One day last summer I received a letter from a physician in a town near Carbondale, stating that one of his patients had voided some live beetles, and asking me if I cared to see them. Assuring him that I did, he sent me several specimens of the species above mentioned. Not having this species in our collection, one of them was sent to Dr. F.M. Webster, Dept. of Agriculture, Washington, who identified it for me, but doubted its being an intestinal parasite.

A series of tables for the identificaiton of Rocky Mountain Coccidæ has been prepared for publication by the University of Colorado. Even now, while these tables await publication, I find myself obliged to add three new species, found here at Boulder; two of them representing genera new to our region. It is a rule of the University of Colorado publications that new species shall not appear for the first time therein, so I present herewith brief diagnoses of the three forms just mentioned.

This destructive enemy of the housekeeper is evidently rapidly widening the area in Canada within which it occurs as a household pest. Strange to say, the species has been found abundantly on flowers out of doors in some localities where it has never been noticed inside houses. Twentyfive years ago many specimens were sent to me by a collector from Frot Mc Leod, N-W. T., and specimens are found in entomological collections in all parts of the Dominion.

Stiria aliaga, n. sp.—♂. Expanse, 30 mm.

Ground colour even chrome-yellow, a shade lighter beyond t.p. line. Small ochraceous spot at inner thrid of cell, one towards its outer end and traces of one beyond. These are about equidistant from each other. T. p. line the only other marking on fore wing. This is quite faint, ochraceous, wavy and cannot be followed to costa in the speciments before me. The fringe is darker than wing, of a somewhat “Ashes of Roses” colour.

On September 4th I found, feeding on leaves of Nasturtium, two larvæ which I had never seen before, and which agree exactly with figures and descriptions of the larvæ of the “Large White Butterfly” of Europe, Pieris brassicœ

Proteoteras Moffatiana. n. sp.—Expanse of wings, 14—20 mm. Head, thorax and fore wings emerald green, varying considerably in the different specimens, some being much brighter than others. The fore wings are marked with black and much brighter than others. The fore wings are marked with blacks, and may parts have silvery reflections in certain lights. On the basal fourth of the costa there is a small quadrate black spot, below which the basal part of the wing is more or less marked with streaks or irrorations of black.

In collection insects of Poquonock, Conn., July 18, 1904, my assistant, Mr. B.H. Walden, found coccinellid larvæ feeding upon a species of Aleyrodes which is probably undescribed, and fairly common there upon the leaves of hazel, Corylus Americanus. These larvæ were brought to the laboratory, and were fed upon Aleyrodes vaporuriorum, Westw., which they ate greedily.

Of the ten superfamilies recognized in my classification of the Hymenoptera, all have been classified down to genera except the Ants, or superfamily IV, Formicoidea, a very large and most difficult complex, and rendered even more difficult by the extraordinary number and diversity of the sexes, there being sometimes several different forms to a single species.

373. Cosmia discolor, Walk.—(paleacea, Esp., of North American authors, in error.) Common in 1903, ♂ ♂ Aug. 31st to Sept. 23rd; ♀, only one observed, Sept. 7th. A single specimen only (♂) taken previously, in 1895. A few during 1904. Treacle.

For over three years we have had in the collection at Ottawa specimens of a pretty little Yponomeutid moth, which we have been unable to get identified.

Larvæ were first observed by the writer at Aylmer, Que., on May 24th, 1901. They were found feeding on stinging nettle (Urtica gracilis, Ait.). and appeared to be fairly abundant in one locality. Specimens collected on this date spun up within two or three days, and the moths emerged on June 7.

The following new species of mosquitoes have been found in New Jersey during the present summer (1905) in the course of the investigation conducted by Dr. John B. Smith.

Culex pallidohirta, sp. nov. ♀.— Head brown, occiput clothed with yellowish scales and a few dark brown ones intermixed; antenn♀ brown, the basal joint and basal half of following one dirty yellow; proboscis brown, with whitish scales scattered over the surfae save at the apical fourth; palpi brown, tipped with silvery white, four jointedm apical joint minute, flattened, spiny.

Diastictis argyralis, Hbn.— Beulah, IX, 14.

