints 2 and 4 subequal, longer than the third, the latter being about three-fourths the length of the second ; the fourth or last joint is fusiform. The legs in all my specimens are broken, but are similar to those found in Zrepodates, Uhler (= Steph- ania, White), the middle legs being much the longest pair. The anterior legs are very short, shorter than the body ; the femora, with their tro- chanters, being about as long as the tibize and tarsi combined ; the tarsi, consisting of only a single joint, being a little longer than half the length of tibiae ; middle legs very long, their femora alone being as long or even longer than the body, the tibize being fully one and a half times as long as the femora, the tarsi about half the length of tibie. The hind legs in all my specimens are broken, but the femora, which alone remain, are much slenderer and considerably longer than those of the middle pair. Hab.—Sherbrooke, P. Q., Canada. Dedicated to Abbé P. A. Bégin, the discoverer of the species and a most valued correspondent. *Ann. Musce Zool. ’Acad, Imp. des Sci. de St. Petersburg, 1896, p. 70. Jt ~I THE CANADIAN ENTOMOLOGIST. MAMESTRA CIRCUMCINCTA, Smiru. BY JOHN B. SMITH, SC. D., NEW BRUNSWICK, N. J. The above species was described by me in the Proceedings of the U. S. National Museum, Vol. XIV., page 253, in my revision of the genus Mamestra. Recently Mr. Grote has questioned the distinctness of this species from o/ivacea. I could hardly credit this as being serious, and barely referred to the matter in the September, 1896, number of the CANADIAN ENTOMOLOGIST, page 240. In the December number, page 301, Mr. Grote returns to this subject, and again suggests that circumcincta may be either o/ivacea or comis. He refers to the fact that the descrip- tion resembles that of both the species cited by him, and brings in Mr, Beutenmiller to testify to the fact that my species closely resembles olivacea. Mr. Beutenmuller is not a specialist in the Noctuide, and not entitled to an opinion that would carry decisive weight. Furthermore, it was not fair to Mr. Beutenmuller to ask him to make the comparison without first referring him to my description. Mr. Grote speaks as if the statement that c7rcumcincta, or its description rather — for he has never seen the species — resembles o//vacea was an important one and a dis- covery of hisown. He does not refer to the fact that in my description I say: ‘the male resembling o/:vacea so strongly that I compared it closely at first, expecting a variety of this protean form.” It seems to me it would be impossible to state more definitely the fact that I recognized the very close resemblance, superficially, between the species newly de- scribed by me and the very variable one long ago characterized. Mr. Grote also omits entirely the fact that the last sentence in the description and my comment on it reads: ‘“ The sexual characters, however, refer the species to the rvenigera group.” On plate X., accompanying my paper, I delineate the sexual structures of cércumcincta at figure 52, and of o/ivacea at figure 53. The two are so utterly different that it is simply impossible that one type should be a modification of the other. My species is, therefore, based upon a structural character primarily, and after that upon colour and markings. Now, if Mr. Grote will claim that these structural characters are not of specific value, then the question of whether my species may be o/‘vacea is open for discussion. Until he takes this stand, these two species cannot be compared for a moment whatever their superficial similarity may be. I have asserted time and again that differences in sexual structure invariably indicate differences jn species. Many other Entomologists have taken the same stand. Mr, THE CANADIAN ENTOMOLOGIST. or oe) Grote has not, so far as I know, taken any stand in the matter, except so far as to deny the value of these characters for generic separation. If he is willing to assert that these structures have no specific value, then the question is an open one ; but I submit that to bring the matter before the readers of the CANADIAN ENTOMOLOGIST, as if there was a mere matter of colour and marking to be considered, is neither scientific nor honest. Before suggesting the identity of the two species he should have referred to the fact that I recognized their superficial resemblance, and separated them upon a distinct structural character. One other point in Mr. Grote’s paper is worth noting. In the matter of Agrotis crassa, Mr. Grote excuses his failure to recognize the true character of the frontal structure by stating that neither he nor the Museum with which he is connected possesses a microscope. He does not distinctly say so, but it would seem as if neither did they possess an ordinary hand lens of frem 1% to 34 inch focal length, which is all that is necessary to recognize external structures of Noctuid moths serving for the division of genera. If not even the simplest and most necessary . appliances for study are at hand, is any man justified in making assertions on points concerning which he cannot have any possible certainty? But even without the optical assistance to which I have referred, surely either Mr. Grote or the Institution at Hildesheim has in its possession a little camel’s-hair brush, and with this, or even the frayed end of an ordinary wooden toothpick, the scales from the front can be sufficiently removed to enable one to recognize the frontal structure with the unassisted eye. One who makes assertions as to structure, should at least take every means within his power to make certain that they are accurate. Mr. Grote evidently has not done this, and in every assertion that he has made, concerning the identity of genera in this /¢/¢ia matter, I have — proved him wrong. ‘To escape from the necessity of considering his genus Carneades a synonym of Agronoma, he seems now to be willing to recognize the distinctness of the division that I have called Porosagrotis, basing it, however, upon the fact that the antenne in the typical species are pectinated. This he considers a good generic character, differing in that point from all the authors who have written on this genus. Unfortu- nately, the genus Carvneades contains species with antenne pectinated and antenne serrated, and so also does the genus that I have called Porosagrotis. There is no line of distinct demarcation between these two types of antennal structure, so that I could not utilize them even for THE CANADIAN ENTOMOLOGIST. 59 divisions within the genus. ‘The ordinary type of antenna in Carneades is what Mr. Grote has called brush-like, and consists of joints with more or less marked lateral projections, bearing on all sides stiff, bristly hair. It is the form that is called “ bristle-tufted” by other authors. The lateral projections vary in size in the species, and when they become evident to the naked eye the antenna is called pectinated. The pectt- nations may be long or short, and the distinction between a shortly- pectinated antenna and one that is merely “brush-like” is entirely a matter for the individual judgment of the author who uses the term, as the two forms grade into one another imperceptibly. Mr. Grote cannot escape either admitting that the sexual character that I have made use of to separate Porosagrotis is a good one for the generic purposes or ad- mitting that Agronoma must supercede Carneades. It does not make any difference to me which he chooses, because it does not distress me, as Mr. Grote says it does him, to have any name proposed by me relegated into the synonym, whenever there is scientific cause for it set forth by one whose methods of work and accuracy of research entitle him to the confi- dence of those for whom he writes. MONODONTOMERUS IN APPALACHIA. BY W. H. PATTON, HARTFORD, CONN. MOoONODONTOMERUS STIGMA (Fabr.). M. virideneus, Prov., Canada. Common in New England. In the District of Columbia I have reared it from the cell of A/e/itoma euglossoides, var. taurea, Say. The genus O/igosthenus cannot remain separated, the fine dentitions of hind femora being more or less indistinct, A frequent variety has no cloud about stigma. The abdomen varies in the amount of purple. A mave taken by me at Hartford, Conn., Aug., 1895, differs de- cidedly from the male of JZ. montivagus, Ashm., described by Mr. Cocke- rell in the Can. Ent., XXVIII, 127, May, 1896. My male measures 3 mm. in length. It has no cloud about stigma ; the abdomen is purple, except apex and most of the first segment. ‘The scape is slender, as in the female ; the flagellum is as in the female. Hind cox and femora much more swollen than in the female, tooth longer, no denticulations. The abdomen is short, broad ; dorsum flat, shining. The descriptions of the females do not differ specifically. 60 THE CANADIAN ENTOMOLOGIST. THE Goi pame e OF CANADA. BY H. F. WICKHAM, IOWA CITY, IOWA. XXII.

