outwardly curved ; costa much arched at base, then nearly straight to the apex in 



the male, slightly arched in the female, outer margin convex to the tail, deeply 



excavated from the tail to the anal lobe in the male, a somewhat short tail at the 



end of vein 2 ; in the female there is a second tail of equal 



length at the end of vein 3 ; both sexes with a large anal 



lobe, abdominal mai'gin excavated above the anal lobe, then 



convex to the base of the wing. Palpi long and slender, 



legs short. Antennae uniformly thickened, no secondary sexual 



characters. 



Genitalia, of the usual Lycsena shape, the tegumen being 

 less ample, the hooks, however, are short and stout, whilst the 

 clasps are not so reduced as in the genus Arhopala ; the penis 

 is long and slender, with the extremity slightly extended.

 a small ringlet at the end, sometimes round, sometimes elongated, two dots near the 

 costa above it, a sinuous, recurved, thin discal line, and a sub-marginal series of dots.
