(Ef. jutta.—After examining a series of ten males and 
seven females from Norway, Sweden, Finland, Esthonia, 
and Russia, five males and four females from Pokrofka, 
on the Upper Amur, among which are several sent me 
by Dieckmann as var. magna, Graeser, and a pair from 
Labrador, six pairs from Laggan, three males and a 
female from Quebec, I find a great amount of variation 
both in the expanse, number and size of the ocelli, and 
in the distinctness and shape of the band on the under 
side. The Asiatic specimens on the whole are distinctly 
largest, though not more so than some from Southern 
Norway. The American specimens average considerably 
smaller than either European or Asiatic ones, though I 
have two from Esthonia as small as any of them. I 
should be able to pick out nine out of ten American 
specimens by the following characters :—Ground colour 
of the under side more distinctly freckled on both fore 
and hind wings, band less distinctly defined, ocelli 
smaller :—but I do not think that there is any ground for 
treating the American form as a distinct variety. The 
sex-mark is very conspicuous in all my fresh males, 
but least so in the Asiatic ones; the number of ocelli 
varies from five in the fore wing, of which the one in 
cell 4 is always the smailest, and usually obsolete; and 
the largest in cell 2 (very rarely absent) to one; incell 5; 
and from 4 in the hind wing, of which only those in cells 
2 and 8 are usually present, and always the largest, to 
none; in those cases where the ocelli are nearly or
