This is another of the many beautiful species of Chalcosiidce 

 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 

 Agaf'istidce.
