cJ. Differs from the western form in the halfmoon-shaped pale marginal space 

 of the forewing being more shar])Iy defined, pure in colour, with the veins in it not 

 streaked with brown, and in U^ of the forewing being less than one-third the 

 length of D*, the cell being narrower than in taedinm taedinm.

c?. Body and wings, above, much darker than in gorgon and taedinm, chocolate 

 mummy-brown, almost black in some places. Dorso-lateral patches of wool on 

 abdomen large, directed upwards and backwards, sixth tergite with greyish white 



fringe. Forewing, uiiper.Hide : apex truncate, not sinuate ; basal two-thirds 



flushed with grey, exce])t a large space between M- and R^ and the costal margin, 

 which are chocolate-black, tiie greyish area forming a curved band from costal margin 

 to hinder margin at angle ; posterior veins within this band with interrnpted bluish 

 white streaks, jKistcrior j)art of grey area crossed by dark undulating lines running 

 from black jnitcli backwards, (tostal margin with thin bluish white lines ]iroximally 

 of apex of cell ; outer third of wing like discal pfitch, excepting a sharply defined 

 marginal halfmoon from SC' beyond M', which is clayish ; SC^ and R' with 

 interrupted bluish white streaks, liluish wliite scales also at costal margin ; an 

 ovate subbasal cavity behind M, deep, clothed with dispersed narrow and long 



Bcales ; fold as narrow as in taedium. Hindwing dark mummy-brown, apex 



down to M' and costal area paler ; snbmarginal dark line rather more distal than 

 in the allied sjiecies, outer margin less convex. 



I'lidentidr : barely darker than in gorgon. Cell of forewing narrower than 

 in gorgon and taedinm, D^ very short, curved, D'' longitudinal, not obliciue or 

 transverse ; R' curved, R' also a little.
