24 Mr. H. J. Elwes' additional notes 



and Sagartia by characters which, though in this genus 

 not so satisfactory as one might wish, yet, if constant, 

 would enable one to recognise it with certainty. It was 

 found in the Alai and Hazret Sultan Mountains of 

 Turkestan by Haberhauer. 



The principal characters by which it may be known 

 are the white spots on the middle of the under side of 

 hind wing, which are never surrounded by a ring of 

 brown or yellowish (this seems to be also the case in 

 C. Wiskotti), the colour of the antennae, and the hair 

 of the head and thorax, which have none of the pink 

 colouring found in the other species of this group. 



My specimen from the Hazret Sultan has, however, 

 the antennae, as in Sagartia, unlike the other two from 

 the Alai. Before deciding as to whether this is really a 

 good species, it would be desirable to see if specimens 

 of Sagartia occur in the as yet unexplored mountains of 

 the Perso-Turcoman frontier to the eastward of its 

 hitherto only known habitat, as, if they do, they may 

 possibly present intermediate forms. 



Colias Ladakensis, Feld.

 1865.

 t. xxxi., fig. 13. 



Since writing on this species I have seen the types of 

 Ladakensis, which is undoubtedly the same as Shipkee, 

 and, though there is still some doubt as to the priority 

 of the names, Felder's is so much the best that I think 

 it should be adopted. It appears to me, after the 

 examination of a number of specimens, to be so well 

 distinguished from all allied forms, both by the colour 

 of the upper and under side, and by the j)eculiar shape 

 and colour of the central spot on under side of the 

 hind wing, that it may very well stand as a good 

 species. 



The females appear to be distinguished by the slight 

 orange tint of both wings on the upper side.
