PLATE IV, FIGURE 6.
Closely related to C. cruda but differs in having pronotum en­
tirely unarmed laterally, and all discal tubercles elongate; scutel­
lum with apex much more strongly produced and elevated each
side; elytra with basal gibbosities more prominent, punctation
finer and sparser, median fascia narrow, not attaining suture, post­
humeral carina distinct and attaining middl e ; and entire surface
less visibly mottled.
MALE. Elongate-ovate, robust, convex; fuscous or piceous, covered with dark
brown pubescence and variegated with pale fulvous-gray. Head above largely
fulvous-gray pubescent, each side of vertex usually with a slightly oblique streak
of brown pubescence, widened gradually toward occiput, which it does not attain.
Front and prothorax most.ly dark brown pubescent, variegated slightly with fulvous·
gray, the latter especially so along base and apex. Sautellum tinged with fulvous·
gray pubescence apically. Elytra thinly d!lrk grayish-brown pubescent on basal
half, at middle of side margin an indistinct grayish spot, above and anterior to
which, beginning at the lateral carina, is an arcuate, whit.ish line, thi s line runs
obliquely beyond middle of disk, where there are several paler forks, then curves
posteriorly, terminating at apical third, from the apical fourth sublaterally a less
distinct, broken, undulating line ascends to the apex of the anterior streak, the
endosed area indistinctly fulvous-grayish pubescent, streaked with brown, the
entire apical region is fulvous-gray, irregularly mottled with brown. Body beneath
fuscous, rather thinly fulvous-gray pubescent; abdomen medially covered with
sparse, dark brown pubescence, with numerous hoary hairs interspersed, each side
broadly vittate with fulvous, the vittae narrowed on first srernite and attaining
the apex of fifth. Legs fuscous, thinly hoary pubescent; femora mottled irregularly
and coarsely with dark brown, the apices fulvous; tarsi with claw segment rosy-