Prothorax more coarsely sculp- tured above than the elytra, each side with three sharp teeth. The head bears a deep, sharp im- pression between the eyes.

The next sub-family, the Cerambycine, is of great extent, and in consequence more difficulty is encountered in arranging the genera. In the use of the table considerable care must be exercised by those who are unfamiliar with the structure of the Longhorns. This is especially true of the first character involved, z.e., the enveloping of the base of the antennz by the eyes. In order to obtain a proper appreciation of this structure, the antennee should be extended forward from the head: in this position it will be seen that in those genera where the “base of the antennee is partially enveloped by the eyes ” a line passing from the anterior or inner border of the upper lobe of the eye to a corresponding point on the lower lobe will pass through the antennal socket, whereas in the other genera this line would run behind the socket. Of course none of the genera in which the eyes are entire (7. ¢., not emarginate) will belong to the former category, though those with emarginate eyes may belong to either. Com- parisons of a few specimens ought to make this clear.* The remaining characters may be easily verified by careful examination of a few species the positions of which are already known to the student, and with these as a point of departure he should meet with no greater difficulty than is always to be expected in dealing with a group of large size, wherein col- our and sculpture are inconstant and secondary sexual characters well marked. The following table is submitted for generic discrimination ; a short account of the method of using may be useful to some. Suppose on taking up our insect, which we have previously ascertained to belong to this sub-family, we examine the position of the base of the antennze with regard to the eyes, since this is the first point of departure : ascer- taining the antennal bases to be partly enveloped, we find ourselves referred to the number rz at the end of the line. We now run down_ along the numbers at the degézmzng of the lines until we reach 12, which shows us where to recommence our analysis, with a scrutiny of the second antennal joint. Suppose we find this joint large, we are referred to the number 36, under which (on searching out its position at the beginning of a line) we are again confronted with a query, this time as to the relative proportion of the second joint to the fourth ; if these two joints are about *Cases will, however, arise in which this point is in doubt. In such an event the choice will rest between the Callidioides and the Cerambycoides. The former have the second antennal joint larger (as a rule) than the latter, but I can find no hard and fast distinction which will serve the beginner as a sure test. A certain number of properly named specimens serving as a guide to tribal and generic facies is almost indispensable here, It should be stated that the table is based on the characters developed in the ‘* Classification,”? but is intended to apply only to the Canadian fauna, a THE CANADIAN ENTOMOLOGIST. 85 equal, our insect belongs to AZicroclytus.

