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- 

 pen nis. 



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 

 (U. S. Nat. Mus. Bui. 85, p. 1 16), "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.
