Diptera from South Africa. 93 
Exoprosora, Macq. 
The figures of the Exoprosopa species in Table II. of Loew’s 
Dipt. Siidafrik. are incorrectly given in the letterpress m 
many instances, and should stand thus :— 
& 
. maculosa, fig. 42. 
E. venosa, fig. 41. 
E. balioptera, fig. 40. 
E. rasa, fig. 39. 
E. angulata, fig. 37. 
E. umbrosa, fig. 36. 
E. corvina, fig. 39. 
E reticulata, fig. 34. 
I have followed the grouping of the species given by 
Loew, as forming a convenient classification. 
Division I. 
B. Wings obliquely bordered with black on the anterior half and 
the posterior half clear. 
Exoprosopa dimidiata, Macq., Dipt. Exot. Suppl. 1, p. 107, 
tab. ix. fig. 11 (1846); Loew, Dipt. Siidafrik. p. 225 
(1860). 
Four females from Pretoria (W. LZ. D.) and Barberton 
(Rendall). 
These agree with Loew’s description, with the exception 
that the colour of the first two joints of the antenne and of 
the legs is more reddish brown than black. 
Exoprosopa eluta, Loew, Dipt. Siidafrik. p. 227, tab. ii. fig. 25 
(1860). 
Eight males and three females from Pretoria (W. L. D.) 
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 discal cell from the angle of the 
cross-vein which divides it from the third posterior cell. 
The third joint of the antenne (wanting in Loew’s type) is 
the same colour as the others.
