Imago. —Male. Upperside deep cadmium orange-yellow. Forewmg with a small 
space of the lower base thickly irrorated with greenish-black scales, and a few scales of 
the same colour on the costa, a large pear-shaped black spot closing the end of the cell, 
a broad black exterior marginal border with a sinuous inner margin, slightly running in 
on the lower margin, and curved below the apex where the band is a little broader. 
Hindwing covered with a thin coating of greenish-black scales, except at the end of the 
cell, where there is a large, nearly round, space of the ground colour, and except near the 
inner margin of the outer black border, where there are some spots of the ground colour, 
decreasing in size upwards, the abdominal marginal third very thickly covered with 
some long soft hairs at base, the actual abdominal marginal space whitish, tinged with 
greenish-blue, the marginal black band of medium size, thin near the anal angle, which 
it does not reach, sinuous on its inner margin, thickening at the middle, narrowing at 
the apex and running along the costa to the base, broadening basally and with a large 
white patch close to the base. Underside. Forewing paler than it is above, of a bright 
ochreous-orange tinge, the costal and exterior marginal spaces tinged with green, costal 
line dark orange, two or three small brown spots on it near the apex, three black lower 
discal spots on the inner edge of the outer band, increasing in size hindwards, and 
a large deep black, nearly round, spot centred with white at the end of the cell.
