centre than on the sides ; scutellum narrow, hardly punctulate ; 

 elytra cylindrical but slightly emarginate laterally below the shoulder, 

 deeply punctato-striate, the eighth and ninth striae being of equal 

 length and ending at some distance from the base, while only the 

 sutural and outer striae unite at the apex, and the second and eighth 

 unite above the two above-mentioned ones ; anterior tibiae quadri- 

 dentate outwardly, but w^ith the basal tooth very small ; pectus 

 smooth in the centre, punctate laterally ; abdomen very deeply and 

 closely pitted and also briefly, yet densely, pubescent ; pygidium 

 smooth in the horizontal part which is compressed laterally and 

 is very prominent, and with a row of setigerous punctures round the 

 edge in the male ; in the female the pygidium is punctulate, slightly 

 carinate longitudinally in the middle, and being much less swollen 

 is more horizontal with the line of the abdomen, which is also not 

 transversely depressed ; legs smooth and reddish brown.

 disposed as in C. imncticollis ; metasternum smooth but granulate 

 laterally like the mesosternum ; abdomen hardly pubescent and
