RESTRICTION OF THE GENUS GELECHIA— BUSCK 573 



Two of the described American species of the genus, Lita puertella 

 (Busck) and Lita invanaUUs (Kearfott), have a peculiar, sharply 

 toothed, strongly sclerotized process on the front of the head pro- 

 truding beyond the scales (pi. 65, figs. 38, 39), undoubtedly corre- 

 sponding to a similar prominence on the pupa, which assists the latter 

 in cutting its way out through a tough surface, such as the stalk 

 of a dry desert plant. It is a specific character only, the other 

 species of the genus having normal flat or evenly rounded faces.
