plumbeous frosting. Fore and hind wings : black auti ciliary 

 lines and on the hind wing the black subterminal spot in interspace 2 

 on the underside apparent by transparency. Underside: pur- 

 plish grey. Fore wing: a pair of curved white lines from costa 

 transversely across the cell to vein 1, a short similar line on the 

 inner side of the discocellulars followed by three transverse discal 

 similar lines from costa to vein 1, an inner and outer transverse 

 subterminal series of slender white lunules and an anticiliary dark 

 brown line. Hind wing : crossed transversely by three slender 

 broken lines, with a short line on the inner side of the disco- 

 cellulars between the outer two ; these are followed by a discal 

 and a postdiscal less broken and interruped similar lines, a double 

 series of slender white lunules and a dark anticiliary line as on 

 the fore wing. Cilia of both fore and hind wings dark brown. 

 Antennae black, the shafts obscurely speckled with white ; head, 

 thorax and abdomen brown, thorax and abdomen slightly purplish ; 

 beneath : palpi white fringed with long black stiff hairs, thorax 

 and abdomen purplish grey. . Upperside : fuscous brown, the 

 veins prominent ; an elongate oval medial patch extended from 

 base outwards on fore wing for about two-thirds of its length, 

 dull brownish-white brilliantly iridescent with metallic blue in 

 certain lights. Hind wing : a postdiscal transverse series of 

 slender detached white lunules, followed by a similar subterminal 

 series of continuous lunules that encloses between it and a slender 

 terminal white line a transverse series of black spots ; these spots 

 decrease in size anteriorly ; lastly a conspicuous anticiliary black 

 line. Underside : pale ochraceous-brown ; markings much as in 

 the c? , but of the transverse white lines that cross the disc of the 

 fore wing the outer one is shorter, not extended below vein 3. 

 Antennae, head, thorax and abdomen as in the tf , but the head, 

 thorax and abdomen paler with no purple gloss.

Race nicobarica, Wood-Mason & de N. <3 Upperside : ground- 

 colour darker, plumbeous effulgence more striking. Underside: 

 very dark purplish-brown ; markings in form and arrangement 

 much as in the $ of the typical form, but the transverse bands 

 formed by the white lines much broader ; on the hind wing the 

 black subterminal spots in interspaces 1 and 2 much larger, con- 

 spicuously crowned inwardly and surrounded with ochraceous 

 orange and with an outer bordering of metallic green scales ; the 

 anticiliary black line edged inwardly over the tornal area with 

 white. Antennae, head, thorax and abdomen as in the typical 

 form. $ . Closely resembles the typical form, but differs as 

 follows: Upperside: fuscous black, the ground-colour much 

 darker than in the typical form ; the pale medial patch on the 

 fore wing shot in certain lights with iridescent blue, much larger,
