52 THE TRIBE ONCIDERINI
Elongatovate, rather robust, convex. Head with front elongate, graduaHy
narrower above; gena vertical; eye with lower lobe broadly oblong, about equal
in height to gena ; antennal tubercles prominent, suhcontiguous, at apex with a
long, robust, obtuse tooth in male. Pronotum transverse, conical, narrowed anter­
ioriy; sides unarmed; disk with five tubercles. Scutellum transverse. Elytra with
sides feebly attenuate; apices separatcly rounded; basal gibbosities elongate, well
elevated; disk on basal third sparsely, coarsely granulate-punctate; humeri pro­
jecting, with a prominent, rounded tubercle at angle. Prosternum simple, widened
medially; mesosternal process slightly emarginate laterally, apex deeply emarginate.
Legs moderate in lengt.h; procoxae globose, anteriorly with a short, stout uneus
(male) ; femora robust, gradually clavate; metatibiae feebly expanded in male;
protarsi slightly dilated in male. Antennae about two-thirds again as long as
body in male; scape reaching nearly to middle of pronotum, slightly arcuate,
gradually clavate apically; third segment elongate, nearly one and one-half times
as long as a scape, feebly hisinuate; eleventh segment in male distinetly longer
than tenth, with a short, curved, apical process.

MALE. Elongate-ovate, slightly robust, convex; fuscolls, entirely covered with
dense, hoary-gray or whitish pubescence, sparsely moWed on pronotum and elytra
with dark brown. Scutellum dark brown, narrowly rimmed wit.h hoary pubescence.
Elytra more or less distinctly banded witb broken, oblique, glabrous patches, one
indistinct behind humerus, another most distinct behind middle, and a third just
before apex. Body beneath and legs entirely fuscous, densely hoary-gray pubescent,
the latter more thinly so; abdominal stcrnites each with a single small, brown
macula toward each side, the fourth broadly at middle, the fifth at apex, maculate
transversely with dark brown. AntenMe fuscous, annulate basally with hoary­
gray pubescence, annulation coverillg two-thirds of third, half of fourth, and gradu­
ally reduced on foliowing segments.
Head minutely, not densely punctate, with a median impressed line extending
from occiput neariy to epistoma ; front very narrow between antennal tubercles,
gradually widened below, finely punctate, with coarse, deep punctures interspersed;
gcnae vertical, finely and sparsely punctate, with several coarser punctures inter­
mixed; eye with lower lobe broadly oblong, about equal in height to gem,; antennal
tubercles prominent, subcontiguoWl, terminating at apex in a long, robust, obtuse
tooth. Pronotum transverse; side nearly straight, unarmed, narrowing gradually
to apex; apical transverse sulcus deep, straight, basal one more shallow, connecting
with the lateral oblique ones; disk sparsely but distinctly punctate, with median
tubercle narrow and linear and with two strong, more or less rounded tubercles
each side close together. Scutellum transverse; sides feebly rounded, only slightly
oblique; apex broadly arcuate. Elytra with sides only slightly tapering, broadly
