NEMATUS ISCHNOOERUS. 195 



greenish-white, head fuscous on the top, the base pale 

 and spotted with fuscous dots, mouth brownish. Over 

 the legs is a black stripe. The anal segment is marked 

 with two transverse black marks ; the first of which is 

 not half the breadth of the second, which is contracted 

 in the middle to near its base ; the cerci black, and 

 they are joined to the black transverse lines by a 

 black dot. 



The leaf is folded down on the lower side and usually 

 only on one side ; the fold is narrow, not being much 

 more than one line in breadth, and extends along the 

 greater part of the leaf. 



The imago appears in May and June, the larva in 

 July and August. It is not apparently a very com- 

 mon species. I have it from Clydesdale, Worcester 

 (Fletcher), Gloucester.
