This species is closely allied to the preceding one, of which it 

 may be a local form, but difters in outline, the costae of the hind 

 wings being more direct, the lower portion of the outer margins 

 of the fore wings not convex as in Pythia ; in colouring it differs as 

 follows : — hind wings above entirely blue, with only a very indistinct 

 violaceous oval spot, and two dots near the anal angle, below with 

 a discoidal streak within the hind-wing»cell.
