dull fulvous variegated pubescence; tarsi sparsely hoary pubescent. Antennae fulvous,
distal segments much paler, entirely hoary pubescent, apices of fourth to
seventh segments somewhat mottled with brownish, scape and third segment variegated
with dull fulvous.
Head minutely punctate, with a median line from occiput to epistoma; front
broad, subquadrate, broadly and feebly concave between antennal tubercles, minutely,
densely punctate, without larger punctures or impressions; genao vertical,
minutely, densely punctate and with large, feebly impressed, scattered punctures;
eye with lower lobe elongate-oblong, narrowed below, one and one-fourth times the
height of gena; antennal tubercles widely separated, robust, feebly prominent,
inner side of apex with along, narrow tooth (or very short horn), curved laterally.
Pronotum strongly transverse, two-thirds again as wide as long; sides broadly arcuate,
gradually narrower apically, behind middle a feebly elevated, small tubercle,
without a process; apical transverse sulcus sinuous, feebly impressed, basal one
broad, moro distinct, coalescent with the indistinct, lateral oblique ones; disk with
an elongate, feeble elevation at middle, each side broadly, not very strongly tumid,
base and sides coarsely, sparsely punctate. Scutellum small, strongly transverse, sides
straight, slightly oblique, apex truncate. Elytra with sides straight, very slightly
tapering to apices, which are separately, angularly rounded; disk with coarse punctures
arranged compactly, more or less in irregular rows, on apical third punctures
abruptly finer, with soveral very indistinct costae on apical two-thirds; humeri
scarcely prominent, anterior margin rounded, strongly oblique, angle with a small,
prominent tubercle. Prosternum simple, convex, gradually wider posteriorly; mesosternum
anteriorly with a large, right angular tubercle. Legs rather short, robust;
procoxae slightly tumid posteriorly, unarmed before; femora very robust, strongly
clavate, profemora coarsely rugose at extreme base of posterior face; tibiae equally
robust; protarsi dilated. Fifth sternite slightly longer than fourth, apex broadly
retusc. Antennae rather slender, slightly longer than body, sparsely fimbriate be
neath nearly to apex; scape moderately robust, arcuate, gradually clavate almost
from base, not at all rugose; third segment one and one-half times length of first,
robust, nearly straight; fourth as long as scape, rest gradually shorter.

Closely related to Hesycha but differs from that genus in being
more attenuate j antennae having the third and fourth segments
much heavier than others (especially in male) j mesosterna! process
apically retuse j disk of pronotum much less swollen j eye with
lower lobe much larger and oblong.
