Lygus Chagnoni, n. sp.— This species of the genus Lygus is of a form near to L. pabulinus, Linn., in appearance.

It is ovate, convex bright green in living specimens, with irregular purplish-brown markings at the base of the membrane, smooth and without bristles, and a silky pubesecence on the sides of the pronotum, which has an orange-yellow border next the head, shading backwards in narrow lines into the green coloration, so as to make the reen appear in broad bands.

I have postponed replying to Mr. Bacot's communication (Can Ent., XXXV., 44–47) until I could examine his preparations. He has kindly sent them to me, and they seem definitely to settle the two points that remain at issue. The Agliatau is in fluid, and shows a number fo secondary setæ as described by Mr. Bacto. These setæ are short and unusally weak, so that in my own specimen, which is dried, inflated they had become partly shrivelled, partly broken in transit. I do not think, after examining Mr. Bacot's specimen, that they can be regarded otherwise than as true setæ, and I am very willing to acknowledge myself corrected. This correction, if applied to my synoptic table of Saturnian genera (Tutt, Brit, Lep., III., 272), makes my division stronger and sharper than before, allying Aglia more strongly than ever with Attacus and Saturnia.

The members of the Association of Economic Entomologists and the local Entomologists of Washington connected with the Entomological Society of Washington, at the conclusion of the meeting of the first-named Association, met in an informal reunion and smoker at the residence of Mr. Wm. H. Ashmead, on the evening of December 27th 1902. At this meeting the subject, first broached in the concluding session of the Association of Economic Entomologists, of reviving the Entomological Club of the A. A. A. S. was considered, and in the absence of the last President of the Club, the Rev. C.J.S. Bethune, Mr. Schwarz was made Chairman of the meeting for the purposes of this discussion. A general desire was manifested on the part of those present to have the Entomological Club revived or some other similar organization instituted.

The wasps belonging to this family, on account of the emarginate eyes in the females, and the abdomen being usually marked with yellow or white, closely resembles those in the families Myzinidæ and, scoliidæ, butmay be easily distinguished by the great difference in the legs, the middle coxæ being approximate, the outer face of the tibiæ being smooth,unarmed, without tubercles or spines, while the tarsi are without strong spines or bristles, and unfitted for digging.

Crioceris12-punctata, Linn, is an introduced species, and has been working northward from Maryland, according to Professor J.B. Smith, who some time ago informed me that it was present in New Jersey, and would in time reach Connecticut. The first speciment recorded from the State was taken by a student assistant June, 16th, 1902, who collected a single speciment on asparagus upon the Station grounds in New Haven. On May 23rd, 1903, I took male and female specimens from the same locality. We may now expect this species to become thoroughly established here as a pest of asparagus, beetle, C. asparagi, Linn.

In a collection of Diptera, taken in Arizona by J. Thomas Lloyd, of Cincinnati, Ohio, during the summer of 1902, I find some species of sufficient importance to warrant recording notes concerning them at this time.

Chrysops proclivis, O.S.—Specimens of this species were taken in Oak Creek Canyon, July 5th. I have not seen a record of the species from this territory heretofore.

I am hardly prepaled at present to accept Isodontia elegans, Smith, as a variety of I. apicalis, Smith. The differences between the two seem to be very constant, and their distribution appears to be somewhat different, elegans being more a southern and western form, while apicalis occurs chiefly in the central, eastern and northern States.

Feralia Columbiana, n. sp.—Ground colour a bright emerald green, the maculation black and white. Head with a black interantennal spot. Collar with a black patch at its centre and at the base of each primary: tipped with whitish. Behind the collar there is a black edging to the disc and the loose basal tuftings are black marked. The edges of the patagia are black along the disc and at the base of the wings. The thorax itself is small and quadrate, the maculation just described forminga black square in its centre. The abdomen is deep smoky brown,yellowish or whitish at tip. Primaries with all the lines black, prominent, yet fragmentary. Basal line single, accompanied by a few white scales, becoming diffuse at the inner margin. T. a. line single, followed by a white line, out curved as a whole and irregularly bent or curved outwardly in the interspaces.

Mr. Washbrun's note in the November number (p. 320) induces me to state the Gastrophilus epilepsalis, French, is no Gastrophilus at all; in fact, not the larva of an Œstrid. The figure shows that it is a Muscid larva, very probably of Calliphora, certainly so if the figure is correct. The species cannot be identified untill more of these forms are reared. French's figure indicates that it is very close to the European C. vomitoria as figured by Pipers. There is no definite character known to identify Œstrid larvæ of some Muscidæ can be separated from the Œstridæ.

Leconte and Horn, in their “Classification,” say of this beetle: “It is of such extreme rarity as to have been by but few entomologists.” It was with considerable interest, therefore, that I captured my first specimen one March afternoon in 1894. I came upon Æ. debilis on the under side of a stone. From Leconte'e description I felt prety sure that my identification was correct, and it was subsequently confirmed by Dr.Fletcher, or Ottawa. Leconte says the beetle is black, but he had probably seen only dried specimens. Freshly-taken specimens show a distinctly green tinge. The insect is about .15inch long, and in general shape suggests a small carabid.

