 inner margin of the posterior wing. Posterior wing with two black eyes, with an 

 indistinct rufous iris, one near the apex, the other at a short distance from the 

 anal angle. 



Underside. Anterior wing with the base to the end of the cell (upon which 

 there are two black spots), and a spot on the middle of the costal margin white ; 

 the rest very light brown crossed beyond the cell by an irregular broad band of 

 darker brown bordered with black, followed first by a zigzag band of black, and 

 afterwards by a line of cordate spots, some of which are united with the line above 

 them. Posterior wing from the base to the middle white, the nervures upon it 

 and several curved lines black, followed by a broad band of red-brown beautifully

On the upperside this species differs much from all the other blue or green-banded Preponas. 

 It, is, too, without the blue spots near the costal margin. The blue baud is nearer to the base, much 

 narrower, and of a very different colour. On the underside it is a good deal like I'. Demodice of 

 Boisduval (Species Gen. Lep. PI. 7).
