one along margin, one between this and middle, central portion of second, third, and
fourth sterllites golden brown, but only narrowly so on the second, the fifth vittate
each side of middle with this same color; femora above tinged with ochruceous, the
apices more or less annulate with denser pubescence. Antennae reddish-brown,
thickly covered with brown pubescence, bases of segments from third annulate with
pale fulvous-gruy.
Head above minutely 1l.lutaceous, with a median line from occiput to cpistorna ;
front of nearly equal width throughout, not widened 1l.bove, between antennal tu­
berclcs broadly concave, disk minutely aiutaceous, with a number of fine punctures
over entire surface; genae vertical, minutely aiutaceous, not at all punctate; eye
with lower lobe elongate-ovate, slightly exceeding gena. in height ; antennal tubercles
prominent, robust, widely separated, apically armed with a broad, acute tooth. Pro­
notum rather strongly transverse, narrowed distinctly anteriorly; lateral tubercles
broad and feeble, with scarcely a terminal process ; sides before middle only slightly
tumid; apical and basal transverse sulci narrow, deep, the latter coalescent with
broader and deeper lateral oblique ones; disk medially with a low ovate tubercle,
the sides entirely occupied by a prominent, subglobose tumescence, which is tra­
versed behind middle by a feeble transverse impression; entire base with scattered
fine punctures. Scutellum strongly transverse; sides arcuate, very oblique; apex
truncate, interrupted by .'I deep but narrow central impression. Elytra with sides
gradually narrowing to apices, which arc separately, angularly rounded ; basal gib­
bosity distinct but not prominent; disk at extreme base rather broadly smooth,
thence finely, deeply, irregularly punctate to apex, punctures behind middle shal­
lower and denser, each apical portion with two or three very faint costae; humeri
slightly projecting, anterior margin straight, strongly oblique, angle with a moderate­
sized tubercle, from which extends a yery indistinct carina; sides below and behind
humeri coarsely rugose to middle, thence finely punctate. Prosternum. simple, grad­
ually expanded posteriorly from before middle. Proeoxae slightly tumid behind,
anteriorly with a moderate-sied conical tubercle; femora clavate, profemora not
rugose. Fifth sternite about one-third longer than fourth ; apex broadly retuse, a
deep triangular impression medially. Antennae distinctly longer than body, the
eighth segment attaining elytral apex; beneath fimbriate to apex but very sparsely
so after fifth; scape short, slender, fecbly clavate, not rugose; third segment nearly
twice as 1011g as first, broadly and feebly bisinuous; rest gradually shorter ; eleventh
very bri efly tufted at apex.
