After First Moult.—Length .45 inch. Cylindrical, head with an elevated point upwards, in subpyramidal point, the top in two points and about a third higher than the body; when at rest the jaws under back part of head with the point obliquely forward. Eight transverse wrinkles to each joint; green studded with pale green points; a subdorsal pale line, as usual converging to caudal horn; on sides, oblique pale lines that nearly coincide with a series on the dorusm; the plae parts yellowish green; caudal horn reddish tinted; head with a pale stripe on each side of face, the two coming together above.

The genus Pseudohazis, Gr.& R., has only two typical representatives so far known, one being Eglanterina, Bd., with the purple colouring, and the other the white Hera, Harr., from Utah's salt regions. Hera has to be considered a distinct species, for, aside from its white colour, its primaries are falcated, while those of Eglanterina are broad and blunt. All the rest of named insects are variations of Eglanterina,“Pica, Walk., being especially recognizable by its heavy black markings and black basal areas.

It is forty years ago since Lederer used the male genitalia to group the European species of Agrotis. According to the latest general work on the subject, the 127 European species of Agrotus fall into nine groups, characterized chiefly by changes in the form of teh male genitalic appendages. The failure to correlate these European groups with the American subdivisions of Agrotis, prevents me from considering Prof. Smith's recent revision as complete, since I have demonstarted the near relation between the two faunæ exhibited by Noctuinœ of the Old and New World.

On Dec. 14, 1890, I secured from the upper Piney Branch region (District of Columbia) a small quantity of swine dung that had been dropped in the edge of open woods, and seemed to be old enough to contain with probability larvæ or puparia of Diptera. This was placed in a large glass jar, with a few inches of sand in the bottom, occasionally moistened and kept in a moderately cool room in the house. The dung was soon noticed to be full of larvæ which in a short time crawled out of it entirely, cluseterd on the inside of the glass, or worked themselves down into the sand, manifesting a considerable migratory instinct, no doubt induced by the moisture and mild tempearture.

The moths bred from the larvæ here described were kindly determined for me by Prof. J.B. Smith.

Tœniocampa alia, Guen.

Stage I.—Head shiny, pale yellow; mouth orange; ocelli black; width, .3 mm. The abdominal feet are well developed only on joints 9, 10 and 13, so the larva walks like a Geometrid. Body whitish, appearing green from the food within, with many black, piliferous dots. Joint 12 is a little enlarged; cervical shield coloured like the head, but paler, Length, 4 mm. This larva was found May 3.

Mr. Dyar's note and Mr. Grote's reply, concerning the identity of the above species with specularis, H. S., may make further notes interesting. Mr. Hy. Edwards informed me two or three years ago that Mr. Grote had redescribed Herrich-Shaeffer's species, and that he had a specimen. I suggested that he should print this note, and he promised to do so in connection with a number of other remarks on Bombycid species.
