This gigantic and heavy moth was about 65 mm long and looked like a roll of burnt paper. The fore wings had attractive blotchy patches of black, brown, grey and white with the inner margins folding over each other in a wave. The grey thorax had two short black tufts of setae. Antennae were smooth and short. The abdomen was covered with dense grey setae; it looked and felt heavy.
Spotted under bright lights near a national park.
