PAPILIONID^. 



margin and fringe rose-red : secondaries with costal margin and fringe as in the primaries ; a 

 discal arched series of indistinct plum-coloured dots, beginning 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. 



" Female. 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 confluent; a submarginal series of 

 irregular yellow spots bounded internally by an arched scries of heavy black lunules. Under 

 surface exactly as in the male. Expanse of wings 2 inches 8 lines. 

 Albino female. 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 grey, 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 primaries 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 distinguished by the deep coloration of the 

 under surface." {Butler, I.e.)

"Allied to Colias hi/ule, from which it chiefly differs in its smaller size, elongated narrow front 

 wing8, and pale submarginal markings." (Butler, J. L. S.) 



Several interesting specimens arc figured on Plate XXXIV. Of these 

 figs. 8 & 1) sliow the largest and smallest examples I have, so far, seen of 

 this species ; the former is from Chia-ting-fu, and the latter from Ichang. 



C. liyale from Eastern Asia ranges in colour in the male from pale wliitish 

 yellow (fig. 7) to canary yellow (fig. 8), and the black markings graduate 

 between the two extreme examples represented by figures 1, Chang-yang, 

 ;nid 4, .I;i|)ai!. In several specimens the Idack markings on the seccmdarics 

 lire rethiced to almost vanisliing point (fig. 7). The (n-ange central spot of 

 secoiuhiries is also subject to consideral)le modification, and may be well 

 dev('h)ped (fig. 8), faintly defined (fig. 7), (u- entirely absent; variation in tbis
