This species has the upper surface of the wings more richly coloured than any of the others captured by Mr. Oates, being of an orange-carmine colour, especially in the hind wings. The fore wings are marked half-way between the end of the discoidal cell and the tip of the wings with a square vitreous spot, through which runs a veinlet dividing it into two parts; the base of the wings, especially in the hind parts, is irrorated with black scales; the discoidal cell has a rather large oval black spot beyond its middle, followed by a smaller lunate one at the extremity of the cell; beyond which is an oblique row of five conjoined black dots; another round black spot is placed towards the base of the wing behind the median vein, and two other circular ones behind the extremity of the cell placed transversely; the veins at the extremity of the wings are slenderly black: the hind wings are marked with about 10 minute black dots (varying, however, in size), and the hind margin of the wing is rather broadly edged with black. On the under side the fore wings are rosy coloured, with the spots of the upper side, including the vitreous spot, reproduced: the hind wings are greyish buff, with the spaces between the veins varied with rosy at the base and along the anal margin, and with rich orange between the middle of the wing and the row of submarginal black lunules, which latter rest upon a narrow yellowish buff margin; the spots on this side, about 17 in number, are distinct, appearing partially ocellated. Body black, with rosy spots behind the eyes and on the sides of the chest, which is also spotted with pale buff; palpi orange, terminal joint black; legs orange, tarsi black; abdomen broken off. The unique specimen of this species collected by Mr. Oates has the abdomen mutilated, but the structure of the fore legs and the shape of the fore wings prove that it is a male individual. 36.
