towards the apex but not extended to the terminal margin ; in 

 interspaces 1-4 the apical portion of these streaks is separate and 

 forms a large oval spot ; base of wing and tornal area red, on the 

 former traversed by the black veins, on the latter very variable 

 in extent, more or less formed into rings round the subterminal 

 black spots in interspaces 1 and 2, sometimes in 3 also ; finally a 

 postdiscal shading of blue scales more or less lunular in each 

 interspace. Antenna?, head, thorax and abdomen black; the 

 abdomen brownish beneath. 



tf . Second form = ab. depelchini, Robbe. Upperside: the ad- 

 nervular blue scaled streaks more or less obsolescent, sometimes 

 completely obsolescent on the fore wing, or obsolescent on the 

 fore and strongly marked on the hind wing. Underside: fore 

 wing like that of the typical form ; hind wing with red markings 

 at the tornal angle that extend to interspace 4 ; one or more 

 postdiscal red lunules also in the anterior interspaces. I have 

 seen specimens of this form from Sikhim, Assam and strange to 

 say, from Great Nicobar also. 



(5 . Third form = ab. primigeniiis, fiothsch. " Upperside: hind 

 wing in the anal region with a series of four (Khasia Hills 

 spscimen, type), or two (Sikhim specimen), black spots wholly 

 encircled with almost white scaling ; bluish-grey streaks much 

 whiter than in the usual form of the rf . Underside : hind wing 

 with an anal and three submargiual complete grey rings, the anal 

 ring and a grey subdiscal lunule between the two lower median 

 nervules (veins 2 and 3) tinged with red at their basal sides ; in 

 the Khasia Hill specimen there is a second grey lunule before the 

 middle median nervule (vein 3) and in each of the three anterior 

 cellules stands, close to the white marginal fringe, a grey spot, 

 which is partly joined to a submarginal indistinct lunule so as to 

 form an incomplete submarginal grey ring ; the subdiscal series 

 of blue spots is incomplete ; in the Sikhim specimen these spots 

 are rather well-defined.''' (Rothschild, t. c.) 



$ . First form : tailless. Upperside: fore wing, the basal third 

 of the cell vermilion-red touched outwardly with white, a speck 

 of vermilion-red at base of interspace 2, the basal third of inter- 

 spaces 1 and 2 velvety black, remainder of the wing grey with 

 the veins and medial internervular streaks dusky black. Hind 

 wing : basal half of wing indigo-blue black ; terminal half white, 

 the white traversed by black veins, broadly bordered on each side 

 by black ; terminal margin also somewhat broadly black; inter- 

 spaces 1 to 7 with a series of large velvety-black oblong spots on 

 the white, those in the interspaces 1 to 3 encircled by a diffuse 

 shading of reddish or ochreous scales, those in the anterior 

 interspaces confluent outwardly with the black terminal margin. 

 In some specimens the white does not extend above interspace 5, 

 the basal and anterior portions of the wing are black with a dusting 

 of bluish scales. In others the black terminal margin is very 

 narrow and the subterminal spots distinct from it up to inter- 

 space 6. Underside very similar to the upperside, with similar
