_Under Side._ Palpi, legs, breast, and sides pale clay-coloured. Anterior wings pale clay-coloured; having three irregular indented bars crossing them, from the anterior to the posterior edges. Along the external edges is a dark cloud, whereon are four or five exceeding small white eyes, and a small white spot like an arrow's point near the tips. Posterior wings pale clay-coloured, clouded along the external edges, where there are three exceeding small white eyes. A small reddish line crosses these wings from the abdominal corners to the middle of the anterior edges. All the wings are dentated; the anterior being a little angulated. This butterfly, according to Mr. Smeathman, delights to sport in the sunshine, and is frequently found in company with Pieris Calypso about cultivated spots, as old rice plantations and cassava grounds.
