middle, the inner afm is longer and narrowly ntttl.ins the suture; disk with scattered,
small, rounded, obsolete maculae of darker pubescence, each surrounding a deep
puncture. Body beneath entirely covered with dellsc, paJe fulvous-gray to brown
pubescence; metcpisterna often with a pale macula on the external basal angle. Legs
and antennae fusoons to black; pubescence similar to that of body.
Head with a median impressed line from occiput extending nearly to epistorna;
front minutely punctate, concave between the antennal tubercles; genae vertical,
minutely punctate ; eye with lower lobe oblong, subequaJ in beight to gena ; antennal
tubercles feeble, appro).imate, unarmed at apex. PrQnotum slightly transverse,
base wider than apex, sides feebly curved, unnrmed; with an apical and a basal
transverse sulcus; disk at middle with a longitudinal carina from ixlsal sulcus to
apical sulcus, either side of which behind apical sulcus is a very small tubercle
ncar base, on each side an oblique sulcus, extending beneath lateral margin. Scutellum
transverse, sides nearly straight, feebly oblique, npex very broadly rounded.
Elytra. with sides strongly tapering posteriorly, apices separately rounded; disk
at middle of each base with lin arcuate, strongly clevated crest, ruulling for nearly
a third of the length of the elytron, in its apex set with a single row of distinct,
shining grnnules, rest of surface of disk with small, distinct, scattered punctures;
humeri variable in their degree of prominence, always somewhat so, anterior margin
straight, strongly oblique, the nngle with a lnrge tubercle. Prosternum nrcuate1y
widened medially between the coxae. Procoxae tumid and with a fold posteriorly,
anteriorly feebly tuberculatc; mesocoxae with It short, distinct, obtuse tubercle
anteriorly; femora robust, feebly clavate, profemora strongly, transversely rugose
above and below; metatibiae much swollen on apical two-thirds, internally with an
elongale-oval, glabrous patch, extending the length of the swollen portion; protarsi
strong dilated, mesotarsi slightly 80. Fifth stemite one-third longer than fourth,
apex emarginate. Antennae about as long as, or a little shorter than, body,
fringed, beneath from first to fourth segments; scapc elongate, slender, gradually
clavate; third subcqual to first in length, feebly bisinuate; fourth only one-half
as long as third, rest gradually shorter.
FEMALE. A little more robust; eye with lower lobe distinctly shorter than
gena; antenll31 tubercles slightly more feeble; femora more slender, profemora not
rugose; metatibae not enlarged, without a glabrous area; fifth sternite about
twice as long as fourth, apex rounded, with Ii feeble triangular impression; antennae
about two-thirds length of body, a little less robust t.hll.n male, otherwise similar,
third slightly shorter than seape.
