Adults. Antennae of males simple. Face rough.
The outer margin of the forewing slightly sigmoid-curved, or convexly curved. Forewings not predominantly green, yellow, or black; light- or light-yellowish-fuscous, or dark fuscous, with dark striae and median band; predominantly pale ochreous, or brown, or pale fuscous, or fuscous; with a clear discal mark (this black); usually with a distinct median band (this dark), or without a median band (in a dark form of L. suffumata). The outer margin of the hindwings smooth. Hindwings conspicuously patterned to plain; whitish or light to dark grey; predominantly whitish, or pale grey, or grey; not predominantly green, yellow, or black; with a clear discal mark to without a clear discal mark; transversely lined to without transverse lines (the striae rather sharp to obscure).
Vein 10 of the forewings arising independently of 9; arising independently, anastomosing with 11 and 9 to form a double areole. Hindwings exhibiting a tubular vein 5. Vein 5 of the hindwings arising from about the middle of the transverse vein, or arising from below the middle of the transverse vein (?). Vein 8 of the hindwings approximated to or anastomosed with the upper margin of the cell to the middle or beyond. Hindwing veins 6 and 7 stalked.
Posterior tibiae of males 4-spurred.
Early stages. Larvae feeding on Galium.
