"a. Orilla, West Canada. From Mr. Bush's collection." 

 It is impossible to apply this description. Mr. Grote, whose reference 

 of the species to Agrotis has been followed, gives no suggestion as to 

 the species it most resembles or where its allies are to be found.

Nothing answering sufficiently well to this description is known to 

 me. The pectinated antenuoe, however, narrow the possibility of associ- 

 ation somewhat.
