220 CETONIIN^. 



The form is rather slender. The head is coriaceous, with its 

 front margin rounded and very gently curved upwards, and the 

 mentum horizontal. The pronotum is distinctly, but sparingly and 

 irregularly, punctured, rather narrow in front, with the lateral 

 margins strongly bisinuate and the basal margin nearly straight 

 but slightly augulated in the middle. The elytra are extremely 

 sparingly punctured, with the suture a little depressed in front 

 and elevated behind : the apical part is finely strigose and limited 

 in front by a sinuated carina. The py<iidium is shining and nearly 

 smooth, with a median longitudinal carina and a blunt tubercle on 

 each side. The sternal process is small, very feebly produced and 

 dilated, the sides of the metasternum are finely strigose and hairy, 

 and the abdomen is feebly rugose at the sides. 



The front tibiae are sharply bidentate in the female, but the 

 upper tooth is absent in the male, in which also the hind tibia is 

 sUghtly curved and drawn out into a single sharp spine. The 

 abdomen is deeply channelled in this sex.

 zontal. The pronotum is vei'y feebly punctured at the sides, narrow 

 in front and broad behind, with the sides nearly straight, the hind 

 angles almost acute and the base trisinuate. The elytra are almost 

 smooth, with a sharp jagged carina before the apex. The pyyidium 

 is finely strigose, with an impression at the apex, a sharp median 

 carina and a spinose elevation on each side. The sternal process is 

 very broad and flat, the sides of the metastermnn are finely strigose, 

 and the abdomen is almost smooth. The fifth ventral segment is 

 very broad, thinly punctured posteriorly and slightly deflected.
