MEGACHILE MELLIFERINA, Cockerell. 
Both sexes collected by Miss Robarts at Durban. The male, 
hitherto unknown, is about 10 mm. long, with the same general 
coloration as the female, the tegument of the abdomen largely red on 
basal segments. Antenne slender, black, not clubbed or expanded at 
end; face densely covered with cream-coloured hair; anterior tibiz 
and tarsi ferruginous, the tibie with long fulvous hair behind, the 
tarsi pallid, only moderately expanded, with long white hair behind, 
and an oval black spot on inner side at base of this fringe; anterior 
coxe with blunt and rather short spines; middle legs with extremely 
long white hairs behind; sixth abdominal segment strongly emarginate, 
but not dentate. This male resembles J/. unyulata, Smith in the 
coloration of the abdomen, but the legs are quite different. 
MEGACHILE VENUSTELLA, Sp. nov. 
@. Length about 11 mm., broad, black, with white and black 
hair; superficially like the European Jf. apicalis. Closely related to 
M. venusta, Smith (Kalahari specimen compared), but differing thus :
