Jegs black, with black pubescence, no fulvous pubescence on the 

 inside of the tarsi ; the pollen-brush black, with the middle pale

2 . Clypeus and front beneath the ocelli strongly and closely 

 punctured ; clypeus wedge-shaped, very slightly convex, its anterior 

 margin arched, a prominent fine vertical carina from the middle of its 

 base reaching nearly but not quite up to its anterior margin. Black, 

 the clypeus and the space below the anterior ocellus nearly bare, 

 remainder of the head and thorax and the basal segment of the 

 abdomen densely covered with rich fulvous pubescence ; the 

 antennae and legs pale fulvous ; 2nd and following segments of 

 the abdomen covered with short black pubescence above ; the 

 pollen-brush black ; in the majority of specimens the 2nd abdominal 

 segment is also thinly covered with fulvous pubescence ; wings 

 fulvo-hyaline, broadly fuscescent along their apical margins. 



(S similar, destitute of course of the pollen-brush, apex of anal 

 abdominal segment bidentate.

2 . Closely allied to and resembling M. dimidiata : differs in 

 having the clypeus more convex, shorter, posteriorly transverse, 

 anteriorly less arched ; the pubescence is a richer darker fulvous, 

 and on the abdomen is invariably dense and thick on the basal two 

 segments, the black pubescence on the remaining segments above 

 is also more dense ; the pollen-brush is fulvous along the middle, 

 with the margins broadly lolack; and the antennas and legs are black, 

 not fulvous red, the latter covered with a thin fulvous pubescence.

2 . Closely allied to and resembling M. Janata : differs in shape 

 of the clypeus, which is shorter, broader, more strongly convex, 

 and distinctly emarginate anteriorly, and in the abdomen being 

 more cvlindrical and very strongly convex above. Black ; the 

 front above the antennae, the thorax, and basal three abdominal 

 segments above covered with short dense fulvous-red pubescence ; 

 the clypeus, vertex of the head, the cheeks, and the legs with more 

 sparse and shorter pile of the same colour; the sides of abdominal 

 segments 4-6 and the 5th and 6th segments above also covered 

 with moderately long black pubescence ; pollen-brush thin and of
