declivity it rapidly widens, until about where it descends in 

 front, it narrows and reaches the anterior edge in two broken 

 lines, at the point of widest expansion the sides are broken 

 and send a slight line internally ; the sides of the declivity 

 have a large broken tubercle between the base and apex, 

 laterally there appears a large prominent tubercle. There 

 are about three or four short elevated lines near the anterior 

 front, nearly attaining the margin, these lines resemble the 

 markings in C. scrofa Lac. : the elytra are truncate behind, 

 coarsely and transversely semi-confluently punctate, with 

 raised semi-circular line from the base around the scutel and 

 not attaining the suture, another beginning with quite a 

 prominent tubercle in the middle of the base and parallel to 

 the first, then with a sharp transverse ridge inwards and 

 another sweep ending in another ridge which nearly attains 

 the suture about its middle, a humeral line which is broken 

 after the middle. The rear is occupied by about six tuber- 

 cles, of which the most prominent are the two apical, one 

 costiform near the suture, the other dentate lateral, suture 

 dentate, the first segment of the abdomen has two lateral 

 tubercles, one sharp, covering the end of the femoral cavity, 

 the other large and flattened, surface coarsely reticulately 

 punctate, pygidium shining, sparsely punctate, median carina 

 fine, lateral in the form of a reversed S, with a faint median 

 connection, prosternum scarcely compressed, almost regu- 

 larly triangularly narrowed from front to rear.
