524 THE BUTTERFLIES OF NEW ENGLAND. 



and edged throughout, above and below, with an unequal black line; extreme base of 

 legs and prolegs with a similar black-edged Avhite line, those of the prolegs broken in 

 the middle and each part oblique, the lower edging merging into the black of the mem- 

 bers: spines black, the anterior subdorsal pair of the latter longer by about two- 

 thirds than the others of the same row- Length, 23 5 mm ; breadth, 3 mm. ; length 

 of anterior spines, 3 mm. 



The above are described from colored drawings in Mr. W. H. Edwards's possession. 



Last stage (75: C}, 7). Head (79:1) shining blackish purple, the summit, the tri- 

 angle and the borders of the same pale reddish orange ; a reddish streak through the 

 ocellar field ; basal joint of antennae pale, terminal blackish; ocelli black, the upper 

 one reddish, and the others sometimes f aintl}' tinged with the same ; labrnm pale, man- 

 dibles black ; labial palpi pale, somewhat annulated Avitli blackish. 



Bod.v reddish orange, with bi'oad laterodorsal and suprastigmatal black bands ; the 

 former encloses white spots, variable in size and arrangement, but generally quadrate 

 and placed along the middle ; the latter encloses along its lower portion much more 

 frequent, almost connected, generally transversely quadrate, white spots; there is 

 also a narrower lateroventral, irregular, tortuous band of whitish, and a single longi- 

 tudinally ovate dorsal spot of white encircled with black on each segment, the 

 abdominal ones much the largest ; under surface of body reddish, infuscated ; Avhole 

 surface of the body covered with inconspicuous, short, very delicate, distant, blackish 

 liairs, surmounting minute, speck-like, black warts ; spines black or steel-blue ; spiracles 

 .black. Legs exceedingly dark metallic green, with long, delicate hairs ; prolegs reddish 

 ^nfuscated, the apical portion metallic green, the whole covered with long, delicate, 

 blackish hairs; length of body. 30 mm. ; of anterior spines, 7 mm. ; of other spines, 

 2.75 mm. ; breadth of body, 4.5 mm. ; of head, 2.6 mm. 



There is considerable variation in the color of this striking caterpillar ; the two 

 figures which we publish show this. One drawing by Abbot represents the ground 

 color as dull cinnamoneous, the longitudinal stripes and blotches nearly white, the 

 spines dark brown. 



Chrysalis (84 : 8, 9). Silvery white marked with black, all the tubercles gilt witli 

 their posterior faces sometimes silvery. Summit of the head between the bases of 

 the antennae with a small black spot in front, joining a double black spot on the upper 

 portion of the front, and next the posterior base of the antennae a small spot on either 

 side. Labrum and all the parts below it, together with the tongue, and a large oval spot 

 running np the inner front of each ocellar prominence which encloses a luteous blotch, 

 black ; angular border of the tongue-base luteous ; summit of the eye with a longi- 

 tudinal dash of black ; the ocellar ribbon luteous, edged broadly over most of either 

 side wnth black. Antennae yellowish with the division of the joints marked rather 

 broadly witli fuscous, at base, where the joints are slaort, confluent, and deepening into 

 black, and on the club broadly confluent along the median line; extreme anterior 

 base of first joint black. Legs over the anterior half silvery, marked with a 

 few moderately large, black blotches ; on the posterior half mostly black. Wings 

 marked broadly with black, never extending upon the nervures ; a broad inferior border 

 of black, interrupted in the middle, and two very large, longitudinal blotches, broadly 

 divided by luteous at the nervures, and having some outlying spots in close connection : 

 one shorter, occupying the posterior third of the wing in its length and the middle of 

 the lower half in its breadth ; tlie otlier, the posterior half and the middle of the supe- 

 rior two-thirds; the superior face of the projecting part of the wing is marked with 

 black and luteous. Thorax marked witli a considerable number of small, round, black 

 spots, confluent in front of tlie tubercles and encircling them with black excepting 

 posteriorly, on the two hinder segments bordering tliem only on the inner front on the 

 prothorax ; on the posterior edge of the abdominal segments is a transverse row of 

 small black spots arranged for the most part in a laterodorsal (at the upper edge of 

 the tubercles), alaterostigmatal, suprastigmatal, and stigmatal series, besides a ventro- 

 stigmatal one ; besides these there is a subdorsal series in the middle of the segments 

 and a laterostigmatal both in the middle and on the anterior border of the segments ;
