PSYCHOMORPHA EPIMENIS. Drury. 
Ground color of larva white, banded 
transversely with four black stripes 
on each segment. The contrast of 
the black and white gives it a bluish 
appearance. The third and fourth 
stripes are usually farther apart than 
the other two, diverging on the sides 
to admit of two or more dark dots, placed one below the other. 
The eleventh segment has an elevation or hump, which, with the 
conical shield, anal plate, venter and legs, is dull, pale orange; all 
are marked with black spots, and the true legs are tipped with 
black; head, reddish yellow, inclined to orange, with eight principal 
and other minor black spots; venter pale, mottled with dark, and 
rows of spots on the leg joints. The stomata are round and quite 
small. Average length about one inch. 
Feeds on the Grape-vine and Trumpet-creeper (.Bignonia raclicans). 
Chrysalis reddish-brown, .37 of an inch long, rough ; apex truncated 
with a large ear-like projection from each upper and outer edge. 
Eudryas grata, Fabr. 
According to Riley, the ground 
color of the larva is more or less 
bluish. Six irregular transverse 
bands to each joint, and about 
eighteen piliferous spots, six above 
and six each side, substigmatal; 
several additional black specks, the 
two middle stripes farthest apart,

sections. orange. Head yellow, with nine 
black piliferous spots to each cheek; the upper one is accompanied 
by one or two black specks; also six such spots in pairs around 
the epistomal suture; there are also two on labrum, two on men- 
tum, two on cardinal piece of maxillae, and several on the legs. 
The stripes varying much in thickness, and the spots in size and 
conspicuity. The orange frequently quite deep, inclining to fulvous. 
The hairs from some of the spots quite obsolete, and not generally 
longer than the orange bands. When young, the color is pale 
yellowish-green, with no black bands and no spots on the head. 
Length, 1.5 inches. 
Eudryas unio, Hubn. 
The larva is similar to the above, and, according to Riley, the 
two species cannot, with certainty, be distinguished unless it be by 
the smaller size, the lesser prominence of the hump, and greater 
paleness medio-ventrally in unio. 
Mr. Lintner makes a list of differences from which the following 
is taken—two unios , six grata: 
The unio larva alcoholic specimens average 1.05 inches in length; 
the grata 1.29. Unio is the more heavily marked with black, both 
in its bands and dots. In none of the examples of grata are the
