basal third granulare-punctate; humeri prominent, with a large, rounded tubercle
at angle. Prosternum simple, widened posteriorly; mesosternal process short,
strongly widened apically, apex bil obedly cmarginatc. Legs modemte in length;
procoxae globose, di stinctly tuberculate, tubercle usually ending in an uncus; fe­
mora robust, gradually and strongly clavate from basal third; mesow and metatibiae
in male dilated. Antennae in male one and onc--htllf times as long as body, in fe­
male as long as, or slightly longer than, body; scape robust, attaining apical third
of pronotum, strongly clavate on apical third; third segment slightly longer than
seape", feebly bisinuousj rest gradually shorter; eleventh slightly longer than tenth

PLATE IX, PlGURE 13.
Elytra at extreme base pale, smooth, thence granulate-punctate,
without a distinct median fascia j antennae with bases of an segw
ments from third broadly pale ; and l?ronotum laterally shortly
tuberculate, before and behind tubercle a distinct impression.
:lI.lliE. Elongatew()vate, robust ; clark reddish-brown to piceous, densely cov­
ered with fulvous and hoary-gray (or pale fulvous-gray) pubescence. Pronotum
broadly tinged with light brown medially, anteriorly at mi4dle a bright £ulvous spot
and a similar one on some of the discal tubercles, wward sides largely gray. Scu­
tellum moderately dark brown, narrowly edged with grayish. Elytra largely gray,
sparsely variegated with fulvouB, behind base brown to basal third (except along
suture) and coarsely, irreguJarly mottled with the same color thence to apex. Body
bene.tth dark reddishwbrown to fuscous, rather densely, pale fulvouswgray pubescent,
toward sides more fulvou;; and mfICuiate on mcsepisternn and metepisterna with
bright fulvous or ochraceous, the latter structure strongly tinged with brown
medially; abdomen laterally brighter fulvous or ochraeeous, forming a divided
vitta or two rows of indistinct maculae each side, fifth sternite bro3dly brown at
center, the other sternitcs each with a transverse row of glabrous punctures apic­
ally. Legs dark reddishwbrown, entirely pale fulvous-gray pubescent; metafemora
medially and metatibiae basally indistinctly annulate with brown; tarsi entirely
hoary pube...--cent. Antennae fuscous, bases of fourth and following segments broad­
ly, but not distinctly, roseate; entirely hoary pubescent, except apical half of third
and fourth segments, which h3ve dark brown pubescence, and scapc, which is
covered with fulvous-gr.ay.
Head minutely, densely punctate, with a median impressed line from occiput
to clypeus; front elongate, vertical, not narrowed above, narrowly concave between
antennal tubercles, sparsely, finely punct{l.te, more dcnsely so medially; gena parw
tinily glabrous, slightly taller than wide, minutely, rather densely punctate, and
with several rather coarse punctures interspersed ; eye wit.h lower lobe elongate,
oblongwovate, about one--third taller than gem; antennal tubereles prominent, ro­
bust, distinctly separated, armed at apex with a short, robust tooth. Pronotum
