76 BULLETIN 132, UNITED STATES NATIONAL MUSEUM 



Known only from the male type. Kearfott described from two 

 specimens, but I am unable to locate the one that is supposed to be in 

 the National Museum, The type is in very poor condition, much 

 rubbed, mouldy, and lacking a head. It looks like a runted specimen 

 of insiticicma. The genitalia are similar except for size, being con- 

 siderably smaller. The name had better be kept until other speci- 

 mens can be obtained, 



Male genitalia figured from type. 



Alar expaTise. — 14 mm. 



Type. — In American Museum. 



Type locality. — Plummer Island, Md. 



Subfamily Olethreutinae
