$ . Pale sulphur-yellow ; with dusky -blackish hind-mar- 

 ginal borders. Fore-wing : dusky-grey at base ; costa dusted 

 with grey ; hind-marginal band bruad at. apex, divided by 

 spots of the ground-colour arranged as in the $ Electra, but 

 not so clearly defined, being more contiguous, the spot 

 between second and third median nervules usually connected 

 with the ground-colour, in consequence of the inner portion 

 of the blackish band becoming obsolete on, or just above, 

 third median nervule ; disco-cellular spot large and black, as 

 in the ? Electra. Hind-wing : base blackish-grey, but re- 

 mainder of wing not clouded as in Electra ; disco-cellular 

 spot large and conspicuous, orange-yellow ; hind-margin 

 faintly and irregularly bordered with blackish, with, in some 

 specimens, traces of an inner stripe, forming with the outer 

 border indications of a broad band enclosing yellow spots. 

 UNDER-SIDE. Marked very similarly to C. Electra. Fore- 

 wing : pale-yellow, as on upper-side ; disco-cellular spot 

 usually with a paler centre ; apical portion of wing lighter 

 or darker chrome-yellow ; transverse row of ferruginous and 

 blackish spots not so dark as in C. Electra. Hind-wing : 

 ochreous-yellow mingled with greyish ; a large, and a small, 

 silvery disco-cellular spot, touching each other, surrounded 

 by distinct ferruginous rings, well-defined on their outer 

 edge ; a transverse row of ferruginous spots near hind-mar- 

 gin, arranged as in Electra. Antennae, legs, and edges of 

 wings rose-pink.
