NEPHOPTERYX ABIETELLA. 253 



of an inch long, of rather stout figure, uniform in 

 size, except that it tapered slightly from the third 

 segment forward to the head the smallest, the thir- 

 teenth segment very slightly tapering. 



In colour the head is black-brown, the plate on the 

 second segment also with wide dorsal division of the 

 same colour as the back of the larva, a rather reddish- 

 brown ; beneath the spiracles this colour is abruptly 

 separated from the rather paler colour of the belly, 

 most defined posteriorly ; the dorsal line is rather 

 darker brown, but on the thirteenth segment becomes 

 obliterated by a broad pale stripe, relieved by a dark 

 blackish-brown stripe on either side ; on the back the 

 tubercular dots are black, reddish-brown on the 

 belly; an ocellated spot of whitish, with black centre, 

 on the side of the third and the twelfth segments, 

 with extra long hair and a fine brown hair from each 

 dot. 



This iarva was observed out of the cone on the 

 14th of September, when I figured it; it was after- 

 wards placed with the cone in a jam pot containing 

 small fragments of rotten wood, and the moth emerged 

 on the 14th of June, 1878. 



On looking afterwards for the empty cocoon I 

 found it at just the distance of one-fourth from the 

 bottom, just inside the scales, at a part where they 

 had been much ravaged or broken away ; it was oval 

 in form, five-eighths of an inch long, composed of 

 whitish silk, but all (except the part attached to the 

 cone) was entirely covered with brown frass. 



The pupa skin (damaged by extraction) seemed 

 to have been about from a quarter to three-eighths 

 of an inch in length, and of light reddish-brown 

 shining colour. 



On the 8th of October, 1879, I received an infested 

 cone of spruce fir from Dr. Wood, drawing my atten- 

 tion to a singular feature in the economy of this 

 species. Pinned to the cone I found a round flattish 

 cocoon of white silk, partly covered with frass, con-
