BUTTERFLIES OF MAINE. 99 
The eggs of this grass-feeding species are of a pale yellow- 
ish green color, strongly convex above, and with the base 
flattened. The surface appears smooth under a lens, but 
faintly reticulated under a power of eighty diameters. They 
hatch in eight or ten days, and the young larva is one tenth 
of an inch long, with a large, shining black head, and a white 
body tinged with yellowish brown which is more apparent 
towards the hinder part. 
The full grown larva is one inch long, of an oval outline 
something like a ‘* wood louse” or “sow bug” in form. 
The head is not large in proportion to the size of the body, 
but prominent and much larger than the second segment; of 
a dull reddish brown color, edged with black on the hinder 
part, and clothed with minute whitish hairs. The body 
*is dull brownish green, with hairs similar to those on the 
head, and a line along the middle of the back, and numerous 
dots over the surface of the body of a darker shade. The 
second segment is pale whitish, with a line of brownish black 
across the top. The last segments are paler than the rest, 
and the under side is paler than above. 
This butterfly is on the wing in Orono from the middle of 
June to the last of July.
