Adults. Antennae of males simple; simply-ciliate. Face rough (with a short cone of scales).

Wingspan 26–40 mm. The outer margin of the forewing slightly sigmoid-curved, or convexly curved. Forewings ochreous to dark brown, or pale fuscous; predominantly ochreous, or brown, or pale fuscous; with a clear discal mark (this dark). The discal mark not dark-ringed. Forewings with a distinct median band to without a median band (the band darker, if distinguished). The outer margin of the hindwings scalloped. Hindwings conspicuously patterned (P. transversata), or plain (P. vetulata); coloured similarly to the forewings; with a clear discal mark, or without a clear discal mark; transversely lined (these faint in P. vetulata).

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 Rhamnus.

British representation. 2 species; South-east England, Central-southern England, South-west England, English Midlands, Northern England, and Wales. Living adults found June and July. P. transversata (Dark Umber), P. vetulata (Brown Scallop).

Subfamily. Larentiinae.
