angle into a sharp carina, which extends almost up to the 
anterior border; with two very small transverse tubercles, 
one on either side of the carina, on the anterior part of the 
disk ; with a broad and very feebly raised tubercle on each 
side near the base; the sides of the prothorax thickly and 
rugosely, the disk less thickly, punctured. The elongate 
spot placed just below the shoulder of each elytron does not 
touch the outer margin. Of the two spots, placed obliquely 
behind the middle of each elytron, the anterior and outermost 
is small, the posterior and inner rather large. Intermediate 
femora unidentate, the posterior bidentate at the apex. ‘Tibive 
spined at their outer termination. Intermediate cotyloid 
eavities open on the outside. 
This species must have some resemblance in the style of 
marking of the elytra to C. sexrmaculatum, Buq., and to OC. 
Chabrillact, Thoms.; but from other described characters of 
those species I am led to believe that the present species is 
quite distinct.

Fuscum, griseo-pubescens ; prothorace grosse, dense subrugoseque 
punctato, lateribus leviter rotundatis ; disco trituberculato, tuber- 
culis parvis, glabris, nitidis ; elytris fuscis, opacis, sparsim albo- 
setosis; utrisque maculis duabus testaceis (una ante medium 
literee z simulante, altera prope apicem rotundata); apicibus 
obliquiter truncatis, sutura minus productis et breviter spinosis, 
angulis externis modice spinosis; antennis corpore sesquilongi- 
oribus.

Head, thorax, underside of body, legs, and antenne with 
a not very thick coarse pubescence. Prothorax very strongly 
and thickly punctured, slightly rounded at the sides, narrowed 
towards the base and apex ; its greatest width scarcely greater 
than its length along the median dorsal line; the disk with 
three feeble, glabrous, shining tubercles. Elytra dark brown, 
dull, furnished with minute white sete, and with some longer 
white seta arranged somewhat in longitudinal rows. The 
four posterior femora are each unidentate at their apex; the 
tibie are each feebly spined at their outer distal extremity. 
The little projecting process of the antero-lateral part of the 
mesosternum is very distinct, though it does not completely 
cut off the epimeron from the intermediate cotyloid cavity.