The interesting note by Prof. Baker on Ledra perdita ( Centruchus perdita, A. & S.) deserves notice on account of the mystery which it clears up, and it may also be worth while to add some testimony in the way of corroborative evidence. A few weeks ago (Dec., ’96) I had occasion to review the matter in an attempt to locate the serdzta, and, in a critical examination of Amyot and Serville’s figure and description, was struck by the resemblance to our common MWicrocentrus caryé. On careful comparison, however, with this species and with the Centruchus Liebeckii of Goding, I concluded the figure and description must apply to the latter. It seemed so strange that a connection so obvious, when once seen, should have so long escaped the attention of Homopterists that I made a further search in the available literature, with the result of finding in a note by Dr. Goding, on “ Fitch’s Types of N. A. Membracidz” (Canap. Ent., Vol. XXV.,p. 172), the state- ment that “ No. 2152, labelled Ledra perdita and capra, Mels., is Cen- truchus Liebeckii, Godg.” There is no comment to indicate that Dr. Fitch corrected the family reference from Ledride to Membracidz, but considering his familiarity with the Homoptera in general, and the Mem- bracide in particular, it is probable that he appreciated the full signifi- cance of his specific determination, and it is quite likely that his un- published notes would show comments on this reference. In any case, we have the testimony of Dr. Fitch in identifying his specimen as Ledra perdita and its recognition by Dr. Goding as Centru- chus to confirm Prof. Baker’s conclusion. OCCURRENCE OF SCHISTOCERCA AMERICANA (Drury) AT TORONTO. Mr. C. T. Hills recently brought me a specimen of the large, hand- some locust, Schistocerca Americana, Drury, which was taken about the t2th of October, 1896 (the exact date was not recorded), by Mr. H. Parish, while collecting at High Park. Mr, Parish found the insect rest- ing on the trunk of atree. The specimen is a female, in perfect’ con- dition, measuring 4.75 inches in expanse of wing, and is in every respect similar to examples of this species which I have from Tennessee. This is only the second time it has been taken in Canada; Mr. J. A. Moffat having recorded it from London (Can. Env., XXVIL, p. 52.). KE. M. WaLKErR, Toronto, \ 90 THE CANADIAN ENTOMOLOGIST. NEW COCCID4 FOUND ASSOCIATED. WITH ANTS. BY GEORGE B. KING AND T. D. A. COCKERELL. [The species described below were all collected by Mr. King. The notes on the microscopical characters were prepared by Mr. King, but have been extended and rewritten from Mr. King’s mounts by Mr. Cockerell, who is also responsible for the comparisons with allied species. The notes on the living insects, habitat, etc., are all by Mr. King. ] Lecanopsis lineolata, Nn. sp. 2 (cleared and mounted).—Oval, length somewhat over 2mm., dermis. practically colourless, legs and mouth-parts tinged with sepia, anal plates a warm yellowish-brown, quite a different colour from the legs. The mouth-parts inclined rather to a madder-brown. Legs and antenne small, hind legs not nearly reaching the anal plates, tip of femur of middle legs reaching extreme base of hind legs. Posterior cleft wide. Antennz fairly stout, gradually decreasing in size distad, 8-jointed: 3 longest, not quite twice as long as broad; 2 and 4 next, and about equal; 5 and 1 of about equal length, but r much broader than long, 5 longer than broad ; then the last three subequal, but 8 the longer. Formula 3 (24) (15) 8 (76): 8 with several small hairs. Anterior tibia and tarsus as long as antennal joints 2 to 6, the tarsus about half as long as tibia ; femur very stout, not as long as tibia on its inner side, but a little longer on its outer; trochanter and coxa both very large. The legs are altogether noticeable for their stoutness, but the basal parts are especially enlarged. Claw large, moderately curved, digitules of claw stout, extending beyond its tip; tarsal digitules filiform, all but two broken off in the specimen. The claw- digitules are enlarged at ends to an obliquely truncate club, but the tarsal digitules with only an excessively minute club. There is the usual long bristle at the tip of the trochanter, and a short erect hair a little way up the femur on the inner side. Anal plates rather broad, the caudolaterai side a little longer than the cephalolateral ; a large bristle near the tip and another at the extreme base; these bristles are very large, and may possibly be dermal, beneath the plates ; especially as there is a corre- sponding pair on the skin laterad of the plates, that opposite the hindmost bristle being considerably shorter than it. Hairs of anal ring broken, but apparently they were stout and not numerous. Skin without any distinct markings ; marginal spines fairly large, pointed, simple, easily deciduous, a very little further apart than the length of one. Stigmatal spines in threes, one long, two much shorter but not very short. THE CANADIAN ENTOMOLOGIST. 91 Hab.—With Cremastogaster lineolata, two specimens in a nest at Lawrence, Mass., July 15th, 1894. This is not a strictly typical Zecanopsis, but belongs apparently in the subgenus or genus Spermococcus of Giard. By its 8-jointed antenne it resembles Z. formicarum, Newstead, but it differs at once from that by the smaller (though still large) first antennal joint, the longer second joint, the much longer third joint, the femur decidedly stouter, the tibia not beset with numerous bristles, and the claw-digitules stout. Lecanopsis is simply a segregate from Zecanium, modified for underground existence. Maskell’s Zecanopsis filicum hardly belongs here ; in some respects, but not in others, it seems to approach A/yxolecanium ; it also recalls in some of its characters such forms as ZLecanium Urichi. Phenacoccus american@, n. sp. ?.—When alive fusco-testaceous, smooth, soft, sticky, and free from any wax or down; when put into alcohol its colour changes to a rufous- violaceous, and it becomes quite wrinkled, its general form is rounded, with a slice of nearly one-fourth cut off, making its under surface flat. Length (in alcohol) 314 mm., width 3 mm. ? (cleared and mounted).—Oval, brown of a rather warm sepia tint, antennz and legs very pale yellowish. The legs are slender, and although the insect is much larger, its legs are not so large as those of some of the ant’s-nest species of ARzpersia; but at the same time they are well-formed and ordinary, not shortened or swollen as in the Lecanopsis. Trochanter with one long and at least two short bristles. Femur little longer than tibia, its inner margin straight, with four or five erect bristles; its outer margin very gently arched or bent, with a conspicuous erect bristle at the bend. Tibia slender, with eleven conspicuous bristles, tending to form three whorls. Tarsus rather over two-thirds length of tibia, with similar but finer bristles, no nobbed tarsal digitules. Claw large, little curved, with a minute denticle on inner side near the tip ; digitules of claw extending beyond its tip, slender, with hardly noticeable knobs. Antenne slender, club not conspicuously swollen, formula 9 (123) (45678), or it might be written as well 9132 (87) (456), but the additional differences indicated by the latter formula are almost too slight to be accurately measured by the eye: 9g is very nearly as long as 7 +8; 1 is cylindrical, its base not noticeably wider than the apex. The joints have sparse whorls of hairs, 9 having two such whorls. Eyes prominent. Mouth-parts small, mentum (so-called) very obscurely or not 99 THE CANADIAN ENTOMOLOGIST. = — —E dimerous, broad and short, its apical half with three whorls of erect bristles. Skin with sparse small round gland-spots. Hab.—Andover, Mass., Oct. 27th, 1896, under a stone in the nest of Lasius americanus, Emery. A small colony of five individuals captured, and only one herd as yet found; they were not feeding on any roots entering the nest of the ants, but were altogether on the surface of the nest, and some of the ants were attending them. It is to be presumed that they would eventually produce cottony matter. Both by colour and habits this differs at once from P. aceris, Sign., which has been recorded from Massachusetts, and there is no species with which it is likely to be confounded. Ripersia Blanchardit, n. sp. @.—Dark reddish-purple, segments prominent, much broader in front, pointed behind, subglobular or subelliptical, convex, antennz short and thick. Length, 2mm.; breadth, 1% mm. 2 (cleared and mounted).—Skin quite thickly beset with round gland-spots, and also minutely hairy, the minute but abundant pubescence being a striking characteristic of the species. So abundant are the hairs in the vicinity of the anal ring that it is impossible to be sure how many really belong to the latter, though there seem to be six, the usual number. The legs, antennze and mouth-parts are tinged with ochreous, and are large for the size of the insect; particularly the mouth-parts, which have at least twice the diameter, and many times the bulk, of those of the larger species Phenacoccus americane. ‘The mouth-parts are also much broader in proportion to their length than in P. ameritcane, and the rostral fila- ments are quite stout. The antennee are stout, 6-jointed, just about as long as in P. americana, but very much stouter and quite different in appearance. The formula is (36) 21 (45), but if anything, 3 is a little longer than 6; 3 about twice as long as broad; 4 and 5 broader at apex than at base, so that the sutures between 3 and 4, 4 and 5, and 5 and 6, are very deep, the last two approaching a right angle. The whorls of hairs are very sparse. ‘The legs are also peculiar; fully a third longer than in P. americane, and very stout, with large coxe and trochanters, they are tolerably thickly beset with small hairs. The tarsus is somewhat over two-thirds the length of the tibia, and tapers quite rapidly froma broad oblique base, it shows a slight tendency to be jointed a little before the a kt a eT el ee i Oe ee ee eee ee eS eee He ee ee ee ee ae 9 THE CANADIAN ENTOMOLOGIST. 9) end.

Hab.—Haverhill, Mass., Oct. 4th, 1896, in a nest of Lastus claviger, Rog., under a stone with a small herd of another species ; only one found, not feeding. Named after Mr. Blanchard, who has interested himself in the Coleoptera associated with ants in the same region. Of the Massachusetts species, this most resembles &. Zaszz, particu- larly in the antenne, but it differs widely in its colour, hairiness and stout legs. Still less does it seem to resemble any of the foreign species. Reviewing the above three species, it seems that the Lecanopsis is most modified for an underground life, the Rzpersza somewhat, but the Phenacoccus hardly or notat afl. Itis probable that the last will be found in summer on some plant above ground. ARGYNNIS IDALIA IN NEW BRUNSWICK. On February 1st I happened to spend a few hours in St. John, N. B., and through the kindness of Mr. Herbert E. Goold, of Sussex, N. B., and Mr. A. Morissey, cf St. John, I was enabled to visit the very interesting museum of the Natural History Society of New Brunswick. In looking over the cases of insects I noticed two fine specimens of Argynnis idalia, which Mr. Goold told me were taken by himself or his father at St. John. I could not remember at the time any record of A. zda/ia having been taken in New Brunswick, so asked Mr. Goold to enquire from his father if he remembered anything of the capture. He has since written to me: “In re Argynuis idalia—On my return home from St. John I asked my father about the specimens. He remembered the circumstances of their being caught distinctly, as he was perfectly familiar with the insect, having been one of the most active members of the entomological branch of the Natural History Society of Portland, Maine. In 1880 quite a number of specimens of A. zda/ia appeared in the vicinity of St. John, and the specimens you saw were taken at that time.” It is to be deeply regretted that at the present time very few members of the strong local Natural History Society at St. John are studying entomology. ‘The locality is one of extreme interest scientifically, and very much requires working up.

