Elytra ovate, as wide as the base of the thorax, sides 

 rounded and diverging at the extreme base, then obliquely 

 diverging to beyond the middle, thence regularly rounded 

 to the apex. Above convex, the convexity increasing 

 from the base to beyond the middle ; surface more closely 

 punctured than the thorax, the puncturing arranged in 

 irregular striee ; on the disk are seen the faint indications 

 of two or three longitudinal vittte. Terminal joints of 

 maxillary palpi ovate, not broader than the penultimate. 



This insect is closely allied to Ch. Mahesa, ^L-impressa 

 and Fortunei. It differs from all in the absence of the 

 transverse sulcation below the basilar space of the elytra.
