This pretty species varies a good deal on both surfaces ; the 

 black longitudinal streak on the primaries above is frequently 

 divided longitudinally by an ochreous median vein, and trans- 

 versely by an orange-ochreous bar just before the end of the cell ; 

 the ochreous longitudinal stripe of the secondaries is sometimes 

 expanded so as to leave only a narrow black costal border ; on 

 the under surface there is occasionally a subapical decreasing series 

 of five cream-coloured spots divided only by the nervures (which 

 are dull orange), and the secondaries are cream-coloured, with 

 orange-tawny veins and internal streak : intergrades between the 

 extremes occur.

Every fresh collection brings additional evidence of the varia- 

 bility of this species. The example obtained on March 6th has the 

 two obliquely-placed orange spots just beyond the middle of the 

 primaries unusually large and confluent, two small costal spots 

 being only separated from them by the subcostal nervure. At 

 first sight this variety might be taken for a modification of 

 O. midas, but it is not only too dark, both in ground-colour and 

 spots, but the inner of the two costal spots (which doubtless 

 represents the basal orange dash in C. midas) is much too far from 

 the base to be characteristic of that species, whilst the absence of 

 the spot in the discoidal cell of the secondaries is characteristic of 

 C. quadrisignatus.

The damaged aberrant examples recorded under this species in 

 my paper on Mr. Scott Elliot's collection prove to be extreme 

 forms of the preceding species : I had thought it impossible that 

 C. quadrisignatus could vary so much. C. midas is tolerably 

 constant.
