ber when they have reached their full size. According to 
Saunders, the caterpillar ‘‘at first eating a notch, about the 
size of its body, in the side of the leaf on which it is feeding, 
and placing itself in this notch, with the humps on its body 
somewhat resembling the irregularities in the margin of the 
partly eaten leaf, is not easily detected.” Yet notwith- 
standing this similarity to the edge of the leaf, expressed 
still more so by a similar caterpillar, that of the related 
Ianassa lignicolor, there are few worms that are as thor- 
oughly parasitized by Tachina-flies as these apparently so 
well hidden and protected ones. The mature caterpillars 
measure an inch and a quarter in length. They do not pos- 
sess the gregarious habits assome of those already described, 
being either found singly, or three or four together on the 
same twig. Towards September the caterpillar descends to 
the ground, and here it constructs under fallen leaves or 
other rubbish a thin and almost transparent papery cocoon 
and very much later it changes to a brown pupa, in which 
state the insect hibernates

with many darker brown wavy lines, two of which enclose 
a small whitish space. The hind-wings of the maleare dirty 
white, with a dusky spot on the inner hind angle; those of 
the female are sometimes entirely dusky. The body is 
brownish, with two narrow black bands across the front 
part of the thorax. The moth spreads nearly an inch anda 
half.
