Colias subaurataj sp. n. 



^ . Above very similar in coloration and pattern to the 

 preceding species, but with distinct depressed marginal ti'ian- 

 gular yellow spots, and the wings less irrorated with grey ; 

 the secondaries also without paler submarginal spots, but 

 with a zigzag black line on and between the veins towards 

 the apex ; no distinct apical border, but six large marginal 

 black spots. Below the wings are bright golden orange or very 

 bright ochreous yellow, with the inner border of the primaries 

 lemon-yellow ; three large black discal spots (as in the prece- 

 ding species), two blackish dots on the radial interspaces, and 

 two brownish dots on the costa ; a black discocellular spot, 

 with a yellow pupil ; costal margin and fringe rose-red : 

 secondaries with costal margin and fringe as in the primaries ; 

 a discal arched series of indistinct plum-coloured dots, be- 

 ginning on the costa with a spot of this colour; a silver spot 

 at the end of the cell with plum-coloured margin and orange 

 zone, and above it a similar but very minute and fusiform 

 spot ; venter somewhat whitish, legs rosy. Expanse of wings 

 2 inches 2 lines. 



$ . Larger than the male ; the basal area more densely 

 irrorated with greenish grey : secondaries densely irrorated 

 with greenish grey, the orange spot very large and dark ; 

 marginal black spots diffused inwardly, the first two con- 

 fluent ; a submarginal series of irregular yellow spots bounded 

 internally by an arched series of heavy black lunules. Under 

 surface exactly as in the male. Expanse of wings 2 inches 

 8 lines. 



Albino ? . Above with the ground-colour creamy white, 

 the primaries bluish grey towards the base ; marginal spots 

 obsolete, otherwise as in the ordinary form : secondaries 

 densely irrorated with g^Qj, hardly greenish, the marginal 

 black spots united into a border, the submarginal spots fairly 

 regular, internally bounded by blackish spots, but only very 

 distinctly towards the costa ; orange spot rather paler than in 

 the ordinary female. Primaries below with only the apical 

 area and a suffusion over the discoidal area of the same 

 golden ochreous colour as in the male ; the rest of the pri- 

 maries creamy white, but with the usual markings ; costal 

 margin and fringe red : secondaries as in the ordinary form, 

 excepting that the discal dots are larger. Expanse of wings 

 2 inches 5 lines. 



This is a fairly common species, which may be readily dis- 

 tinguished by the deep coloration of the under surface.
