Description : Male. Upperside, both wings rich shining deep blue 

 of about the same shade as in C. icetas, Hewitson. Forewing with the costa 

 as far as the subcostal nervure black (except a few blue scales placed 

 between the costal and subcostal nervures towards the base of the wing); 

 the apex broadly black, the inner edge of the black area evenly 

 curved ; the outer margin narrowly and decreasingly black, about 2 

 mms. broad at the inner angle. Hindwing with the costa and ab- 

 dominal margins broadly black, the latter internally becoming 

 whitish ; the basal two-thirds of the discoidal cell shining fuscous ; the 

 apex rather broadly black ; the outer margin with an anteciliary black 

 thread ; a small subinarginal black spot in the first median interspace 

 in one specimen ; the anal lobe black, bearing outwardly a few tur- 

 quoise-blue scales and then a few white scales, anteriorly marked with 

 a ferruginous line ; tails black, tipped with white. Cilia of the forewing 

 black, of the hindwing whitish. Underside, both wings pale leaden- 

 colour, slightly shining, of a little lighter shade than in Tajuria

 wardly narrowly defined with whitish, in the forewing a little out- 

 wardly bowed, commencing at the subcostal and ending on the sub- 

 median nervure, in the hindwing straight from the costa to the third 

 median nervule, thence highly zigzag, and at the submedian nervure 

 recurved to the abdominal margin ; an obsolete darker submarginal 

 fascia. Forewing with a short broad prominent orange band at the 

 extreme base of the costa, very conspicuous in unset specimens ; the 

 usual tuft of pale ochreous hairs attached to the outwardly-bowed 

 middle portion of the inner margin and turned under and forwards. 

 Hindwing with an oval submarginal black spot in the first median 

 interspace, inwardly very broadly (almost up to the outer discal dark 

 line) surrounded with orange, this orange colour being continued to 

 the abdominal margin in a narrow line, beyond which latter is a white 

 line of the same breadth ; the anal lobe bears an oval deep black spot, 

 outwardly bounded by a line of brilliant metallic torquoise-blue 

 scales, these scales being continued into the interspace beyond, that
