Wet-season Brood (Plate 580, figs. 1, la, ^ ?). 



]Male. Uppersicle pale olivescent-yellow, the base obscured by dusky-grey scales. 

 Forewing with the orange sub-apical fascia somewhat narrower than in /. frequens, its 

 upper discocellular portion larger and prominent, its inner black border broad, llind- 

 wliiy with a broad black marginal band, which is more or less macularly continuous, 

 or slightly broken and macular. Underside pale yellow. Both wings with a very 

 slightly-defined small discocellular spot, and two medial-discal obscure pale orange 

 spots on the hindwiiig. 



Female. Upperside white, the base obscured by dusky-grey scales. Forewing 

 with the apical half black, its inner border broad, the sub-apical fascia white, and 

 crossed by two lower black spots. liindwing with a moderately broad black marginal 

 irregular-edged band. Underside white with a few apically-disposed slightly-defined 

 dusky slender strigte, a blackish discocellular spot, lower discal spots, and an elongated 

 patch from the posterior angle. Hindwivg with slightly-defined outwardly-disposed 

 slender dusky discal strigse, a small discocellular spot, two somewhat angled medial- 

 discal spots, and a similar costal spot. 



Expanse, $ 2^ to 2|, $ 2 inches. 



Intermediate Form (Plate 580, fig. lb, $). 



Male. Upperside pale yellow, tinged with green at l)ase and on the costa. 

 Forewing with a broad black apical area occupying more than an oblique half of the 

 wing, and enclosing a sub-apical narrow curved orange-red fascia crossed by black 

 veins, the lower veins being broadly black speckled along their edges, and a transverse 

 series of black speckles across the middle of the lower half of the fascia, thus forming 

 a slightly distinct transverse streak. Hindwing with a somewhat broad black 

 marginal maculated band. Underside clear yellow ; a marginal black dot at end of 

 the veins. Foreunng with a distinct black discocellular spot, an outer transverse 

 discal small black-speckled patch at the posterior angle. Hindwing with a less 

 apparent discocellular spot, and a transverse discal series of yellowish-brown spots, 

 the anterior being most prominent. 



Expanse, $ 2^ inches. 



Dry-season Brood (Plate 580, figs. Ic, id, $ ?). 

 Male. Upperside similar to Wet form. Underside also similar to JVet form, 

 except that the forewing has a small blackish patch at the posterior angle, and on the 

 hindwing there is a transverse series of discal dusky-speckled white-centred spots.
