108 CEL^NA HAWOKTHII. 



soil on wild moorland ; and Mr. Batty kindly sent a 

 large tuft of the growing grass, which sufficed for 

 bringing the larvae to full growth. 



Of the four larva?, one was evidently diseased, as it 

 died on the evening after its arrival, but the remaining 

 three were lively and fed well ; and as one of them 

 seemed to be full-fed by the 25th of the month, I then 

 kept it apart from the rest, and saw it was beginning to 

 spin up on the same evening : on the 31st I made an 

 examination, and was glad to observe it in the pupa 

 state, reposing in a perpendicular position within a 

 slight cocoon composed of a few silken threads of 

 rather open work, holding around it some gnawings of 

 grass and a little " frass," and situated amid the 

 sheaths of the grass shoots. The perfect insect, a 

 male, came forth on the 1 5th of August ; but unfortu- 

 nately the tuft of grass grew mouldy, and thus the 

 other two never reached the imago state. 



The full-grown larva was three-quarters of an inch 

 in length, and of moderate stoutness, cylindrical in 

 character, except that the thickest segments were the 

 third and fourth, the body tapering from them to the 

 head, which was the smallest, and again behind most 

 gradually and slightly to the rounded anal tip, the 

 plate on which was flattened, and rather depressed 

 in the middle, having a slight marginal ridge behind. 



The colour of the head, of the plate next to it, as 

 well as of that on the hinder segment, was pale reddish- 

 brown, and highly polished, while the plate on the 

 second segment was margined in front with dark brown; 

 the mouth and ocelli dark brown ; the body of a 

 middle tint of purplish-brown above, and paler below 

 the spiracles, including the belly and legs ; the skin, 

 though smooth, quite without gloss ; a faint dorsal 

 paler line was visible chiefly at the end of each seg- 

 ment ; the subdorsal stripe a little more distinct and 

 paler ; the round tubercular warty spots were all very 

 dark brown and shining, each being furnished with an 

 excessively fine short brown hair ; the usual trapezoidal
