nullis, sed medio utrinque levissimé sinuato. Ale apice fusce. — Coleoptra ob- 
longo-ovata, thorace feré tripló longiora et in medio pauló latiora, pube-derasä,

Var. f. griseo-fusca, capite thoracisque disco obscurioribus ; 
. thorace pube fulvescente, elytris, grisescente, vestitis. 
An species distincta ? 
Of this species I have seen two or three specimens of each sex. 
They exhibit no other than the usual sexual differences. The 
females are slightly larger, and their antennz a little thicker and 
longer.—There can be no danger of confounding this with any 
species of the two preceding sections. In habit it approaches 
nearest to C. tristis; but the resemblance is superficial merely, 
there being a wide difference in the form and structure of the 
antenn: and thorax, as the description of each has indicated.— 
The elytra of this insect have no appearance of striæ except the 
pubescence is scraped off, when a few faint traces are generally 
to be observed.—The antenne vary with respect to the colour 
of the base. In some only the base of the first joint is reddish 
brown; in others the two first joints, and in one specimen the 
first six joints, were wholly of this colour.—In the female they are 
thicker than in any other species of the genus.—The lateral mar- 
gins of the thorax are rounded from the apex almost to the base, 
but close to the base they are nearly straight and parallel. To 
see this character a microscope and a keen eye are requisite, 
especially if the thorax be clothed with the usual thick pu- 
bescence. 
Panzer's figure appears to be intended for this species, though 
neither the antennz nor the basal margin of the thorax are cor- 
rectly drawn, and the feet are coloured wholly yellow.—Latreille’ s
