58 : August, 



body well out at the divisions, particularly on the belly where they 

 are very plump, on the back there is a deep sub-dividing wrinkle 

 across the middle of each segment, and an ordinary wrinkle on each 

 sub-division, the ventral legs slender, the anal pair stretched out 

 behind in a line with the body, and the head similarly extended in 

 front. 



In colour the head is whity-brown, having a few light brown 

 freckles and black ocelli, the back is 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 transparent 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 an uniform yellow, 

 though the back still retains its opacity beneath 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 

 hammock, 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 upper- 

 most, had the tail held fast by threads of the hammock which supported 

 it free from contact with the outer cocoon, the tail being very near 

 the end opposite to that from which the moth emerged ; the skin 

 itself was? exactly three-eighths of an inch long, moderately stout, with
