tlie striae broad and deep, containing large punctures which 

 liardly diminish posteriorly, the intervals rather narrow, 

 almost plane and impunctate ; intervals 2, 3, 7, and 9 are 

 united j)ostcriorly, where they form a l)road, obtusely elevated, 

 obliquo costa, which gives the elvtra their characteristic 

 oblong shape; when viewed obliquely from behind this costa 

 has the aj)pearaiice of an obtuse prominence. Le^s compara- 

 tively finely punctured.

Described from a single example. The species mov be 

 readily distinguished from any previously described Eastern 

 Cossonus by the curious posterior elevations on the elytra. 

 In other respects it is closely allied to C.foveicollis, Fst. 



The whole of the sternum (except the middle of the meta- 

 sfernum) and the sides of the first two ventral segments are 

 closely covered witli very coarse punctures, the rest of the 

 venter being ghibrous except for some scattered punctures in 

 the middle of the first and last segments and a single trans- 

 verse row on the third and fourth. .

Depth of body nearly equal to length of head, 3|-3| in 

 the length of the fish. "Snout shorter than diameter of eye, 

 which is 3 in the length of head and greater than the inter- 

 orbital width. Nostrils well separated. Maxillary barely 

 reaching the vertical from anterior margin of eye ; teeth 

 tricuspid, 32 scales in a longitudinal series, 12 in a trans- 

 verse series from dorsal to pelvic fins, 6 or 7 in the lateral 

 line, whicli does not extend to below the dorsal fin. Dorsal 

 13-15 ; origin equidistant from end of snout and base of 

 caudal, or a little nearer the former ; longest rays |-^ the 

 length of head. Anal 8-9. Pectorals reaching pelvics, 

 which are inserted below the fourth or fifth ray of dorsal and 

 reach the anal. Caudal forked. A dark stripe from snout
