A medium-size rather broad-winged (3.5- 3.7 cm wingspan) grey or brown-grey moth with fuscous hindwings. Females tend to be darker than males. The antemedian, postmedian and subterminal lines and the large orbicular and reniform spots are light grey and stand out against the darker grey ground. The area between the upper antemedian line and the orbicular spot and the area between the orbicular and reniform spots is sharply contrasting black. Overall the scaling is smooth and even and results in n attractive if not colorful moth.
