1130 THK BUTTERFLIES OF NEW ENGLAND. 



tipped, suppoi-lhig wine-glass shaped hairs, having a slender stem half as long as the 

 apical expansion, -vvliich is itself as broad at tip as long, and longer than the basal 

 papilla; the lower hairs are, however, club shaped. Spiracles fuscous. Legs and pro- 

 legs of the color of the body, the apical half of the former more or less deeply fuligi- 

 nous. Length, 2.25 mm. ; breadth of head, .4 ram. ; of body, .4 mm. 



Second stage. Head and body uniform grass green, the latter with a distinct, slen- 

 der, pallid, stigmatal stripe, and sprinkled profusely with fuscous points. Papillae 

 numerous, blackish fuscous, surrounded by a pallid aureole, and surmounted by a deli- 

 cate, straight or scarcely arcuate, black or pallid hair, slightly longer than one of the 

 sections of. the segments. Legs and prolegs concolorous. Spiracles pallid, with dark, 

 testaceous rim. Length, 9 mm ; breadth of head, .9 mm. ; of body, 1.25 mm. 



TTiird stage. Head grass green, with pale hairs arising from minute black papillae. 

 Body velvety grass green, slightly paler on the sides than on the back, witli a faint, 

 darker, dorsal stripe, and a pallid stigmatal stripe, about as wide as the length of the 

 spiracles, broadly bordered below with darker green. The black and white hairs a 

 little longer than one of the sections of the segments, arising from minute black 

 papillae, in a small, pale green aureole. Spiracles luteous. Legs and prolegs pale 

 green, like under surface of body. Length, 12 mm. ; breadth of head, 1.4 mm. ; of 

 body, 1.5 mm. 



Fourth stage. Does not difler from the final stage, except in size. Length, 20 mm.; 

 breadth of liead, 1.5 mm. ; of body, 3.25 mm. 



Last stage (76:1). Head (79:61) grass green, sparsely dotted with minute black 

 papillae, each giving rise to a short, black hair; ocelli pale green, annulate at Ijase 

 with black ; mandibles and labrum edged with blackish. 



Body grass green, beset profusely with microscopic raised points, which are black 

 tipped, except in circular, often confluent spots, in the centre of each of which arises a 

 black, hair-mounted papilla like those on the head, and about as abundantly distributed ; 

 a white stigmatal stripe the whole length of the body, tracked through the middle 

 with an irregular, ragged, discontinuous thread of color, varying from pale lemon yel- 

 low to deep orange red, most highly colored in the posterior portion of each segment; 

 sometimes this stigmatal stripe is followed beneath, especially below the highly 

 colored thread, with more or less extended, but generally very slight, inky patches 

 edging the stripe, which serve somewhat to intensify it. There rarely occurs also a 

 moderately distinct, supralateral, pale yellow thread through the whole length of the 

 body, dying out both in front and behind. Legs and prolegs concolorous ; claws pale 

 testaceous. Spiracles pale greenish testaceous, with a very flue black annulus. 

 Length, 30 mm. ; width of head, 2.5 mm. ; of body, 4.5 mm. 



Chrysalis (84:53). Throughout pea green, the whole surface vermiculate, and 

 the vermiculations crested with paler green, giving it a more or less hoary aspect, ex- 

 cepting in a broad, suprastigmatal band, which continues over the alar ridge to the 

 basal wing tuljercle, and on the top of the frontal tubercle and along a doi'sal line, 

 where the crests are either paler or wholly of the ground color ; a stigmatal yellow 

 band, as broad as the height of the stigmata, often continued along the under edge of 

 the alar ridge and edging the under surface of the frontal tubercle ; wings marked as 

 in E. philodice, and with a similar lateroventral row of spots, here blacki-sh fuscous and 

 often enclosed in a moderately broad, reddish fuscous band crossing the fourth to 

 sixth segments, in which black dots are scattered ; and accompanied by the single 

 black dot on the same segments, found in E. philodice. Length, 22 mm. ; breadth, 

 5.5 mm. ; height, 7 mm. 



Geographical distribution (25 : 8) . This butterfly, which is a western, 

 as philodice is an eastern, species, lias a somewhat unusual distribution. 

 As a rule it is more abundant in the Mississippi valley and westward be- 

 tween the annual isotherms of 40° and 65° or 70°. East of the Mississippi
