Hesperia dromus, Watson, P. ZS. 1893, p. 65. 
Hab. South Africa (? North of the Congo). 
This species is generally confounded in collections with the 
preceding, but by attending to the differences so clearly pointed 
out by Mr. Trimen they may easily be separated. Ploetz states 
that his type was from the Congo, and Mr. Trimen, upon the 
authority of G. Geynet, gives the ‘‘Gaboon River” as a habitat. 
I am inclined to question the correctness of the reference of this 
species to these localities. I may be in error, but am inclined to 
think that it does not range further north than Angola on the 
West Coast.
