In general appearance, Rhamphidia obsoleta agrees most 

 closely with R. cacoxena (Southern Nigeria), from which it 

 may be told by the darker thoracic pleura, the lack of 

 darkened wing-tips, the smaller and paler stigma, and the 

 different venation, the longer Rs, the longer Sc which ends 

 beyond the fork of Rs, the narrower and straighter cell R^ 

 which is suddenly dilated at its outer end, the lower cell 

 \st Mi and the consequent elongation of ?-ot, and other 

 characters. 



Rhamphidia morosa, sp. n. 



General coloration dark brown; rostrum about twice the 

 length of the head : wings uniforndy pale brown, the stigma
