Uaanpa. — Behungi, on the Escarpment, at 8,300 ft., one female biting man, 
April 4, 1927. Between Chakansengula and Kasengui, March 1912 (L. Bayer). 
This species is known with certainty only from Uganda and the western part 
of Kenya Colony. Bezzi (1914, Ann. Mus. Zool. Univ. Napoli, N.8., IV, No. 14, 
p. 2) has recorded it from Northern Rhodesia (between Broken Hill and Bwana 
Mkubwa), but I doubt the correctness of this identification. 
Hippocentrum Austen 
Hippocentrum Austen, 1908, Ann. Mag. Nat. Hist., (8) II, p. 352. Type by original designation: 
Hippocentrum versicolor Austen, 1908. 
This genus is very closely allied to Haematopota, the only distinguishing 
characters being those given in the key to the genera. It also holds the wings 
in roof-like fashion when at rest. It is exclusively Ethiopian and restricted to the 
moist and warm rain forests of the West African Subregion. Four distinct species 
have been described. Two of them are found in the Belgian Congo and may be 
separated as indicated below. Both are shiny black, with the two basal seg- 
ments of the antennae partly, the tibiae mostly, and the tarsi partly, dirty yellow- 
ish to white. H. murphyi Austen, of Sierra Leone, differs from either in the much 
larger size (11.5 to 12 mm.), in the tibiae being black over more than their apical 
half, as well as in the almost uniformly infuscate wings. The fourth species, 
H. concisum Speiser, of Cameroon, is conspicuously distinct by the yellowish- 
brown abdomen. 
1. Wing fairly uniformly infuscated, slightly paler in the basal half, darkest about the black 
stigma, with three short hyaline streaks: one below the base of the stigma covering 
the base of the first submarginal and first posterior cells, one before the fork of the 
third longitudinal vein extending from the costa to the third longitudinal vein, and 
one in the apex of the wing from the tip of the second longitudinal vein to the hind 
mare. Meng. 8.5 to O MM. 25 cc Guns won ene ee kere a eee H. strigipenne. 
Basal anterior half of the wing (as far as the stigma, the base of first submarginal, first 
posterior and discal cells, and the fifth longitudinal vein) nearly hyaline; the extreme 
base, the costal cell, and the stigma, yellowish; the remainder of the wing uniformly 
infuscated, with a broad hyaline streak running before the fork of the third longi- 
tudinal vein from the costa to the lower angle of the discal cell. Length, 9 mm.
