Under side. Two black spots in discoidal cells as above ; a pro- 

 minent white spot between the discoidal nervules, and two 

 indistinct and much sullied white spots in the first and second 

 interspaces. The remaining spots of both wings ai-e enlarged into 

 long black streaks between the nervules.

Descrijition. — This aberration diff'ers from the typical form .as 

 follows : — 



Upper side. — Fore tving. The three white elongate lunules which 

 are so prominent a feature in C. nicobarica aie reduced to three 

 obscure white streaks, the white spot below them much sullied 

 with black atoms and reduced in size ; the discal row of white 

 spots outside the afore-mentioned lunules is wanting, and the 

 marginal series of fine white lunules is obsolescent. 



The spaces between the black lines in the cell are much infus- 

 cated, and there are two large black spots in the first and second 

 median interspaces. 



Hind tving as in typical form, but the subcostal black spots are 

 enlarged, the discal black spots are almost obsolescent, and the 

 submarginal black sjDots and lunules are almost obsolete. 



Under side. Cell of fore wing much infusci\ted between the 

 lines ; no pale discal fascia beyond the cell ; the seiies of lanceolate 

 spots in C. nicobarica replaced by a series of small white streaks 

 much sullied with black atoms. 



Hind tving with the black markings of the two inner bands 

 somewhat enlarged, and without the adjoining white bands ; the 

 submarginal series of black spots in a wliite band obsolete, and its 

 place only indicated by a row of very indistinct and obsolescent 

 yellow lunules. 



The specimen is a male taken at Port Blair.
