334 LEPIDOPTERA. 



of green, or else bright velvety yellowish- green ; the dorsal 

 vessel a rather deeper tint of the same, edged with fine lines 

 of pale greenish-yellow ; the subdorsal fine line is yellow, 

 and between it and the spiracles runs another such fine line 

 which passes through a broad black lateral stripe, dividing 

 it into two, in some specimens completely, in others only 

 partially ; spiracles white, delicately outlined with black, and 

 beneath them is a broad stripe of pale yellow or whitish- 

 yellow ; undersurface and legs paler green than the back. 

 In one individual a short tapering black streak issued at 

 the end of each segment for half its length forwards, as 

 an edge to the subdorsal line; but these streaks appeared 

 only on the fifth to twelfth segments. The black marks 

 on the head and second segment appear to be constant and 

 characteristic of this species ; they may therefore be more 

 minutely described as follows : A broad irregular blotch 

 down the front of each lobe, forked at the side, a round 

 spot on the face between them, and two pairs (sometimes 

 more) of black dots on the second segment. The pale lines 

 of the back are absent from the second segment and from 

 the anal flap ; the anterior legs are generally spotted with 

 black. 



A variety is of a dingy, rather olive-brown ; lines pale 

 pinkish-grey; with only the usual black marks on the head, 

 second segment and anterior legs. 



The young larva up to half an inch in length is very 

 dingy and nearly black, but bears some exceedingly fine 

 pale drab longitudinal lines ; after moulting and when about 

 three-quarters of an inch in length, it becomes less like the 

 larva of a Nodua in form than it was before, and more like 

 a Geometra, both in form and manner of progression. Its 

 colour is now a delicate green, inclining in some instances 

 to glaucous; the longitudinal lines and segmental folds 

 become whitish-yellow ; the head and second segment 

 spotted with black ; the growth now is rapid ; in some indi- 

 viduals black spots appear on the sides, in a day or two
