THE CRANE-FLIES 1017 
Rostrum and palpi brownish black. Antennae with the scapal segments pale yellow above, 
dark brown beneath; basal flagellar segments yellow, short and crowded, with short verticils; 
outer flagellar segments dark brown, linear, with very long verticils, as in this sex in many species 
of the genus. Head above pale, the center of the vertex darkened. 
Mesonotal praescutum and scutum dark brown, paler laterally; scutellum dark brown, 
abruptly and conspicuously margined with whitish; postnotum dark. Pleura chiefly dark brown, 
with a broad whitish longitudinal stripe extending from and including the fore coxae, passing 
above the other coxae to the abdomen; dorsal pleurites somewhat paler brown than the sterno- 
pleurite and meron. Halteres pale, the knobs infuscated. Legs with the coxae pale, the middle 
and hind coxae narrowly darkened basally; femora brownish yellow, brighter basally, with a 
broad darker brown subterminal ring, the tips narrowly pale yellow; tibiae brownish yellow, the 
tips narrowly darkened; tarsi passing into dark brown. Wings with a grayish tinge, sparsely 
variegated with whitish subhyaline and darker brown; stigma brown, connected with a vague 
seam along the cord; narrower seams at origin of Rs; outer end of cell 7st Mz and on R;; prearcular 
region, cell C and conspicuous areas before and beyond the stigma whitish; ends of radial and 
medial cells not pale, as in sobrina; a vague transverse paling across the wing-disk just beyond 
the cord; veins pale brown, darker in the infuscated areas. Venation: Sc; ending shortly before 
the origin of Rs, Sc. not far from its tip; R; nearly perpendicular at origin, the cell relatively small; 
m-cu just before the fork of M. 
Abdominal segments dark brown, the caudal margins of the segments narrowly white. Male 
hypopygium with three distinct dististyles, the outermost a long, simple flattened blade; second 
style shorter, entirely blackened, curved into a crook at apex; inner style small, pale and fleshy, 
setiferous, terminating in two stouter setae. Gonapophyses appearing as flattened rods, the tips 
narrowed into glabrous blackened spines, divergent, their bases pale, clothed with abundant 
yellow setulae.

Gonomyia liberiensis is allied to G. (G.) noctabunda Alexander and G. (G.) 
sobrina Alexander, differing conspicuously from the former in the structure of 
the male hypopygium. Unfortunately, sobrina is still known only from the 
unique type female. It differs from the present species in the wing-pattern and 
details of coloration.

The genus Podoneura was proposed for the single species, P. anthracogramma 
Bergroth, from Cape Colony. Later, Riedel recorded the species from Kenya 
and Tanganyika (Kilimanjaro, at high altitudes, 2,400-3,000 meters). Still 
more recently I have recorded it from several additional stations in South Africa. 
A second species, P. brevifurcata Alexander, has recently been described from 
N’gwese, Lake Kivu, in the Belgian Congo. The discovery of the very distinct 
new species described herein as P. bequaertiana is of unusual interest. The three 
species of the genus now known may be separated by the following key: 
1. The fork of vein 2nd A very small, the longer or cephalic branch only a little greater than 
m-cu and without macrotrichia; m-cu less than its own length before the fork of M.
