Dipiera from South Africa. 105 



NemestrinidsB. 

 (llinnoneuridte, Loew.) 



Prosceca Westermanni, Wicdcm., Dipt. Exot. i. p. 155 (1821) ; 

 id., Auss. zweifl. Ins. i. p. 217 (1828) ; Schiuer, Reise 

 Novara, p. 113 (18GG). 

 Nemestrina Vesteniianni, Wiedem., /. c. 



Three males and one female from Barberton {Harrison, 

 Kendall) and Pretoria (/F. L. D.). 



? Prosceca, sp. 

 One male, antenuje wanting, from Barberton (Harrison) . 



Nemestkina sensu lato. 



Two female specimens from "near Enreka, Barberton '' 

 {Rendall), with two-jointed antennal bristle, which precludes 

 their inclusion in Prosceca, Schincr, and the shape of the 

 palpi, which are thick and apparently two-jointed, prevents 

 their being included in Rh y nchoccphulus , Fisher. 



Cyrtidae. 



Psilodera fasciatus, Wiedem., Zool. Mag. iii. p. 14 (1819) ; 

 id, Auss. zweitl. Ins. ii. p. 14 (1828) ; Loew, Dipt. Svid- 

 afrik. p. 257 (18G0). 



Cyrtux fiiscicttiis^ Wiedem., /. c. 

 Fsilodera ftiaciuta, Eiichson, Entomogr. p. 146. 



Psilodera capcnsi's, Gray, Griff. Anim. Kingd., Ins. xv. tab. 128. tig. 4 ; 

 Westwood, Trans. Eut. Soc. v. p. 92. 



One male from Barberton {Rendall). 



This agrees with Wiedemann's and Loew's descriptions, 

 but the third posterior cell is pedunculated; Loew expressly 

 states it is not, and that it is thus distinguished from cingu- 

 lata, Loew, and Ijijuaictala, Wiedem. 



A specimen laljcllcd fasciata in the British Museum Col- 

 lection is identical with the above specimen, but has the cell 

 pedunculated ; it seems probable that this is a character that 

 varies in this species. 



Syritta ?, sp. n. 



One male from Pretoria {JJ^. L. D.). 



Allied to S. flaviventris, Macq., Dipt. Exot. ii. (2) p. 75, 

 and Schincr, Reise Novara, p. 307, but apparently distinct 

 from it ; as Schiner states that Macquart's species possess no 

 tooth-like spines on the hind femora, and this specimen has 

 them.
