HABITAT: Brazil, "Rio Janeiro, Mr. Bonifas, 1776" (_Drury's_ MSS.). _Upper Side._ Antennæ black. Head, thorax, and abdomen grey-brown. Anterior wings grey-brown, thin, and slightly diaphanous, with a small light-coloured bar running from the anterior edge near the tips to the posterior. Posterior wings having one-third next the body grey-brown, divided by a line drawn across the wings from the anterior to the abdominal edges; next to this is an angulated white patch, the rest of these wings being orange-coloured, with two black eyes, having white centres, placed one at the upper, the other at the abdominal corners, the former having a small white spot joining to its upper part. The edges of these wings are bordered with dark brown. _Under Side._ Palpi, legs, breast, and abdomen cream-coloured. Anterior wings next the tips tinged with red-brown; the remainder of the wings being of the same colour as on the upper side. Posterior wings next the body pale clay, which occupies half the wings; below which is a white bar, the remainder of the wings being dark orange: the two black eyes are very small on this side, and the white spot above them not so distinct. These wings are larger than is generally observed among insects of this tribe, and are dentated, the anterior ones being entire. PAPILIO ASIUS. Plate XXXV. fig. 4. ORDER: Lepidoptera.
