from Placer and Sonoma Counties, California, typically rep- 
‘resent the species and seven from Placer and Lake Counties, 
California, represent the variety, while there are 36 others 
from Placer, Lake and Sonoma Counties which are more or 
less intermediate in the color of the fore wings and dorsum. 
As most of these latter approach the variety more closely 
than the species, I have grouped them with the former, 
but the standing of this variety appears now to be less certain. 
From the distributional data it appears that the variety 
niveipennis is not a regional one but rather a case of albinism 
occurring wherever the species is found. 
Euphyllura arctostaphyli bifasciata new variety. 
This variety resembles the species in size, structure of body and gen- 
eral appearance, but differs in wing colors. The forewings have a con- 
spicuous white or pale band transversely at base and another near apex 
which is more or less angled and does not extend entirely across wing. 
The color of the remainder of the wing varies from dark as in the species 
to very light brown as in the darker representatives of the variety nivei- 
pennts. 
In the series of specimens from which the writer prepared 
the description of this species in his monograph were a few 
specimens with this type of wing but it was deemed advisable 
not to separate these few into a variety. However, Mr. 
Giffard now presents seventeen specimens of both sexes and 
no truly intermediate forms to indicate that this is a variable 
characteristic. The statement, therefore, in the monograph 
(Wes. Nat. Mus. Bul. 85,p. 116), “forewings . . . often 
with a prominent white fascia at basal third and sometimes 
a whitish area or fascia subapically,’’ should be omitted from 
the description of the species and applied to the variety 
bifasciata. 
Described from seventeen males and females collected by 
W. M. Giffard at Donner Lake, Placer County, California, 
August 24, 1917, and at Summit in the same county.
