Oblong, oval, rather convex, shining and finely punctate above. 

 Head and prothorax black, the latter arched laterally with pos- 

 terior angles prominent ; the edges not turned up at the base. 

 Elytra somewhat rugulose anteriorly, black, with more or less of 

 the sides and apex of a livid red colour, with punctate striae 

 second, third and fourth intervals depressed, and sensibly broader 

 at their posterior part than the sutural one. 



Var. A. Elytra entirely black except the extremity, which is 



reddish. 

 Length i to f of a line. 



This species is about the same size as the last, and when they 

 are both in their normal state of colour is easily distinguished 

 from it by the colour, the elytra of this never being yellow with 

 a black patch on the disk. Its general form also distinguishes 

 it ; it is a deeper and narrower insect, wants the tumed-up edge 

 at the base of the prothorax, and the second, third and fourth 

 intervals between the striae are wide posteriorly. The variety 

 conspurcatum, Steph., has the elytra testaceous with a triangular 

 black patch at the base like melanocephalum. 



Common. 



C. littorale, Gyll., Steph., Muls. 

 ruficorne, Kirby, Steph. 

 binotatum, Steph. 

 dilatatum, Steph. 



Oval, feebly convex, black or brownish black above, and 

 densely marked with small punctures. Epistome of the form of 

 a parallelogram, somewhat cut out in front. Prothorax as short 

 in the middle as on the sides. Elytra broadest in the middle, 

 with eleven punctate striae gradually deepening posteriorly. In- 

 tervals subconvex at the extremity. 



Var. B. Elytra bordered on the sides with yellowish red for 

 half their length, and with a patch of the same colour at the 

 apex ; a. prothorax entirely black ; /8. prothorax bordered 

 with red on the edge. 



Vai'. C. Like the preceding ; but elytra also with a reddish yel- 

 low patch at the base, sometimes extended so much as to
