 Argynnis Artonis. 



Male. — Expands from 1.5 to 1.8 inch. Upper side uniform yellow-fulvous, very 

 little obscured at base; all marks delicate, and as in Eurynome ; the mesial baud 

 on secondaries made up of separated crescents (in the examples under view.) 

 Under side of primaries paler; the marks in cell and those of mesial row re- 

 peated ; the P-shaped spot in cell fulvous within ; the extra discal row but im- 

 perfectly rejieated and all the marginal markings nearly obliterated. Secondaries 

 light yellow-buff, sometimes with little or no fulvous, but in other cases mottled 

 over disk with pale fulvous; the band between the outer rows of spots buff, 

 immaculate; the marginal spots faint, as on primaries; the spots of disk shaped 

 as in Eurynome, but pale-yellow, very slightly edged on basal side with black, 

 often but a few scales; most of those of second row have little dusky spaces at 

 their outer ends ; no trace of silver on either wing. Body fulvous above, yellow 

 below; legs reddish-yellow; palpi yellow, at tip red; antennre brown above, 

 ferruginous below ; club black, at tip ferruginous. 



Female. — Expands 1.9 inch. A shade redder than male, the costa and apex (;f 

 ])rimaries buff; the marginal lines heavier and more or less confluent on both 

 wings; all the markings heavier; the mesial band on secondaries confluent. 

 Under side of secondaries cinnamon-brown over basal area and disk, the apical 

 area and hind margin, as also costa next apex and the upper half of cell, yellow- 

 buff; spots as in the male, the marginal almost obsolete. Secondaries yellow-buff, 

 all spots obsolescent. 



This form has been supposed to be a variety of Eurynome^ with which 

 species it flies in Colorado, but is rare. Mr. Mead met with three or four 

 examples in 1872, though he took great numbers of Eurynome. I have 

 received a single male from Big Horn, Montana ; and recently have seen 

 two females from Wells, Elko Co., Nevada; a region where, so far as I 

 know, Eurynome does not fly. These formed part of the collection of 

 Mr. J. Elwyn Bates of South Abinglon, Massachusetts ; and he informs 

 me that he received twenty-six examples, and that the typical Eurynome