ON REARING DRAGONFLIES. BY JAMES G. NEEDHAM, ITHACA, N. Y. Field work in Entomology is full of delightful opportunities, and none, just at present, is more inviting, none more certain to repay well even a little effort, none more sure to yield discoveries of scientific value, than work upon the life-histories of Dragonflies. Of the species occurring throughout the central tier of States, a majority perhaps has now been bred; but of the Canadian, far western and southern species the known nymphs are few and far between. The nymphs (fig. 15), which are ail aquatic, have an interesting distribution in depth. Those of Agrionidae and of most Aeschninae cling to floating or submerged vegetation. These at least every aquatic collector has seen. Those of Libe/- lulidae sprawl upon the bottom amid fallen trash. Those of Gomphinae burrow shallowly along be- neath the film of sediment that lies on the bottom, with the end of the abdomen turned up for respira- tion. It is very easy to collect them, especially in spring. A garden rake with which to draw ashore the stuff to which they cling and a pail of water in which to carry them home is all the apparatus Fie. 1g)-2Arscuvin neuen. Gesitable at (that, season. Later, when a new growth of weeds is rooted fast to the bottom, the rake will have to be exchanged for a water-net. Withdrawn from the water, the nymphs render themselves evident by their active efforts to get back, and need only to be picked up. The number of species one will find will generally depend on the variety of aquatic situations from which he collects. The places apt to yield the best collecting are small perma- nent pools, shallow inlets in the shores of lakes, and the places where the trash falls in the eddies of streams. They are quite as easily reared. I have found common wooden kits and pails half filled with water, with screen or netting covers, entirely satisfactory. A number of nymphs, if near one size, may safely be kept together (excepting only a few notoriously cannibalistic Aeschninas: «. g., Anax junius), andif not grown may be fed upon such small insects as a net will gather in any pond. A good square meal once a week will keep THE CANADIAN ENTOMOLOGIST. 95 them thriving. The water should be reasonably clean. Three things should be carefully observed. (1) There must be a surface up which they can climb to transform: if the sides of the kit are too smooth put in some sticks; (2) there must be room enough between the netting cover and the water for complete expansion of their wings ; (3) they must remain out of doors where the sunshine will reach them. This last point especially is essential to success. But there is still an easier way to do it, and one which, when a species is very common, will prove entirely satisfactory. The several nymphal stages (excepting the youngest, not likely to be collected) are very much alike. I am in the habit of preserv- ing the younger nymphs and putting into my kits only those well grown, as shown by the length of the wing-cases, which should reach the middle of the abdomen. But if, when a species is becoming common, one will go to the edge of the water it frequents, at the time of its emergence, one may find nymphs crawling from the water, others transforming, imagoes drying their wings, and others ready to fly, and may thus obtain in a few minutes the material necessary for determining nymph and imago. The time of emergence may be determined by noticing at what time pale young imagoes are seen taking their first flight, and then going out a little earlier. The unfortunate thing about it is that many of the larger species transform very early in the morning, and to take such advantage of them one must be on the ground between daybreak and sunrise. Several imagoes should be kept alive until they have assumed their mature colours. It is most important that each imago and its cast skin should be kept together. Eggs, also, are easily obtained. Every collector has seen the female of the species figured on the front of this magazine, or of related species, dipping the tip of her abdomen into the surface of the water, depositing eggs. If the ovipositing female be captured, held by the fore wings, leaving the hind wings free, and “ dipped” by hand to the surface of clean water in a vial or a tumbler, an abundance of eggs will usually be liberated. Eggs of those species which possess an ovipositor and which place them within the tissues of plants may be obtained by collecting the stems in which they have been inserted. Eggs and nymphs should be dropped in boiling water for a minute and then preserved in alcohol. Imagoes, if mounted, should have a wire or bristle inserted into the body its entire length to prevent otherwise 96 THE CANADIAN ENTOMOLOGIST. certain breakage, or if placed unmounted in envelopes, these should be of soft paper, loosely packed, so that the eyes will not be crushed. In my own field work upon Dragonflies I try to cover for each species the points of the following outline : I, Imago. (1) Name ; locality ; date ; occurrence ; etc. (2) Haunts: places frequented; places avoided; the reasons, if discoverable. (3) Flight: its hours; its duration ; its directness ; average altitude ; places of rest: altitudes. (4) Food: its kind ; how obtained ; where eaten. (5) Enemies: what are they, and how do they destroy Dragonflies ? (6) Oviposition: does the 2 oviposit alone or attended by the 7. (7) The eggs: where placed ; number in a place ; incubation period. II. The Nymph. Points 1, 2, 4 and 5 of above, and Imagination: hours; places ; distance from water ; etc. I shall have to admit at once that it is very difficult to determine all these points for a single species, but the effort will lead on into delightful intimacy with these beautiful insects. At the kind invitation of the editors, I venture to say to the readers of this magazine that I am now engaged upon a semi-popular monograph of N. American Dragonflies, which, in so far as it includes accounts of habits and life-histories of the species, must of necessity be a co-operative work. And I have written this to invite co-operation. The foregoing simple methods are the very best. I will furnish (if desired) half a dozen named nymphs of typical genera to any one who will undertake to collect and rear others. I shall be very willing to determine nymphs or imagoes for any one, and to point out for description such as are new. But I especially desire that accurate field observations and notes be made on many of our species of which we now know only the names, and to such observers I will give all possible aid.

