California Wright we prefer to treat for the present as a separate 

 species as the base of the primaries on underside is orange. It extends 

 from Western Arizona to the San Bernardino Mts., Calif. 



POLYGONIA SATYRUS Edw. 



Chrysoptera Wright (Butt. West Coast PI. XXII, Fig. 222) 

 seems to be nothing but a slight variety of this species in which the 

 subterminal markings are more or less obsolete especially in the 9 ; 

 this form occurs with satyrus together and is quite common among 

 Arizona specimens. 



P. marsyas Edw. 



We are in doubt as to just what this species is ; the original de- 

 scription was drawn up from a pair from California in Coll. Reakirt; 

 later (Butt. N. Am. II, PI. 3, Grapta) Edwards figures the species 

 stating that the type pair, the only specimens known, were collected 

 by Mr. Lorquin in the Rocky Mts. and sent to Mr. Reakirt. The 

 specimens under marsyas in the Edwards' Collection are from Mendo- 

 cino Co., Calif., and are absolutely identical with satyrus but no type 

 is to be found ; Scudder claims that it is a dimorphic form of satyrus 

 but Edwards disapproves of this reference and in his original descrip- 

 tion calls it a small form of comma. Usually a dark form of satyrus 

 from Vancouver Is., B. C, has been considered to be this species and 

 Wright (Butt. W. Coast, PI. 22, Fig. 214) figures such a specimen. 

 We have seen nothing that entirely corresponds with Edwards' figures 

 among our British Columbia series so cannot say if this reference is 

 correct. 



P. silvius Edw. 



This species has caused a good deal of perplexity. In the orig- 

 inal description both $ and 9 from California (Hy. Edw.) are de- 

 scribed. Later (Butt. N. Am. II, Grapta III) Edwards states that his 



9 silvius was bred from a larva taken on Azalea occidentalis in the 

 Yosemite Valley and is merely a slight aberration of rusticus. This 



2 we have been seen in the Edwards' Collection and concur with his 

 reference. The S type of silvius has been destroyed unfortunately 

 (Butt. N. Am. II, Grapta III, foot note) and the original description 

 makes it very doubtful whether the $ also can be referred to rusticus; 

 we would call particular attention to the description of the underside 

 where among other things we read, 'common series of extra discal
