 abdomen angulated, and its apex slightly notched; the anterior tarsi simple. 



Cape. 



There are several species of Megachile that are very similar to each other: I am acquainted with three 

 from India, three from Africa, and one from Australia; all these have a black head and thorax and a fulvous 

 abdomen. The present species most closely resembles M. bicolor; but from that species it differs in being 

 smaller, in the colour of the pubescence on the face, and also in that of the abdomen being more ferruginous; 

 the male of M. bicolor has the apical segment of the abdomen denticulate.
