98 Miss G. Ricardo on 
segment; the underside is entirely red with light yellow 
pubescence, and black hairs at the apex. The wing differs 
from E. macroptera in the following particulars :—The base 
is almost entirely clear, only dark ‘at its root, the dark part 
divided from it distinctly by its straight transverse border, 
on its upper border where it meets the. clear part it does not 
form an S-shaped line, but a straight one across, not reaching 
beyond the base of the third posterior cell; the dividing 
vein between the first and second submarginal cells is formed 
with a sharp angle in its centre; the shading is brown and 
the veins brown. 
Length 13 millim. 
D. Wings with a black cross-band which does not reach the hind border, 
but” unites on the fore border with the extended dark shading of

fig. 31 (1860). . 
Ten females from Pretoria (W. L. D.); Barberton (W,

The stump of the vein emitted into the discal cell is very 
variable, in some of the specimens not being present at all, 
or only on one wing, and when present it varies in position. 
The proboscis, in one specimen at least, is as long as in 
the figure of Ezoprosopa (Litorhynchus) hamatus (Macq., 
Dipt. Exot. ii. p. 79, pl. xv. fig. 2), but is identical in all 
other respects with the others of the series: see Loew, J. c. 
pp. 223 & 232, on the length of the proboscis, which he does 
not consider a trustworthy specific character,
