Elongate-ovate, small to moderate-sized, ranging from about 8–13 mm in length. Integument generally dark brown with whitish, ferrugineous, black, and ochraceous pubescence. Head with frons elongate, narrow, about as wide as width of one lower eye lobe. Eyes with lower lobes large, oblong. Genae subquadrate to elongate, distinctly shorter than lower eye lobes. Antennal tubercles prominent, moderately to narrowly separated; tubercles not armed at apex (females) or armed with a small projection, or with a short, blunt horn (males). Antennae about as long as overall body length, or as much as 1 1/3 times as long; scape clavate, about as long as antennomere IV; antennomere III sinuate, longer than scape and antennomere IV. Pronotum transverse, roughly cylindrical to distinctly conical, wider at base, without lateral tubercles. Elytra with sides roughly parallel to attenuate; elytral apices individually rounded; elytra generally uniform in coloration or with distinct maculae; base of elytra with two prominent tubercles at humeri. Basal 1/3 of elytra with dense punctation, surface coarsely punctate to granulate-punctate; punctures in some species distinctly large. Procoxae without projection (females) or with distinct, curved hook (males). Mesosternal process with apex deeply emarginate. Metafemora long to moderate in length, about 1/2–1/3 as long as elytra.
The combination of the following characters will help to distinguish this genus: form ovate; large eyes; basal 1/3 of elytra with dense punctation, punctures in some species distinctly large; and moderate to long metafemora.
Strongly resembles Lydipta but the elytral punctation is distinctly larger and the pronotum is more strongly conical in Euthima.
