more pale, and the white spots on it vary in size; the $ has sometimes a fine 

 handsome metallic light blue on the upperside of the primaries near the base. 

 The black dots also on the underside are more pronounced in one individual 

 than in another. But all this applies equally to specimens from W. J., C. J. 

 or E. J. The seasonal differences which Swinhoe accepts, I cannot acknowledge 

 for Java. In fact his illustrations do not at all correspond to my specimens.

Snellen has described this butterfly of which I possess 8 specimens thus. 



This species is distinguished from Puspa by the blue on the upperside of 

 the primaries being of a different shade, without any white middle spot, while 

 the secondaries are paler, and distinctly more darkly veined, the costal margin 

 of the primaries hair fine black and the outer margin black, not narrowing 

 towards the bottom, and distinctly curved towards the base, before which the 

 blue ground colour is somewhat paler. 



The clubs of the antennae are black, on the inner side more or less scaled 

 with light blue. Primaries purple blue, a litde greyish, with a bright satin 

 shine especially at the base and along the costal margin, before the dull black 

 outer margin which is quite 2\ mm. broad it is somewhat paler, cross vein 

 unmarked. The secondaries are somewhat paler, especially beyond the median 

 area, where the blue even becomes whitish. All veins except the cross vein, 

 distinctly darker, the costal margin, above the median cell and vein 6 almost 

 entirely brownish grey, the outer margin also, but somewhat darker, and before 

 it faint dark dots in the cells. The underside is white, a little greyish with 

 a blue tint. The vein system is very delicate dark, the cross vein also. On 

 the primaries the bended-row consists of a series of very fine dark lines, near
