denser; humeri somewhat projecting, the anterior margin straight, oblique, the
angle nearly right angular, armed with a broad, feeble tubercle, from which a
distinct carina extends posteriorly, attaining middle of elytra; sides punctate as
disk. Prosternum medially with a broad, transverse process between coxae. Pro­
coxae tumid and transversely rugose behind, anteriorly with a broad, feeble tub­
ercle; femora robust, strongly clavate, profemora minutely alutacoous beneath at
base; metafemorn, as well as middle ones, strongly thickened from before middle.
Fifth sternite more than half again as long as iourth, apex narrowly retuse, medi­
ally with an elongate triangular impression. Antennae largely wanting; scape
slender, gradually capitate on apical twofifths.

PLATE IV, FIGURE 8.
Somewhat related to C. pallida but the median fascia of elytra
is much less distinct; scape more robust, less abruptly clavate api
cally ; eye slightly longer than gena ; antennal tubercles with the
teeth very obtuse; and tarsi with claw segment at base pale red
dishbrown.
:MALE. Elongatc-ovate, robust, convex; dark reddishbrown or fuscous, covered
with hoary-gray and fulvous pubescence, sometimes mottled. Head with eye
narrowly margined with brighter fulvouB. Pronotum each side with a short streak
of fulvou&-gray above hind angles and another on front angles. Elytra largely
fulvOllS pubescent, medially with an indistinct, oblique, whitish fascia, which is
sometimes interrupted; toward apex near suture an irregular, large patch of
white. Body beneath reddish-brown, densely covered with fulvousgray pubes­
cence, somewhat indistinct.ly mottled with darker, at middle entirely hoary pubes­
cent; abdomen medially fulvous-grIlY, more strongly mottled than sterna, laterally
indistinctly vittate with brighter fulvous. Legs reddish-brown, thinly clothed
with grayish and fulvous pubescence; tibiae very indistinctly annulate at middle
with grllyish pubescence; tarsal claw segments on apical half fuscous, the base deep
rosy. Antennae fuscous, dark brown pubescent, variegated slightly with hoary
pubescence; basal two-fifths of third and following segments pale rosy-yellow,
thinly grayish pubescent.
Head minutely, densely punctate, with a fine median line from occiput nearly
to epistoma; front narrowly concave between antennal tubercles, minutely, densely
punctate, with sparse, fine punctures interspersed; genae slightly elongate, ver­
tical, sparsely and coarsely punctate; eye with lower lobe oblong, slightly longer
than gena ; antennal tubercles well separated, prominent, at apex with a feeble,
obtuse tooth. Pronotum strongly transverse, sides feebly arcuate, unarmed, nar­
rowing to apex ; apical transverse sulcus rather deep, basal one shallower, con
llooting with the lateral oblique ones, which are also shallow; disk finely and sparsely
