This species can be recognised from any of its neighbours by the very pale lilac of 

 its upperside, and by the pale grey of its underside with decided black spots encircled 

 distinctly with whitish. It is a beautiful and very distinct species and is not very 

 closely related to any, but is probably best placed here ; de Niceville says (I. c), 

 "Occurs in Sikkim tarai (not in the hills) in July and August ; it is also found at 

 Jalpaiguri and eastwards throughout Assam, and the late Mr. H. M. Parish obtained it 

 in July in the Chittagong Hill tracts. It appears to be confined to the lower hills and 

 the country at their feet."

d . Upperside : both wings pale lilac-blue, with fine black costal and posterior 

 margins ; in the secondaries the dark costa is rather broad. Abdominal fold pale 

 greyish. Tail black, tipped with white. Underside : both wings darkish brown, spots 

 precisely the same colour as ground, but broadly margined with whitish. In the 

 primaries the space below the lower median nervule is pale greyish. Primaries with 

 three discal spots increasing in size; above the second are two very small confluent 

 spots and one small one above the very irregular and large spot closing the cell, 

 while touching it beneath is a large one; the spot below the discoidal cell is large 

 and distinct. The transverse band consists of four distinct spots — the first on the 

 very close to the terminal discal spot, the other three shifted outwards and 

 outwardly inclined, below which are two large spots shifted much inwards but with an 

 outward inclination ; immediately below these is a very small detached dot ; the sub- 

 marginal row of somewhat quadrangular spots distinct, extreme margin whitish. 

 Secondaries with lour largish basal spots below each other, the fourth shifted inwards, 

 followed by three longer ones ; cell closed by a large spot, below which and touching it 

 is another shifted a little inwards ; the transverse chain-like fascia is composed of four 

 pairs of spots, the upper of the costal two touching the upper one of the three larger
