are not quite so thick. The wings are rather darker and the 

 insect is smaller. 



Length 15 millim. 



Type (female), Zomba, British Central Africa (Rendall). 



Pangonia, Rond. 

 Pangonia biclausa, $ , Loew, Dipt. Sudafrik. p. 19 (1860). 



One male from Pretoria (W. L. D.). 



This agrees with the description of the female given by 

 Loew; it is one of the species with the fourth posterior cell 

 closed (see Ricardo, Ann. & Mag. Nat. Hist. (7) v. p. 109, 

 and remarks on P. brevis, Loew, which will also apply to this 

 species). 



Pangonia ckiysopila, Macq., Hist. Nat. Dipt. i. p. 194 (1834) ; 

 Walker, List Dipt. pt. v. Suppl. 1, p. 137 (1854). 



One female from Pretoria (Rendall). 



Probably belongs to this species. Macquart's description is 

 very meagre ; if correct, it belongs to Pangonia, Rondani, 

 the eyes being bare.

One female from Pretoria (W. L. D.); two males and two 

 females from Namaqualand (Cochrane) ; two males from 

 Barberton (Rindall) ; one female from Kowie, Jan. 1895 

 (F. Pym) ; one male from Pretoria (W. L. I).), Oct. 1895. 



The female from Kowie has the first posterior cell closed 

 and pedunculated, similar to a female in the British Museum 

 collection ; there is no doubt these belong to the above species, 

 which evidently must be added to those other species of Pan- 

 goninge which vary in this particular in different individuals. 



The males have the prolongations on the fore tarsi (see
