Obs. This species very closely resembles the M. mystacea ; in 

 the Museum Collection are examides from India and the Isle of 

 France : in all ])robability this is the insect described by M. 

 Guerin : the following ftifferences distinguish it from M. my- 

 stacea. 



The abdomen entirely fulvous-red, the basal segment having 

 no black pubescence on its su])erior surface ; the pubescence of 

 the head is entirely black ; the face a little before the insertiou 

 of the antennffi is obliquely truncated and roughened by irregular 

 sculpture ; the anterior margin of the clypeus is transverse, and 

 on each side is slightly produced before reaching the base of the 

 mandibles ; the mandibles are rounded exteriorly and have no 

 grooves towards the base, but have two short ones at their apex ; 

 the spines at the apex of the posterior tibiae red. 



Male.— In colour agreeing with the female ; the clypeus is 

 convex in this sex and has a thick fringe of white pubescence on 

 its anterior margin, a tuft of the same colour between the an- 

 tennae, and a hne on each side along the margin of the eyes ; 

 between these it is black ; the calcaria as in the female are red. 

 Hab. India ; Isle of France. 



100. Megachile fraterna, n. s. B.M. 



Female. Length 72 lines. — Black, the face as high as the 

 insertion of the antennae covered with black pubescence, leaving 

 the basal portion of the ch-jieus naked ; mandibles broad at their 

 apex and armed with three teeth. The pubescence on the thorax 

 and legs black ; on the posterior tarsi it is fulvous, as also on the 

 femora and tibiae ^\ itliin, but on the latter it is paler ; the wings 

 subhyaline, their apical margins having a fuscous cloud. Abdo-
