This species has precisely the same habit as the foregoing. It 
differs from it in colour, size, in having the thorax more distinctly 
narrowed behind, the elytra in proportion to the thorax broader, 
and somewhat more acute at the apex. The body, too, is shorter 
in proportion to its breadth, and its outline obovate rather than 
oval. ‘The head, as in the preceding, is proportionally shorter 
than in C. chrysomeloides, and the antenne thinner, with their last 
joint shorter and more distinctly mucronate. 
I have seen but two specimens of this insect; one from the 
rich cabinet of my excellent friend the Rev. William Kirby, B.A. 
F.L.S., by whose name I have designated it; the other in my 
own. That in Mr. Kirby's cabinet has its antenne wholly fer- 
rugineous, but differs in no other respect, and this variation is 
probably accidental. I cannot positively satisfy myself whether 
or not the apex of the elytra has any vestige of strie. When 
the pubescence is removed, there seemed, in some lights, to be 
one or two very obsolete lines.
