Male.—Above, white, upper wings with the costa dusky, and a black border at the apex regularly curved within, enclosing two small white spots and terminating in a point at the outer angle; Lower wings with a narrow hind border, not reaching the outer angle. Beneath: a row of five apical spots, the two uppermost of which are largest and yellow, the base of the lower wings yellow tinged, and the hind border enclosing a line of narrow yellow spots. Female.—Above, white, with a much broader dusky border to the anal angle, the base of the uppers dusky, and a band at the end of the cell connecting the costa with the outer border. Beneath, there is a band of six spots near the outer margin of the uppers, the second and third being larger and yellow; the base of the wings, the anal margin, and several marks between the nervures, are also yellow; the posterior band is much broader, its inner margin straight and just beyond the end of the cell, and has a submarginal row of six horizontal yellow spots. Expanse of wings 2 and 3/8 to 2 and 5/8 inches.The wingspan is 50 mm. Hab.—Waigiou (Coll. Wall.).

This is very near dice, which seems intermediate between this and gabia. It is curious that all should be found in the same small island. The upper side of. dice is, according to Vollenhoven’s description, like my male, and the under side like my female. ^[1]

The larvae feed on Notothixos leiophyllus. The larvae spread silk around the leaves where they are feeding.
