This is a genus common to Africa and the East Indies, 

 much resembling Deudorix, but with rather long palpi, and two 

 slender tails on the hind wings. The males have frequently a 

 tuft of bristles on the inner-margin of the fore-wings beneath, 

 and a corresponding round patch of scales on the upper side 

 of the hind-wings. The prevailing colours above are blue and 

 black ; beneath they are brown or white, more or less banded 

 towards the hind-margins, and with two black spots, often 

 marked with orange, towards the anal angle. 



The type is
