1782 BUTTERFLIES BEYOND NEW ENGLAND. 



half of tlie continent ; indeed the species here described is the single one 

 which is found in the eastern half and this extends across the continent. 



The butterflies are weak winged insects of delicate texture and generally 

 feeble and often vaguely defined markings, usually of some shade of buif ; 

 they belong to the first section of Satyrid genera as defined in the present 

 work, the eggs being vertically ribbed and cross lined excepting at base, 

 the young caterpillar having bent cuticular appendages, here very short, 

 the mature caterpillar a smoothly rounded head uncrowned by projections, 

 and with shoi't tails, the chrysalis a blunt anterior extremity, and the but- 

 terfly an angulate, inferiorly produced, outer extremity to the cell in the 

 fore wings. 



Notwithstanding that the genus is so much better developed in Europe 

 than in America and in America is almost absolutely confined to the west, 

 it was reserved for the indefatigable Edwards of West Virginia to give us 

 our first knowledge of its early stages. 



COENONYMPHA INORNATA. 



Coenonympha inornata Edw., Proc. acad. uat. sc. Philad., 1861, 163 (1861). 



Imago. Head covered with pale Ijrownish yellow scales and hairs ; palpi the same 

 with a few scattered blaclv ones; antennae clay brown, heavily flecked above with 

 brownish, excepting generally at the extreme base of the joints. 



Upper surface of the wings pale yellow bnU', sometimes nearly uniform, at other 

 times with the markings of the under surface showing through, especially where these 

 are heavy ; fringe concolorous with the surface. Beneatli, tlie same ground color as 

 above, at least upon the fore wings, but the basal half or three-fifths of the hind 

 wings heavily or lightly begrimed with a more or less dense sprinkling of black scales ; 

 the same are also found at the extreme base of the fore wings, and to a very slight ex- 

 tent just beyond the middle of the wing upon the costal border ; an extra-mesial, pallid 

 or white baud, with somewhat irregular contour, crosses the /ore wings fromthemiddle 

 of the outer two-thirds of the costal border toward a point just within the termina- 

 tion of the inner margin ; it is distinctly edged only upon the inner side, where the 

 wing is slightly darker than elsewhere ; it is of varying length and depth, sometimes 

 very obscure; there is sometimes in the first inferior subcostal interspace, midway 

 between the cell and tlie margin, or rather nearer the latter, a minute, white-pupiled, 

 round black spot. Hind wings with a similar but more irregular and tortuous extra- 

 mesial, pallid or white stripe of irregular width, being widest beyond the cell, the 

 outer extremity of which it turns inward to meet. The outer margin of all the wings 

 lined with a fine Ijlack thread. Expanse of wings, 31-36 mm. 



From drawings by Gosse, Edwards finds this species occurring at Car- 

 boncar, Newfoundland. Excepting for this occurrence, the butterfly has 

 not been taken east of Lake Winnijjeg, having always been supposed to be 

 a northern species of the western half of the continent, where it occurs not 

 only in British America, as far as Vancouver Island and at Calgary and 

 Edmonton (Geddes), but in Montana. Nothing is known of its trans- 

 formations and seasons, excepting that in Newfoundland Gosse took it 

 in July and August.
