Description: Elongate-oblong, small to moderate-sized, ranging from about 11–20 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 two lower eye lobes. Eyes with lower lobes oblong. Genae variable in shape, from elongate to transverse, 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; 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 variable in shape, from nearly straight to curved to sinuate, longer than scape and antennomere IV; antennomere XI shorter than X (females) or longer than X (males). Pronotum transverse, roughly cylindrical, with lateral tubercles. Elytra with sides roughly parallel to attenuate; elytral apices individually rounded; elytra generally uniform in coloration or speckled, or with distinct maculae; base of elytra with two prominent tubercles at humeri. Basal 1/3 of elytra with moderate to dense punctation, surface coarsely punctate to granulate-punctate. Procoxae without projection or with distinct, curved hook (males). Mesosternal process with apex feebly 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: large eyes; roughly cylindrical pronotum, with lateral tubercles; base of elytra with two prominent tubercles at humeri; and elytra with sides roughly parallel to slightly attenuate.
