G. Group punctulata. 



EsopROsopA (Exoprosopa) punctulata, Maecpiart (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. Dnnbrody, Blue Cliff, 

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

 March, 1917; Klipfontein, Namaqualand (Cape), L. Pcringuey ; 

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



Exoprosopa (Exoprosopa) perpulchra, Bezzi. 



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

 wing pattei-n, consisting of 2 bi'oad fuscous bands, crossing the wing 

 at the two ends of the discoidal cell. 



Originally described from Nyassaland, and not hitherto Icnown from 

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

 January, 1915 (J. O'Neil). 



Exoprosopa (Exoprosopa) parvula, Bez.. nom. nov. 

 E. parva, Ricardo (1901), not parva, Loew (18G9).

Originally described from the Transvaal, there is a specimen from 

 Kimberley (Cape) 1892 (L. Péringuey). 



A male specimen from Pretoria, Transvaal, November 10th, 191G 

 (G. A. H. Bedford), has the frons 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-