BY HARRISON G. DYAR, PH. D., NEWYORK. The difficulty of defining species in this genus is increased by the constancy of the local forms or races. I have elsewhere referred (ut. News, VII., 218) to the race of /w/vicosta which Mr. O. D. Foulks has discovered at Stockton, Md. Mr. Foulks was so kind as to send me over 100 hibernated larve, from which I bred a long series of moths. The type form is large, the size of reversa and co/ona, both wings imma- culate yellowish-white, head, collar and the tips of the abdominal rings ochre: yellow. In var. A the fore wings are nearly pure white, the hind wings much yellower, suggesting conscita, though never so dark as that form. In var. & the ground of fore wings is white, marked faintly with ochreous bands in which the full pattern of co/ona can be traced; the costa is narrowly brown-black ; the hind wings are pale ochreous. This looks like a washed-out co/ona, related to it in the same way as var. A. is to conscita. Var. C is only slightly yellowish on both wings, the hind wings scarcely at all darker ; fore wings marked with various streaks and spots of brown-black, especially along the costa and margins, all more or less distinctly connected by ochreous shades, in which the full pattern of reversa can be read. This is a washed-out reversa, stained with the creamy yellow so characteristic of the Maryland race. All these forms insensibly intergrade. I believe that this is prac- tically the extent of variation in this Maryland race. There are no specimens that are true col/ona, conscita or reversa, but these forms are all strongly suggested. The view naturally presents itself that these names apply to local races rather than to distinct species. In his work on Callimorpha (Proc. U. S. Nat. Mus., 1887, p. 338) Prof. J. B. Smith describes the genitalia of colona, Lecontei, contigua, reversa and vestadis. The differences shown are at best slight, and Prof. Smith assumes the 98 THE CANADIAN ENTOMOLOGIST. forms which he figures to be constant. In fact, they are not so. I have drawn the right side pieces of four males of the Maryland race of fulvicosta. They are shown in figures 1 to 4, viewed from within x 50, the dorsal angles down. These are not specimens selected for their variation, but are all that were mounted. The only selection applied was in taking the poorest specimens for dissection. Fig. 1 shows the upper angle produced and rounded, the lower angle much more pro- duced ; fig. 2 shows the lower angle not produced, but simply rounded ; fig. 3 both angles produced, the upper the most so; fig. 4 both angles produced, but the lobes of quite different shapes. There is as much variation in these specimens of /w/vicosta as in all of Prof. Smith’s “species,” and I am of the opinion that the genitalia are valueless as a means of specific distinction in Haploa. However, I add drawings of most of the other forms and also reproduce Prof. Smith’s figures. It is possible that the larve, when fully known, will be of more help, yet this is doubtful, as they seem to possess all the same habits and hence are not markedly different in their colours. Very full descriptions are needed, especially of the mature larva, to test these points. The following observations were made on the larvae sent by Mr. Foulks and on the young ones bred out of the eggs from the moths. Normal number of stages six; hibernation in the fourth or fifth. The young larve that were selected for observation passed two inter- polated stages between the normal II. and III. and died before reaching stage IV. Egg.—Of the shape of two-thirds of a sphere, scarcely conoidal, the base flat; smooth, shining, rather dark yellow; diameter .6 mm. Reticulations obscure, visible in a strong reflected light, very narrow, linear, irregularly hexagonal, the cell areas flat, uniform, no shadows. Stage 7—Head high, bilobed, the lobes blackish brown, clypeus pale, mouth brown ; width .3 mm. Body pale yellowish, tubercles dusky pearly ; hair short, stiff, white. Sete single, normal, no subprimaries ; feet pale. The larva grow considerably, becoming long and slender, the tubercles surrounded narrowly by brown. Stage ZI.— Head black, shining, clypeus whitish, jaws brown ; width .4g mm. Body whitish, warts rather small and with the shields deep shining black ; hairs not numerous, but forming true warts, short, bristly, black. A wide space between tubercles i. suggests a dorsal band Warts each narrowly edged with brown, most distinctly subdorsally, no connected marks, Subventral hairs pale. HE CANADIAN ENTOMOLOGIST. 99 Stage ///. (interpolated)—Head shining black, clypeus and mouth brown ; width .55 mm. Warts large, black, hairs short, bristly, black and white. Body elongated, broadly whitish between warts u., fading to smoky black in the region of wart iii; below this another pale band, marked with yellow, transversely annulated streaks behind wart iv., two on each segment ; subventral region shaded with brown. Leg _ plates black. Later the appearance is more as in the next stage, though the bands are not really defined. Stage ZV. (interpolated) — Head black; width .65 mm. Body black, a broad diffuse dorsal gray line, joining a narrower subdorsal one. Region of warts ili. and iv. yellow spotted, joining a substigmatal gray band and subventral gray marks. Warts black ; hair short. Stage V. (normal III.)—Black ; head .75 mm. Pale whitish dorsal, subdorsal and substigmatal lines, the subdorsal faintest; bright yeliow superstigmatal line, not perceptibly joined to the substigmatal one. Warts black. Normal Stage V. (from Mr. Foulks; after hibernation) — Head shin- ing black ; width 1.7 mm. Body black ; dorsal line broad, subdorsal faint, stigmatal broad, substigmatal fainter, yellow, traces of a line subven- trally, all more or less white spotted. Essentially as in the next stage. Stage V7.—Head and warts shining black, the latter bluish ; width 2.7 mm. Body deep black, the dorsal line broad, straight, narrowly broken in the incisures and centre of the segments, yellow, darker yellow or red in the centre of each segment, faint on joint 2. Traces of a sub- dorsal band, broken by wart it., whitish, mottled. Lateral band broad, indented by warts ii. and iv., broken into three or four spots on each segment by transverse black lines, yellow, irregularly stained with darker yellow, connected inferiorly by mottlings and dots with a narrow sub- stigmatal line which is yellow, mottled, broken and runs between warts iv. and v. Traces of a subventral line between warts v. and vi. on the base of each leg. Leg plates black. Venter broadly pale gray, blackish dotted. Hair very short, inconspicuous, black or black and white, stiff, pointed, not barbuled. In some individuals the subdorsal whitish dots are absent, and in some the dorsal band is distinctly marked with red ; otherwise there is very little variation. Corresponds well with Saunders’s description of reversa (CAN. Env, I., 20), and also with Riley’s of /advi- costa (Third Report Ins. Mo., 134). The forms co/ona and conscita have not been bred. 100 THE CANADIAN ENTOMOLOGIST. Explanation of Plate iv.

During the summer of 1896 I received specimens of ants collected by Mr. R. J. Crew, of Toronto, in exchange for such Coleoptera as I could find for him in my locality. He writes me that he noticed no insects with the ants other than the Coleoptera and some aphids in a nest of ants, but did not capture any. I have found, however, upon looking them over, they contain several very interesting species of various orders: some truly myrmecophilous, some occasional, while others were brought into the nests by the ants, to be used by them for food ; this will apply to a number of Hemiptera collected by Formica subsericea, Say. . It may appear to some who are collecting ants’-nests Coleoptera only that the finding of Agonoderus pallipes, Kabr., and Otiorhynchus oratus, 1.., is merely occasional. The position in which these Coleoptera are found with the ants here in Massachusetts, and the frequently finding them with various species of ants, lead me to believe that they are more than incidental or casual visitors. I am not familiar with the scattered literature treating upon the THE CANADIAN ENTOMOLOGIST. 101 Formicidz found in Canada. I will give, however, all that I know of, taken from Dr. Dalla Torre’s Catalogue of Hymenoptera, Vol. vii., 1891 : Stigmatomma binodosum, Prov. Pogonomyrmex badius, Latr. Leptothorax Canadensis, Prov. Dolichoderus borealis, Prov. Dolichoderus obliteratus, Scudd. Formica arcana, Scudd. Mr. Crew has not as yet found any of the above species at Toronto.

