Tyfe locality. — Dominican Republic, Sanchez.

Trinidad: Cedros (Darlington, in M.C.Z. ), St. Augustine (Darlington, In 

 M.C.Z. ), Four Roads (Thaxter, in M.C.Z. and U.S.N.M.). 



Specimens ea'aimncd. — I have seen one example from the Museum 

 of Comparative Zoology in addition to the types.

 the structure of the maxillary palpus. 



Ten of the paratypes were taken in "ditches in Brown's cacao."
