THE ENTOMOLOGIST. 45 



greenish yellow, with a quadrate shining black spot on the 

 vertex, and two large round similar spots on the sides, in 

 which the eyes were placed ; the trophi were somewhat 

 brownish : the head, both above and below, was shortly and 

 sparsely hirsute. In the younger larvae the body was sordid 

 yellow, with three brown-green stripes, the outer of which 

 were darker than the inner one ; the spiracles were pale 

 yellow ; above them were some black lines, and below them, 

 just above the legs, was a dark transverse line. Above the 

 anus was a small black spot. The three dorsal lines had the 

 appearance of being ribbed, the inner side of the numerous 

 folds of the skin being of a paler tint. The thoracic legs 

 were of a pale yellow, with black lines on the first or thickest 

 joint, the terminal claws being pale brown. The ventral 

 surface, as also the posterior legs, were pale, without spots, 

 the caudal end being beset with short white hairs. Those of 

 the size of fig. 2 were of a yellowish colour on the ventral 

 surface, purplish gray on the dorsum, with longitudinal 

 stripes. 



The little creatures remained quiet during the day, chiefly 

 reposing on the under sides of the leaves ; in the evening 

 they seemed more inclined to move about and feed, and ate 

 large holes in the leaves, but did not in all cases begin at the 

 margin, very often eating holes out of the middle of the 

 leaves, so that it might, at first sight, have been thought that 

 the elder-bush was infested by snails. 



In a short time all the larvge attained the size and acquired 

 the colour as shown in fig. 4. 1 also noticed that on each 

 thoracic leg were two dark gray triangular spots ; also that 

 the black spots above the spiracles had increased in size, 

 and that the edges of the stigmata were very pale brown. 

 Above each proleg were two oblique blackish spots, and a 

 triangular black spot above the anus. 



On the 6th of June and the following days they moulted 

 for the last time, when they assumed the appearance repre- 

 sented at fig. 8. The head was reddish, and the body wholly 

 of a very pale greenish gray colour, the three dorsal lines 

 being a shade darker than the ground tint. The black 

 points on the sides had entirely disappeared. 



About eight days afterwards they crept into the earth, 

 placed in the vessel in which they were kept.
