Description
- See glossary for terms used
Variable in the extent and breadth of the orange-yellow markings and in the mottling and ground-colour of the underside. Typically males and females have the groundcolour on the upperside dark brown, with the following orange-yellow markings :— Fore wing: a streak from base along the median vein extending narrowly on each side of it and continued beyond as a comparatively large oval spot in base of interspace 2; two preapical double spots placed obliquely to the costa. Hind wing uniform, with a slightly oblique narrow medial band extending from vein 1 to vein 5. Underside fore wing : ground-colour brown; orange-yellow markings as on the upperside, but broader, more diffuse; apex and dorsal margin broadly shaded with pale grey irrorated with minute dark spots and transverse short striae. Hind wing greyish brown irrorated with minute dark spots and short transverse striae, and shaded in the cell, on the middle of the costal margin, and on the middle of the termen with diffuse brown. Antennae, head, thorax and abdomen dark brown ; beneath, palpi, thorax and abdomen greyish brown.[1]
The larger varieties, with very broad orange markings on both fore and hind wings, have been separated as race sanguinalis. This is chiefly a Himalayan and Eastern form. Variety rama Moore is the smaller Southern and Ceylon form, with the orange markings much narrower and restricted and the preapical double spots entirely white, or white slightly suffused with yellow. Every gradation between the two forms, however, can be found. Many specimens are identical with typical forms from Java.
Wing expanse of 46–58 mm. Found along the Himalayas, from Kulu to Sikkim; the Western Ghats and southern India; Sri Lanka; Assam; Myanmar; Tenasserim ; the Malayan Peninsula ; China.
