Persia up to the edge of the Khivan Desert. I would 

 draw your attention to the fact of its occurrence at 

 Malatia, as we see here the whitish Petiia and yellow 

 var. Mesopotamica overlapping each other. 



Anthocharis Tomyris, Chr. 



^ . The fore wings are white, with a pale sulphurous tinge ; the 

 discoidal spot is reduced to a minimum, and is triangular in shape, 

 the base thereof being angled inwards. The costa is broadly 

 greyish from the disco-cellular vein to the margin, extending from 

 the base of wing to the discal spot ; the apical patch is pale 

 greenish grey, much reduced in size, and extending further along 

 the costa than down the posterior margin, with no trace of the 

 transverse band, but there are four small yellowish dots on the 

 costa within this area. Costa pale pinkish ; fringes slightly tinged 

 with pink. The hind wings are rather yellower in colour than the 

 fore wings, showing the dark under side through, and also exhibiting 

 through the single whitish central spot of the under surface. The 

 roots of all the wings are blackish. Beneath the fore wings are 

 paler than above, with the greyish discal spot smaller. The apical 

 area is yellowish green, finely irrorated with brownish grey. The 

 hind wings are greenish, very finely irrorated with brownish grey, 

 with a single whitish dot in the centre, on the posterior margin of 

 the median cell. 



2 . This sex is quite remarkable in the pattern of its fore wings, 

 which are sulphurous greyish white, with the dark grey discoidal 

 spot very large, roughly quadrangular, and extending nearly half 

 across the wing, and right up to the costa, from whence to the 

 roots the costa is broadly bordered with grey. The apical patch is 

 dark grey, large, extendmg broadly right down the posterior 

 margin almost to the anal angle, which angle is dusted with dark 

 scales extending upwards and connecting the dark margin there- 

 with. The whole of the inner margin is likewise more or less 

 dusted with dark scales. The costa is finely pinkish. Hind wings 

 greyish sulphurous yellow, slightly dusted with dark scales, which 

 are particularly noticeable round the posterior margin and along 

 the inner edge of the median cell. Fringes of both wings slightly 

 rosy. Beneath the fore wings are whiter than above, the discal 

 spot showing through almost as large as above ; the costa is grey 

 from this spot to the base, and has an internal broad border of 

 yellow, which is continued up to the apical area ; this apical patch 

 follows the shape of the upper surface very closely, but is yellowish, 

 finely and densely irrorated with brownish grey, the irrorations
