Pranotum transverse, apex nhout one-third narrower than base, sides straight,
unarmed ; with an apical and a basal transverse sulcus; disk with meWan tubercle
basal, elongate, broad, very feebly elevated, a tubercle each side of middle more
apical, only moderately elevated, base with sparse, punctate granules. Scutellum
transverse; sides straight, oblique; apex truncate, notched medially. Elytra with
sides straight, attenuate to apices, which are separately and rather narrowly
rounded; disk, at base feebly gibbose, basal quarter very coarsely, deeply, sparsely
punctate, sometimes forming feeble rugosities medially, remainder of elytra with
punctures gradually smaller but no less distinct; humeri strongly projecting,
slightly elevated, conical, with a large rounded tubercle at angle. Prostermrra
rorrO\v, not. widened nt middle of procoxae. PrQCOxae prominent, unarmed; pro
femora robust, slightly clavate; metatibiae much broadened apically; protarsi
strongly wi.dened. Fiftb sternite nearly twice length of fourtb, bilobedly croar·
ginate. Antennae about one snd one-third times body length, slightly fimbriate
beneath on third and fourth segments; seape not reaching to middle of pronoturo,
rather slender; c:lavate beyond basal third ; third segment feebly biflexuose, rest
gradually shorter.
FEMALE. SlightJy more robust, less attenuate; prosternum slightJy wider ;
metatibiae not as broad; fifth sternite triangularly impressed apically; antennae
only as long or slightly shorter than body, scape more slender, clavate.

not so transverse, with five very distinct discal tubercles ; eye
with lower lobe elongate, narrow; elytra more attenuate, humeri
strongly projecting; antennae in male very elongate, one and one·
half to one and two-thirds times as long as body, distinctly longer
than body in female, third segment one-third longer than scape,
eleventh segment elongate in male j procoxae uncate in male.
Moderately small, elonglltEHlVatc, rather robust. Head with front elongate,
rather narrow, sides nearly parallel; gena elongate; eye with lower lobe oblong,
feebly narrowed below, slightly longer than genae ; antennal tubercles prominent,
suhapproximate, at apex with a short, very robust, obtuse tooth. Pronotum trans·
verse, conical, base two..fifths wider than apex; sides unarmed; disk with five
distinct tubercles. Scutellum traIl!lverse. Elytra with sides distinctly attenuate
