Cremastobombycia. Braun. Trans. Amer. Ent. Soc. Vol. 34, p. 349 (1908). — Type : C. solidaginis, Frey. 



Characters. — Flead roughly tufted on crown, face smooth. Antenna; about 1. basal joint 

 rather thick, with slight pecten. Labial palpi moderate, porrected or drooping, filiform, pointed. Maxil- 

 lary palpi minute or rudimentary. Posterior tibiae with loosely appressed hairs. Forewings lanceolate;

 lanceolate, cilia 4; 3 absent, 4 absent, 5 and 6 stalked. 



Agreeing in general characters with Lithocollelis, particularly in the structure of the head, but with 

 neuration rather more primitive (an additional vein retained in both wings). 



Larva cylindrical, segment 2 broadest, thence tapering posteriori}', legs and prolegs developed; 

 mining blotches in leaves, with one surface contracted and wrinkled. 



Pupa in a cocoon within the mine. 



Foodplants (known for all six species) five Compositae, one Vevbtnaceae. 



Geographical distribution of species. — Confined to Xorth and Central America, but one 

 species has been introduced into the Hawaiian Islands.
