rod-like, abruptly narrowed at basal third, beyond which 
they are thicker than in H. variegata and blunter at the 
pointed apex. 
6. Hippobosca hirsuta Austen. — I have seen the types 
of the typical form and the var. neavei Austen at the British 
Museum. 
Additional Specimens Examined. — Uganda: near Lake 
Albert (H. Hargreaves). — Nyasaland: Akamanga, Run- 
yinya River, N. Nyasa, off waterbuck (J. B. Davey). 
The preapical bristles of the scutellum are much weaker 
in this species than in most other members of the genus, and 
pale-colored. In the few specimens seen their total number 
varies from 14 to 18 (1 with 14, 1 with 15, 1 with 16, and 
1 with 18, for the males; 1 with 14 and 1 with 16, for the 
females) . 
The structure of the abdomen is similar to that of H. 
variegata in both sexes. 
The parameres of the male genitalia differ from those of 
all other species of the genus. They are broad and thick, 
beam-like, slightly wider basally and apically in side-view. 
The apex is straightly truncate, shallowly and evenly emar- 
ginate, so as to produce two blunt edges, one dorsal and one 
ventral. 
7. Hippobosca martinaglia Bedford, 1936, Onderste- 
poort Jh Vet. Sci. An. Ind., VII, pt. 1, p. 67, fig. (on p. 68) 
( 9 $ ; off Impalla, Aepyceros melampus (Lichtenstein) ; 
Bar R. Ranch, Swaziland, South Africa). 
In the absence of specimens, I have inserted this species in 
my key on the assumption that there are setas on the basal 
section of the third longitudinal vein and that only one of the 
pulvilli is well-developed, neither character being mentioned 
by the author. From the figure and description, it appears 
to be closest to H. hirsuta , likewise found on antelopes. It 
differs in the smaller size, the few short black setae of the 
mesonotum, the few preapical bristles of the scutellum, the 
wider frons, the narrower inner orbits or parafrontalia 
(less than half the width of the mediovertex or frontalia), 
and the short, semi-elliptical postvertex. The second longi- 
tudinal vein is described as “long”, but the figure shows it 
to be “short”, reaching the costa a short distance beyond the
