Aragonia, Arcyonia, Dyscymatoge, Encymatoge, Eucymatoge, Leucocora, Tarachia, Tephroclystia.
Adults. Antennae of males simple; simply-ciliate. Face rough (with a short cone of scales).
Wingspan 16–28(–36) mm. Forewings relatively narrow-elongate to relatively broad. The outer margin of the forewing convexly curved, or convexly curved to more or less straight. Forewings not predominantly green, yellow, or black; diverse in colour but not green, usually more or less conspicuously transversely patterned; predominantly whitish, or pale ochreous, or ochreous, or cream, or light brown, or brown, or pale fuscous, or fuscous, or pale grey, or grey; with a clear discal mark, or without a clear discal mark; with a distinct median band (very rarely, with a dark band - E. pulchellata), or without a median band. The outer margin of the hindwings smooth. Hindwings conspicuously patterned to plain (like or unlike the forewings); diverse in colour but not green, like or somewhat unlike the forwings; not predominantly green, yellow, or black; with a clear discal mark to without a clear discal mark; transversely lined (usually, the lines sharp to faint), or without transverse lines.
Vein 10 of the forewings arising independently of 9; arising independently, anastomosing with 11 and 9 to form a double areole (in Eucymatoge), or arising out of 11 and anastomosing with 9 to form a simple areole (mostly). 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.
The abdomen conspicuously patterned, or plain.
Early stages. Larvae feeding on foliage, flowers and seeds of diverse Dicot herbs and trees, also conifers.