Nomophila noctuella, Schiff.—Cartwright.

Loxostege chortalis, Grt.— Aweme, VI, 6, to VI, 19; Souris.

Diasemia plumbosignalis, Fern.— Aweme, VII, 1; Souris; Wattsview.

Some of the generic names used for Scatophagid♀ will stand of fall according to one's notion of homonymy. Becker, in 1894, proposed the name Orthacheta (cf. Inded Zoologicus); Aldrich, in the interest of orthography, has altered this (Cat. N. A. Diptera) to Orthochœta. Now, Germar long ago used Orthochœtes for a beetle, while Cossmann, in 1890, used Orthochetus for a mollusc. I do not pretend to say what ought to be done with such a mix-up; it comes back to the old question, whether an error in spelling (which may hypothetically be attributed to the printer) must be maintained; and again, if not, whether the differences in the termination suffice to prevent homonymy.

Exentera apriliana, Grote.—Aweme, IV, 30, to V, 21; Beulah. Thirteen specimens. This is a particularly interesting caputre. Grote's descripiton is remarkably brief, and his generic description, occurring on the same page, is misleading on account of an error. He states: “Hind wings 7-veined, 5 wanting.” I know of no Tortricid genus in which 5 is absent; frequently 3 and 4 are coincident or stalked for their entire length, but even this is not the case in any one of these specimens; 3 and 4 are stalked from a quarter to a half.

Dr. Harrison G. Dyar, in the Proceedings of the Entomological Society of Washington, VI., No. 4 has given us a very interesting and important paper on the Hulst collection of Geometridœ.

In this paper he has shown, from an examination of the type specimens, that a considerable number of Dr. Hulst's supposed species are not really entitled to specific rank. Of course, any entomologist describing as freely as Dr. Hulst did would be sure to make some mistakes and create some synonyms, and I have no doubt that Dr. Dyar is prefectly correct in his judgment in the majority of cases that he cites.

Several entomologists have discussed with me the question of the distinguishing characters of Ranatra quadridentata, Stal, and Ranatra fusca, Pal. Beauv., and in consequence I venture to set forth here briefly and plainly the differences between these two and Ranatra kirkaldyi, n. sp, which I took for the first time in New York State.

Among the mosquitoes lately sent from the various Army Stations are the following, of interest mostly because of their apparent close relation to already known forms:

Uranotœnia cœruleocephala, Theob., var. lateralis, n. var.— ♀. Head covered with flat blue scales, becoming white around the eyes, a couple of brown bristles between, and a few around, the eyes, no fork scales; the scales on the occiput change from a dark indigo or violet to a light blue, according to the direction of the light, and when viewed from the side may even seem brown with a wide white border around the eyes, but in other positions are some shade of blue; antenn♀ brown, verticels and pubescence brown, basal joint light testaceous, with a few thin flat scales; palpi also light brown, very short, hardly longer than the depth of the clypeus, the last joint reduced to a knob; proboscis dark brown, swollen at the tip; clypeus testaceous; eyes brown and silver.

♀.— Length nearly 19 mm.; length of anterior wing about 13 mm.; breadth of abdomen in middle 7 mm.; in all respects like M. Comanche, Cresson (co-type compared), except as folllows: Abdomen broader; fourth segment without a bare median area, the braod grayish-white band continued right across; fifth and sixth segments with the hari purplish-black, except the long hair at sides, which is paler and redder; hair of venter not so red; hair of inner side of basal joint of hind tarsi reddish-black, ferruginous basally: wings hardly so dark; hair-patch on mesothorax shorter, so that it is conspicuously broader than long; flagellum dark, with only a faint red tinge beneath; hair on outer side of basal joint of middle tarsi brownish-black (rufo-fulvous in Comanche).

For many years I have collected diurnal Lepidoptera in the neighbourhood of Albany, N.Y., making a special study of established varieties, sports and minor vatieties within the species.

Among the Lycœnidœ the forms which have proved of greatest interest from this point of view are those afforded abundant material for investigation, and I.irus in particular has afforded abundant material for investigation, and long ago I was enabled to recognize several tendencies in the distribution of colour over both the wings and body, which made it possible to separate this species into groups or form-series.
