right along the sub-costal vein to its end, the abdominal space and fold also blackish, 

 the rest of the wing blue. Underside as in the male. 



Expanse of wings, $ 1-^-^, $ Ij^ inches. 



Habitat. — Assam. 



Distribution. — Hewitson's type female is labelled " India," de Niceville's type of 

 carmentalis, a male in the Indian Museum, Calcutta, came from the Khasia Hills ; we 

 have received a good many examples of both sexes from the same locality ; the females 

 correspond with Hewitson's type, and the males with de Niceville's figure and 

 description ; we therefore conclude there can be no doubt that de Niceville's carmentalis 

 is the male of Hewitson's ister.

Imago. — Male. Upperside cerulean-blue. Forewing with a black costal band, 

 commencing narrowly at the base, broadening gradually to the apex, and narrowing 

 gradually hindwards to the hinder angle. Hindwing with the costa and apex with a 

 narrow blackish band, continued in a line from vein 5 to the anal angle ; abdominal 

 fold grey ; anal lobe black, covered with blue scaling in fresh specimens ; tails black, 

 tipped with white ; the glandular patch below the costa brown, surrounded by pale 

 bluish-white, both wings with the veins very finely black. Cilia blackish-grey, with 

 pale tips. Underside rufous-greyish-brown ; a broad white straight band from the 

 middle of the costa of forewing to a little above the anal angle of the hi'ndwing, even 

 on the forewing, its lower part merged in a large white patch on the hinder margin 

 which often extends to the hinder angle ; on the hindwing the band narrows gradually 

 hindwards to a point, its lower part curving slightly inwards ; a black discal line of 

 thin lunules across both wings, more or less disconnected on the forewing, very slightly 

 outwardly curved, its lower portion with an outward bend ; on the hindwing it curves 

 outwards, then inwards, then in two angles which are broadly outwardly margined with 

 white, it bends round close to the anal lobe, to the abdominal margin a little above it ; a 

 sub-marginal indistinct series of pale brown lunules half way between the discal line and 

 the margin ; on the hindwing there are indications of a double series marked with pale 

 whitish, a black spot on the anal lobe, another in the first interspace, both capped with 

 orange, the latter with some pale blue, and black and white scales below it and similar 

 scaling in the interspace between the two spots ; terminal line black, a fine white thread 

 inside it which becomes obsolete upwards. Antennae black, ringed with white, club
