As shown in the accompanying illustration the colour of Java individuals of 

 this species is considerably darker on either side than that represented in the 

 figures of Moore and Fruhstorfer. 



The species, although a mountain butterfly, occurs lower, as appears from 

 the above records, than Fruhstorfer thinks, for he states that it is never met 

 with below 1200 metres altitude. I can see no difference between specimens 

 from West and East Java, although Fruhstorfer distinguishes a dry season 

 E. J. form which he calls Mangala.
