examples from the Khasia Hills, whicli have been submitted to Dr. Chapman for 

 identification ; it is in Major Ty tier's collection from the Naga Hills, and in Colonel

 Bingham, Fauna of Brit. India, Butt. ii. p. 364 (1907). 



Eyes naked ; neuraticm much as in Plebeius and Lycaena ; also as to the 

 structure of the antennae, palpi and legs ; in the hindvving, however, veins 3 and 4 are 

 emitted from the lower end of the cell, whereas in Plebeius and Lycsena vein 3 is 

 emitted from a little before and 4 from the end ; the genitalia are quite difi"erent to 

 that of the Plebeinse or Lycseninse and closely resemble the genitalia of the Everids, and 

 Dr. Chapman and Mr. Bethune-Baker are both of opinion that this genus must stand in 

 the sub-family Everinse. The character of the wing-markings are very distinctive.
