Egg.—Similar to D. ministra; cannot be distinguished from it. Laid in masses on the under side of leaf.

Young Larva, after First and Second Moults.—Cannot be distinguished from D. ministra.

After Third Moult.—Little change except in size. The stripes are now confluent about the anal segments. Length 30 mm.

After Fourth Moult.—Head jet black, cervical shield now chestnut brown instead of black; otherwise as in D. ministra. Length 40 m.m.

Mr. Grote takes occasion in Can. Ent. vol. xx., p. 168, to criticise my reference to Cerathosia to the Arctiidœ, contending that it is a Noctuid. He complains that I do not give “the reason why it belongs to the family.” This I hasten to supply, and must beg Mr. Grote's pardon for having presumed him conversant with the characters separating the two families. All authorities give for the Noctuidœ a furcate dorsal or internal vein of primaries, while the costal vein of secondaries is from the root, sometimes united with the sub-costal a short distance from base.

Egg.—Fusiform, thick in the middle and tapering to a small rounded summit marked by about sixteen longitudinal ribs, which are low, narrow, flat and crossed by a few fine ridges. Color yellow-brown. Duration about fifteen days.

Young Larva.—About .8 inch in length, cylindrical, slender; shape like the other Arzamas. Color pale green, with a few long hairs proceeding backwards. Duration eighteen to twenty days.

Anthocharis Pima

Male—Expands 1.75 inch.

Upper side yellow; the bases of wings dusted black; primaries have the basal half of costa white, crossed by dark brown streaks; the apex also edged white on both margins, and next this is series of five large, elongated, dark brown spots, almost confluent, filling the interspaces to second medium nervule, each sending a narrow projection to the margin; on the arc of black rectangular bar, the area between this and the apical spots and costal edge orange; fringes whitish; a few blackish hairs at the end of eacch nervule on secondaries.

This is in California the first buttefly to emerge in the spring, appearing in Feburary, though it is accepted representative of the Eastern Neglecta, which is not the first to appear there. Piasus is double brooded; the second brood coming in the latter part of April, and between it and the first brood a few days intervene when no Piasus are seen. Both broods are very fond of water, being always found on damp sands of wet places, and at the bookside crossings.

Botis magistralis, Grote.

Head pale brown, smooth, shining; mouth parts dark brown; cervical shield brown, divided in the middle by the color of the body, which is translucent greenish-white; along the dorsal region two rows of shining pale brown piliferous spots, four on each segment, those on the first segment darker in color. All the spots bear a short light brown hair. Thoracic feet, abdominal and anal legs concolorous with the body. Length 30 mm. Lives singly on Clethra alnifolia, in a number of leaves fastened together with silken threads. Pupated July 6th. Imagos emerged July 17th and 18th.

My last paper in the Proceedings of the Am. Philosophical Society, Philadelphia, contains a number of typographical errors, the most serious of which I corrected subsequently by an “errata” in a later volume, not being able to see the proofs. This paper reviewed the main and first two groups, leaving the Fasciatæ (Catocalinæ Pack.) and the Deltoids unrevised. I would recognise five very unequal groups both in structural value an extent. Adopting Packard's nomenclature so far as he went (this author excluded the Deltoids at the time), we may call these groups subfamilies, but in Europe my Thyatiridœ and the Brephidœ are taken out of the Noctuidœ as distinct families.

Datana integerrima, Gr. & Rob.

Before Last Moult.—Head and cervical shield shining jet black. Body deep reddish brown, with three very fine, narrow, sordid white stripes along each side, and a broader one below the spricles, which are black, and another stripe along the middle of the venter. Thoracic feet, extremities of abdominal legs and anal legs jet black, shining. The body is also covered with sordid white hairs. Length 32 mm.

It has occured to me to say a few words upon the subject of author's types. It sometimes happens that a specimen is labelled “type,” which is not the true type, i. e., the one (or ones) from which the original description was drawn up and which accords with that description. This is the criterion for types, that they do not contradict the original description. The late Mr. Morrison sent me at one time a “type” of Harris's Agrotis tessellata. Upon my wonder at his having such a specimen, I found it was merely a compared example, but it shold not have been labelled “type”.

I wish to draw particular attention to this genus and its allies. I have, in 1865, drawn a parallel between the group and the Hawk Moths, from the young stages and the peculiar pupation, and in my pamphlet on “the Hawk Moths of North America,” I hae discussed the probabilities of their relationship. But I here wish to point out that the group is American; that in America we may except to find old types among that portion of the fauna which is indigenous, pre-tertiary, and to this Citrheronia belongs.

Egg.—Pure white, ovoid, with flattened base the apex with black dot showing impregnation. Laid in masses, from 25 to 50 on under side of leaf.

Young Larva.—Head black, shining, second segment orange brown in front, cervical shield black. Body color chestnut brown, with the stripes a little darker; anal clasps and thoracic feet jet black. Length 3 mm.

Yellowish, slender faintly villous; face yellow; between the antennæ and a little above, a longitudinal median line, connected with a transversal one on the epistom, all black; palpi equal, pale, the apical joint of maxillary and this of labial, which is very little thickened in the basal half, somewhat brownish; antennæ longer than head and prothorax, in the male fuscous annulated with luteous, especially before the tip, which is clavate; shorter, more clavate in female; the two basal joints brown, shining; vertex elevated, rounded, yellowish with two blackish dots; prothorax little longer than broad, yellowish, with two dorsal black lines, ending on the anterior transversal sulcus; sometimes a darker spot in front of the lines; on each side and nearly below a black band connected with the lateral one of the thorax; two black maculose bands including yellow spots on the thorax; two black maculose bands including yellow spots on the thorax; mesothorax before wings black, with yellow spots; abdomen of male much longer than wings, faintly villous yellow, with a fine black median line, apical part blackish, yellow on articulation and some lateral marks; appendages less than half the length of last segment, cylindrical, yellowish, brown at abse, densely clothed with black hairs; below and between them a small triangular yellow plate;

We are requested to announce that the next meeting of the Club will be held at Cleveland, Ohio in the High School Building, beginning at 9 a.m., on Wednesday, the 15th of August. This date is a week earlier than that at first decided upon for the meeting of the A.A.A.S. As this location is central and convenient alike for both United States an Ontario Entomologists, it is expected that there will be a large attendence, and an interesting and enthusiastic meeting. All entomologists are requested to come prepared to aid in the matter; those who desire to present papers should send to the Secretary, Prof. A.J. Cook, Agricultural College, Mich., the subject they propose to discuss in order that it may be announced in the programme.