ENTOMOLOGICAL SOCIETY OF ONTARIO. We have great pleasure in announcing that a branch of our Society has recently been formed in the City of Quebec, with the following officers : President—Rev. T. W. Fyles, F. L. S., Professor of Biology in Morrin College. Vice-President—Miss Macdonald, Principal of the Girls’ High School. Secretary-Treasurer—Col. Crawford Lindsay. Council—Messrs. D. H. Greggie, Richard Turner, J. E. Treffry, Miss Bickell, Miss Winfield. With such an enthusiastic and experienced entomologist as the President, and such an able corps of officers, the Branch will no doubt do excellent work, and serve to unite together all those interested in this department of natural science in the neighbourhood of Quebec. We trust that the new Branch may have a long and useful career. The Toronto Branch of the Society held its first annual meeting on Friday, April 2nd, in its room, 451 Parliament street. The election of officers for the ensuing year resulted as follows : President—Mr. E. V. Rippon. Vice-President—Mr. R. J. Crew. Secretary-Treasurer—Mr. Arthur Gibson. Librarian-Curator—Mr. T. G. Priddey. Council—Messrs. C. T. Hill and C. H. Tyris. The reports of the Secretary-Treasurer and the Librarian-Curator for the past year were read and adopted. They stated that twenty-four regular meetings had been held, at which papers relating to the study of. insects were contributed by the members. The number of volumes in the library, including bulletins, pamphlets, etc., is 98, all relating to entomology, and all gifts to the Society. A fair collection of insects has already been formed through the kindness of members in presenting specimens, and will no doubt be largely increased during the coming season. The finances of the Society were shown by the Treasurer’s report to be in a satisfactory condition. , The President, in his address, congratulated the members on the good work done during the year, and on the success which had attended the Society’s operations. He hoped that during the coming season each member would take a special interest in some particular species of insect, and would endeavour to work out its life history ; he also trusted that much attention would be paid to the study of those species which are beneficial or injurious to mankind.

This genus is easily recognized among its neighbours by the fact that the eyes are divided by a deep emargination into an upper and a lower portion, these parts being connected only by a narrow band from which the granulations or lenses have been lost. The Canadian 7; cinnamopterum, Kirby, is brown, the wing-covers often much lighter than the head and thorax; the entire body is pubescent. Length .50—70 inch. The head and thorax are slightly shining, distinctly punctured, the punctures regular, usually close but distinctly separated. Elytra opaque or extremely feebly shining. Sculpture much finer than that of the pro- thorax. The sexes differ especially in the somewhat shorter antennz and the broader and more strongly rounded prothorax of the female. The species occurs on or under bark of pine logs. AsEMuUM, Esch. Two species are recorded from Canada. They are stout brown insects with short antennz (from about one-third to one-half the length of the body), elytra sometimes yellowish. The thorax is about as broad, in its widest part, as the base of the elytra; the punctuation coarse and close on the pronotum, much finer on the wing-covers. The prin- cipal differences separating the two forms must be looked for in the prothorax, which is rounded on the sides in mastum, Hald., and distinctly angulated near the base in atrum, Esch. The distinctness of the elytral coste seems an evanescent character, since certain specimens of the former species approach the latter very closely in that respect. In length A. mestum (fig. 16) ranges from .45 to .60 inch, while speci- — ‘F's. +6. mens of atrum are known which slightly exceed the greater measure- ment and others which scarcely reach the lesser. In the larval stage 4. mestum is known to infest pine and spruce, and the beetles may be found on lumber piles. CRIOCEPHALUS, Muls. Contains larger species than the preceding genus, with coarsely granulated eyes which are not hairy. The prothorax is variably sculptured, sometimes roughened and with deep impressions on the disk. 106 THE CANADIAN ENTOMOLOGIST. Two are recorded from our region. They are both rather elongate brown insects and separate thus: Thoracic impressions deep, elytra finely punctured, third joint of hind tarsi two-thirds longer than wide, emarginate for about one- half its length.

C. agrestis is known to depredate on pine and spruce. PHYSOCNEMUM, Hald. P. brevilineum, Say, is .50-.75 inch long, black, somewhat shining, elytra sometimes bluish or with a faint reddish tinge along the suture. The upper surface is uneven, the prothorax with deep median longi- tudinal impression which is convex at bottom and limited on each side by an elevation, which is smoother than the external thoracic margin. Elytra distinctly closely punctured and ornamented with a few narrow, short, raised white lines; the median region on each wing-cover is depressed and limited exteriorly by a smoother linear area, which extends from the humerus towards the apex. Thighs suddenly and strongly dilated near their tips. Hind legs very long. The larva is known as an elm borer. RHOPALOPUS, Muls. An easily recognized species, . sanguinicollis, Horn, belongs here. It has been found on cherry trees, Length .62-.75 inch, colour black opaque, surface granulate ; prothorax red, tips of elytra sometimes brownish. The thighs are less suddenly clavate than in Physocnemum, ~ and the tibize are stouter. The extreme shortness of the prothorax will separate it easily from most of its neighbours. GONOCALLUS, Lec. Differs from the adjoining genera by the slender thighs. G. cod/aris, Kirby, is black, shining, elytra sometimes with metallic lustre or clouded with fuscous, the prothorax red, legs sometimes reddish.

They are mostly flatter than Phymatodes, and with heavier antennee, especially in the male. The colour affords a primary means of separating them, C. ereum, Newm., being entirely testaceous or brown- ish, while antennatum, Newm., and janthinum, Lec., are metallic blue or green above. The last named has the thorax deeply punctured, not impressed, while in av¢ennatum impressions are present and the thoracic punctuation is finer. All the species vary much in size, ereum from .34 to .50 inch, while the others run from .25 to .55 inch, janthinum averaging a little smaller. It is reported ereum has been bred from chestnut, while aztennatum depredates on pine. 108 THE CANADIAN ENTOMOLOGIST. ——————— = — —— HyYLOTRUPES, Serv. The two species of this genus are very different in appearance. Af. bajulus, Linn., is blackish, pubescent above, more thickly on the pro- thorax, where the hair is whitish, almost covering the surface except on the elevated median line and the two raised callosities, which are thus ren- dered very conspicuous. ‘The elytra have two indistinct transverse fascize of whitish pubescence, one in front of the other behind the middle, the latter sometimes wanting. Length,.72 to.88 in. Depredates in pine and juniper. H. /igneus, Fabr., is extremely variable, the thorax usually black, less hairy than in da7u/us, and with five callosities. Elytra yellow- ish or reddish, with a large blackish blotch occupying usually the apical third, and an elliptical spot of the same colour but varying in size between this blotch and the base. Bores in juniper in the larval state, perhaps also in pine, as the beetle is found on piles of lumber or on freshly con- structed fences. Length, .30 to .45 inch. Merium, Kirby. M. proteus, Kirby, is .45 to .60 inch long, thorax metallic blue or violaceous, shorter than usual, varying in shape according to sex, densely punctured and rather opaque at sides, but shining and with only a few large punctures at middle. Elytra usually greenish metallic, densely and coarsely punctured, generally with two raised longitudinal yellowish lines before the middle, the side margin also yellowish in some specimens. Thighs reddish yellow, except at base and apex, which, with the tibie and tarsi, are blackish. Beneath shining black with a violaceous tint. CHION, Newm. Here belongs Chion cinctus, Drury, a large beetle of a brownish colour (fig. 18), sparsely clothed with whitish pubescence, each elytron usually with an oblique blotch of a yellowish colour near the base. The prothorax is nearly round, and bears a small spine on each side. The elytra are each bispinose at tip. The male antenne greatly exceed the body in length. The species reaches a size of from .75 to 1.5 inch. It is known to breed in hickory. The name gargani- cus, Fabr., catalogued as a variety, refers to the spotted form.

