wing, where it is much narrowed, especially in the spaces between the 
anal vein and the first and second branches of the median vein, extend- 
ing considerably more forward between the second and third branches 
of the latter, so as nearly to unite with the truncated extremity of the 
large brown patch ; the brown apex of the wing bears a row of five 
fulvous oval spots, the hind one of which is ill defined and less strongly 
coloured : the hind wings are brown at the base, and beyond the 
middle they are marked with a curved irregular brown bar, which 
is partially connected with the brown spotted hind margin of the 
wing, having a row of white spots between them, which become larger 
and more or less confluent, especially towards the anal angle. On the 
under side the fore wings are tinged with yellow, especially towards 
the tips, the large brown markings of the upper side being nearly 
obsolete : the hind wings are also yellowish, with a faint dusky 
fascia beyond the middle, with a black discoidal spot surmounted 
with yellow scales ; the costa at the base is bright yellow, and the 
fringe of all the wings is white. The female is slightly larger, with 
the brown markings more suffused, the orange spots of the fore wings 
obsolete, and replaced by brown, and the white submarginal spots 
of the hind wings almost obliterated and replaced with brown.
