i944] Some African Bees of the Genus Nomia 47 
N. ruwenzorica biconica Ckll., but easily distinguished by the 
tegulae and the peculiar pattern of the wings. 
Nomia heterura Cockerell 
Gold Coast; Yapi, Dec. 1916 (J. J. Simpson). A typical female, 
with red tegulae. The following females have dark tegulae, but 
seem to belong to the same species: Gold Coast; Yapi, Dec. 1916 
(J. J. Simpson), Yapi, Sept. 1916 (Simpson). S. Nigeria; Ibadan, 
July 27, 1920. N. Rhodesia; Buyamungoma Boma, Jan. 14, 1911 
(Silverlock) . 
Nomia platycephala Cockerell 
Pondoland; Port St. John, March, 1924, d (Turner). On 
close comparisons, I conclude that this is probably a form of 
N. matha (Cameron), although the wings are paler than is normal 
for N. matha. The legs are black, and it is certainly not the same 
species as N. breviceps Ckll., described from the male in 1939 as a 
sub-species of N. matha. The sexes of N. platycephala are tabu- 
lated in Annals Durban Museum, Aug. 1920. In Ann. Mag. Nat. 
Hist., March 1935. N. matha and the apparent synonym N. 
rugicollis Friese are discussed, and it is left uncertain whether we 
should recognize one or more races or closely allied species. 
Nomia laticincta Friese 
Lonely Mine, S. Rhodesia, six females, Dec. 1913, Jan., March 
and April 1914 (H. Swale). The tegulae vary in color, being in 
some specimens dark. As I suggested in 1939, this is probably to 
be regarded as a race of N . murinella Ckll. 
Nomia tricoloripes Cockerell 
British E. Africa: Masai Reserve, April 26, 1913 (T. J. Ander- 
son). $ . The female, not before known, resembles the male in 
most respects, but the legs are black, except the ends of the tarsi, 
and the front and middle knees. The hair on scutellum and post- 
scutellum is distinctly reddish, contrasting with the pale grey of 
the mesonotum. This suggests N. murinella , from which it is 
easily known by the dense fulvous abdominal bands, very broad 
on tergites 3 to 5. The tegulae are translucent pale reddish, and 
the short flagellum is dusky red beneath. The tegulae distinguish 
it from N. tricincta Friese, the tegulae of which have a black boss 
and a hyaline margin.
