460 Messrs. Elwes and Edwards on 
Chumbi, on the frontiers of Sikkim (c.f. P.Z.8., 1882, 
l.c.). Though these specimens were on the average 
considerably darker than those from Ladak, I did not 
think it necessary to give them another name. Later, 
however, Dr. Staudinger described a form from Issyk-kul, 
which is hardly separable from the Sikkim form under 
the name of palearcticus, and gave mine the varietal 
name of sikkimensis. About the same time Alphéraky 
described the same or a similar form from Lob-Nor, in 
Northern Thibet, where it is found at as low an elevation 
as 8000 ft. Still more recently, Grum-Grshimailo 
collected, in the Koko-Nor district, specimens which 
differ in colour amongst themselves as much or more 
than the Ladak and Sikkim forms previously described, 
one in particular being as dark as the form named iole 
by Leech from Western China and Kast Thibet, and 
having the band on the upper side of both wings almost 
entirely absent. Considering the wide range of this 
species in Central Asia, and the small number of locali- 
ties which have hitherto been explored, I do not think 
we are yet in a position to say how far any of these 
variations are locally constant, for, although iole is at 
first sight abundantly distinct from typical pumilus, the 
clasp-form is identical. 
The Chionobas argenteus of Blanchard, in Gay’s Fauna 
Chilena, pl. 1i., figs. 9—11, and the Arge williamsianus 
of Butler (Cat. Sat. B. M., p. 159, pl. 4, fig. 1), have 
been improperly placed in this genus.
