Adults. Head rough (-haired). Eyes glabrous; ciliated. Antennae of males ciliate.
Wingspan 28–42 mm. Head and thorax coloured like the forewings, the abdomen usually lighter or like the hindwings. Forewings red-, chestnut- or dark purplish-brown, ferruginous, or ochreous, less often umber; complexly patterned; the patterning well marked to obscure; reniform defined; orbicular defined; claviform defined, or undefined. Hindwings whitish-fuscous, or fuscous, or grey; plain, or terminally darkened; with a clear discal mark, or without a clear discal mark (mostly); transversely lined, or without transverse lines; exhibiting vein 5. Vein 5 of the hindwings weak; arising nearer to vein 6 than to vein 4. Thorax crested (only slightly, anteriorly). Posterior tibiae without spines. Abdomen not crested.
Living adults found October to December, or January to March (i.e., all the species hibernating).
