96 THE TRIBE ONCIDERINI
","ithout a terminal process; disk with an elongate median tubercle, strongly ele­
vated basally, each side with two rounded tubercles which arc placed in a trans­
verse row Oil apical half, base nearly impunctate; apical transverse sulcus feeble,
basal one deeper, straight, not connecting with the shallow lateral oblique ones.
Scutellum transverse, sides straight, oblique, apex nearly truncate, feebly emaT­
ginate. Elytm with sides straight, narrowing to apices, which are separately,
broadly rounded; basal gibbosity feebly elevated, disk on basal fourth finely grntm­
late-punctate, becoming simple punctures near humeri and posteriorly extending to
middle, thence punctures obsolete to apex; humeri prominent, anterior margin
nea-rly straight, scarcely oblique, angle with a large, oblique tubercle from which
extends, directly posteriorly, a straight, distinct carina onto disk, and nearly attaining
middle, from below the tubercle another earina, which is short and arcuate, ex­
tending downward; sides a little more coarsely and densely punctate than . disk.
Prosternum unarmed, narrow, gradually wider posteriorly. Procoxne strongly tumid
posteriorly, before with n prominent, corneal tubercle; femora clavate, profemora
very robust and distinctly elongate, on upper and lower faces transversely rugose;
metatibiae only slightly expanded. Fifth sternite one and one-half times the length
of fourth, apex finely retuse, not impressed. Antennae two-thirds again as long as
body, the seventh segment surpassing elytral apex, fimbriate beneath on four prox­
imal segments ; scape moderately robust, gradually clnvate, entire basal half coarsely
rugose on all sides ; third segment nearly one-half again as long as first, strongly
sinuous; fourth slightly shorter, rest subequal, but eleventh slightly elongate, with
a recurved process at apex.

FURONA Dillon and Dillon, gen. nov.
Very closely related to Plerodia, but differs in that the lower
lobe of eye is oblong, not distinctly narrowed below, not more than
one and one-half times height of gena ; humeri obtusely tuberculate
at angle and thence carinate; antennae in male from one and
one-half to one and two-thirds times as long as body; metatibiae
in male only feebly expanded apically ; procoxae in male distinctly
uncate.
Small, or moderate-sized, elongate-ovate, rather robust, subcylindrical; piceous
or dark reddish-brown, markings very indistinct. Head with front elongate, rather
narrow, feebly narrowed above; gena. elongate-vertical; eye with lower lobe oblong,
not distinctly narrowed below, slightly higher than gena; antenna! tubercles well
separated, in male with a short, robust, vertical tooth on inner side of apex, in fe­
male less distinctly armed. Pronotum transverse, conical, base much wider than
apex, unarmed laterally ; basal sulcus ob lique at sides, apical one arcuate; disk
with three tubercles, medinn one elongate, not attaining apex, one each side of
median broad, feebly elevated. Scutellum transverse. Elytra with sides very feebly
