Mipa stream, Mofwi, August 3, 1892. 



^ I haye placed this species at the end of the Hesperiidae because it does not 

 appear to me quite to agree with any of the genera indicated in Lieut. Watson's 

 Revision of the family ; from Afromachus, which it most nearly approaches, it 

 differs in the longer terminal joint of the palpi. 



P.S. — I find that by some inexplicable oversight the slip of lihopalocampta 

 f'orestan. Cram, (which was represented in both collections), has dropped out 

 of the MS.
