Pangonia pyrausta, O. Sack, antea, p. 43 * ; Willist. Kans. Univ. Quart, iii. p. 189 \ 



To the localities given, add : — Mexico 2 , Navarete in Tepic (Schumann), Mazatlan 

 (coll. Williston 2 ). 



Four specimens, which I refer to this species, notwithstanding the fact that they all 

 have the first posterior cell closed. The characters otherwise agree well. The abdomen 

 is abraded, so that I can offer no opinion as to the differences between this species and 

 P. rhinophora, Bell., which must be very closely allied. 



2. Pangonia rostrifera.
