We have not seen this species, the male of which is described as 

 light greyish blue above, with the fringes of both wings alternately 

 black and white below. 



Mr. Misldn notes : " This is near to sehce and the markings are 

 similar to that species, but the decidedly different tint of blue, the 

 absence of metallic sheen, and the somewhat larger size seem to 

 distinguish it." He says of the female, "As in male, except that 

 the blue is much less pronounced, the upperside being almost black." 



It is notable as being the only species which has non-metallic 

 blue.
