258 LEPIDOPTEBA INDICA. 



black, sex mark whitish, prominent. Ilindwing with the greyish-blue colour much 

 more extensive, the costal and apical portions broadly suffused with blackish-brown, 

 narrowing rapidly down the outer margin to the middle, the terminal line darker 

 blackish, a black and whitish mark at the anal angle, veins black. Cilia whitish, with 

 blackish spots opposite the vein ends on the hindwing. Underside dark pinkish-grey. 

 Forewing with some darker grey basal irrorations, a faintly indicated transverse discal 

 brown line outwardly edged with pale whitish, somewhat sinuous to vein 4, where it 

 juts outwards in a square-shaped bend, and then hindwards, being absorbed in the pale 

 part on the lower portion of the wing. Hindwing with the base and abdominal space 

 irrorated with dark grey atoms, indications of a discal outwardly curved irregular line. 

 Antennse black, ringed with white, club with a dull orange tip ; head and body above 

 concolorous with the wings, below dark grey, abdomen whitish. Described from a male 

 examjjle in our collection from the Khasia Hills. 



Female. Upperside, both wings pale blue. Forewing with the costa liroadly 

 black, that colour reaching to the sub-costal nervure, the apex very broadly and the 

 outer margin also broadly but decreasingly black. Hindwing with the costa and apex 

 rather broadly, the outer margin narrowly pale fuscous, a fine black anteciliary thread ; 

 the cilia cinereous. Underside, both wings ferruginous, rather darker on the hindwing. 

 Forewing with an irregular discal darker line, commencing on the costa and ending on 

 the first median nervule, outwardly defined with whitish ; the inner margin broadly 

 pale fuscous. Hindwing with very indistinct discal and sub-marginal line ; the 

 abdominal margin and anal lobe heavily sprinkled with black scales ; the upperside 

 of this species agrees with the description of S. chalyhea, but the under.side is 

 ferruginous, not grey, and the forewing has no discoidal spot; the markings and 

 ground colour of the underside are almost exactly as in Japanese males of *S. frivcddszkyi 

 in my collection, but the latter is considerably paler and the markings are far less 

 distinct ; whether these are specific or sexual difi'erences I am unable to say. 

 Lederer's figure appears to portray a very small female specimen, though he describes 

 it as a male, the figure is very rough and barely recognisable, (de Niceville.) 



Expanse of wings, $ $ ly% inches. 



Habitat. — Khasia Hills, Assam. 



The type, a female from the Khasia Hills, is in the Indian IMuseum, Calcutta, we 

 therefore give de Niceville's description of that sex ; the description and figures of the 

 male are from a perfect specimen received from our native collector from the same 

 locality, and the figure of the female from an example in the B. M., also from the 

 Khasia Hills.
