cJ . Upperside : velvety black. Fore wing : posterior half from 

 base outwards and a broad streak that fills the basal three-fourths 

 of the cell brilliant blue, in certain lights rich metallic green ; the 

 outer portion of the blue streak in cell narrowly separated from 

 the blue below the median vein by a short streak of the ground- 

 colour ; the blue area on the posterior half of the wing fills the 

 whole of interspaces 1 a, 1 and basal three-fourths of 2 except a 

 narrow terminal edging of the ground-colour ; the blue is also inter- 

 rupted by a short, very narrow streak of black along the middle 

 of vein 1 and another similar but much shorter line along middle 

 of vein 2. Hind wing : the ground-colour broadly along the costal, 

 more narrowly along the dorsal margin, paling to dull brown ; 

 secondary sex-mark of a tuft of anteriorly directed hairs brown, 

 placed on an oval yellowish patch ; posterior portion of the wing 

 brilliant blue with the same changeable sheen as on the fore wing ; 

 this colour widening outwards from a comparatively narrow streak 

 at base till on the termen it extends from vein 1 to vein 5 ; inter- 

 rupted only by an ill-defined, incomplete, subterminal series of 

 narrow transverse spots of the ground-colour. Cilia of both fore 

 and hind wings black. Underside: very pale silvery -grey with 

 numerous markings of rusty-brown as follows : Fore wing : cell 

 crossed by four or five short catenulated bars that do not extend 

 below the median vein ; a transverse very irregular narrow band 

 along the discocellulars continued to vein 1, this is widened and 

 forms a sort of double streak between veins 2 and 4 ; beyond 

 there is a discal sinuate irregular catenulated band each link of 

 which is inwardly conical, a similar postdiscal band each link 

 of which is ontwardly conical, and between the latter and the 

 termen a series of more or less diamond-shaped spots of the 

 ground-colour within each of which are some ill-defined brown 

 markings and in the posterior spot of all a black smaller spot 

 inwardly crowned with ochraceous. Hind wing : crossed by five 

 or six catenulated transverse bands similar to those on the fore 

 wing but all more or less sinuate, broken and interrupted; beyond 

 these an inner, subterminal, irregular, transverse zigzag band 

 ending in a small black spot near the tornus which is broadly edged 

 on the inner side with ochraceous yellow, an outer subterminal series 

 of large, very irregular, inwardly pointed spots and a slender 

 articiliary black line. Antenna?, head, thorax and abdomen 

 black, the antennae ochraceous at apex, the thorax with a few 

 bluish hairs ; beneath : the palpi, thorax and abdomen white. 

 5 . Upperside : dark brownish-black. Fore wing : blue markings 

 somewhat as in the tf but the blue is very pale, not at all brilliant,
