Neonympha sosybiuSj Fab. 
The eggs of this species are found on grass in July. The larva 
when first hatched is .09 of an inch long; color white, and marked 
by tuberculated longitudinal ridges; from each tubercle proceeds a 
clubbed white hair. Head large, shining black, bilobed. It molts 
four times, changing slightly in color, sometimes greenish, some¬ 
times bluish; when full grown it is .75 of an inch long; of an 
emerald-green color, fleshy, thickest in the middle, tapering more 
decidedly posteriorly, with forked, divergent tails at the posterior 
extremity; the segments are creased transversely, and the ridges so 
caused are covered with fine yellow tubercles; also larger tubercles 
arranged in longitudinal rows, each emitting a short line white hair, 
a clear dark-green stripe on the back, on each side of this a tuber¬ 
culated stripe, and another at the edge of the dorsum. Head rather 
large, broad and bilobed, slightly depressed at the suture, somewhat 
flattened in front, covered with fine conical yellow points, arranged 
in longitudinal and at the same time transverse rows; ocelli black; 
mandibles brown. Feeds on grass. 
Chrysalis, green; neuration of wings distinctly seen; length of 
Chrysalis state, thirteen days; the butteriiies appear the first of 
September. 
Neonympha canthus, Linn. 
This larva also feeds on grass, but I have no description of it at 
hand. 
Neonympha gemma, Hub. 
The larva of this species may be found in April, August and 
October; the young larva measuring .12 of an inch; somewhat 
spindle-shaped, tapering from the eighth segment, and ending in 
two divergent tails, which are thickest at the base and taper to. a 
blunt point, from each point proceeds a white bristle; color white 
at first but changing to greenish; striped longitudinally with white. 
Head blackish-brown, from the corners of which proceed two pointed 
horns of the same color, each emitting one or two bristles; these 
horns seem to be in three sections, each smaller than the one 
below it. The full-grown larva measures .75 of an inch to the tips 
of the horns, these being almost on a level with the body, the face 
being bent downward toward the body; the larvae of the different 
broods vary somewhat in color, from reddish-buff to yellowish'green; 
they have a dark dorsal line; in the summer and fall broods, this 
line is dark-brown, and in the spring brood, dark-green; in the 
former, an interrupted dark-brown line on each side of the dorsal; 
a dark-brown stripe along each side of the body; face and horns 
brown. Feeds on grass. , 
Chrysalis suspended from a white button of silk; yellowish, head 
case truncated and ending in two long three-sided palpi cases.
