Proseca Westermanni, Wiedem., Dipt. Exot. i. p. 155 (1821) ; 
id., Auss. zweifl. Ins. i. p. 247 (1828) ; Schiner, Reise 
Novara, p. 113 (1866). 
Nemestrina Westermanni, Wiedem., 0. c. 
Three males and one female from Barberton (Harrison, 
Rendall) and Pretoria (W. L. D.). 
? Proseca, sp. 
One male, antenne wanting, from Barberton (Harrison). 
NEMEsSTRINA sensu lato. 
Two female specimens from “near Eureka, Barberton” 
(Rendall), with two-jointed antennal bristle, which precludes 
their inclusion in Proseca, Schiner, and the shape of the 
palpi, which are thick and apparently two-jointed, prevents 
their being included in Rhynchocephalus, Fisher, 
Cyrtide. 
Psilodera fasciatus, Wiedem., Zool. Mag. ii. p. 14 (1819) ; 
id. Auss. zweifl. Ins. ii. p. 14 (1828) ; Loew, Dipt. Siid- 
afrik. p. 257 (1860). 
Cyrtus fasciatus, Wiedem., l. ¢. 
Psilodera fasciata, Kvichson, Exitomogr. p. 146. 
Psilodera capensis, Gray, Griff. Anim. Kingd., Ins. xv. tab. 128, fig. 4; 
Westwood, Trans. Ent. Soe. 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 bipunctata, Wiedem. 
A specimen labelled 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, 
Syritia ?, sp. n. 
One male from Pretoria (W. L. D.). 
Allied to S. flaviventris, Macq., Dipt. Exot. ii. (2) p. 75, 
and Schiner, Reise Novara, p. 367, 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,
