462 THE BUTTERFLIES OF NEW ENGLAND. 



sliiiiitly pakT on the last two or three abdominal seii'nieiit.s. and, especially above, trans- 

 versely and obscurely marked with pallid brown. Spinules brownish fuscous, darlcest 

 at tip; the apical hairs black and strongly curved. No signs whatever of any latero- 

 dorsal wliite spots on any of the abdominal segments. Prolegs and fleshy parts of the 

 legs of the color of the body, apical joints of the legs blackish fuscous, becoming 

 })lack at tip. Lengtli. 3.5 mm. ; width of head. .(> mm. 



Third sUuic. Head black, provided with long, black hairs; moutli parts l)lacki-<h. 

 ]>ody black or reddish fuscous, crossed transversely by many line, broken, whitish lines 

 wliich i)rincipally form two transverse stripes in the hinder half of each segment. lu- 

 frastigmatal fold l)rowMiish yelloAV. On the anterior half of each segment, in front of 

 the laterodorsal spines of the second to eighth abdominal segments, there is a wiiite 

 spot as large as the bases of the elevations on which the spmes are seated. Spines 

 black thi'oughout, excepting at the extreme base. Avhere, with a part at least of the 

 elevations on which they ai-e seated, they are generally dull orange. Legs black, 

 Prolegs brownish fuscous. Length of body, 8 mm. : breadth of i)ody. 1 .2."i mm. ; length 

 of spines. .oS mm. 



Fimrth stage. Head piceous. scarcely ditt'ering from the previous stage. Body velvety 

 black. The principal spines encircled at their base with orange-ferruginous and the 

 l)osterior half of all the segments traversed by four more or less broken, transverse, 

 slender, white lines, the interspaces betAveeu them being of equal width with these lines. 

 The laterodorsal spines of the abdominal segments, excepting thetii'st, are bordered in 

 front by a round or transversely OAal, conspicuous, white spot. A pair of large papil- 

 lae on the side of the first thoracic segment with one on the side of each of the other 

 thoracic segments amber yellow, furnished with black bristles, similar to those which 

 adorn the jiiceous spines of the rest of the body. The last two abdominal segments 

 with a number of small, white papillae l)earing wiiite hairs. Other hairs of the l)<)dy 

 l)lack. Legs piceous. Prolegs blackish fuscous. Spiracles in the centre livid white; 

 the lips black surrounded by awliite aureole. Length. 12 mm. ; width of head, 1.7.") mm. 



Last staijL' (74:o4). Head (78:60) varying from bronze black to shining piceous, 

 the lai'ger tubercles small and infreciueut, yelloAv or black, the smaller warts not very lui- 

 merous, yelknv or black, bearing short black or yellow hairs, above a little longer. Anten- 

 nae with the first joint obscure, pale, the rest blackish fusccms, annulated at the base of the 

 joints -with pale ; ocelli black ; mouth parts blackish. Body rich, velvety black, broadly 

 banded at the interstices of the segments Avith transverse, alternating, slightly irregu- 

 lar lines of black and pale greenish, straw yellow, or with alternate, broad, transverse, 

 e(|ual bands of black ami greenish yelloAv. streaked Avith black, the former crossing 

 the middle of the segment from spiracle to spiracle ; the space bet.Aveeu the black bands 

 is greenish yelloAv (the yelloAv more conspicuous on the thoracic segments) streaked 

 transversely Avith four or five generally contiiuu)Us but rather irregular equidistant 

 lines of dark, purplish black; the first thoracic segment has no broad, black band , on the 

 abdominal segments, touching the anterior base of the laterodorsal spines and the ante- 

 rior border of the black band, is a row of roundish, silvery Avhite spots, that on the first 

 segment, or first tAvo segments, sometimes minute or smaller than the others, the others 

 large and equal ; behind the black band of the eighth abdominal segment there is a 

 large, transverse, dorsal, dirty Avhite spot, from the outer extremity of which run tAvo 

 similarly colored slightly converging lines neaiJy to the tiji of the ))ody. There is a 

 uarroAv, interi'upted. rufo-fuscous. infrastigmatal band, freciuently obscured by paler 

 markings, and just beneath it a roAV of short, longitudinal, dull orange stripes, situated 

 on the anterior halves of the segments; Ijeneath greenish yelloAv. profusely streaked 

 and blotched, longitudinally on the sides, irregularly ventrally,Avith dark purplish black. 

 Body covered with short and inconspicuous black hairs, those not on the central black 

 l)and arranged to some extent in transverse roAvs ; the spiniform tubercles of the first 

 thoracic segment are very long and pale amber yelloAv. broAvnish or blackish fuscous; 

 the sides of the other thoracic segments have fretpient pale papilliform Avarts, giving 

 rise each to a delicate blackish hair. The spines are very long, the longest nearly 

 e(iuaHing in length the entire Avidth of the head, the apical spinule. or that portion of
