Elongata Stretch, the type of which is in the Neumoegen Collec- 

 tion, has nothing to do with sidphnrica but is very possibly a yellow 

 winged form of superba Stretch which in our opinion must also be 

 removed from association with nevadensis and placed as a British 

 Columbia form of blakei Grt. 



A. blakei Grt. 



The type of this species is at Philadelphia; it represents a rather 

 small form, apparently typical about Denver, Colo. ; we believe that 

 superba Stretch may prove to be a race of this species and that elong- 

 ata Stretch and diecki Neum. should be associated closely with superba. 

 It would not surprise us at all if williamsi Dodge and its various races 

 also proved to be forms of blakei; in a series before us from Glen- 

 wood Spgs., Colo., there are specimens which certainly show affinities 

 in both directions. Usually williamsi can be separated easily by the 

 fact that the transverse white lines of the primaries do not cross the 

 white streak in the fold as is usual in nevadensis and blakei but our 

 Glenwood Spgs. series, which certainly seems to represent but one 

 species, has specimens of both types. For the present, however, until 

 careful breeding can be done the two may be kept separate. 



We should also keep bolanderi Stretch separate from blakei; it 

 was described from Mt. Shasta, Calif., and it seems a risky proceed- 

 ing to sink as synonyms species from two such widely separated locali- 

 ties ; we have never seen any authentic specimens of bolanderi nor do 

 we know if the types are in existence. 



A. williamsi Dodge. 



We have never seen anything that would just match Dodge's 

 figure which seems to be that of a 2 ; it is possible that determinata 

 Neum. is merely the $ ; it is usually considered to be the form with 

 the hind-wings greatly obscured by black but, although one of the 

 types of determinata is such a specimen, the original description 

 clearly points to the more normal form with the central area pink and 

 the name must be restricted to the type in the Neumoegen Collection 

 that bears out this description.
