creatures most wonderfully. They were, too, very 

 pugnacious, as two coming in contact immediately 

 showed fight, and bit each other with their mandibles 

 most unmercifully. 



They formed rather tough, white, glossy, silken 

 cocoons in the corners or on the bottom of the cage, 

 amongst leaves of the food-plant, and all changed to 

 pupae a day or two after finishing their cocoons. 



The pupa is large for the size of the moth; is 

 five-eighths of an inch long, glossy, and of the usual 

 shape, except that the case containing the head, eyes, 

 and palpi is considerably narrower and smaller than 

 the thorax ; and there is a very peculiar and conspicu- 

 ous tubercle on each side of the front of the thorax. 

 Colour, pale yellowish-brown, the eye-cases, dorsal 

 stripe, and abdominal divisions dark brown ; the 

 hooked anal point, and the eye-like frontal tubercles, 

 alluded to above, nearly black. 



Theimagos from these forced larvae appeared at the 

 end of September ; and at the same time the larvae of 

 the remainder of the brood, which had been kept at a 

 natural temperature, were fast spinning up. At 

 the beginning of October they had all become pupae, 

 in which state they will now no doubt remain over 

 until spring. (George T. Porritt, 3rd November, 

 1877; E.MJVL, December, 1877, XIV, 160.) 



E(JDOREA CEMBR^. 



On the 16th of May, 1882, I received in roots of 

 Tussilago farfara five or six larvae from Mr. J. Gardner, 

 of Hartlepool, which he supposed to be Eudorea 

 cembrae, from the fact of that species being seen to 

 fly in the neighbourhood of that plant. 



The larva is about 20 to 24 mm. when stretched 

 out at full length, and is of very slender proportion 

 in substance, rather tapering from the third segment 

 to the head and a little from the tenth to the thirteenth,
