618 Characteristics of the Insect- Fauna 



have been described and figured from northern Europe, I 

 cannot, from the confusion in which the species of this 

 genus appear to be, and from the want of any specimens 

 from other quarters, at present determine, — but satisfy my- 

 self, on this occasion, with a more detailed description of 

 the species than has yet been given ; only suggesting, that 

 should it ultimately prove to be distinct, it will only be 

 a case analogous to what we find in the species next to 

 be mentioned.* 



I have found at three localities so separated as the sum- 

 mit of Mount Madison, the head of Tuckerman's Ravine, 

 and a short distance above the Ledge, (all, it will be no- 

 ticed, within the subalpine region,) a species of Arg-ynnis, 

 described below in honor of the god of the mountains, be- 

 longing to that group of the genus to which A. Amathnsia 

 Ochs. pertains. Without a critical examination, it would not 

 be distinguished from A. Boisduvalii Sommer, which I do 

 not consider, as Boisduval does, to be synonymous with 

 A. chariclea Ochs. The character of the relationship of 

 A. Boisduvalii and A. Montinus is such that they would 

 come under the denomination of representative species in 

 the limited sense to which I have attempted to restrict it 

 in my paper on the Genus Colias.f To the points of dis- 

 tinction between them I shall not, however, here allude, 

 reserving such remarks for a future occasion, when I shall 

 speak at length of the boreal species of this genus ; but we 



* 111 a letter written by Dr. Harris to Mr. K. Doubleday, of Kngland, dated March 

 24, liJ4'J, occurs this remark: " Boisduval, in his Icoues Historiques des Lepidop- 

 t^res nouveaux, &c.. Vol. I. p. 197, under Chionobas Also, makes the following 

 blunderino; remark, 'J'ai re^u de M.John Le Conte, sous le iiom d'erilinsn [!] 

 de Harris, [!] un individu pris dans les montagnes calcaires [ !] de New Hainp- 

 shire, qui me parait appartenir a cette e«p6ce.' Boisduval's Also, published in 

 1832, is very possibly identical with Say's semidtd, published in lS2i?; and if so, 

 the latter name alone can stand. The specimens which Le Conte sent to Boisdu- 

 val lie received from me, with Say's Aiyeria exitiosn ; whence, probably, the 

 blunder of the specific .name. My specimen ol Ilijiparihia seinkku was taken on 

 the summit of Mount Wsushington, one of the loftiest peaks of the White Moun- 

 tains, which, by the way, are not "montagnes calcaires."
