IdentificationA medium-sized (4.6-6.0 cm wingspan) moth with dark forewings and red and black hindwings. The forewings are a smooth, dark rich chocolate and grey brown with several fine erratic horizontal lines. A narrow patch along the costa at the apex is lighter brown. The hindwings are deep red-orange, almost scarlet, and are crossed by a complete black median line and a wider black terminal band.
