Head black, the neck shining, the vertex and front opaque, the latter strongly 
produced between the eyes, its hinder dorsal surface with three short longitudinal 
sulci, the anterior upper surface with a narrow, distinctly raised longitudinal ridge. 
Antenne half the length of the body, robust, rigid, slightly compressed, attenuated 
towards the apex, the apical joint very acute ; basal joint slightly thickened, submoni- 
liform, the second very short, subturbinate, the third and fourth each about twice 
the length of the second, the fourth being rather shorter than the third. Thorax 
transverse at the base; conic, the sides obliquely converging from base to apex, obso- 
letely bisinuate, anterior angle armed laterally with a short acute setiferous tooth ; 
basal margin deeply sinuate on either side; above subcylindrical, broadly depressed and 
excavated on the hinder disc, irregularly foveolate on the sides and apex; a discoidal 
vitta, abbreviated anteriorly, together with the lateral margin, nigro-piceous or black. 
Scutellum oblong-quadrate, its apex obtuse. Elytra narrowly oblong, gradually but 
slightly increasing in width from the base towards the apex, basal margin strongly 
lobed, the lobes received into the excavations of the thorax; sides rather strongly 
serrate; apical margin obtusely rounded, irregularly denticulate and armed on each 
elytron with four or five spinous teeth; above rather coarsely granulose-punctate, each 
elytron with ten regular rows of deep punctures ; second and fourth interspaces strongly 
costate, nitidous ; basal portion of the sixth interspace, together with the entire eighth, 
less strongly raised, the latter obsoletely serrulate. 
C. normalis, Chapuis, an insect which I have not seen, appears to be closely allied 
to the present species.
