the hinder one just behind the middle), one on the sixth (halfway between its middle 
and the apex), and, lastly, two on the eighth (the first elongate, near the middle, the 
second shorter, subapical); the two ridges on the humeral callus cover, one nearly the 
basal half of the sixth, the other the basal fourth of the eighth interspaces. 
This and the preceding species ought to be placed near C. marginata, Guér.

Face between the antenne with an acute tooth. Antenne rather more than half the 
length of the body, filiform ; joints cylindrical, the two lower ones short, equal. Thorax 
twice as broad as long in the medial line, its anterior portion abruptly contracted to 
nearly half its width; sides straight and obliquely diverging from the base to the 
middle, thence to the apex entirely occupied by a deep angular notch, the anterior 
border of which is nearly perpendicular and forms the lateral margin of the constricted 
half of the thorax, whilst the hinder border is horizontal and runs directly outwards to 
form an acute angle with the oblique hinder portion of the margin; apical angle armed 
with a stout subacute tooth; upper surface transversely excavated at the base, 
impressed, but rather sparingly, with large irregular punctures, medial disc nearly 
impunctate. Elytra much broader than the thorax; sides broadly dilated, obtusely 
rounded, posterior angle not produced, obtusely angulate, apical margin obliquely 
rounded; upper surface flattened between the humeral calli, the latter strongly 
produced laterally, their apices acute; each elytron with ten longitudinal rows of deep 
punctures, arranged in pairs, the inner pair abbreviated at the base, the space being 
occupied by an irregular longitudinal callosity, which extends downwards from the 
basal margin for nearly one fourth the length of the elytron; the suture, together with 
the second, fourth, sixth, and eighth interspaces, costate ; rufous, the interspaces between 
the coste black; the outer limb, an irregular fascia [dilated on the outer margin] just 
behind the middle, together with the basal callus, white; the outer limb has two 
large rufous patches, attached by their inner edges to the disc, and extending 
outwardly nearly to the lateral margin, of these one is placed before, the other 
behind the middle.
