as costa ; club slender ; apiculus acute. Palpi appressed, third joint almost concealed. 

 Fore wing : dorsum longer than the termen, vein 5 nearer 4 than 6 ; first and second 

 median segments subequal in length, the third about two-thirds as long as the second, 

 vein 12 feebly sinuate towards vein 11. Hind wing : first median segment about 

 three times as long as the second, the third about one-fourth as long as the second. 

 The species known to us may be distinguished as follows : — 



1 (6). Fore wing above with a red-yellow or yellow band. 



2 (5) . Pale band on fore wing above red-yellow, passing obliquely from the 



middle of the costa to the tornus. 1 



3 (4) . Male with a black patch of androconia near the base of the hind wing 



above, coinciding with the cell. Expanse 50 mm armata, Druce. 



4 (3) . No sex-mark on hind wing above in the male. Hind wing above 



with a small spot of pale purple scales in each of cells 2, 3, 5, and 6. 



Expanse 32-34 mm gemmifer, Butl. 



5 (2) . Pale band on fore wing above yellow, very broad, passing from the 



dorsum towards the middle of the costa, where it is cut short by 

 the upper edge of the cell, its outer edge convex, its inner edge 

 passing obliquely from the apex towards the base and giving off 

 along the dorsum a triangular tooth to the base of the wing . . fulgur, de NieeV. 



6 (1). Entirely fuliginous or olive-brown above diodes, Moore.
