250 NEPHOPTERYX ABIETELLA. 



The larva when stretched out is just half an inch 

 in length, rather slender in proportion, stoutest at the 

 thoracic segments, the others a little less but tolerably 

 uniform in width to the twelfth, whence it tapered a 

 little to the extremity of the thirteenth, which was 

 rounded ; the head is a little flattened, rather broad, 

 but not so broad as the second segment, which is 

 equal in length and breadth to the third and fourth, 

 the transverse wrinkles on these being rather deep, 

 while on the others, one moderately deep, followed by 

 a fainter one, subdivides each of them at about two- 

 thirds from the beginning ; the anterior legs are well 

 developed, the ventral and anal ones moderately and 

 much under the body. 



The head is shining and of a pitchy blackness, above 

 paler on the top of the lobes and brown beneath ; a 

 broad, black, shining, semicircular plate is on the 

 second segment, the skin of the body is without gloss, 

 and of a rich reddish- (rather chocolate-) brown colour 

 above on the back and sides, becoming a little paler on 

 the belly; on the sides at the segmental divisions the 

 skin appears paler, of a greyish glistening tint, seen 

 only when the larva is fully stretched out; the tuber- 

 cular dots are small, black, and shining, each emitting 

 a fine longish hair ; the spiracles are round, very 

 minute, of the ground colour, faintly outlined with 

 black ; a pale faint patch of ochreous is on the back 

 of the twelfth segment, and on the thirteenth it is 

 paler still, and has there a dark brown subdorsal 

 stripe, and the surface is shining. 



In the subdorsal regions of the third and the twelfth 

 segments is an ocellated spot of greyish or whitish- 

 grey, with black centre, bearing a hair. 



Another larva left its cone full-fed on the 22nd of 

 September. The length when stretched out was three- 

 quarters of an inch, its body one-eighth of an inch in 

 diameter. Its colour on the back and sides is rather 

 a bronzy-brown, the belly and the lower part of the 

 sides rather paler pinkish-brown; a very fine line or