The two pairs of raised white spots (looking like Ichneumon eggs) on each elytron will easily serve to distinguish this genus. The only Canadian species is £. guadrigeminata, Say, which is of a yellowish colour, the thorax with sharp lateral spine and two distinct discal callosities. The elytra are bispinose at apex, the middle and hind femora have each two long spines at tip. ‘The ivory spots of the elytra are situated on the cost, the outer one of each pair being the larger, this difference in size being much better marked in the posterior pair. Length, .go—r1.20 inch. Breeds in hickory, ash, and honey locust. ROMALEUM, White. Contains two large species, among the most bulky of the Canadian Longhorns. Both are pubescent insects of robust build, the prothorax rounded at sides and without lateral spine, the elytra spinose at apex, tip of thighs unarmed, antenne spinose internally. 2. rufulum, Hald., is fulvous with uniform pubescence of the same colour. Length, .88-1.15 in. &. atomarium is darker, brownish,with irregularly mottled pubescence, and reaches a slightly larger size. It has been found under bark of walnut, while the larva has been bred up on hackberry. .° ELAPHIDION, Serv. The Canadian species of this genus are smaller and less robust than the preceding, and may be distinguished therefrom by that character alone. £. vil/osum is the well-known oak-pruner, and does, at times, considerable damage by ovipositing in twigs of oak trees, the larve then eating out the inner portion, so that the twig becomes weakened and may be blown off in a strong wind. Its depredations are not confined to oak, however, as Mr. Chittenden has recorded many other food plants. The table of species is an adaptation of the characters presented by Mr. Leng: A.

It has been bred from white birch. Puyton, Newm. A small pale insect, P. pallidum, Say, belongs here, and is perhaps doubtfully a true member of the Canadian fauna. It is a trifle under one-fourth of an inch long, of a yellowish colour, the prothorax broad in front of the middle, but narrowed in front and (much more so) behind, the surface with indefinite darker markings. Elytra with four oblique brownish bands, of which the one just behind the middle is broad, the remainder narrow. I have beaten it from palmetto blossoms in Louisiana. It has been bred from hickory and from Cercis canadensis. Fig. 22. OBRIUM, Serv. The only Canadian form is O. rubrum, Newm., which is one-fourth of an inch in length, shining reddish-testaceous, the head broader than the prothorax, which bears an obtuse dilatation each side near the middle, and has the base and apex nearly equal. The elytra are more closely punc- tured than the thorax. Thighs strongly clubbed. NOTES .ON PHILAINUS. BY CARL F. BAKER, AUBURN, ALABAMA.

Philenus lineatus, ..—I have a large series of this species from the North-eastern U. S,, the specimens of which are identical with the typical European form. It seems probable that true /zweatus is confined to the Eastern U.S. In American publications three distinct species have been confused under this name,—true /meatus, the didineatus of Say, and a new species from New England which I shall call americanus. The genus presents two types of elytral venation, one simple and regular, with three or four distinct apical cells, while in the other the elytra are distally irregularly reticulated. Lineatus, spumarius, campestris, exclamationis, etc., fall into the first group, while the second group appears to be strictly American, including adjectus, bilineatus and americanus.

It is a larger, more robust species than /iweatus, with the elytra broader in proportion to the width. The face is very much more strongly convex as viewed from the side than in Zémeatus. ‘There are also other minor differences.

KIRKLAND, ASSISTANT ENTOMOLOGIST TO THE GYPSY MOTH COMMITTEE, AMHERST, MASS. During the month of May, 1896, while making field observations in Malden and Medford, Mass., upon the insects known to attack the gypsy moth (Porthetria dispar), I found that many of the common predaceous bugs upon emerging from hibernation greedily availed them- selves of the food supply offered by the tent caterpillar and destroyed large numbers of this insect. odisus placidus, P. serieventris, P. modestus, Dendrocoris humeralis, Euschistus fissilis, E. tristigmus, E. ictericus, E. politus n. sp., Menecles insertus and Diplodus lividus were often found feeding upon partially grown tent caterpillars. Podvsus placidus and P. serieventris enter the tents and prey upon the inmates, but the other species generally attacked the larvae while they were feeding. The species of Auschistus are the least predaceous and it. is probable that they naturally feed more upon plants than upon insects. When feeding, these Pentatomids insert the sete only, and not the sheath, into the body of the caterpillar. I have watched them very carefully under a hand lens and my observations fully agree with those of Mr. Marlatt, as given in the Proceedings of the Entomological Society of Washington, Vol. II., p. 249. I have seen P. p/acidus extend its sete beyond the end of the beak to a distance equal to the length of the last rostral joint. When the sete are inserted in a strongly chitinized part the struggles of the larva often pull them from the sheath. In such cases the beak is drawn through the fore tarsi in the same manner that an ant cleans its antennz, and thus the sete are forced back into the sheath. I have also removed the sete of P. cynicus from the sheath by means of a fine needle applied along the labrum and have seen them replaced in the same manner. In the Report of the Massachusetts Board of Agriculture for 1896 I have published, with illustrations, notes on a part of the early stages and habits of some of these Heteroptera and the life history of P. p/acidus. This insect was first brought to the attention of entomologists through some very interesting notes published by Prof. Saunders in the CANADIAN Entomo.uocist, Vol. II., p. 15. The nymphs of this species, at first thought to be Stiretrus anchovago (Fab.) (fimbriatus, Say), were found attacking the larve of the currant sawfly, Pteronus ribesti (Scop.). Walsh, 116 THE CANADIAN ENTOMOLOGIST. *. = ——— on page 33 of the volume cited, corrects the identification and refers the insect to Podisus spinosus or modestus or to an allied species. Later specimens sent to Prof. Uhler (not Ulke) were found to represent a new species and were named Arma placidum (Can. Ent., Vol. IL, p. 93): Prof. Saunders also gives notes upon the predatory habits of this insect in the Report of the Entomological Society of Ontario, 1871, p. 31. I have been unable to find the original description of the species. Through correspondence with Prof. Uhler I learn that he cannot recall the circumstances connected with the publication of the description, were such a description published, and he has very kindly sent me the following characterization of the species together with a description of Euschistus politus : Podisus placidus, Uhler.—‘“ Of a narrower and nfore oval form than P. serieventris, with a head somewhat tapering anteriorly, and rounded at tip instead of being truncated, and with the humeral angles rounded off and very moderately prominent.

