Description: Elongate-oblong, small to moderate-sized, ranging from about 9–16 mm in length. Integument generally dark brown or ferrugineous with whitish, ferrugineous, and ochraceous pubescence. Head with frons subquadrate to elongate, about as wide as width of 2–4 lower eye lobes. Eyes with lower lobes ovate-oblong to distinctly narrow. Genae subquadrate to elongate, about as tall to distinctly shorter than lower eye lobes. Antennal tubercles prominent, widely separated; tubercles not armed at apex or armed with a small projection, or with a short, blunt horn, or with a moderately long, blunt horn (males of some species); antennae about as long as overall body length, or as much as twice as long; scape clavate, about as long or shorter than antennomere IV; antennomere III sinuate, longer than scape and about as long or longer than antennomere IV. Pronotum transverse, roughly cylindrical to conical, wider at base, without lateral tubercles. Elytra with sides attenuate; elytral apices individually rounded; elytra generally with distinct vittae; base of elytra without tubercles or with two prominent tubercles at humeri. Basal 1/3 of elytra with moderate to dense punctation, surface coarsely punctate. Procoxae without projection or with small acute projection or distinct, curved hook (males of some species). Mesosternal process with apex variable, from subtruncate to deeply emarginate. Metafemora moderate to short in length, about 1/3–1/4 as long as elytra.
The combination of the following characters will help to distinguish this genus: ovate-oblong to distinctly narrow eyes; sinuate antennomere III; elytra with sides attenuate; elytral apices individually rounded; and elytra generally with distinct vittae.
