figured is the tuft of scales on the inner surface of the terminal joint of 

 the labial palpi — a character which I have never found in any of the 

 species which I have placed in Adrastcia. I am therefore not satisfied 

 that the two genera are exact equivalents. 



GELECHIA. 



G. scutettariaeetta. N. sp. 



This species approaches closely those which I have placed in Adras- 

 teia. There is a distinct divided bunch on the second joint of the palpi, 

 but it is smaller than in the species which I have placed in that genus, 

 and there are no tufts of raised scales. It differs from the true Gdechia 

 in having the last joint of the palpi but little mere than half as long as 

 the second joint, and the antennae but little more than half as long as 

 the wings. 



Blackish brown, tinged with blue, dusted with pale or bluish white, 

 with an indistinct whitish costal streak before the cilia, and an opposite 

 dorsal one. The white dusting of the primaries is more dense and more 

 hoary towards the apex of the primaries. Inner surface of the palpi 

 yellowish. Al. ex. y% inch. Posterior tibiae clothed with a tuft of long 

 hairs. 



This is a very plain and inconspicuous insect, principally remarkable 

 for the habits of the larva. It is white, with green contents, and head 

 pale straw color, and mines the leaves of the " Scullcap ;: (Scutellaria 

 lateriflora). It constructs a case or tube of silk lined externally with its 

 frass. The tube is nearly fiat, but curved, one side being convex and the 

 other concave, and it is wider at one end than at the other and attached 

 by its narrower end to the under surface of the leaves, and from it the 

 larva passes into the leaf to feed, retiring into the case when alarmed and 

 to pupate. It constructs but one case, and I think the attachment of that 

 one to the leaf is permanent, and that the larva makes but the one mine. 



I have never found it except in a single locality — near the village of 

 Verona, in Boone County, Kentucky. There it is very abundant in 

 September and October.
