 strongly punctured hinder disk of the elytra ; in form and in all 

 other characters it agrees with the former species.

Long. 2 lin. 



Hab. Borneo (Sarawak). 



Head moderately exserted, smooth ; epistome wedge-shaped, 

 not separated at its apex from the front, impressed on either side 

 towards the apex with a few deep piceous punctures, anterior 

 border broadly concave-emarginate; front impressed in the middle 

 with a shallow longitudinal groove ; encarpae separated from the 

 front by a piceous groove, which runs upwards on the upper 

 border of the eyes ; jaws black ; antennae slender, outer half pale 

 piceous. Thorax nearly twice as broad as long ; sides distinctly 

 angled behind the middle, thence obliquely converging towards 

 the apex, more quickly converging just before reaching the ante- 

 rior angle, the latter armed with an obtuse tooth, hinder angles 

 also toothed ; upper surface transversely convex ; anterior and 

 basal surface smooth, impunctate, middle portion impressed with 

 a large broad band of deep punctures, which extends entirely across 

 the thorax; just behind the anterior border is a sulcate groove, 

 the surface of which is impressed with a single row of punctures ; 

 lateral margin nigro-piceous. Scutellum subelongate-trigonate, 

 its apex obtuse. Elytra broader than the thorax, parallel, 

 excavated below the basilar space and within the humeral callus, 

 the latter thickened ; striae entire, rather strongly punctured and 

 subsulcate in front, the punctures piceous; behind the middle 

 the striae are not sulcate, more finely punctured, and the inter- 

 spaces plane ; the humeral patch extends from the shoulder nearly
