Black, but moderately shining, clypeus deeply emarginate, and 

 with the angles of the emargination a little reflexed and dentate 

 especiall}' in the male, transversely plicate, frontal carina high, 

 transverse, hardly arcuate and reaching the suture of the gente, 

 posterior part of head deeply punctate ; prothorax very convex, a 

 little retuse in front and with two lateral impressions in the anterior 

 part which are hardly distinct in the female, covered with very 

 closely set punctures which are a little shallower and slightly more 

 elongate in the median part of the disk ; the impression in the base 

 is very faint ; elytra very convex, deeply but finely striate and with 

 the intervals convex, sub-tectiform past the median part, and roughly 

 and irregularly punctate, pseudepipleura obsoletely rugose or nearly 

 smooth in some female examples, pseudepipleural stria distinct for 

 two-thirds of the length and varying a little in position, but set 

 nearer to the epipleuron than to the carina of the pseudepipleuron ; 

 under side punctured, the depth of the punctuation variable ; anterior 

 tibia? tri-dentate, and with a moderately distinct basal tooth above 

 the digitation. 



Length lOi- 11 mm. ; width 6-8 mm.

I have little doubt of the identity of M. pilula with my examples, 

 some of which come from the same locality as Dr. Sharp's female, 

 from which his description was made, but I am not so sure that 

 they are identical with M. poUtulus, Borre, the elaborate description 

 of which, however, corresponds exactly, except that Borre states that 

 the pseudepipleural stria does not reach quite to the median part ; 

 only in one of my examples does this stria reach the median part.

Shape, size, and colour of M. iioUtulus ; the head is similar ; the 

 prothorax is more convex, not at all retuse in front, and the lateral 

 impressions there are absent or indistinct, the punctuation is the 

 same, but a little finer, and the impressed line in the posterior part 

 is moderately distinct, the intervals of the elytra instead of being 

 convex and sub-tectiform are plane, but the striate part is sharply 

 costate, the stria3 are very fine and punctalate, and the intervals 

 between them are filled with finer and more shallow punctures than
