the height of gena, whereas in dola it is equal to the genal height.
Furthermore, it differs in the front being broadly vittate at middle,
(not with just two small maculae at center), in the maculation of
the elytra, and in the undersurface coloration, particularly the ab­
domen, which is nearly glabrous at middle and possesses two rows
of distinct maculae on each side.
MALE. Elongate-ovate, rather robust, above subdepressed; black, thickly cov­
ered with brownish-gray pubescence variegated somewhat with brown, pale gray,
and fulvous. Head above sometimes vittate with brown and fulvous; eye narrowly
margined with pale gray; front medially with a broad broken ochrnceous and gray
vitta running its entire height. Pronotum with several faint, pale vittle, one much
broader on each side. Scutellum brown, basal angles pale gray. Elyt-ra with apices
of many of the elevations streaked with fulvous, especially along· suture nnd basally,
an indistinct fulvous-gray macula at apical third and another larger apically. Body
beneath fuscous, fuivous-gray pubescent, laterally maculate indistinctly but broadly
with brownish and brighter {ulvons; abdomen thinly pubescent, medially nearly
glabrous, each side with two rows of fulvous mncuiae, one indistinct along margin,
the othcr well-marked, half way between margin and middle. Legs blnck, covered
by fulvous, gray, and brown variegated pubescence; tarsal claw segment nearly
glabrous apically. AntennM black, light brown pubescent, mottled with pale gray,
bases of segments from fourth annulate with gray, base of third indistinctly so.
He.'ld minutely alutaceous, a median impressed line from occiput to epistorna;
Cront broad, slightly widelled above, slightly concave between antennal tubercles,
minutely, densely punctate, with a broad band of fine punctures across middle;
genae strongly vertical, minutely, densely punctatc; eye with lower lobe oblong,
sall, not more than two-thirds the height oC gena; antennal tubercles robust,
prominent, intemally armed with a broad, obtuse horn which curvos inwardly.
Pronotum strongly tr.'lnsverse; sides broadly rounded, narrowed to apex; iflteral
tubercles feebly elevated, broad, terminating in a moderately long, robust, obtuse
process; apical trawverse sulcus broad, shallow, wal one strongly deepened at
middle and at each side, lateral oblique ones feeble; di.sk medially wi th a broad,
nearly circular, low ·tuberclc, each side strongly tumid, each tumescence traversed
by :0 curved, nearly transverse impression, base almost impunctate. Scutellum trans­
verse; sides straight, strongly oblique; apex brOildly rounded, notched finely and
slightly impresscd at middle. Elytra with sides Ceebly and gradually tapering pos­
teriorly, apices each strongly and narrowly rounded ; bas.."\l gibbosity somewhat
elongate, not very distinct, narrowing posteriorly, rest of disk with numerous linear,
irregular elevations, a rounded impress ion at apical third toward side, basal half
finely, rather densely punctate, slightly sparser behind middle; humeri prominent,
anterior m:l.rgin slightly rounded, strongly oblique, anglc with a moderate-8ized, oval
tubercle; sides behind and below humeri more coarsely punctate than disk. Pro­
sternum st-rongly expanded at middle, thence posteriorly slight.ly widened. Pro­
coxae tumid, anteriorly with a large, conical tubercle; femora very robust, clavate,
profemora coarsely rugose on basal half of posterior face. Fifth sternite only
slightly longer than fourth, apex at middle deeply emarginnte. Antennae about one
and one-Courth times the body length, eighth segment attaining elytral apex; fim