Since the majority of the Entomologists present at this meeting belong to a younger generation, who have never attened any ot the meetings of the old Entomological Club of the A. A. A. S, a short history of the Club may not be out of place on this occasion. These notes I have prepared from a hasty persual of the most readily available entomological literature, and more especially from the volumes of the Canadian Entomologist, to which periodical the Club is deeply indebted for the faithful preservation of its records through a long number of years.

William E. Leach, and not Frederick Smith, Ernest André has it, was the first to establish the family Mutillidœ but none of these gentlemen correctly defined it, and all have included genera which do not belong to it. Some of the genera belong to the Bethylidœ, one belongs to the Thynnidœ, one to the Cosilidœ, and others to the Myrmosidœ.

I have spent more time than I like to think about identifying bees of the genus Megachile, so I have no apology to make for offering somenotes which will, I hope, make the process easier for others:

Megachile frugalis, Cresson.— This species was described from the male. I have before me a female collected by Dr. Davidson at Lancester, California. It practically agrees with the description of M. zaptlana, Cresson, ♀, except that it has no lines of white pubescence on the thorax. M. occidentalis, Fox, ♀, is very similar, and has the lines of white pubescence, but it has a different clypeal margin, and the very scanty hair on the disc of the clypeus is white. In M. frugalis, ♀, the clypeus has long black hair; the ventral scopa is creamy white, black on the last segment. These bees are all of the elongate narrow type. The anterior margin of the clypeus in frugalis, ♀, can hardly be called excavated, but presents three gently-rounded prominences, the margin between them being slightly concave.

In studying the larva and pupa of Steganoptycha pyricolana, Murt., some observations were made as to structure, which it seems desirable to permanently record. The life-history and habits of the species have been described in the Twelfth Report of the Delaware Agricultural Experiment Station.

“This species was described by Miss M, E. Murtfeldt, in Bulletin No. 23, o. s., Div. Ent., U. S. Dept. Ag.., p. 52, as S. pyricolana, Riley MS. Concerning the identity, it was stated that ‘Professor Fernald, to whom a specimen was shown, considers it identical with Clemens's S. salicicolana, which, I believe, breeds in willow galls, but Dr. Riley pronounces it distinct, and he has types of Clemens's species.’ My specimens agree entirely with Miss Murtfeldt's description, but are distinctly different from Clemens's types in the collection of the Am. Ent. Society. Correspondence shows that the opinion credited above to Dr. Fernald is incorrect, as he never compared the specimens.

The members of this section of Club are endeavoring to create a more active interest in the study of entomology by holding fortnightly meetings, at the residences of the members, for the exhibition of specimens, discussion thereon, and the presentation of brief papers. The movement has so far proved most satisfactory, and the benefit of it has been felt by every individual, in reviving and quickening their love for the subject, and in affording opprtunity for solving of problems which every collector meets with in examining insects which he has not specially stuided. Three meetings have already been held; the first at the residence of Dr. Flecther, who was the principal mover in organizing the meetings; the second at Mr. Harrington's and the third at Mr.Hulkett's. They were all most enjoyable and instructive, and the two hours allotted to each were fully occupied, and the discussions and exhibits will undoubtedly bear fruit in improved work in future by the members. They also look forward to more systematic collecting in the approaching season, and to the holding of more frequent sub-excurisions.

The genus Lepidosaphes was established by Dr. Shimer, in the Transactions of the American Entomological Society, Vol. I., p. 372, Jan., 1868, with one species (conchiformis =ulmi, Linn., 1758). Although the generic description is not all that could be desired, it is certainly more satisfactory than the descriptions of many genera of insects in this and other orders which have been accepted without question.

The generic name Mytilaspis was first published, without a word of description, by Signoret, in his Catalogue of the Coccidæ in the Annales de la Societe Entomologique de France (4), Vol VIII., p. 841 (1868). This paper was presented to the Society at the Seance of March 25th, but was not published till later in the year. A description of this genus was given by Signoret in the above-named work for 1870, page 91. This article was presented to the Society at the same time as the Catalogue.

The genus Corethra was founded by Meigen in 1803,* on Tipula culiciformis, De Geer, and in April, 1844, Leow erected the genus Mochlonyx† on Corethra velutina, Ruthe, basing it on the shortened first joint of the tarsi, a character mentioned by Ruthe in his original description. The characters of the tarsi of culiciformis cannot be ascertained from De Geer's description and figures.‡ On page 386 of the same volume of his Memories, which contains the account of this species, is a description and brief account of a related species, which he named Tipula crystallina, with a reference to Reaumur's Memories, V., plate 6, figures 4–15, where at 4 and 7, a more slender larva without a trace of a subanal respiratory tube in shown, contrasting with the broader larva furnished with a large respiratory tube, as represented in De Geer's figures of culiciformis,; the descriptions and figures which these authors give crystallina do not indicate the characters of the tarsal joints of the adult.

The first paper of this series is in the January number of this Journal (pp. 9–14); the second is in the April issue of the Journal of the New York Entomological Society. The present instalment deals chiefly with species found in the Western Provinces of British America and a few others that are likely to occur there. The determination of a new species of Rancora from Calgary and Manitoba makes some general remarks on that genus timely. There is a number of excellent collectors now hard at work on th Noctuid fauna of that general region an extending westward to Vancouver, whose work deserves the greatest praise and to whose efforts is due the development of a totally new faunal region for this family of moths.