Other specimens have been sent to me for examination from Rhode Island, Pennsylvania, and the District of Columbia. I have found it once, July 4, in a sandy pine woods district in southern Maryland. Only a few specimens have thus far been reported. It seems to be of rather uncommon occurrence.” GRAPTA INTERROGATIONIS, BY ARTHUR J. SNYDER, N. EVANSTON, ILL. Under the title ‘‘ Notes on Vanessa Interrogationis,” in the February number of Can. Envt., Mr. W. F. Fiske gives some interesting statements corresponding to observations made here. I kept bait for moths on the trees in and near my yard from the beginning of the year 1896, and cap- tured Noctuids during January, February, and March. Diurnals came to the bait for the first time on April r2th. Vanessa Antiopa led the van, followed closely by the Graptas and Pyrameis Atalanta. In a few days /nterrogationis and Atalanta were abundant. Grapta Comma appeared on the 17th of April. April 24th I made the following note in my record: ‘ Previous to this date all the Grapta Jnterrogationis were hibernating specimens and of the form /aériciiz. This evening (my observations were made from four p.m. ’till dusk) all were of the dark form Umdrosa, but also all old hibernating specimens.” On the 25th both Umbrosa and Fadricii were seen. During the last of April and first part of May Graptas were exceedingly abundant. On May 7th saw the first Grapta depositing eggs on elm. Captured the ¢ and found it to be Umbrosa. A single butterfly procured from these eggs was of the form Umbrosa. Soon the eggs and larvee of Graptas were abundant on the elm trees and shrubs, especially on the low branches of young trees. One could hardly turn over a bough of one of these without finding several larve. 1 ; THE CANADIAN ENTOMOLOGIST. 119 Mr. Fiske came near proving a point concerning which many of us are interested, but the weak point is this: Did he examine the leaves of the branch of elm on which he netted the 2? Umdrosa? If not, how does he know that there were no eggs upon the limb at the time of con- fining the ? there? I have frequently found upon the same limb larve of Graptas in several stages of maturity, small ones just hatched, and others almost ready to pupate. I am inclined to think that Umdbrosa and Fabricii may be obtained from eggs laid by one 9, just as Mr. W. H. Edwards has succeeded in raising imagoes of Papilo Oregonia and Sairdii from eggs laid by a single individual. To prove these points just as we would have them, both sexes should be reared, each form paired with its kind, and wice versa, and the results noted. The second generation of specimens thus observed should settle the question. While I cannot positively answer Mr. Fiske’s question as to where the immense number of Umbrosa came from, the observations made here go to prove that the uncommon appearance of the species was not con- fined to one locality, but the ‘‘ wave” probably extended over the entire eastern United States. It is my opinion that the preceding autumn was an unusually favorable one for the Graptas, for both Umérosa and Fabricti were common here in August, 1895. Grapta Comma was very abundant here in the autumn of 1892, but did not appear in great numbers again until the spring of 1896. Papilio Ajax is very rare here in ordinary years, but in 1895 sud- denly great numbers of badly worn specimens appeared and remained for some days. Every collector captured examples, I think, but hardly any one secured a perfect specimen. _ The nearest point at which the food plant of 47ax is found, so far as I have been able to ascertain, is on the Michigan side of Lake Michigan. In this case the butterflies may have been carried from their usual haunts by winds. Insects undoubtedly migrate, sometimes suddenly and in immense numbers, as has been noted of Danais Archippus and Callidryas Eubule, and sometimes slowly, taking years to reach a certain locality hitherto unknown to thie species. Chrysophanus Helloides is moving eastward. A few years ago it 120 THE CANADIAN ENTOMOLOGIST. was considered a Rocky Mountain species, but lately specimens have been taken in Iowa, Illinois, and Indiana. Another question is why the form Faéricii should appear before OUmbrosa and then later on both forms appear at the same time? The broods of /nxterrogationis seem very irregular as to time of appearance, but there are at least two annual broods here. A NEW C@:LIOXYS FROM NEW MEXICO. BY T. D. A. COCKERELL, MESILLA, N. M.

Head rather large; vertex shining, with large, well-separated punctures ; mandibles bifid at ends, ferruginous except tips and extreme base ; antenne black, flagellum faintly rufescent beneath towards the end; mesothorax shining, with extremely large, well-separated punctures; a band of dull white pubes- cence at base of scutellum and a patch above base of wings ; scutellum shining and sparsely punctured, without any trace of a keel, rounded behind, with a very small tubercle at the middle (representing the median tooth of afgerta, etc.), lateral teeth large, flattened and rounded at tips ; enclosure of metathorax distinct, very finely granular, with a basal series of large pits; tegule apricot colour; wings dusky hyaline, the apical margin broadly smoky, nervures piceous, stigma fuscous, marginal cell more produced at tip than in a/fz/is ; coxe more or less darkened, legs otherwise entirely bright ferruginous, with the pubescence extremely scanty ; abdomen shining, segments 2-5 with transverse sublateral grooves ; punctures sparse, largest and densest at sides, rather small and numerous on dorsum of first segment, absent on dorsal middle of segments 2-5, except for an apical row and on 2 an imperfect basal one ; sixth segment with sparse minute punctures. Hair-bands very narrow and interrupted dorsally, so as to be inconspicuous. First segment except the extreme base entirely ferruginous ; second and third segments, and fourth more or less, ferruginous at sides ; venter ferruginous except apex. Apex with six teeth, of the terminal ones the lower are the longer. Hab.—Deming, N. M., at flowers of garden mint in Mrs. Bristol’s garden, July 9, 1896. (CkIl. B. 45.) Very distinct by the sparsely punctured (in parts impunctate) abdomen with its rufous first segment. Nearest, perhaps, to C. ¢exana, Cr. There is 2 Cedioxys taken by Prof. Townsend on the Gila R. in numbers, which I could not definitely identify. A specimen sent to Mr. Fox comes back marked ‘‘ near mesta.” Very possibly the species is new, but I do not at present care to give it a name, as there are several closely allied forms which I have not seen, and it may be one of them.
