678 THE BUTTERFLIES OF NEW ENGLAND. 



more or less cuneiform cells; the outer, larger and more regularity polj'goual, are 

 about .03 mm. in diameter; those of the central rosette about .0125 mm. long and .0075 

 mm. broad. Color pale lemon yelloAv. Height of egg, .58 mm. ; breadth, .46 mm. ; 

 diameter of summit, .28 mm. 



Caterpillar. First stage (72: 1). Head (79:20) shining blackish brown; labrum 

 pale ; rest of mouth pai'ts dusk^'. Body pale bluish green, dai'kest along a lateral line, 

 the incisures dusky ; the sides tinged with yellow, the first segment with purple ; warts 

 and hairs (86:54) black. Legs black; prolegs dusky at tip. Length, 1.75 mm.; 

 breadth of body, .25 mm. 



Second star/e. Head (79 : 21) uniform blackish brown. Body yellow, with a rather 

 broad, dark brown, lateral stripe, and both back and sides faintly and delicately 

 marked with streaks of yellowisli brown. Hairs black. Prolegs dusky at tip ; legs 

 fuscous throughout. 



Third stage. Head (79 : 22) black, shining. Body yellow, with a slender, dark 

 brown lateral stripe, a dusky dorsal line and numerous transverse, delicate dark 

 streaks ; spines (86 : 55) black, twice as high as broad, with a terminal, slightly bent 

 hair, fully as long as the spine, and frequent shorter, lateral, black spinules, those of 

 opposite sides at rather more than right angles with each other. Prolegs dusky ; legs 

 blackish. 



Fourth stage. Head (79:23) black, shining. Body yellow, with a narrow dorsal, 

 interrupted laterostigmatal and faint stigmatal dark broAvn stripes, with narrow 

 transverse stripes of dark brown nest the incisures; first thoracic and last abdominal 

 segments infuscated. Legs blackish; prolegs dusky outside. vSpines (86:66) yellow 

 at base, Ijeyond black, fully three times as long as broad, regularly tapering, Ijluntly 

 pointed, all the spinules black and of nearly equal length, and aljout half as long as 

 the spine, mounted on little tubercles; spiracles dusky. 



Fifth stage (75 : 13, 14). Head (79 : 24) pitchy black, beset rather sparsely with long 

 and delicate hairs ; antennae and mouth parts black. Body deep orange, the first 

 thoracic segment black specked with orange, the others with the following black 

 markings : a distinct continuous dorsal line ; a transverse sutural line between the 

 segments, often broadening into a transverse dusky patch on the sides ; a submarginal 

 transverse line near the posterior edge of the segments, often broken before reaching 

 the dorsal line, and generally connected with the interstitial line near the spiracles ; 

 a more or less distinct, often nearly obliterated dusky transverse band, connecting the 

 bases of the spines and encircling the spiracles ; and connected with this an inter- 

 rupted, longitudinal, stigmatal line, dusky rather than black; in some more infuscated 

 individuals the transverse bauds and the transverse lines are connected by occasional 

 longitudinal streaks, giving the whole body, or at least the sides, a mottled appear- 

 ance ; in some of these individuals the brighter colors become dimmed, giving a close 

 resemblance to darker forms of E. phaeton. Spines (86 : 57) shining jet black, the 

 needles black. Spiracles black. Legs black; prolegs brown. Length of body, 

 22 mm. ; breadth, 3.5 ram. ; breadth of head, 2 mm. ; length of spines, 1 mm. 



One caterpillar reared by Mr. Edwards in West Virginia was almost black in the last 

 stage, the lighter color being restricted to a few specks and dots on the back of each 

 segment. 



Chrysalis (84 : 17, 18). Snowy white, with a slight tinge of bluish or pale salmon, 

 the abdomen often obscured a little with fuscous. Head with a transverse black band 

 on the front edge, generally passing around the outside of the ocellar prominences 

 a short distance, and at the interior base of each antenna a small black spot ; behind 

 these, along the front edge of the mesonotum, a curving row of four small black 

 spots, two subdorsal and two occupying the prothoracic spiracles; on the summit of 

 the mesonotum a pair of short, slender, oblique, slightly curving subdorsal streaks, 

 the convexity inward and somewhat backward ; tongue black. Legs white, tipped 

 with l)lack ; antennae alternately white and brown tipped with black. Wings with a 

 large, longitudinal, curving, interrupted, mesial, black stripe, tapering at either end, and 

 at. its longest starting from near the base at the lower edge, and terminating near the
