PSYCHE. 



[Fehruiiry 1S90. 



A. adiaiitc is a form which both 

 Strecker and Edwards consider distinct, 

 and which appears to be very local. On 

 the coast of California, according to 

 vStrecker's information, it is now extinct, 

 and all the male specimens (I have seen 

 no females) in Mr. Godman's and my 

 collection were evidentl}^ taken many 

 years ago. But, though the markings 

 on the under side are neai^ly obsolete in 

 some cases, and in all faint compared 

 Nvith those of zcrene or moi/ticola^ }et 

 they seem to be quite identical, and I 

 should certainly be inclined to set it 

 down as a variety of one of those species. 

 This is just a case in which one would 

 be guided by the opinion ot local collec- 

 tors, but neither Mr. H. Edwards or any 

 one else of late years seems to have men- 

 tioned this species, and the opinions held 

 twenty-five years ago, when Dr. Behr 

 was an active collector, are not conclu- 

 sive. 



The intricacy and confusion of no- 

 menclature among the next group of 

 Argynnides, which inhabit the Rocky 

 Mountains and Pacific States, is as great 

 as among the last, but 1 have in this case 

 followed Edwards's identifications of 

 Behr's and Boisduval's species, which 

 are supported by the named specimens 

 sent me by Mr. H. Edwards, rather than 

 the arrangement of Strecker's Catalogue, 

 which makes 7)io7itivaga and egleis 

 varieties oi zercne, Bdv. I cannot, how- 

 ever, follow Edwards in separating 



scribed from some small examples of i;-«;««(^r/, given 

 by Mr. O. B. Johnson of Oregon, to Mr. Dodge, of Ne- 

 braska, who gave them to Mr. W. H. Edwards. Some 

 of the same catch and lot were also given to Mr. Strecker. 



clio and artonis from cury)iovic, and 

 Geddes, who took them in the Northern 

 Rocky Mountains, agrees with me in 

 considering them as synonyms. As to 

 opis and bischoffi^i I am more doubtful, 

 having seen but few specimens ; but in 

 these, as well as in Edwards's figures I 

 can see no specific characters, and should 

 consider them as northern varieties, 

 diftering only, as might be expected, in 

 rather smaller size and duller coloration. 

 Whether tnontivaga and its var. egleis 

 are really distinct from etcrynoj/ie and 

 its varieties is hard to say ; they seem to 

 have the fore wings rather longer and 

 the underside less tinged with green : 

 thev may, perhaps, best be treated as the 

 west coast representative of eurynome. 

 Edwards says oi egleis ( Ca)i. ent. v. 3, 

 p. 54) that whatever the variation in 

 other respects (and he allows it to be 

 very variable), the spots of the second 

 and third rows on the under side of hind 

 wings are heavily edged with black on 

 the basal side. 15ut I have specimens of 

 montivaga., collected by Monison in 

 Nevada (of which sixty were also exam- 

 ined by Edwards), and others from the 

 Sierra Nevada, California, named ruon- 

 tivaga by H. Edwards and Strecker, 

 which have the same character, and in 

 some specimens of eurynome taken by 

 myself in Yellowstone Park, the same 

 black edging is more or less perfect. 



I have also specimens oiarge., Streck. 

 from Strecker and Mr. Holland, both 

 from Spokane P'alls and California which 

 are undoubtedly the same as erinna^ 

 which was described in 1SS3 as a var. of 

 eiirvfiofnehy Edwards, and in his Cata-
