Imago. —Male. Upperside bright pale blue. Forewing much as in Pingasa , the 
median and lower vein as broadly black-striped as the same form of that species, the 
outer marginal band not nearly so broad, but fairly uniform in width hindwards, and 
generally containing a row of small blue streaks, the apical and medial streaks the 
largest. Hinclwing with the exterior band broader than in the fovewing and very 
uniform, the veins about as broadly black as in Pingasa , the usual white costal space 
with blue at its base, the next one below it tipped with white, the androconia scales 
covering the entire outer band. Underside bright pale bluish, of a different tint to any 
of the preceding species, the sub-costal and median veins rather broadly black, as also 
veins 1, 2 and 3, all three ending with large black sub-marginal patches, outer band 
space darker than the rest of the wing enclosing a series of large pale spots. Hindwing 
almost clear, the upper vein markings showing slightly through the wing, and near the 
outer margin is a series of pale greyish lunules. 
Female. Upperside dark blackish-brown, the sub-marginal spots smaller than 
usual, and all the streaks in the interspaces on both wings thin, of a greyish-white 
colour and more or less faintly indicated. Underside of a uniform dull pale blackish- 
brown colour, the spots larger, the streaks broader and rather more clearly indicated 
than they are above.

Dry-season Brood (Figs. Id, le, 9> If, lg, 9). 
Male. Similar to the other form, on the uppersides the veins are much less 
heavily marked, and the outer band is much narrower and tapers somewhat hindwards 
on the forewing, on the underside it is duller in colour, the forewing has normal vein 
markings, and the patches at the ends of the veins 2, 3 and 4 are small. Hindwing 
without markings. 
Female. Upperside with the stripes much broader and the spots larger. Under¬ 
side whitish faintly tinged with blue, the stripes on both wings very broad, the inner
