Head very sparingly punctured, obsoletely longitudinally 
depressed at middle ; clypeus 
separated from face, strongly 
emarginate anteriorly ; an-

four joints flavous, third 
and fourth equal, fifth and 
following joints slightly 
widened, terminal joint long 
and slender. Thorax strongly 
narrowed anteriorly, sides 
nearly straight, posterior 
margin finely serrate, disc 
entirely impunctate. Scu- 
tellum black at base, tri- 
angular, v ith the usual fovea. 
Elytra narrowed posteriorly, the suture raised round scutellum ; 
surface very finely punctate-striate, apex impunctate, interstices 
broad and flat, a deep black round spot on shoulders and another

Larger than C. colon , Suffr., the thorax entirely impunctate, the 
scutellum flavous, black only at base, the elytra without black 
lateral margins, their surface even more finely punctured and 
without punctures on interstices. C. tetrastigma, Suffr., seems 
closely allied, but has the elytra sculptured as in C. colon , and has 
the anterior margin of the prosternum slightly produced.

Obscure dark fulvous ; thorax with an obsolete black band near 
base. Elytra with one humeral and one subapical black spot. 
2 . Large and robust. Head with two obsolete transverse 
depressions, strongly punctured, space in front of eyes and 
between antennse stained with black ; clypeus separated from the 
face, deeply emarginate in front, finely punctured ; antennae short, 
fulvous, third and fourth joints equal, fifth and following joints 
strongly flattened and widened, each not longer than the pre- 
ceding joint. Thorax extremely convex, almost subglobose, 
posterior angles produced, margins narrowly black, surface en- 
tirely impunctate, the base with a very obsolete transverse black 
band. Elytra very slightly narrowed posteriorly, the suture 
raised round scutellum ; surface moderately strongly punctate- 
striate, punctures distinct to apex, intermediate rows shortest, 
each preceding and following row joined at apex ; epipleural lobes
