Hab. Sarawak, Borneo. 



Head deeply constricted behind the eyes, the latter very pro- 

 minent, angularly notched ; face triangular, forehead depressed, 

 impressed in the middle with a single fovea ; antennae slender, 

 nearly equal to the body in length. Thorax distinctly broader 

 than long, sides very deeply constricted about their middle, upper 

 surface smooth, finely but subremotely punctured, deeply im- 

 pressed a short distance behind the lateral constriction by a 

 broad transverse sulcation, which extends at either side into the 

 constriction itself; disc gibbous, bounded on either side by a 

 deeply impressed and slightly sinuate longitudinal groove, which, 

 commencing at the base of the thorax, intersects the transverse 

 sulcation, and runs almost directly upwards and slightly out- 

 wards nearly to the apical margin ; the surface of gibbosity 

 finely but subremotely punctured, impressed longitudinally with 

 a fine grooved line ; tlie space bounded by the transverse groove 

 in front, posteriorly by the base of the thorax, and laterally 

 by the longitudinal sulci, is flattened and depressed. Scu- 

 tellum trigonate, its apex broadly truncate, extreme apex 

 black. Elytra much broader than the thorax, parallel, some- 

 what flattened along the back, closely covered with elevated 

 tubercles, the spaces between which are deeply impressed with 

 large round punctures ; each elytron in addition is furnished, with 

 seven much larger tubercles, greatly resembling those on the sur- 

 face of a Chlamys : they are placed as follows — the first on the 

 basal margin transverse, less curved than the others and obtuse; 

 the second just within the lower end of the humeral callus; the 

 third immediately below the basilar space, at some little distance 

 from the suture ; the fourth just below the middle, halfway be- 

 tween the suture and outer margin ; the fifth and sixth placed 

 obliquely nearly midway between the middle and apex, and the 

 seventh subapical, a little distance from the lateral border ; the last 

 six are all conical and strongly raised.
