evident from his comments on the fore tarsal teeth. The number of tubercles on the 

 fore femur of females in braueri is dependant on the size of the individual. Small 

 females have fewer tubercles and paucidens is here regarded as a small form. The 

 species is known from Sierra Leone, Ghana, Nigeria, Cameroon and Congo.

The unique holotype of intermedins is not in the British Museum (Natural History),

 Guinea. Moulton has indicated that this species varies in size and degree of develop- 

 ment of certain characters.
