 spots on the hind marginal border extending to the submedian 

 nervure. The base of the hind wing is deep brown. 



The fore wing has a moderately large yellowish spot in 

 the middle of the discoidal cell, with a second larger oval 

 spot between the first and second median nervules. 



Between the radial or discoidal nervules there are two 

 medium-sized yellowish spots near the apical portion. At 

 the apex of the fore wing there is a row of small white spots 

 extending to the hind margin, Avitli four smaller white spots 

 outside the first row of spots, placed about the middle of the
