 transversim excavatis ; frontis margine antico obtuse angu-

 compressis ; elytris non tuberculatis, callo humerali ele-

Hab. Pulo-Penang ; sent in some abundance by Mr. Lamb. 

 Head closely punctured, lower margin of face separated from 

 the epistome and encarpae by a deep groove, obtusely angled, late- 

 ral angles distinct, medial produced ; epistome triangular, sides 

 slightly rounded ; surface closely rugose-punctate, shelving down 

 above until it reaches the level of the sutural groove, thus rendering 

 the latter indistinct in front ; encarpae cultriform, smooth, im- 

 punctate, impressed in the middle with a broad oblique groove ; 

 antennae nearly equal to the body in length in the $, robust, fili- 

 form ; rather more than half the length of the body in the $, six 

 outer joints compressed and moderately dilated. Thorax nearly 

 a third broader than long ; sides rounded, slightly converging in 

 front ; surface convex, closely and somewhat finely punctured. 

 Elytra much broader than the thorax j sides slightly but regularly 

 narrowed from the shoulders backwards, their apex subacutely 

 rounded, above convex, transversely excavated on each elytron 

 below the basilar space and also within the humeral callus, the
