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

series of black speckles across the middle of the lower half of the fascia, thus forming 
a slightly distinct transverse streak. Hind wing with a somewhat broad black 
marginal maculated band. Underside clear yellow ; a marginal black clot at end of 
the veins. Forewing with a distinct black discocellular spot, an outer transverse 
discal small black-speckled patch at the posterior angle, Hmdwing with a less

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