Genus Argynnis 



and some authors are inclined to regard it as being a mere vari- 

 ety, which is a belief that can only be verified by careful breed- 

 ing from the egg. 



(22) Argynnis rhodope, Edwards, Plate XI, Fig. 6, $ , under 

 side (Rhodope). 



Butterfly. — In the male sex the upper side is bright fulvous, 

 with both wings on the inner half heavily clouded with dark fus- 

 cous. The black markings are very heavy and confluent. The outer 

 border is solid black, very slightly, if at all, interrupted by a nar- 

 row marginal brown line, in this respect resembling A. atlantis. 

 On the under side the fore wings are dark ferruginous, on the 

 outer margin rich dark brown. Between the spots at the end 

 of the cell and the nervules below the apex are some clear, bright 

 straw-yellow spots. The upper spots of the marginal series are 

 silvered. The hind wings are dark reddish-brown, very slightly 

 paler on the line of the marginal band. The spots are pale straw- 

 yellow, 'except those of the marginal series, which are distinctly 

 silvered. The female on the upper side is of a lighter and 

 brighter red, with the markings dark and heavy as in the male 

 sex. On the under side the markings in the female do not differ 

 from those in the male, except that the primaries on the inner 

 half and at the base are bright pinkish-red. Expanse, $ , 2.20 

 inches; ? , 2.40 inches. 



Early Stages. — Unknown. 



This striking species has been heretofore only found in British 

 Columbia. 



(23) Argynnis behrensi, Edwards, Plate XIV, Fig. 10, S , 

 under side (Behrens' Fritillary). 



Butterfly. — The male on the upper side is dull fulvous, 

 clouded with fuscous at the base, the black markings much nar- 

 rower and lighter than in the preceding species. The primaries 

 on the under side are pale fulvous, clouded with dark brown at 

 the apex. The subapical spots and the upper spots of the mar- 

 ginal series on this wing are well silvered. The hind wings on 

 the under side are deep reddish-brown, with the marginal band 

 only faintly indicated. All the spots are distinctly well silvered. 

 The female does not differ materially from the male, except in the. 

 larger size and the somewhat paler ground-color of the upper side 

 of the wings. On"the under side the wings are exactly as in the 

 male, with the marginal band even less distinct than in that sex.
