110 Phyfophaga Malayana. 



Face coar5?e]y and deeply punctured, front impressed with a 

 fine longitudinal groove; anterior margin separated from tbe 

 encarpae and epistome, siruate on either side, middle produced 

 into a broad rounded lobe, lateral angles obtuse ; epistome dis- 

 tinctly broader than long, its apex broadly concave-emarginate, 

 sides slightly converging backwards, surface longitudinally con- 

 cave, deeply but not closely punctured ; encarpae broadly cul- 

 triform, upper half of the surface thickened ; antennae half the 

 length of the body, five upper joints broadly dilated, apical joints 

 obtuse. Thorax transverse, sides obliquely converging from base 

 to apex, slightly rounded in front, hinder angles acute; above 

 subconic, coarsely and somewhat closely punctured, rugose-punc- 

 tate on the sides. Elytra oblong, convex, deeply impressed below 

 the basilar space and within the humeral callus, the latter promi- 

 nent; surface coarsely punctured, the punctures irregularly ar- 

 ranged in double longitudinal rows ; interspaces on the hinder 

 disk thickened, several on the outer disk costate. 



Nearly allied to C. cuprcus ; narrower, more coarsely punctured, 

 epistome longer, thorax subconic, elytra more distinctly costate on 

 the outer disk.

Front separated from the epistome and encarpae by a deep

 a round obtuse lobe ; surface subremotely impressed with large 

 deep punctures, medial line longitudinally grooved, the groove 

 extending downwards from the vertex to the base of the anterior 

 lobe ; epistome triangular, its upper angle broadly truncate, an- j 

 terior border obsoletely angulate-emarginate; encarpae cultriform ;
