Wings above fulvous ochreous; costal margin, base, and outer 
margin brown, Also on malesa broad dash of brown posterior to discal 
space, outwardly including it in part, sometimes entirely and blending 
with costal margin. Secondaries somewhat paler than primaries, as are 
all the wings of the female. Beneath, primaries somewhat paler than 
above, somewhat striated with black along costa, hoary and marbled at 
apex; brown marginally. Secondaries, heavily striated and marbled with 
black on a dull white ground, these, as is usual, forming a broad more 
or less definite median band; darker towards margin.. The primaries 
are more produced in the males than in the females, and the costa is less 
arched. ‘This is however a tendency of the genus, Ocelli variable, the 
one near apex of primaries, and near anal angle of secondaries more 
permanent, the former, as far as I know, always present. Expands about 
2.50 inches. Cal., Nevada, and Northward.

Differs in having the ocelli of the primaries when present, not ina 
straight line. Vancouvers I. 
I have given this species conscientious study, and hee tried to con- 
vince myself that there are here 4 species or anything more than one 
and one variety. But I can not believe we have to do with more than 
one species and am not fully convinced of the validity of gigas as a 
variety. The yarious names have been based upon markings which are 
notably variable in all species of the genus. Mr, Butler’s words with 
regard to Coenonympha; have more appropriateness spoken with regard to 
Chionobas: ‘‘the form of the local bands, and the constancy of the aol 
can not be relied on” 
In the pre ommtion of this paper I have followed Staudingers arrange- 
ment of the species. The writings of Moéschler and Scudder have not 
been overlooked; but I cannot agree with their conclusions, 
For the generic characters of Chzonobas and Coenonympha we refer to 
the synopsis of genera in Vol. VI.

comparative with J. /rzfic:, Riley, with which it is nearest allied.
