AOIDALIA DEGENERARIA. 129 
I could not help noticing how closely, both in form 
and general appearance, these larvee of A. degeneraria 
came to those of A. mornata. 
When full-grown the larva of A. degeneraria 18 
seven-eighths of an inch in length, broadest at the 
ninth segment, and from thence tapering gradually to 
the head (the smallest segment); the posterior seg- 
ments taper but little to the rounded anal tip; the 
body is convex both above and below, and _ has a pro- 
jecting rounded ridge along the sides, so that it 
appears somewhat flattened ; the segmental divisions 
are well defined by the end of each segment project- 
ing at the side, in breadth, beyond the beginning of 
the next; the skin is rugose, with about twelve sub- 
dividing wrinkles in each segment; the head indented 
on the crown. 
In colour the head is chiefly blackish-brown, con- 
spicuously marked on the crown of each lobe with 
pale cinnamon or bright rust-colour, which extends 
as a stripe down its outer side; a patch of the same 
colour is on the dorsal surface of the three following 
seoments, being rounded at the sides on the second 
segment, triangular and poimting backwards on the 
third and fourth; with these exceptions, the rest of 
the back, as far as the end of the eighth segment, is 
deeply suffused with dark brown, the remainder being 
again of bright rust-colour, strongly contrasting with 
the darker hue of the middle segments; on the back 
of each segment, from the fifth to the ninth inclusive, 
are double darker brown markings, somewhat like Vs 
pointing backwards, and standing one a little in front 
of the other at the hinder part of the seyment; their 
limbs are curved outward soon after their commence- 
ment, and by degrees finely attenuated as they reach 
the next segment in front, each arm of a V being thus 
like a miniature willow leaf; in front of these, and 
embraced by their arms, is rather an elliptic shape of 
similar dark brown, and then a black square mark, 
close to the segmental division ; both of these shapes
