A close ally of If. ambiguus, Per., but the male differs by the 

 plainly punctulate thorax, which is only very faintly aciculate in 

 M. ambiguus, the two basal joints of the anterior tarsi are more 

 broadly dilated in M. ambiguus, the female of which is not 

 known.

Female : Black, and more shiny than the male, shorter and much 

 more strongly declivous behind ; the prothorax is only one-third 

 broader than long, and as equally finely punctured as in the male, 

 the two dorsal costules on the elytra are as much obliterated as in 

 the male, the whole dorsal part as well as the declivous part is 

 smooth, but along the lateral costa there is a somewhat narrow band 

 of very plain granules beginning at a short distance from the 

 humeral part and reaching to the very apex ; legs and under side as 

 usual.

Very dark blue, almost black on the upper side, shining, glabrous ; 

 head deeply punctured, the punctures more closely set in the 

 anterior than in the posterior part ; prothorax rounded laterally, but 

 somewhat wider across the base than across the anterior part, 

 plainly convex on the disk which bears in the anterior part, but at a 

 short distance from the middle, two small, round impressions, very 

 sparingly punctulate on the sides and almost impunctate in the 

 centre in the male, but in the female the round punctures are deeper, 

 more closely set, and spread over the whole surface, the outer 

 margin is slightly and irregularly wavy, and the emargination above 

 the basal angle is shallow, but plain ; scutellum small, convex, 

 nearly impunctate ; elytra with the shoulders very sloping in the
