particular agrees with his description, which is not the case with 

 any species yet received from South America ; it is most probable 

 that the locality indicated is erroneous.

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

 the Museum Collection are examples from India and the Isle of 

 France : in all probability this is the insect described by M. 

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

 stacea. 



The abdomen entirely fulvous-red, the basal segment having 

 no black pubescence on its superior surface ; the pubescence of 

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

 of the antennae 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 line 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. 



TOO. MEGACHILE FRATERNA, n. s. B.M. 



Female. Length 7i lines. Black, the face as high as the 

 insertion of the antennae covered with black pubescence, leaving 

 the basal portion of the clypeus 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 within, but on the latter it is paler ; the wings 

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