to withdraw it. The species shows considerable variation, and a 

 form which I had intended to describe as a variety has the wings 

 more 3'ellowish, the veins paler and the tip of each one very 

 slightly but distinctl^^ darkened at the wing-margin. In the 

 Indian Museum are one & and three 9 2 from Sukna (500 ft.), 

 i-vii-o8 ; Puri, Orissa, 22-X-08 [both Annandale]; and Calcutta, 

 g-xii-07. I took it at first for a " plains " variet}^ of my supposed 

 new species, but intermediate individuals connect it with the 

 typical form. 



The precise mathematical distinctions appertaining to the 

 bands on the legs, as given by Mr. Edwards, do not hold good, as 

 they^ exhibit considerable variation.
