sent me (^ 9 originally as such and Mr. Rivers has succeeded in ob- 

 taining and mating freshly hatched specimens. I'his species is rare in 

 collections partly from its being frequently confused with C . plant/rons 

 from which it may be easily known by the frontal carina and by the 

 pubescence at the scutellum. In ///«/// o«j the scutellum only is cov- 

 ered with vellow pubescence, while m oblileralus the base of the elytra also 

 is densely clothed for some distance on each side.

Brownish, above and beneath with more or less white pubescence

Black or brown pubescent above and beneath with lighter hair. The 

 markings are very variable but the yellow wavy line running from suture 

 and lorming the included mark seems to be constant and peculiar to the 

 species.
