Only two undoubted species of this genus are known; they may be separated as 
follows :— 
Supplementary sector next below the subnodal sector forming a loop with the latter 
and enclosing 5-7 cells on the front, 6-7 cells on the hind wings ; front wings 
with 7-8 postnodals in the first series, 5-6 in the second series; hind wings 
with a basal brown area, veined with yellow, stopping at the distal subbasal 
sector (A, of C. & N.) or, in a few females, reaching to the triangle; frons 
superiorly and the vertex metallic-violet (¢), which is much reduced in the 
female, where it occupies only the base of the vertex and the postero-superior 
surface of the frons; male with the lower edge of the superior abdominal 
appendages beginning to taper to the apex at 3-3 their length, inferior appendage
