projects inward, forming an acute angle at the middle of the wing. 

 Hind wings pale fuscous with golden tinged cilia. Veins 7 and 8 of 

 the fore wings are separate. 



Legs silvery white, outwardly fuscous and with the tips of the 

 tarsal joints dark brown. 



Expanse : 9 mm. 



One specimen, Cincinnati, Ohio, May 28, 1910, captured in 

 a clump of willow trees, on the trunk of one of which it was 

 resting. I have kept this specimen for a number of years, 

 hoping to discover its food plant, or at least collect additional 

 specimens,. but without success. 



The species is most closely related to A. inscriptella Busck, 

 which has, however, a darker costal edge, and a greater por- 

 tion of the apical half of the wing dark.

Contrary to the usual habits of the larvae in this genus, 

 which, according to Meyrick (Handbook of British Lepidop- 

 tera) mine blotches in leaves, the larvae of A. incertella Cham, 

 feed within folded leaves. In May, at the time the new 

 shoots are developing, the young leaves toward the ends of 

 the shoots of Smilax hispida Muhl. are folded edge to edge 

 with the upper surface inside and are closely spun together 

 along the margins. The larva feeds within leaving the lower 

 epidermis of the leaf intact. At the time of pupation, the 

 larva deserts the leaf and spins upon a leaf or twiner, an open 

 network cocoon of yellowish or brownish silk, within which 

 the chrysalis is placed upright with anal end attached.
