Lives in a rolled-up leaf on Eupatorium ageratoides. This 

 larva, the first larva of the family Thyrididae to come to my notice, 

 shows that family to be correctly referred to the Tineoidea, near 

 the Pyralidse.

The three California!! specimens have been submitted to Lord 

 Walsingham in 1887, and to Prof. Fernald at a later date. The

CEnectra puritana Robinson. 



Larvae collected by Dyar and Caudell at Golden, Colorado. 



We sent a mass of leaves webbed by Tortricid larvae from 

 Colorado to Washington, D. C., where they were cared for by 

 Mr. Busck. The plant was PulsatiUa hirsutissima, and the
