Wet-season Brood (Plate 542, fig. 1, la <$, lb, c $ ). 
Male. Upperside greyish-white. Forewing with the costal border sprinkled 
with grey scales; a prominent black exterior marginal decreasing dentated band, the 
black extending along the subcostals, radials, and upper and middle medians, on 
each of which it dilates, and thus forms a more or less incomplete excurved subapical 
fascia enclosing the apical white elongated streaks. Tlinclwing with a prominent 
black exterior marginal dentated band, the inner points of which are each prolonged 
acutely for some distance along the veins ; the subcostal and medial fascia of the 
underside being slightly visible. Underside greyish-white. Forewing with similar 
but much less prominent marginal band, the vein portions being more narrowly lined. 
Hindwing with all the veins—except the base of the median, upper discocellular, and 
base of radial, and entire lower submedian—distinctly black lined, each vein also 
being slightly edged on both sides with blackish scales, these scales being more 
broadly sprinkled along the subcostal from its base to apex ; a black scaled speckled- 
fascia also extends across the middle of the wing from lower subcostal to the 
submedian vein. 
Female. Upperside fuliginous greyish-black. Forewing with a sullied or 
greyish-white broad subapical oblique patch, a discal patch extending pointedly 
inward below the cell towards the base, sinuously outwards to posterior angle and 
then for some distance below the submedian ; also four or five apical more or less 
distinct white small narrow ovate spots. Hindwing with a white upper-discal broad 
patch extending from the subcostal across outer half of the cell, and a lower-discal 
series of spots increasing in size posteriorly and obsolescent anally. Underside with 
similar but much less-defined markings as on upperside. Forewing with the dark 
portions much paler, being either fuliginous or dark fuliginous-grey, the apical area 
more or less olivescent-yellow tinged, and the spots more or less obsolescent, the 
cell-area also either dark grey or olivescent tinted. Hindwing with the dark portions, 
as on upperside, much less defined, and of a more or less olivescent-yellow tint, the 
base of the costa being bright yellow. 
Expanse, S $ 2 x - 0 to 2^ inches. 
Intermediate Form (Plate 542, fig. Id, e <y, If $ ). 
Apjjias Olferna, Swinhoe, Ann. Hat. Hist. 1890, p. 358, <$ 9 . 
Male. Upperside. Forewing with similar but somewhat narrower, and much 
paler defined outer marginal markings than in the wet-form. Hindicing also with 
very slightly-defined or obsolescent outer-marginal vein-points. Underside. Fore- 
icing white, the apical area very faintly flushed with pale yellow ; marginal markings 
either obsolescent or obsolete. Hindwing almost white or very faintly flushed with
