with yellow ; discal spot of the fore wings very faint, being merely 
a small black ring, that of the hind wings being represented by a 
faint orange ring. Under side appears to resemble that of C. Hecla, 
but is paler, the hind wings being yellowish green ; the pearly 
discal spot is double. Described from Menetries’s figure. I have 
never seen a specimen, and therefore cannot say to which group of 
the genus this species rightly belongs ; the figure puts one in mind 
of Hecla more than of any other species. Habitat, near the Vilui 
Eiver, Central Siberia. 
C. Aurora, var. foem. Chloe, Evers. Bull. Mosc. 1847, ii. 
p. 73, t. 4; H. S. 457-8. — Bears the same relation to Aurora as 
Helice to Edusa. It resembles the orange female of Aurora, with 
the exception of the ground colour, which is white tinged with 
greenish yellow, and dusky towards the bases. The discoidal spot 
of the hind wings is orange. Habitat, Amur. 
C. Alpherahi, Stgr. — Slightly larger than Phicomone ; the colour 
of the wings is brighter, and the border is darker. The female is 
clearer and greener in colour in the discal portions of the wings. 
Under side pale greenish grey, almost without any markings ; 
there is a central pearly spot. Habitat, Turkestan. 
C. Wiskolti, Stgr. — Size of Aurorina. The wings are greenish. 
Fore wings with a very broad border extending over a third of the 
width of the wing ; the discoidal spot is long and narrow. The 
hind wings have a broad border similar to that of the fore wings, 
but veined with greenish yellow. Under side greenish. Fore 
wings with a black spot and some obscure spots near the anal 
angle. Hind wings greenish ; discoidal spot small and pearly. 
Fringes of ail the wings greenish yellow. Habitat, Samarkand. 
C. Staudingeri (in coll. Godman). — Very like Hecla above, but 
larger. Fore wings with the discoidal spot long and narrow. The 
hind margins of all the wings have narrow borders, as in Hecla ; a 
narrow rosy red fringe extends round the borders of all the wings. 
Under side : Fore wings greenish, except along the inner margin, 
which is orange mixed with grey. Hind wings greenish ; discoidal 
spot small and pink. Habitat, Kuldja. 
The above three species of Colias are described from speci- 
mens in Mr, Godman’s collection.
