146 LEPIDOPTEBA INDICA. 



both wings below, and has the blue extending further towards the apex of forewing above. 

 On the hindwing there is a well defined dull patch at the base quite free from blue 

 scales, and the tuft of hairs at the base of the hind margin below, which is present in 

 all the other Camenas I know except C. cotys, is absent or very much reduced. The 

 venation agrees with that of C. icetas. 



Described from a single male taken on the Karen Hills at 4,000-5,000 feet.

Imago. — Male. Upperside dark bright violet-blue. Forewing with a narrow 

 costal black band to the end of the cell, the band very broad at the apex, its inner 

 margin curved, and the band narrows down the outer margin to the hinder angle. 

 Hindwing nearly all black, the blue area restricted, much as in the hindwing of 

 P. icetas, the marginal black band a little broader ending in large sub-terminal black 

 spots in the four anal interspaces ; anal lobe black, capped with orange, with a spot of 

 metallic blue scales on its outer part ; tails black, tipped with white. Underside grey 

 with a slight pinkish tint without any gloss. Forewing with a discal, somewhat 

 lunular and slightly outwardly curved fine brown line, outwardly edged with white, 

 from near the costa to the sub-median vein ; the sexual tuft of hairs on the hinder 

 margin bright yellow. Hindwing with a discal line which runs nearly straight from the 

 costa to vein 4, then is continued in three angles increasing in size hindwards and curls 

 in to the abdominal margin a little above the anal angle ; a black spot on the anal lobe, 

 another in the first interspace, both heavily capped with orange ; a white anteciliary 

 line ; both wings with indistinct sub-marginal fascia, more or less obsolescent on the 

 forewing. Antennae black, ringed with white, club with an orange-red tip ; frous 

 l)lack, with a white line on each side of it ; eyes ringed with white ; head and body 

 black above, with blue pubescence, grey beneath. 



Female. Upperside paler than the male, but still of a bright blue. Forewing 

 with the costa to the end of the cell, the apical third, and the outer margin broat^ly 

 black. Hindwing with the costa broadly blackish, the colour extending down to and
