Specimens in coll. Br. Mus. (“Argentina, O. W. Thomas ”) 
and in coll. Bastelberger (Tucuman) have been determined 
as belonging to this species, and seem to agree well enough 
with it; but they may also be referable to the following. 
I am by no means clear that the two are not geographical 
races of one widely-distributed species. 
Warren described his types and other examples from 
Venezuela, Trinidad, Colombia and the Amazons. The 
species seems pretty generally distributed in Central 
America, Ecuador, Peru, the Guianas, etc., and the British 
Museum possesses one from Paraguay.
