PTER0PH0RUS FUSCUS. 363 



the dorsal stripe; the subdorsal lines are rather 

 indistinct, greyish- white ; below there is a still more 

 indistinct waved line of the same colour ; there is, 

 again, a similarly coloured faint line along the spira- 

 cular region ; and the segmental divisions also are of 

 this pale colour. In some specimens the hairs are 

 grey ; in others brown. The ventral surface is 

 uniformly of the same colour as the ground of the 

 dorsal area ; the legs are reticulated, and the prolegs 

 tipped with black. 



The pupa, which is attached by the tail only, is 

 rather long, but slender. The head, which is the 

 thickest part, is abruptly rounded, and has the snout 

 very prominent ; the thorax and abdomen are 

 rounded above, rather flattened beneath, and attenu- 

 ated strongly to the anal point ; the eye-, leg-, and 

 wing-cases are fairly prominent, the last prolonged a 

 considerable distance over the abdominal segments. 



As in the larva, there are two varieties of colour; in 

 one form the ground is bright green, and there is 

 little of any other colour, the pale grey abdominal 

 divisions, and two indistinct pale lines on the dorsal 

 area, with several faint purplish spots behind the 

 thorax and on the anal segment, being all that are 

 noticeable. 



The other form has the ground a dingier green, and 

 there is a distinct purple dorsal stripe, edged on each 

 side with greyish; the abdominal divisions and the tip 

 of the prolonged wing-cases are also purple. 



The pupa is capable of considerable movement, and, 

 on being disturbed, turns up sharply the thorax and 

 higher abdominal segments, so as to bring them quite 

 at right angles with the several posterior segments. 



The first imago emerged on the 29th of June, and 

 was quickly followed by a good series, which varied 

 in size very much, some specimens being quite small. 



Two species of parasites also emerged, one of them 

 an ichneumon with a long ovipositor, which Mr. 

 Bridgman informs me seems new to science. (George
