Short, thick ; facial ridge moderately raised and thickened ; 

 front smooth, not depressed, its lower part very obsoletely punc- 

 tured ; facial groove very deeply impressed, facial plates narrow, 

 almost linear; antcnnrc half the length of the body, moderately 

 robust, nearly filiform, being scarcely thickened towards their 

 apex. Thorax more than twice as broad as long, sides obliquely 

 converging and slightly rounded from base to apex, anterior 

 angles obliquely truncate, incrassatc; surface finely but not 

 very closely punctured ; base impressed on either side with a 

 deep, slightly curved, longitudinal groove; transverse groove 

 distinct, its middle sinuate and obtusely angled towards the 

 basal margin. Elytra broader than the thorax, ovate, their apex 

 rounded ; upper surface impressed just within the humeral 

 callus with an ill-defined curved groove, which bounds the lateral 

 margin together with the outer half of the hinder border of the 

 basilar space; striai deeply punctured, sulcatc on the outer

 plane, obsoletely convex towards the sides and apex.

 funde impresso, distiucte transversim sulcato ; elytris regulariter 

 punctato-striatis, striis fortiter iniprcssis, ad latera et apicem
