1944 ] Some African Bees of the Genus Nomia 49 
Nomia elgonica sp. n. 
d\ Length nearly 10 mm., anterior wing nearly 9; black, 
rather slender, antennae black, hind tibiae chestnut red, front and 
middle tibiae reddened at end, tarsi pallid reddish; head circular 
seen from in front; face covered with slightly fulvescent hair, in 
one specimen partly denuded on clypeus; front and vertex dull; 
thorax with dull white hair, scanty above ; mesonotum dull ; scu- 
tellum hairy, dull, unarmed; area of metathorax a rather wide 
channel, broadly angulate in middle, with cross plicae; sides of 
metathorax posteriorly dull; tegulae rather elongated, posteriorly 
with a dark boss, but anteriorly broadly thin and hyaline; wings 
long, conspicuously reddened, but without a dark apex; stigma 
very pale red, nervures darker; basal nervure with lower section 
straight except at lower end, where it is abruptly bent and meets 
nervulus; second submarginal cell large, varying in width, re- 
ceiving recurrent nervure beyond the middle; hind femora mod- 
erately stout, with a strong tooth beneath; hind tibiae very broad 
apically; abdomen dull, without a red spot; fourth and fifth 
sternites shining, not tomentose. 
Uganda; Mt. Kojanjero, S. W. of Elgon, 6400 ft., Aug. 7-9, 
1911 (S. A. Neave). Two specimens. 
In a series of similar species it is known by the red hind tibiae, 
ordinary head, and entirely dull mesonotum, without punctures 
evident under a lens. It is to be compared with N. langi Ckll., 
which comes from Stanleyville in the Belgian Congo, and agrees 
in the toothed hind femora and red hind tibiae; the wing is 7.4 mm. 
long, and the mesonotum is different. There is evident affinity 
with the South African N. phenacopoda Ckll., which is smaller, 
and has a broad short head, and a red spot at end of abdomen. 
Compared with N. dominarum Ckll., the stigma is very much 
paler, and the marginal cell is shorter. N. snelli Ckll., from 
Zanzibar, is also related, but the hair on thorax above is quite 
different.
