635. Hypostena barbata Coq. 

 Hood River, VI-16 (Cole) and VII-1 (Childs). Aldrich 

 says in regard to material sent for determination: "They 

 agree with what I call this, but Hypostena and Masicera run 

 together, and this is not separable generically from some I 

 put under the latter farther on. The supposed difference is 

 that in Masicera the first posterior cell ends considerably 

 before the apex of the wing, and in Hypostena close to the 

 apex. The distinction breaks down completely in your ma- 

 terial."
