extremity extending along the upper border of the encarpsc 

 to the epistome ; antennae filiform, four or five lower joints 

 piceous, the rest black. Thorax considerably more than twice as 

 broad as long, the sides straight and parallel behind the middle, 

 thence rounded and converging to the apex ; above convex, sides 

 strongly deflexed in front ; surface coarsely but not very closely 

 punctured. Elytra very strongly and deeply punctured, punctures 

 arranged in longitudinal rows, which are indistinct on the basal half 

 of the disk, but distinct and regular on the hinder portion, where 

 the interspaces are strongly thickened and costate; on the anterior 

 two thirds of the outer disk the interspaces form irregular strongly 

 thickened reticulations. Thighs simple.

 tarsisque caeruleo-viridibus, supra viridi-^nea; antennis ni-

 angulum posticum subfoveolato ; elytris striatim punctatis, 

 punctis in striis bifariis confuse dispositis ; striis prope 

 apicem non approximantibus, regularibus, subsulcatis, inter-

Hab. Pulo-Penang, collected by Mr. Lamb. 

 Head distinctly but not closely punctured, front slightly con- 

 vex, impressed in the centre with a shallow longitudinal groove ; 

 epistome wedge-shaped, apical border obsolete, anterior border 

 produced into two very short obtuse teeth ; surface more closely 

 and coarsely punctured than the front ; labrum obscure fulvous ; 

 jaws and antennae black, the latter slightly thicker towards the 

 apex, the five lower joints obscure fulvous. Thorax rather more 

 than twice as broad as long, the sides straight and slightly con- 

 verging from the base to the middle, thence obliquely rounded 

 and converging to the apex, hinder angle tuberculate ; surface 

 distinctly and rather coarsely punctured, the puncturing much 

 coarser on the sides ; on either side of the hinder disk is a large 

 shallow fovea, which in some specimens is entirely obsolete. 

 Elytra slightly excavated below the basilar space, coarsely punc- 

 tured, the punctures irregularly arranged in double rows in front, 

 but forming single regular and slightly sulcate rows on the hinder
