194 Natal Bees 
S. africanus was described by Friese in 1908 from a single 
female from Ukami in Usambara. In 1911 Strand recorded a 
female from Delagoa Bay, and as it differed somewhat from Friese’s 
type, he called it var. delagow, Strand. The two forms were separated 
thus : . 
Tegule black or nearly so, with a yellow spot anteriorly ; thorax 
black ; antenne black. . . . africanus, Friese. 
Tegule pale yellowish anteriorly and brownish-yellow posteriorly, 
only the inner side posteriorly blackish ; lateral margins of 
mesothorax, prothorax and tubercles red ; scape and under- 
side of flagellum reddish . . . . delagoc, Strand. 
The Natal females have reddish tegule, with a pale area in front. 
The antenne are black. Only one, that marked ‘‘ Lower Umkomaas,” 
has the tubercles and upper part of prothorax bright ferruginous, and 
the lateral areas of metathorax suffusedly dark reddish. 
The male, not before known, is about 9 mm. long; wings fuliginous, 
but paler than in the female ; mandibles red, simple (with an inner 
tooth in female) ; face with long white hair, but lower half of the 
densely punctured clypeus bare ; first abdominal segment black, with 
the posterior margin very broadly red ; second red; third red, with 
a large black stain in middle ; remaining segments black, but apical 
plate red; legs black, the knees red and the anterior tibiz red in 
front. The antennz are black, the flagellum moniliform. This is 
considerably larger than the male of S. capensis, Cameron, and also 
differs by the darkened wings and greater amount of red on abdomen. 
The thorax shining between the punctures and the darkened wings 
separate it from S. punctatus, Sichel. 
The Natal specimens are not precisely typical africanus, nor are 
they typical delagoe. Possibly a third race is indicated ; but since 
the forms previously described are known from single specimens, and 
our material shows the insect to be variable, it is impossible at 
present to be sure that we are dealing with races rather than 
individual variations. Superficially, these insects resemble those 
species of Momia in which the abdomen is red.
