PLATE IV, FIGURE 7.
Superficially resembles O. fulvofasciMa but differs from it entirely
in structure. In tIle present form, the prosternum is processed,
the humeri strongly projecting, and the eye slightly larger.
Moreover, the sculpturing of the pronotal disk 1S completely different,
the tubercles more elevated and distinct ; and humeral tubercles
smaller.
FEliALE. Elong:l.te, robust, convex; dark reddish-brown to fuscous, rathcr
thinly covered with brownish-gray pubescencc, not at all moWed. Head on front
indistinctly m(l.culate at middle each side of median line with hoary pubescence;
eye very feebly margined with s:lIne color. Pronotum above hind angles and all
anterior OIlCii maculate with brighter fulvous pubescence, the former ones indi.;.­
tinct, the latter distinct. Scutellum brown, narrowly margined with fulvous.
Elytra with II triangular median fascia of pale fulvous-gr."lY, extending abov!:
declivity frolU basal third to apical third, its apex almost attaining suture, its inno!'
portion morc brownish; apical portion of disk streaked and indistinctly maculat.e
with fulvous-gray pubescence. Body beneath fuscous, thinly hoary puhcscent,
toward sides brownish; abdomen piceous medially, covered with short, dark brown
pubescence and with hoary hairs interspersed, more or less densely so in some
places, laterally broadly vittate with fulvous-gray, vitt:!. attenuate on first ster­
nite. Legs fuscous, thinly variegated with hO:lry, fulvous, and dark brown pub­
escence; tibiae, except protibiae, indistinctly :lnd broadly annulate with hoary
pubescence lit middle; tarsal claw segment deep red on basal half, apically black or
piceous. Antennae (only two segments and basal quarter of third prescnt) piceous;
scnpe sparsely brown pubescent, rest thinly covered with hoary pubescence.
He3d minutely, densely punctnte, with a median impressed line from occiput
nearly to epistoma; front narrow and concave between antennal tubercles, minutely
punctate and nlutaceous, with a few coarse punctures at sides and below, above
middle each side obliquely imprCS5ed ; gcnae slightly vertical, sparsely but roughly
punctntej eye with lower lobe oblong-ovate, subequal in height to gena ; antennal
tubercles slightly prominent, minutely produced nt npex-. PrOllolum strongly trans­
verse; sides straight, oblique, unarmed; basal and apical transverse sulcus 8hlll­
low, the former coalescent with the broad lateral oblique ones; disk near base with
II few, scattered, fine punctures, across middle with five suhcqual tubereJes in a
nearly straight line, the median one elongate nnd placed a little more b3Sally.
Scutellum transverse; sides straight, oblique; apex retuse, the lateral angles
elevated and produced. Elytra feebly narrower posteriorly, apices sep.1rately
rounded; disk at bllse with .1 small gibbosity, coarsely, densely pUlIctate, toward
humeri n little more sparsely punctate, punctures behid middle finer and slightly
