130 THE TRIBE ONCIDEnINl
Distinguished by the small size; the elytl'a elongate, their sides
straight, gradually tapering apically, disk simply punctate j pronohllIl
narrower at apex, subcylindricaJ, sides unarmed; antennae
with scnpe rather cylindrical, gradually clavate apically, third
segment slender, feebly sinuous j humeri somewhat clawed in appearance,
anterior margin being arcuate and oblique, the angle
with a small tubercle.
Elong.:tte-ovnte, moderately robust, small or moderate-sized; fu$Cous or dark
reddish-brown. Head with front about as brood as high, slightly narrowed below
from lower margin of eye; gena. elongate; eye with lower lobe elongntc-ovate,
slightly shorter than gena in height; antennal tubercles moderately prominent, well
separated, with a subac\lte process at apex ill male, very feebly annoo in female.
Pronotum transverse, suheylindricaJ, unarmed laterally, apex narrower than base;
disk tubereulate at middle, on sides tumid, each tumescence more or less bitubereu­
late. Scutellum transverse. Elytrn. with sides str!"light, gradually attenuate apic­
ally, apices separately rounded; basal gibbo@ty rather feeble, disk auteriorly with
simple punctures; humeri prominent, anterior margin strongly arcuate and oblique,
angle with 11 moderate-sized, obtuse tubercle. Prosrnum simple, gradually widened
behind middle; mesosternal process slightly longer than wide, apex feebly emargin­
ate. Fifth sternite slightly longer than fourth, apex emargillate in male and female,
in the latter sex there is a triangular impression medially. Pl'ocoxae globose, in
male anteriorly armed with an obtuse tllhercle or feebly curved uncus; femora
robust, ck\.v!"lte, in male profemora transversely rugose basally; prot.arsi feebly
dilated ill male. Antennae about one and one-quarter times as long as body in male,
as long as body in female, slender; scape robust, not. quite attaining middle of pro­
notum, gradually, not strongly elavllte apically, in male not rugose nor grooved at
basc; third segment one and one-third 't imes as long liS first, moderntely bisinuous;
fourth slightly shorter than third, fifth noticeably shorter than fourth, rest gradu­
ally sIlOrter.
