 Hemimene banana Barnes and McDunnough, Check List Lepid. Bor. 

 Amer., no. 7267, 1917. 



Close to radicicolana and with similar genitalia, but darker, and 

 grayish rather than fawn colored. In some specimens there is a faint 

 indication of a pale shade on mid dorsum ; but in most it is not distin- 

 guishable. This dorsal pale marking is rather variable even in spe- 

 cies where it is normally present and sharply contrasted against the 

 ground color. 



Male genitalia figured from type. (The harpes are somewhat bent 

 on the slide which has caused a foreshortening of the cuculli in the 

 photograph. They are shaped very much like those oi radicicolana.) 

 1 have seen no females.
