This is another of the many beautiful species of Chalcosiida 

 found in Northern India, and it was first recorded from 

 Assam. The fore-wings measure nearly three inches in expanse, 

 and are green, with a yellowish-white patch at the base, two 

 yellowish-white spots placed obliquely before the middle, a 

 third at the end of the cell, and an irregular sub-marginal 

 row of smaller and whiter spots. The hind-wings have the 

 basal half orange-yellow (with the extreme base black), passing 

 into violet towards the apex, and marked with two rather large 

 white spots. The thorax is velvety-black, shading into violet 

 at each extremity. The abdomen is orange, with the base 

 violet. The under side of the body is violet-blue, the segments 

 of the abdomen alternately variegated with white and black ; 

 the black portions of the wing are also strongly glossed with 

 blue beneath. 



This species has some resemblance in pattern and in the 

 distribution of its colours to Episteme, and other genera of 

 Agaristidce.
