Wet-season Brood (Plate 542, fig. 2 £, 2a, b $ ). 
Imago. Male. Upperside greyish-white. Foreiving with black costal edge, and 
grey-black scaled irrorated basal costal border; a black-scaled very narrow exterior 
marginal dentated band decreasing from the subcostal to the submedian. Hindwing 
with very small indistinct blackish-scaled, marginal vein-points, which are obsolete in 
some specimens that probably emerged near the dry season. Underside white. 
Forewing with the costal and outer edge slightly blackish; a few greyisli-black 
scales along the base of costa. Hindwing unmarked. 
Female. Upperside greyish-white. Foreiving with greyish-black costal edge, a, 
broad longitudinal band from base of the costa and filling up the cell—with the 
exception of a thin streak above the median vein, this black cell-band more or less 
thinly extends along the upper median veinlet and joins a broad outer-marginal 
decreasing band extending sinuously from before the apex to posterior angle, 
enclosing the white subapical oblique quadrate patch, the outer band showing faint 
traces of paler intervening streaks ; a less intense greyish-black fascia extends 
pointedly outward from below the cell to the disc in extreme wet-season specimens. 
Hindiving with a greyish-black marginal macular band composed of large confluent 
spots, or, of more or less slightly separated spots paling diffusedly to the anal angle, 
and connected by similar coloured scales along the veins from the lower subcostal to 
a discal curved paler fascia, which latter becomes obsolete posteriorly. Underside 
white. Both wings with dark-grey similar disposed markings. Foreiving with the 
outer band traversed by white interspaced streaks, or this band is white and its 
inner edge only defined by dark grey. Hind wing with the outer-marginal macular 
band indistinct or obsolescent; base of costa pale yellow. Some intermediate 
specimens of this sex (Plate 542, fig. 2a)—which agree with the Fabrician type 
specimens of Libythea —emerged probably near the dry season, vary on the upperside, 
in the forewing, in the connecting black streak along the upper-median to the outer 
band, and also the lower basal fascia, being either obsolescent or obsolete, and in the 
hindiving, the marginal spots are smaller and more or less well separated, the discal 
fascia with its connecting veins is also obsolescent or more generally entirely absent. 
On the underside, the markings are much less defined ; on the forewing the outer band 
is very faintly indicated by the greyish inner-edge, the apical area being entirely 
white or very faintly tinged with pale yellow, and on the hindwing the ground-colour 
is either white or very faintly tinged with pale yellow, the discal fascia being faintly 
indicated, and the marginal spots absent. 
Expanse, d ? 2 to 2f 0 inches.
