BUTTERFLIES OF MAINE. 67 
The head is dark brown, very large, and with a small con- 
ical process on each side above. They make their first molt 
in about seven days, after which they are .16 of an inch long, 
with a yellowish head, finely mottled with red, and with a 
small, rounded, red process on each vertex. The body is 
drab, with either a green or a red tint, and striped lengthwise 
with dull red, one stripe along the middle of the back and 
two more on each side. The whole surface is covered with 
fine tubercles of irregular size and shape, each of which gives 
rise to a short hair. In six days they molt their skins the 
second time, and are then one-fourth of an inch long; head 
shaped as before, yellow, with two arched rows of rounded! 
brown patches across the upper part of the front. Body dulli 
ochery yellow striped with brown, one broad dark stripe along: 
the middle of the back anda similar one on the lower part of” 
each side; two narrow stripes on the middle of each side,, 
paler colored; tails reddish at the tips. 
The larva passes the third molt in fourteen days from. the: 
last, and is .44 of an inch long, the middle segments stouter,, 
the base broader than before ; color, pale ochre yellow, some-. 
what mottled with reddish on the back, but variable; the: 
lateral stripes sometimes nearly if not quite obsolete, and in, 
place of the upper one is a dark point or spot on the hinder: 
part of each segment from four to ten; basal ridge, buff;. 
surface more roughened than before; head nearly as before,. 
the spots on the face darker. 
These larve are at all times very sluggish, and frequently 
pass days without eating. It is probable that they hibernate. 
in this latitude after the third molt, and make the fourth and 
last in the spring, after their winter sleep. 
The mature larva is one inch long, flat on, the base, the 
back rounded, much arched on the middle segments, the sides 
flat and sloping, and there is a fleshy ridge aleng the sides 
over the feet; the second segment is much.constricted, and 
the last is forked. Color above, yellowish. brown, darker on 
the sides, a dark brown band running: along the back, and on,
