Palpi white : face opalescent or silvery, according to the light : antennæ maroon-brown, silvery towards the apex: tuft maroon-brown : thorax of a shining metallic lustre, in some lights opalescent : a streak of the same hue crosses the extreme base of the wings, is continued for a short distance along the dorsal margin, and thence curves obliquely across the wing again to the costal margin, enclosing a maroon-brown patch upon the costa, and being narrowly margined behind with dark maroon, beyond which the wing is bright golden to the apex.
