streak pointing obliquely backwards, densely dark margined behind, its 

 dark margin continued into the densely dusted apex. Cilia; silvery gray- 

 ish with a basal dark brown hinder marginal line. Hind wings pale 

 silvery fuscous with silvery cilia-. Abdomen pale yellow ; tip silvery. Legs 

 white ; tarsi annulate with black. Al. ex. }( inch. 



The form and size of the mine in leaves of Q. obtusiloba, and the 



general reddish saffron hue of the insect, ally it to L. Bethuncella, L. uni- 



fasciella and L. casta nececlla, one of which I believed it to be until I bred 



it. In other respects it is allied as closely to the almella group, as above 



stated.

I am satisfied that in T. auristrigella I have re-described Dr. Clemens' 

 species, though I see no sufficient reason for separating it from Tinea. 

 T iridella Cham, will probably also be referred to Incurvaria.
