ENNYCHIA OCTOMACULATA. 53 



broadly of a delicate light opaque cream-colour, 

 divided by a narrow dorsal stripe of rich and very 

 deep translucent green, narrowest at each end, and 

 sometimes there shows faintly within a still darker 

 pulsating vessel ; the pale cream-colour extends lower 

 down the side of the hinder half than on the front 

 half of each segment, and near the lower margin of 

 this colour is a fine line of translucent yellowish-green, 

 a little interrupted towards the end of some of the 

 middle segments ; the space between the light cream- 

 colour and the faintly showing tracheal thread is of 

 translucent green, broadest on the front half of a 

 segment ; below on the anterior segments is a stripe of 

 lighter semi-transparent green, which melts away into 

 the still lighter watery opalescent or greenish tint of 

 the belly and legs ; the tubercular slight warty 

 prominences have each a small central dot of trans- 

 parent green, bearing a fine whity-brown hair; the 

 third and fourth segments have sometimes a minute 

 black lateral dot ; the spiracles appear as most minute 

 brownish-black rings ; the whole surface of the skin is 

 glossy. 



When full-fed the larva turns almost of a uniform 

 yellow, though the back still retains its opacity be- 

 neath the glossy skin, and soon it spins for itself, 

 either between the leaves or in an angle of some 

 convenient surface, a whitish semi-opaque silken 

 outer cocoon of strong texture, from three-quarters 

 to an inch in length, and within it an inner series of 

 open- wrought threads, forming a kind of loose ham- 

 mock, in which it passes the winter unchanged. 



The cocoon which Mr. Jeffrey sent me to examine 

 is three-quarters of an inch long and of oval form, 

 ruptured to the extent of not quite an eighth of an 

 inch by the exit of the moth at the top of one end, 

 close to the leno to which it was spun above, and 

 spun below to a leaf ; the silk was whitish inside, but 

 externally had become of a dirty flesh-tint. The 

 pupa-skin, of ordinary figure, lying back uppermost,
