POEITIA. 461 



on the apical portion of the wing may, as in the d" , be present or 

 absent. Hind wing : the blue pear-shaped area on the posterior 

 half of the wing reduced to short outwardly broadened streaks, 

 which are further more or less irregularly interrupted by a trans- 

 verse patch of the ground-colour ; beyond the streaks there is a 

 somewhat ill-defined posterior postdiscal series of black spots, darker 

 than the ground-colour, bordered inwardly by a series of blue 

 lunules and outwardly by a series of linear, more slender, bluish- 

 white lunules, followed by a continuous slender terminal yellow 

 line outwardly margined by black. Cilia of both fore and hind 

 wings dark brownish black alternated with white. Underside : 

 similar to that of the c? but the transverse /igzag loops and 

 broken lines not so clearly defined nor so numerous, broader, more 

 diffuse, often coalescing one with the other. 



Exp. 3 $ 35-40 mm. (1-4-1 -54"). 



Hob. Himalayas, at comparatively low elevations, from Kumaon 

 to Sikhim and Bhutan ; Assam ; Chittagong and Arracan hill- 

 tracts ; the hills of Burma and Tenasserim. 



A very variable form both in ground-colour and markings, 

 especially on the underside.

<$ . Upperside : velvety black. Fore wing : the interspaces poste- 

 rior to the cell overlaid with rich dark antwerp-blue from their bases 

 outwards as follows : interspace 1 a for four-fifths of its length, 

 interspace 1 for a short distance further but still leaving a terminal 

 margin of the ground-colour which also indents the apex of the 

 blue colour in that interspace, interspace 2 for half, 3 for one-third 

 of their lengths ; in some specimens in interspace 1 there is a short 

 outwardly directed black streak in the middle of the blue area ; 

 interspaces 2 and 3 have detached subterminal blue spots ; cell at 

 base overlaid with blue, the upper edge of which is continued along 

 the subcostal vein for a short distance ; beyond apex of cell there 

 is an obliquely-placed preapical series of blue streaks in interspaces 

 5, 6, 7 and 10 ; those in interspaces 5 and 6 the longest ; some- 

 times the blue in these is interrupted which gives an appearance 

 of a streak with a detached spot beyond in each. Hind wing : 

 posterior half, except the abdominal fold, from base almost to the 

 termen overlaid with rich antwerp-blue ; this area bears near 

 the termen a series of three transverse linear, black spots ; costal 

 margin broadly and abdominal fold fuscous, paler than the black of 

 the ground-colour ; within the cell touching the subcostal vein is 

 a comparatively large oval yellowish area which bears an anteriorly 

 directed tuft of long soft brown hairs (the secondary sex-mark) ; 

 lastly, an anticiliary jet-black line most prominent opposite the 

 apical end of the blue area. Cilia of both fore and hind wings 

 brown, on the latter wing with a more or less interrupted line of 

 white along their bases. Underside : ground-colour and markings
