﻿156 Annals of the South African Museum. 



Originally descril)ed by me from N.W. KhoJesia in my paper on 

 the Bombyliidae of the British Mii«eiim, there is a specimen from 

 Salisbury, Arcturus, I'JlG (Dr. Melle). 



ExopRosoPA (Exopkosopa) eluta, Loew (18()0). 

 Dipteren-Fauna Siid-Afrikas, p. 227, pi. ii, tig. 5. 



Very closely allied to the following one, but distinguished by the 

 smaller size, by the black legs and liy the faint infuscation on the 

 cross-vein dividing the discoidal from the second basal cell. 



Stellenbosch (Ca]3e), 1888 (L. Pcringuey) ; Ceres (Cape), Matroos- 

 berg, 5000 ft., January, 1917 (K. M. Lightfoot) ; another example 

 9 mm. in length from Zululand, M'Fongosi, December, 1914 (W. E. 

 Jones). 



ExoPROSOPA (Exoprosopa) hekos, Wiedemann (1819). 



A species of great or medium size, distinguished by the broad 

 fuscous patch of the hind half of the wings, 



I think that the form described by Loew (Dipt. Sudafrik. p. 3o4, 

 pi. ii, fig. oo) answers to the variety mentioned by Wiedemann, and 

 I have named it loewiana ; I think, moreover, that E. caffra, Macquart 

 {nee Wiedemann) is also the present species, which seems to be very 

 common in South Africa. 



There are numerous specimens, varying in length from 10 to 20 mm. 

 Stellenbosch (Cape), 1887 (L. Péringuey) ; Berg Kiver ; Laiugsburg, 

 November, 1910 (R. M. Lightfoot) ; Hex River, January, 1885, named 

 " heros " by Bigot; OOkiep (Cape), 1885 (L. Pcringuey) ; Barbertou, 

 Transvaal, November, 1911 (H. Edwards) ; Spektakel and Springbok, 

 Namaqualand (Cape), November, 1890 (R. M. Lightfoot) ; M'Fongosi, 

 Zululand, December, 1911 (W. E. Jones); Otjivarango, Damaralaud, 

 January, 1920 (R. W. E. Tucker). 



ExoPKOSOPA (Exoprosopa) dux, Wiedemann (1828). 



Probably only a variety of the preceding, distinguished by the want 

 of the fuscous patch at the hind half of the wing. 



Some specimens from Hex River (Cape), December, 1884 (L. 

 Pcringuey), and Bushmanlaud, Henkries (Cape), October, 1911 (R. M. 

 Lightfoot).
