Head smooth, nearly inijiunctate, with the exception of the 

 impressed punctured space on either side bordering the inner 

 orbit of the eye, lower portion of face and the moi;th (the 

 apices of the jaws excepted) fulvous. Thorax twice as broad 

 at the base as long, basal margin bisinuate on either side, the 

 medial p(jrtion transversely truncate ; sides nearly straight, con- 

 verging from base to apex, hinder angles laterally produced, 

 very acute ; upper surface smooth, impunctate. kScutellum tri- 

 gonate, its apex obtuse. Elytra broader than the thorax, slightly 

 narrowed towards the apex, surface finely punctured, the ])unc- 

 tures becoming still iiner behind the middle ; the base to just 

 before the middle fulvous, the rest of the surface to the apex 

 black. Hinder thighs strongly thickened, ai)ex of last abdominal 

 segment imi)ressed with a small deep fovea ; metasternum 

 strongly impressed. This species is very nearly allied t<j M. 

 hicolor, it differs in having the whole of the head (the lower 

 part of the face excejited) and all the tarsi black ; it is also a 

 larger insect and the elytra are much more finely punctured. 

 I only know a single specimen, formerly in the collection of IMr.
