There is an irregular black submarginal line which is expanded into blocks sub-dorsally and at one third from the costa, with a smaller block on the costa. Hindwing with a longitudinal rectangle. The caterpillar is a fungus feeder. It is dirty white with indistinct pink marbling. A pink spot is found dorsally at the rear of each segment. The head lacks setae, but with glossy tubercles.
