Range It is found in the Naga Hills in India, Myanmar, Malaya, Sumatra and the Philippines. Status The species is considered very rare. Description A small butterfly, 40 to 50 mm in wingspan, it is the largest of the genus. The upper forewing in both sexes has a broad white discal band which extends right up to dorsum, the upper edge of which is sharply angled at vein 3. The upper hindwing has a pale discal streak. Technical description The male has the upperside of wings dusky brownish black. The ground colour of the forewings darker, almost pure black in fresh specimens, on the apical third of the wing; a short streak in the middle of interspace 1, a more outwardly produced similar streak in interspace 2, basal halves of interspaces 3 and 4, the lower apex of the discoidal cell and the extreme base of interspace 5, white, all forming a median conspicuous irregular white patch on the wing, narrowly traversed by the veins which are greyish brown. Hindwing: more uniform, slightly darker on its anterior half. Underside: light brown with an ochraceous tint. Forewing: the median white patch as on the upperside but larger, its margins less clearly defined, continued posteriorly to the dorsal margin; obscure catenulated (in the form of a chain), incomplete, transverse, white-margined narrow bands, two at base and two or three very short ones above the white median patch on the costal area, from between the outer two of these latter a transverse, zigzag, very slender, somewhat obscure white line crosses the anterior portion of the wing to vein 4; lastly a pre-tornal quadrate brown spot near apex of interspace 1a and an obscure sub-terminal transverse series of slightly lunular small brown spots; the ground colour terminally paler and more ochraceous than on the inner portions of the wing. Hindwing: crossed by very obscure sinuous brown and white slender lines, that on the costal area form very short, obsolescent, catenulated narrow brown bands; a subterminal series of brown slender lunules, sometimes obsolete. Antennae, head, thorax and abdomen brown; beneath: paler, the palpi and thorax more or less white. The female has the upperside forewings of dark brown; base shaded with greyish brown; the white
