sparsely punctured or smooth ; the central tubercle is little or no steeper in front than 

 behind, and the size of its apical angle is variable ; from the central tubercle a median 

 keel extends forwards a short distance to the point of origin of the frontal ridges which, 

 with the straight, convex or slightly W-shaped ridge joining the frontal tubercles, 

 enclose a more or less semicircular area. Pronotnm with scarcely a trace of median 

 groove ; marginal groove incomplete in middle before and behind ; a patch of punc- 

 tures in anterior angles, scattered punctures present or absent between this and the 

 curved punctured scars. Prothoiax beneath punctured and hairy at the sides Scutel- 

 Itim smooth and polished ; mesothoracic episterna punctured above and along anterior 

 margin ; mesostenium with a few hair-bearing punctures in front of an anterior polished 

 area between the anterior ends of the scars, this smooth area usually continued 

 backw^ards as an indistinct keel, or as a smooth and highly polished streak, to about 

 the middle of a finely roughened area extending from the scars near their anterior 

 extremities to the posterior margin; between this area and the posterior part of the 

 scars the mesosternum is smooth and polished; the scars are long and almost always 

 coarsely punctured, the punctures sometimes extending beyond the scars themselves 

 into the lateral angles of the plate which they may completely fill. Metastenmm more 

 or less densely punctured throughout the lateral and anterior intermediate areas, and 

 often along the outer part of the posterior margin of the posterior intermediate areas 

 and the ridges separating these from the lateral areas ; anterior and inner part of 

 posterior intermediate areas rarely punctured ; the rest smooth and unpunctured ; 

 lateral areas much broader behind than in front, but not in contact with central 

 area. Hind coxae and abdominal sterna as in other members of the genus. Elytra 

 slightly hairy at the shoulders; all grooves of equal width; lateral grooves little more 

 coarsely punctured than those nearest the middle line.

Description.— Length 40-41-5 mm. Dift'ers from Trapezochilus nobilis in the fol- 

 lowing characters only. Anterior lower tooth of right mandible small and obtuse, but 

 distinct. Scars of mentum united to form a W-shaped figure, whose posterior trans- 

 verse part is always distinct and deeply impressed ; anterior margin of mentum some- 

 times with a slight concavity in the middle. Upper surface of head less strongly 

 rugose ; outer tubercles narrower, their denticles ver>' obtuse, middle denticle rarely 

 distinguishable. Only extreme lateral angles of scutellum unpunctured ; puncturing of 

 posterior angles of mesothoracic episterna also more extensive. Whole of lateral 

 margin of mesosternum bordered by a broad band of coarse punctures. Metastcrnum 

 with at least a few punctures in the posterior intermediate areas.
