Male. Uppekside. Both wings dark velvety steel-bhie. Anterior wings, 

 with the basal third steel-blue, somewhat iridescent; the middle third dark 

 velvety blue, in some lights almost black ; the outer third paler steel-blue than 

 the basal third, and iridescent ; costal margin, apex, and outer margin almost 

 black. Posterior wings resemble the anterior wings, but the dark velvety area 

 is not so wide, and encloses across the disc a row of indistinct iridescent steel- 

 blue luuules, those between the median nervules the most apparent. The paler 

 steel-blue marginal area is traversed by a somewhat narrow undulated dark 

 band, and the outer margin is the same colour. The abdominal fold is some- 

 what rufous, a colour which slightly pervades the costal and basal portion of the 



wmgs. 



Underside. Similar in markings to C. Begina ; the steel-blue band which 

 crosses both wings is narrower, and its inner side is much more narrowly 

 bordered by iridescent white. The area beyond the band is darker brown than 

 the basal area, and only faintly tinged with violaceous, the corresponding area 

 in C. Bcgina being much darker and more strongly pervaded by that colour.
