Head smooth. Tongue developed. Basal segment of antenna with 

 pecten. Labial palpus long, curved, smooth ; second segment slightly 

 thickened with appressed scales; terminal segment nearly as long as 

 second.

 posed and large. Cremaster absent. 



Remarks. — Endrosis may be distinguished from one group of 

 American oecophorid genera by tlie presence of pecten on the basal 

 segment of the antenna, and from those genera with peclcn by the 

 absence of vein 5 of the hind wing. In the larval and pupal stages
