 The third cubital cellule is shorter than the second, wider anteriorly 

 than behind through the third transverse cubital nerv r ure being some- 

 what obliquely curved. The second recurrent nervure is generally 

 received very near the second transverse cubital and may be joined to 

 it ; the blotch is large, white. The sixth joint of maxillary palpus is 

 one-fourth longer than the fifth, and they are shorter and thicker than 

 in fuscipes.

In this species the recurrent and the transverse
