COSMOPTERYGID.«. 



I have now broken up the family Elachistidoi as formerly constituted, and 

 the family Cosmopterygidce includes those genera with long sickle-shaped palpi 

 and veins 7 and 8 of the fore wings stalked, 7 terminating in costa, such as 

 Cosmopteryx, Stagmatopliora, and Limnmcia ; in my last paper I termed this 

 restricted group Elachistidce, but now find that Elachisfa is referable elsewhere.
