1540 THE BUTTERFLIES OF NEW ENGLAND. 



l.C mm.; of fifth abdominal segment, 2.5 mm.; of head, 2 mm. Described from 

 a blown specimen received from Mr. Riley. 



Prof. E. A. Popenoe has kindly sent me the following description of the living full- 

 grown caterpillar, taken by his assistantMr. Marlatt : — "Head, first [thoracic] segment, 

 first two pairs thoracic feet brownish black ; head darker than first [thoracic] segment, 

 and thickly covered with yellowish hairs. Body greenish, thickly armed with short, 

 whitish, knobbed haii's; it tapers posteriorly, and is thickest in middle segments. Two 

 broad, whitish, dorsal lines, and two lateral lines, all indistinct. Stigmata yellowish. 

 Abdominal feet tipped with yellow-brown. Length, 17 mm." 



Abbot's painting (77 : 17) shows the head brownish-black; the body pale, yellowish 

 green, the sides with a very broad, pale band, enclosing in the middle an interrupted, 

 slender, rather dark green stripe ; a faint, darker green stigmatal line ; whole body 

 covered with greenish yellow hairs, which are tolerably conspicuous; first thoracic 

 segment reddish, with longitudinal, broad, whitish patches on the anterior half ; legs 

 dark; prolegs green. Length, 30 mm. ; height, 4.25 mm. 



Chrysalis (85 : 35). Dark green, heavily marked with dark, reddish brown, the pro- 

 thorax being margined with it, the antennae and legs heavily marked, and the wings 

 longitudinally and rather extensively streaked ; the abdomen is also furnished with 

 longitudinal rows of small spots of the same situated near the sutures, and arranged 

 apparently in laterodorsal, suprastigmatal and infra.stigraatal series; a moderately 

 broad, stigmatal band is free from them. Length, 20 mm. ; height, 5 mm. De- 

 scribed from Abbot's painting. 



The following description was received from Prof. E. A. Popenoe, the only one yet 

 taken from life, so far as I know : — " General shape of pupa of this subfamily. Body 

 yellowish white, eyes reddish, red lunar spots at prothoracic suture ; cremaster reddish, 

 much elongated and armed with curved or clubbed reddish spines. Body including head 

 and eyes thickly covered with whitish hair; dorsum dotted with black, arranged on 

 the segments in two transverse rows. 15 mm. long." 



Comparisons. The Cuban species H. syrichtus, certainly closely allied to this, 

 difl"ers from it in being decidctlly more uniform in markings in the earlier stages, as 

 may be seen by the following descriptions which 1 have drawn up from notes given me 

 by Dr. Gundlach, and his printed descriptions and those of Dewitz. 



The head of the caterpillar is brownish black, rough with fine white hairs. The 

 first thoracic segment is ferruginous with two ochreous longitudinal stripes on either 

 side; the rest of the body is green with scarcely distinguishable bright points, and 

 covered with very many short, white hairs apically enlarged, situated on the middle of 

 the subsegments. There are scarcely distinguishable dorsal, laterodorsal and stigma- 

 tal stripes of a slightly darker green. The tlioracic legs are brown with black claws. 



The chrysalis is pale green with a brownish tinge above, clothed with many short, 

 white hairs. The head is somewhat more olive, and the wings are tinged with orange, 

 as is also the abdomen, and bordered next the spiracle of the fourth abdominal seg- 

 ment with fuscous. A lateral line of black points extending from the mesothoracic 

 segment Ijackward over the whole abdomen. The minute papillae supporting the 

 hairs are black. Stigmata brown ; the prothoracic stigmata large, swollen posteriorly, 

 margined with black. 



Distribution (29 :2) . TliLs butterfly belongs to the Carolinian fauna 

 but is also very abundant in the southern parts of the Alleghanian. It 

 is one of the commonest, if not the commonest, of the southern Hesper- 

 idae, and extends from the Atlantic to the Pacific. East of the Rocky 

 mountains the northernmost points from which it has been specifically 

 reported (excepting that it was found at Medicine Hat, Assiniboia, by 

 Geddes) are at Heart River Crossing and the Big Muddy, Dak. (Allen), 

 in Iowa at Ames (Osborn) and Davenport (Putnam, Austin), Wiscon-
