ExoPROsoPA, Macq. 



The fij;;ure.s of the Exoprosopa species in Tabic II. of Loew's 

 Dipt. Sudafrik. are iucorrcctly given iu the letterpress iu 

 many instances, and should stand thus : — 



E. maculosa, fig. 42. 

 E. venosa, fig. 41. 

 E. bdliojitcra, fig. 40. 

 E. rasii, fig. 39. 

 E. anguUita, fig. 37, 

 E. umhrosa, fig. 3(5. 

 E. corvina, fig. 33. 

 E reticulata, fig. 31. 



I have followed the grouping of the species given by 

 Loew, as forming a convenient classification. 



Divisiim I. 



B. \\'ings obliquely bordered with black on the anterior half and 

 the posterior half clear. 



Exoprosopa dimidiata, Alacq., Dipt. Exot. Suppl. 1, p. 107, 

 tab. ix. fig. 11 (1846); Locw, Dipt. Siidafrik. p. 225 

 (1860). 



Four females from Pretoria (//'. L. D.) and Barberton 

 {Rendall). 



These agree with Loew's description, with the exception 

 that the colour of the first two joints of the antenuHi and of 

 the logs is more reddish brown tiian black. 



Exoprosopa elutu, Loew, Di{)t. Siidafrik. p. 227, tab. ii. fig. 25 

 (I860). 



Eight males and three females from Pretoria [IT. L. I).) 

 and Warm Baths, Waterberg. 



In some of the specimens the shading of the wing is very 

 faint when it reaches the second basal cell ; in one specimen 

 there is an extra cross-vein on the basal half of the first 

 posterior cell in one wing only ; in another the stump of a 

 vein is emitted into the di.scal ceil from the angle of the 

 cross-vein which divides it from the third posterior cell. 

 The third joint of the antennje (wanting in Loew's type) is 

 the same colour as the others.
