Near I.fausta. 



Male. — Upper wings with the outer margin more convex, the 

 apex blacker, leaving a row of small spots, the discoidal spot very 

 large and nearly round ; thorax and abdomen blackish. Beneath, 

 paler in colour, the markings more distinct, and the discoidal spot 

 much larger than in I.fausta. 



Female. — Resembles the male, but the brick-red colour is re- 

 placed by white.

 This is an especially Indian genus. In the Archipelago one 

 species is found in Sumatra, two in Java, and one in each of the 

 small islands as far as Timor. It is not known from Borneo or 

 from any other parts of the Archipelago. It seems to inhabit 

 only mountainous and rather dry districts, and this has probably 

 determined its peculiar distribution. Many of the species are 

 very variable, especially in the female sex, and 1 have had much 

 difficulty in grouping them satisfactorily.

This distinct species is probably confined to Java, where it is 

 very scarce.
