$ . Pale, creamy brick-red ; with black markings. Fore- 

 wing : costa broadly banded with black ; a large, sub-quad- 

 rate, slightly arched, black spot united to the costal band at 

 extremity of diseoidal cell ; a broad, black band along hind- 

 margin, widest at apex, and containing two rows of spots of 

 the ground-colour, the inner row consisting of larger spots 

 than the outer, which is occasionally obsolete ; the creamy-red 

 ground colour becomes gradually paler towards hind-marginal 

 band. Hind-wing : a similar hind-marginal band to that of 

 fore-wing, and likewise containing two rows of spots, which 

 are frequently indistinct. UNDER-SIDE. Greenish-yellow. 

 Fore-wing : Flushed with orange-yellow from base ; a black 

 disco-cellular spot ; three quadrate black spots form a short 

 transverse row, near anal angle, not far from hind-margin. 

 Hind-wing : irrorated with grey specks ; sometimes with a 

 disco-cellular, blackish spot. 



? . Markings similar, but ground-colour yellowish-white, 

 sometimes flushed with creamy-red from base. UNDER-SIDE. 

 Paler ; flushed with sulphur-yellow from base. Fore-wing : 

 disco-cellular spot larger, red-centred ; beyond middle, a 

 transverse row of reddish spots joins the black spots near 

 anal angle, which are also tinged with reddish. Hind-wing : 

 disco-cellular spot almost wholly pinkish-red ; beyond middle, 

 a sinuate row of spots of the same colour, parallel to hind- 

 margin. 



This species approaches the Genus Co lias, Fab., in colour and marking, 

 as is very noticeable when it is compared with Colias Electra, Linn. It is 

 very widely distributed.
