According to Suffrian this is the largest of the three or four 

 species all similarly marked, but as he described his species from 

 a single female the general size is probably no larger than that of 

 the same sex of the allied forms. I have not seen specimens of his 

 C. guttifer, or of any other species belonging to this section, which 

 agree precisely with the descriptions, and without a large amount 

 of material no certain conclusion can be arrived at as to the specific 

 differences of these closely allied forms, which are all subject to 

 great variation. Not a single specimen before me which may 

 otherwise be referred to C. guttifer has the thorax sparingly 

 punctured as Suffrian gives it ; on the contrary the puncturation 

 is fine and very close. In spite of the almost too loug and de- 

 tailed description, the author unfortunately makes no mention of 

 the position of the inner elytral basal spot, whether it touches the 

 base or is placed lower.

Eed above ; three spots on elytra, sutural margins and under- 

 side black. 



Head feebly convex, impressed in front of vertex, closely 

 and strongly rugose-punctate ; antenna? half the length of body,

 joints widened, slightly darker than the others. Thorax large, 

 strongly narrowed in front, posterior margin serrate, surface

 black. Scutellum triangular, margined with piceous. Elytra 

 narrowed posteriorly, humeral callus broad and flat ; epipleural 

 lobes well-marked ; puncturation strong, especially so at base, very 

 feeble near apex ; interstices broad, punctured anteriorly, finely 

 w'rinkled posteriorly ; basal and apical margins narrowly black, 

 sutural margins widened posteriorly into a longitudinal hand ; 

 elytral spots placed as in C. herbsti and C. guttifer. Pygidium 

 finely punctured, black ; coxa and legs red. Anterior margin of 

 prosternum feebly produced. Last abdominal segment of male 

 simple, of female with deep fovea. 



Var. a. Elytra with a transverse band at base instead of spots, 

 third spot present. 



Var. b. Posterior portion of elytra with another band. 



Var. c. Both bands more or less connected by longitudinal stripes.
