(1'8 X 2 mm.), lightly narrowed anteriorly (ant. width 1-7 mm.),

 marked; anterior margin lightly and widely emarginate; anterior 

 angles obtuse, lightly marked; border narrow, not weaker on sides 

 of basal curve; median and anterior lines strongly impressed; lateral 

 basal impressions short, deep, narrow. Elytra wide (-i'O x 24 mm.), 

 Hghtly convex, subdepressed on disc, shortly declivous to peduncle; 

 base truncate (a little roundly); shoulders rounded: striae deep, 

 strongly crenulate, becoming lighter towards apex, first stria 

 curving in towards suture a little before base and turning out 

 towards second at basal extremity; interstices convex, depressed

 Masters.) 



Closely allied to and resembling C. felix, SI., in colour, but larger, 

 wider, and more depressed. The discoidal black patch on the 

 elytra is oval, and extends in its widest part over the four or five 

 inner interstices.

Of a slightly dviller testaceous colour than C. juvenis, the last 

 half of the elytra even more obscure than the base. The antennte 

 are more slender. The anterior elevation of the head is not 

 declivous and narrowed behind as in C. juve)iis, where it has the 

 shape of a horseshoe; the vertex has not a centi-al fovea; the 

 prothorax is a little flatter, wider, and the impressions of the 

 base are more marked and rounded towards base. The anterior 

 tibia? have only two. very short and triangular teeth above the 

 apical digitation. 



Length 7, El. 3|, breadth 1| mm.
