56 HYLOTOMA USTULATA. 



and the hinder pair before the apex on the upper side 

 whitish. The distinction in the coloration is, in my 

 opinion, of little value. All the whitish specimens I 

 have seen are referable tofuscipes, Konow. 



Thomson refers the Degeerian ustulata (nigripes, 

 Retz.) to enodis, but this must be regarded as an error. 



The larva, as described by De Geer, is clear green, 

 with a dark green, bordered on either side by white, 

 dorsal stripe. The skin is beset with warts, some of 

 which bear short hairs. The head pale brown, some- 

 what yellowish, and with a dark brown longitudinal 

 band. It fed in August on the common rose, entering 

 the earth at the end of that month, spinning a cocoon 

 of the usual kind. Curiously enough, no one has found 

 this larva since De Geer's time. 



Not common. Coombe and Darenth Woods (Ste- 

 phens). Andre says the larva feeds on Salix aurita. 



Continental distribution : Sweden, Russia, Germany, 

 France, Tyrol, Italy.
