The species with which we are acquainted may be distinguished as follows : — 



1 (10). Hind winCT below with no pale spot near the middle of cell 8. 



2 (9). Pale markings on tbe bind wing below uon-metallic. 



3 (6). Fore wing above blackish brown with yellow spots. 



4 (5). Hind wing below with a subterminal series of pale spots. Hind 



tibiae with one pair of spurs palamon, Pall. 



5 (4). No subterminal series of pale spots on hind wing below. Hind 



tibise witli two pairs of spurs abaa;, Ob. 



6 (3). Fore wing above yellow with black spots.

sided within, bounded inwardly by that vein houangty, Ob. 



9 (2). Pale markings on the hind wing below metallic silvery white, and 



consisting of the following : — A streak along the upper edge of 

 the cell from the base as far as the middle of cell 5, constricted 

 or narrowly interrupted at its lialf-length, the lower edge of its 

 outer half coalescing with a somewhat semi-circular spot in cell 4, 

 a spot occupying the apical third of cell 6, a roundish spot near 

 the base of cell 2, a clavate streak from the base to the middle 

 of cell 1 b, and a submarginal series of oblong spots, placed one 

 in each of cells 1 c, 2, and 3, sometimes feebly continued in 

 cells 4 and 5 pulchra, Leech.

 and downwards by way of the transverse vein ; a small pale spot 

 near the basal third of the cell, and the indication of another
