130 PSYCHE. [October 1897.
cell ; the transverse cubital veins are usually subangulately broken with more or less of a distinct stump of a vein issuing from the angle (the right wing has the third submar- ginal cell nearly divided into two cells by a spurious cross-vein from the angulation in the second transverse cubitus). Abdomen apparently smooth, impunctate, but with a etrong lens thesurface exhibits a fine or microscopical reticulation from very fine lines.

Type, No. 3716, U. S. N. M.
. This species is allied to A. occiifentalis Cr. hut is readily distinguished by its smaller size, the color of the wings, by the venation and by the smoothness of the mesonotum.
Its resemblance to A. iwicolor Say. is only superficial.
The species has been named in honor
of Dr. Leuthstrom, father-in-law of Prof. Peckham, in whose garden the species was fonnd.

Length 3 to 3.5 rnm.
Black, closely punc-
tate and clothed with a sparse whitish pube- scence, the face from middle of eyes and the clypeus with a dense silvery pubescence. Clypeus with a median ridge and produced . -
into a. small conic median tooth at apex. Mandibles black, the basal two-thirds closely opaquely punctate, the apical half smooth, shining. Palpi brown-black. Antennae 13- jointed, the flagellum gradually incrassated towards tip ; the first joint of the flagellum is scarcely as long as the second, the third and fourth a little longer than the second and stouter, the joints beyond to the 13th gradu- ally shortening, joints 7-10 being transverse; the terminal joint is large, conic-ovate, as long as the three preceding united. Metathorax rugulose with two short median carinae in a slight depression just before the posterior face. Wings hyaline, faintly dusky at apical margins, the tegulac, stigma und veins brnwn- black, the marginal cell is subfanceolate with the extreme apex truncate and with an appendage; the second submarginal cell is triangular, petiolate, the second recurrent neivure entering it a little beyond the mid- dle. Hind tibia! spurs and the three basal joints of tarsi, whitish. Abdomen long,
ovate, a little longer than the head and . thorax united, subopaque, finely punctate, sericeous, except lateral triangular spaces, , separated by a grooved line, on second, third and fourth dorsal segments, which are smooth and shining

Quite distinct from all other species de- scribed in this genus by Mr. Fox, by the apical median clypeal tooth.
Prof. Peckham informs me this species
preys upon a Lygaeid belonging to the
genus Pamera.
THE LARVA OF CYDOSIA.
It will be remembered by lepidopterists
that the position of the genus Cydosia
Westw., has been in dispute. In Smith's list of 1891, it appears in a subfanlily Cydosiinae of Arctiidae. I have just learned from my friend Mrs. E. M. Swainson that she has
discovered the larva in Jamaica, and she s.ends me some notes on the subject, along with a specimen of the moth. ' The particular spe- cies sent - the only one known to occur in Jamaica- is C. s~tbmwtata (Walk.) Ckll., Journ. Inst. Jamaica, 1893, p. ajg (= C. famaicensis Ckll., Journ. Inst. Jamaica, 1892, p. 135, = C. nobilitella (not Cram.) Butler ex err., P. Z. S., 1878, p. 495). I give the account of the larva in Mrs. Swainson's own words : - "A pretly half looper larva, one inch and a half long, soft velvety black with orange marks all down back and at sides, between these are tiny pale yellow marks, on
