G. GROUP PUNCTULATA. 



EXOPROSOPA (EXOPROSOPA) PUNCTULATA, Macquart (1840). 

 Dipt, Exot, II, p. 48, pi. xviii, fig-. 2. 



An eminently characteristic species, distinct from all its allies on 

 account of the spinulose front tibiae. 



Widely spread over the Ethiopian region. Dunbrody, Blue Cliff, 

 Uitenhage (Cape), March 1st, 1912 ; Cape Town (E. M. Lightfoot), 

 March, 1917; Klipfontein, Namaqualand (Cape), L. Pt'riuguey ; 

 M'Fongosi (Zululand), W. E. Jones. 



EXOPROSOPA (EXOPROSOPA) PERPULCHRA, Bezzi. 



Distinct from the other species of the group on account of its rich 

 wing pattern, consisting of 2 broad fuscous bands, crossing the wing 

 at the two ends of the discoidal cell. 



Orio-inallv described from Nvassaland, and not hitherto known from 



o * 



South Africa; there is a specimen from Salisbury, S. Rhodesia, 

 January, 1915 (J. O'Neil). 



EXOPROSOPA (EXOPROSOPA) PARVULA, Bez., uom. nov. 

 E. parva, Eicardo (1901), not parva, Loew (1869). 



Evidently allied to the preceding species, but distinguished by the 

 dark wing pattern, which is destitute of isolated spots, recalling that 

 of the dimicliata group. 



Originally described from the Transvaal, there is a specimen from 

 Kimberley (Cape) 1892 (L. Periuguey). 



A male specimen from Pretoria, Transvaal, November 10th, 1916 

 (G. A. H. Bedford), has the frous a little broader, the femora black, 

 and the wing pattern more infuscated. In the right wing of this 

 specimen the discoidal cell is exactly divided into two cells by a 

 supernumerary cross-vein, placed in the middle. 



EXOPROSOPA (EXOPROSOPA) STANNUSI, Bezzi (1912). 

 Easily distinguished by its well-defined dark fore border of wings, 

 the second basal cell being, however, almost entirely hyaline. Origin-
