gin, which forms on the inner side a triangular point 
in the centre of each are.olet, and encloses a row of 
pretty large round spots, corresponding to the ground 
colour of the surface. The primary wings are ra- 
ther bright yellow beneath, the black spots smaller 
than the corresponding ones on the surface, and the 
tip spotted with light yellow. The hinder wings 
bear several large yellowish-white spots at the base, 
some of them slightly glossed with silver, the spaces 
between being rust-red ; the latter colour forms a 
large spot in the middle, ornamented with a central 
ocellus. Beyond this, there is a long quadrate sil-

is adorned with a row of large triangular silvery 
spots, bounded on all sides by a deep black line. 
The fringe of the wings is yellowish, spotted with 
brown ; the antenna? rinsed with white, and the 
knob tipped widi reddish-brown. Several varieties
