As yet this species has been received only from the Uganda 

 Protectorate, whence the Museum possesses two females (the 

 co-types) from the Nile Province, June, 1906 {the late Dr. W. A. 

 Densliam). The collector's field-note is as follows : — " These 

 flies were noticed in great numbers in one camp only near the Nile, 

 and were very troublesome to my boys early one sunny morning ; 

 they clustered thickly on any small sore, and quickly filled themselves; 

 though preferring to feed in this way, they seemed also to insert the 

 proboscis into sound skin." 



The conspicuous abdominal markings seen in this species are an 

 unusual feature in Lyperosia, and will enable L. punctigera to be 

 distinguished without difficulty from any of its congeners hitherto 

 described.
