NORTH AMERICAN EUCOSMINAE. 221 



Hind wing sordid white, margin narrowly shaded with pale smoky 

 fuscous ; cilia sordid white with a pale fuscous basal band. 



Male genitalia of type figured. 



Alar expanse. — 14 mm. 



Type. — In American Museum. 



Paratypes. — Cat. No. 21850, U.S.N.M.; also in collection Barnes. 



Type locality. — Aweme, Manitoba. 



Food plant. — Unknown. 



Described from male type and two male paratypes from Aweme, 

 Manitoba (Criddle, " 26-III-05 "), which Kearfott had included in 

 the series he determined as Exentera apriliana Grote. A true 

 Epinotia closest to vertumnana in genitalia, but otherwise most like 

 big^emina, from which it differs in its fuscous brown rather than 

 ferruginous brown color, its somewhat shorter palpi and the dark 

 band at the base of the cilia of the hind wings. It also differs 

 markedly from higeinina in genitalic structure.
