African Phlehotoniic Diptera. 421 



Uganda : type and three other specimens received from 

 Colonel David Bruce, C.B., R.A.M.C., F.R.S., 1903; one 

 s])eeimen from Uganda, 1901, and another from Nimule, 

 Uganda, November 1901, '^ on cattle" {Captain E. D. W. 

 Greig, I.M.S). 



Although agreeing as regards its leg-markings with many- 

 other African species, Hcemutojwta fasca may be distinguished 

 from any of its African congeners at present known to me 

 by the uniformly sombre colour of the body, by the fact that 

 the light rosettes in the dark brown wings each consist of 

 but a single series of marks, and by the very conspicuous 

 upper portion of the light mark near the apex of the wing.
