This Cossid moth was about 40 mm long. Fore wings were a plae grey with a central darker area. Midway along the costa was a semicircular patch of white. A short diagonal patch of dark grey was seen along the trailing edge of the fore wings. The thorax had the inverted black "V" as in all most other cossids.
Spotted under bright lights near native trees.
