d. Upperside: both wings rather intense deep blue: primaries with the costa 

 broadly, posterior margin more broadly, apex still more broadly black ; secondaries 

 with the blue limited to just over the median area, the rest of the wings black. Tails 

 two, black, the longer one white-tipped. Underside : both wings very dark greyish 

 brown : primaries with an obscure dark dot near the centre of the cell and a small 

 dash closing it, costa with three dark dots; transverse blackish line curved irregularly 

 and scalloped from the costa to the submedian nervure, a submarginal row of blackish 

 dots, margin obscurely dark, internal area quite pale: secondaries with a small white 

 spot about one-third along the costal nervure, below which is an obscure dark short dash 

 in the cell ; from two-thirds along the costa to the middle of the abdominal margin is 

 a narrow, indefinite, obscure band of dark shading edged externally and sharply with 

 white, a submarginal row of dark spots forming an almost lunular line; on each side 

 of the long tail is a slight grey scaling. 



2. Upperside: both wings entirely dark brown. Underside as in the male, but 

 decidedly paler. 



In this species the outer margin is much produced in the median area, both in the 

 male as well as in the female, but is a somewhat unusual feature in the former, whilst 

 in the female the tip is much less produced outwards, forming less of a hook-tip.

d . Upperside : both wings dull violet to purplish blue : primaries with apical area 

 very broadly dark brown, tapering very narrowly to the anal angle and less narrowly 

 on the costa : secondaries with blue confined within the upper discoidal and 

 submedian nervures; posterior margin narrowly brown. Underside: both wings 

 warm slightly rufous brown. Primaries with the least trace of a most obscure spot
