528 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



mine, the hole occupying its entire breadth. If the species is distinct, 

 and this I am disposed to doubt, it may be called A. pruniella.

16. LithocolleHs cratcegella Clem. 



This insect is found on the apple and wild cherry (P. serotina), with- 

 out undergoing any variation which I can detect. 1 thought beyond 

 doubt that that in the leaf of wild cherry must be a distinct species, for 

 the larva has a habit unusual to larvte of this group, and which I have 

 not noticed in those on the thorn and apple, although, doubtless, they 

 correspond. The habit I refer to, in wild cherry miners, consists in de- 

 serting an old mine to form a new one — reminding one strongly of the 

 early habits of the Orniv larvje. The larva enters along the midrib to 

 form a new mine, which I have found in various stages of advance- 

 ment, besides the old aud tenantless mine in another portion of the 

 leaf. (Clemens.) 



17. Coleophora pruniella Clem. 



The larva mines the leaves of the wild cherry early in October, when 

 it is more than half grown. 



The case is flattened, having a notch on the upper edge about one- 

 third from the mouth, whence it is curved regularly to the hinder end, 

 and the under edge is nearly straight from the mouth to about one- 

 third of the length from the hinder end, where it is deeply notched and 

 curved towards the upper edge, thus forming a tail-like appendage. 

 On the upper edge, from the mouth of the case to the anterior notch, 

 the edge is regularly curved. (Clemens.) 



18. Tineid larva. 



The three following larvse were found at Berlin Falls, N. H., on the 

 wild cherry, September 13, 1887. The present species lives in a loose 

 white web in a folded leaf. 



iftj-yrt.— Body tapering towards each end ; the sutures rather deep. Head small, 

 amber-colored; body uniformly deep pea green, with four black piliferous warts on 

 each segment, from which arise pale hairs one-half as long as the body is thick. 

 Length, 9 to 10™"^ 



19. Tineid larva. 



This caterpillar lines a crumpled leaf with white silk. 



Larva. — Body tapering towards each end ; head small, much narrower than the 

 prothoracic segment, deep auiber-color, Prothoracic segment paler green than the 

 rest of the body, with an augnlar black spot ou each side ; rest of the body dark dull 

 bottle-green ; four large swollen dorsal tubercles arranged in a regular trapezoid, aud 

 three lateral warts, one of them bearing a large brown bristle, so that there is a lat- 

 eral row of large hairs on each side. TLoracic legs blackish ; abdominal legs bottle- 

 greenish. Length, 13'""'.
