 pai'allel on sides; upper surface densely and strongly punctate: 

 elytra parallel, finely punctate-striate; four inner strite free, fifth 

 joining sixth at base; interstices depressed, eighth carinate at 

 apex, and shoulders; anterior tibiae 4-dentate. Elytra ferruginous- 

 red; prothorax and head piceous, under surface piceous. 



Head convex and smooth on vertex, a few fine punctures on 

 anterior part of front: clypeus with median part truncate, its 

 angles prominent, triangular; wings wide, subquadrate, hardly as 

 advanced as angles of median part, external angles strongly 

 marked, obtuse at summit, external mai-gin straight; supra-antennal 

 plates large, projecting shai'ply and strongly beyond wings of 

 clypeus; facial carinse hardly marked; eyes convex, not at all 

 prominent, weakly enclosed behind. Prothorax longer than

Hab. : West Australia — King George's Sound (unique, sent by 

 Mr. Masters). 



Allied to C. dor satis, Blkb., from which its colour and the 

 prothorax with the whole of the disc punctate at once distinguish 

 it; the angles of both the median part and the wings of the 

 clypeus are far more prominent than in C. dorsaiis
