rather strongly, the eighth, together with the basal portion of the sixth, less distinctly 
costate ; the fulvous vitta which stretches from the base nearly to the middle of the 
elytra extends inwards from the outer border as far as the second interspace, its apex 
obliquely truncate.

Hab. Mexico, Oaxaca (Sallé). 
Vertex and front deeply trisulcate, the medial groove broad; interocular space 
strongly produced, obtusely angulate. Antenne filiform, robust, about equal in length 
to the head and thorax ; second joint slightly shorter than the basal one, moniliform ; 
third joint nearly twice the length of the second. Thorax transverse, subconic; sides 
strongly converging from the base to the apex, bisinuate, their posterior angle obtuse, 
the anterior one produced into a short obtuse tooth ; upper surface transversely convex, 
rather deeply excavated behind the middle, opaque, impressed, but not very closely, 
with large shallow ill-defined punctures, which are rather more crowded on the sides. 
Elytra sculptured as in C. contubernalis, with this exception, that the interstices between 
the punctures are less thickened and less distinctly reticulating with each other; the 
rufo-fulvous vitta, which stretches inwards from the outer margin nearly to the suture, 
is continued downwards on the outer border and along the first costa to below the 
middle of the elytra. .

Vertex shining, impunctate; front rather strongly produced, 5-sulcate, the inter- 
mediate pair of sulci ill-defined. Antenne half the length of the body, filiform ; basal 
joints subovate, slightly thickened, the second shorter than the first, nodose; third 
joint equal in length to the preceding two united, the sixth distinctly shorter than 
either the fifth or seventh, the eighth to the tenth equal in length, the eleventh rather
