the middle crossed by the black veins, a subterminal row 

 of whitish dots in the broad black terminal border, and 

 a white lunule in the middle of the border near the edge 

 of the wing. In the female there are traces of other 

 white lunules just within the margin. The hind wings 

 are similarly marked, except that there is a row of black 

 submarginal spots circled with fulvous, and the lunules 

 are faint in the males. 



Under side of fore wings fulvous, marked about the 

 same as in P. Nycteis, except that there is more black 

 through the middle. The terminal border is as above, 

 save the terminal lunules. Between median venules one 

 and two there is a large conical whitish spot, the base on 

 the double terminal line; this double line running in 

 zigzag to the apex, the inner points silvered more broadly 

 towards the apex, and the inner point sending a white ray 

 to the margin. The same is repeated towards the pos- 

 terior angle, but with less silver. 



The hind wings dark brown washed with whitish, 

 more towards the base, only two yellowish spots in the 

 cell. Near the base is a broken silvery band, and through 

 the middle a silver band crossed by the brown veins, 

 the outer margin dentate. The submarginal row of black 

 spots as above, only they are pupilled with white and not 

 circled with fulvous. The margin is similar to that of 

 the fore wings, save that the large spot is silvery instead 

 of whitish.
