PLATE IV, FiGUHE 3.
Somewhat related to C. hebes but elytral median pale fascia is
broader, more distinct ; basal half of third antennal segment and
at least basal third of following segments pale; and humeri shortly
carinate.
MALE. Elongate-ovate, robust, convex; dark reddish-brown to fuscous, en­
tirely covered with thin, dun grayish-brown pubescence. Head bclow eye, and front
with indistinct m[lcube of paler pubescence. Pronotum sometimes with small,
irregular maculae of paler pubescence. Elytra each just before middle with an
oblique, strongly undulating line of creamy-white pubC.'Jcencc, extending toward,
but not attaining, suture, und a shorter similar line at apical third, not oblique,
atUlining middle of disk, between 1.he two lines are two indistinct, small macube,
lying within the sinuaLions; a large irreb'Ular macula of hoary pubescence at suture
just before apex; each with an indistinct brown band outlining front margin of
median line and several short longitudinal lines and dots between apical line and
apex. Body beneath reddish-brown, pale dull brownish-gray pubescent, with scat­
tered, indistinct maculae of paler pubescence, one especially dist.inct on mesal end
of mesepimera; abdomen fuscous, thinly clothed with short, dull grayish-brown
pubescencc, laterally broadly vittate with fu]vous-gray, vitta narrow on first stcr­
nite, sometimes with a transverse streak of same color on the third and fourth
segments apically. Legs dark reddish-brown to fuscous, thinly and irregularly cov­
ered with pale gray pube:cence; femora annulate at apex with fu]vous-gray; tarsal
claw segment with basal half testaceous. Antennae fuscous or black; basal half of
third segmcnt and bases of following segments distinctly yellowish or roseate;
clothed with dark grayish-brown pubescence, hoary pubescent on pale portions
and on basal two-thirds of scapc and on cntire second scgment.
Head minutely, dene1y punctate, '\'jth a fine median line from occiput to
epistorna; front narrowly concave between antennal tubercles, densely, minutely
punctate, with a number of scattered, modcrately coarse punctures interspersed;
genae vertical, minutely alutaceous and with a few coarse punctures more or less
seriate, sparsely pubescent ; eye with lower lobe broadly oblong, distinctly shorter
than gcna; antennal tubercles subapproximate, prominent, shortly, robustly dcntate
at apex. Pronot.um transverse; sides nearly straight, gradually narrowed anter­
iorly, unarmed; disk with five prominent tubercles, the median one least elevated,
wider behind, lateral ones least elongate, slightly oblique, a few coarse punctures
basally; apical transverse sulcus distinct, straight, basal sulcus shallow, rather broad,
short, connecting with the equally shallow lateral oblique sulci. Scutellum trans­
verse ; sides straight, strongly ob liquc; apex rounded, wit-h a strong projection
or tubercle each side, Elytra with sides nearly straight, feebly attenuate, apices
each broadly rounded ; base of each disk behind scutellum brondly and moder­
ately gibbosc, entire basal half with irregularly scattered, rather close, coarse. very
shallow punctures, apically with several feeblc costne; humeri prpminent., oblique,
with Il. broad, feebly elevated tubercle at the angle, from this tubercle e:-.iencis a
short distinct carina, running briefly oblique, thcn directed posteriorly, its entire
length only slightly greater than anterior margin of humerus; sides below humeri
