648 Prof. Mario Bezzi’s Report on a Collection of 
obliquely from the end of the second vein to the small cross-vein, 
dark brown. Isolated brown spot and shape of the cells as in 
E. batrachoides. 
TYPE f and four additional specimens from West Nyasa, 
Viyiya and Limpachi River, October and November 1909, 
all collected by Dr. H. S. Stannus, in whose honour the 
species has been named. 
67. Exoprosopa capnoptera, sp. nov. (Plate L, fig. 24.) 
?. Length of the body 18 mm., of the wing 17 mm. 
Very near the preceding and perhaps the female of it; but it 
seems to be distinct, being darker and having different wings. 
The hairs on the collar and on the sides of the thorax are golden, 
not grey. Halteres with blackish knob. Abdomen black, being 
only narrowly reddish on the sides; the hairs of the sides are all 
black, only the basal tuft of the first segment being, as usual, white. 
Spines of female genitalia dark yellow. Legs dark red, the coxae 
and the tibiae being in part blackened. Wings uniformly clouded 
with a clear brownish-black tint, the base and the costal cell being 
yellowish-brown ; cross-veins very lightly margined with fuscous. 
Wing-veins as in E. batrachoides, but the first posterior cell broadly 
open and the vein dividing the discal from the third posterior cell 
less sinuous. 
TYPE 9, from West Nyasa, hills, October 1909 (Dr. HS. 
Stannus); a single specimen. 
68. Hxoprosopa penthoplera, sp. nov. (Plate L, fig. 25.) 
3 2. Length of the body (of four specimens) 13-14 mm., of the 
wing 13-14 mm. 
In the venation this species agrees with those of the punctulata 
group, but differs in the shape of the abdomen, which is not conical. 
Head black, narrowly pale yellow along the mouth edges alone ; 
face rounded, not projecting ; hairs black. Antennae with the first 
joint black and black-haired, the second reddish, the third dark 
reddish, of elongate conical shape, bearing a short style. Thorax 
black, the hairs of the sides yellow, those on the pleurae also, with 
some black hairs intermingled ; metapleural tuft yellow ; squamulae 
dark, with a yellow fringe ; halteres with whitish knob. Scutellum 
black, with reddish margin and black marginal bristles. Abdomen 
entirely black, on the underside also ; it isnot well preserved, but it 
seems to be clothed with whitish tomentum and black hairs, the lateral 
tufts of the first segment being white. Legs black, the tibiae dark
