Description of adults: (Bingham 1907): Wing expanse: 90 - 127 mm. ". Upperside black, densely irrorated with green scales. Forewing: an outwardly oblique, slightly concave subbasal band and a narrow terminal edging jet-black due to the ground-colour there being devoid of the green scaling; beyond the subbasal band the irroration of scales is a much brighter green, especially along the outer edge of the subbasal band itself; but along obscure, broad, convergent discal and postdiscal transverse bands and along a subterminal much narrower band, the green scaling thins out and the black ground-colour of the wing shows through; in some specimens, owing to the transparency of the wings, the rich ochraceous-brown colour of the underside gives the black on these bands a reddish tint. Hind wing: basal area margined outwardly by a narrow irregularly sinuous band devoid of green scaling, succeeded by an upper discal bright chrome-yellow patch that spreads from base of interspace 3 across the apex of the cell and bases of interspaces 4 and 5 to the costa; this patch is bluntly angulated outwards in interspace 5, stained with orange anteriorly and bordered outwardly by black which is widest above; below the patch a white line extends to the dorsum ; the postdiscal area is deep dark green, margined inwardly by diffuse dark grey and followed outwardly by a subterminal series of lunular markings, the tornal and upper two or three of which are yellow, the rest bright green; tail tipped with yellow. Underside: basal area of both fore and hind wing densely covered with green scales. Fore wing: terminal two-thirds rich ochraceous brown, the green of the basal area bordered by black; discal and postdiscal bands also black, widened and diffusely coalescent posteriorly; an incomplete, very slender subterminal black line and broader black terminal edging, neither of which reaches to the apex. Hind wing much as on the upperside, but the yellow markings broader. Antennae dark red; head, thorax and abdomen black, covered somewhat densely with green hairs and scales. - much larger, differs also in coloration and markings as follows: Upperside, forewing: the irroration of green scales on the terminal two-thirds restricted to a subterminal moderately broad band diffuse along its inner edge, and a medial somewhat ill-defined similar band that is bordered both on the inner and outer sides by diffuse dusky black; this is succeeded by two broad diffuse transverse dark grey bands, the outer of the two edged on its outer side narrowly with black, followed by a subterminal green band and terminal velvety-black margin. Hind wing: the upper discal yellow patch so conspicuous in the , replaced by a very much larger dark grey patch, below which comparatively narrow markings of yellow extend up to the dorsum; a postdiscal sinuous lunular narrow black band and a subterminal series of green lunules as in the , but the apical lunule dark grey, not yellow; the tail-like extensions of the termen at the apices of veins 3 to 6 are black shaded with green, those at the apices of veins 4 and 6 tipped, the former with yellow the latter with greenishwhite. Underside similar to the underside in the , but on both fore and hind wing the areas coloured with rich ochraceous and yellow are grey, with the exception of a well-marked moderately broad subterminal band on the fore wing which is of a dull ochraceous colour; on the hind wing the grey discal area extends right up to the apical lunule of the subterminal series. Antennae, head, thorax and abdomen as in the ."

Distribution:

The typical subspecies of T. imperialis is distributed along the southern slopes of the Himalayan mountains in north-eastern India (e.g. Manypur, Assam, Sikkim), Bangladesh, Nepal and Bhutan (?).
