outlined with fulvous, apical part. of disk more silvery-gray than at base. Body
beneath fuscous, silver-gray pubescent, more or less variegawd with fulvous; pro­
thorax on sides behind procoxae with a brown area that. extends obliquely pos­
teriorly onto base of metepisternum; abdomen on middle of third and fourth ster­
nitcs brondly brown, the rest boary Ilnd fulvous, variegated witb browll, the lateral
margins pale and a row of indistinct pale maculae each side half way between
middle and lateral edge. Legs fuscous, silvery-gray pubescent., tinged with brown;
tarsal claw segment pale reddish on b..'ISal two-thirw. Antennae luscou, covered
with silvery-gray and brown pubescence, segments six and cight with basal half,
seven and nine with narrow base, pale, these paJe areas entirely gflly-pubescent.
Head minutely, densely punctate, a median impressed line from occiput to
epistor.1a; front broad, subquadratc, broadly and feebly concave between antennal
tubercles, minutely alut.'lceous, a few fine punctures along sides; genae subquadrate,
minutely alutaceous and with a few large punctures; eye with lower lobe elongate­
oblong, one and two-thirds- the height of gena ; antennal tubercles feebly prominent,
robust, widely separated, WlarmOO. Pronotulll strongly transverse, two-thirds again
. as wide as long, sides straight, gradufilly narrower apically, with a very feeble tubercle
behind middle; apical transverse sulcus obsolete mediany, at sides more
distinct, basal sulcUl! broader find deeper; coalescent with the shallow, lateral, ob­
lique ones; disk at middle on basal balf with poorly defined, feebly elevated tubercle,
each side with a distinct, nearly flat tumescence, indistinctly impressed, base
sparsely, finely punctate. Scutellum slightly transverse; sides straight. feebly ob­
lique; apex -broadly arcuat.e. Elytra feebly attenuate Ilpically; apices Mch nar­
rowly rounded; disk basally sparsely punctate with moderate-sized punctures, along
suture seriately arranged, behind middle becoming finer, nearly obsolete before
apex; humeri feebly prominent, anterior margin arcuate, strongly oblique, angle
with a small, prominent tubercle; sides below humerus to before middle more
coarsely and densely punctate than disk. Prosternum with a small, distinct, trans­
verse process; mesosternum with a broad, large tubercle anteriorly, acutely' angled
when viewed from the side. Leg.;! rather short; procoxae ununned ; femem robust,
strongly clavate, profemora very feebly rugose basally. Fifth sternite one-third
longer than fourth, transversely impressed before apex, which is broadly arcuate.
Antennae as long as body, rather slender, sparsely funbriate beneath to apex; scape
slender, gradually arcuate, feebly clavate from base; third segment slightly longer
than scnpe, feebly sinuaw; fourth equal to first, rest gradually shorter.

PLATE IX, FIGURE 8.
Very nearly identical with S. sternalis but differs from it in
having the prosternum lack all trace of a median transverse process;
the humeri with anterior margin less oblique, the angle with
a larger tubercle ; antennae with fourth segment broadly rosy at
base ; and the elytral brown lateral patch a little more distinct.
