138 THE BUTTERFLIES OF 'SEW ENGLAND. 



next sta<>-e ; labrnin ecliied with blackish castaneoiis. Ocelli black. Antennae beyond 

 basal joint fnlisiinons. Body very pallid bro-\vnish green beneath, sharply detined at 

 the infrastigmatal line from the upper coloring, and carrying Avith it the color of the 

 legs and prolegs. The whole effect of the npper part of the body is more pallid than 

 beneath, but it is made up of a series of bands of which a A'ery broad dorsal one and 

 a laterostigmatal (and especially the latter) are nearly the color of the under surface 

 and have in addition an interrupted black edging (the latter only above), leaving 

 broad stigmatal and lateral bands of a strikingly pallid hue (the interruptions as in full- 

 groAvn larva). Besides there is a narrow, interrupted, black dorsal stripe and the stig- 

 mata are black. The whole body is besprinkled with brownish papillae bearing short, 

 recumbent, club-shaped, testaceous hairs no longer than themselves. Length 12 mm. ; 

 width of head 2 mm. 



Last stage. (74 : 2, 4, 15) . Head (78 : 8) brownish yellow or dull greenish brown . with 

 seven bands of black or fuscous spots, situated on the prominences, one median, the 

 others disposed in pairs ; the median is l)road and continues half way down the suture 

 of the triangle ; the next is parallel to it, of equal length, slightly narrower, separated 

 by its ownwadth from the median; the succeeding is slender and short, consisting 

 of only ten or twelve black dots placed on the middle of the sides and having a hori- 

 zontal direction ; at right angles to this is the last, arising just in front of the base of 

 the front legs, as short as the previous, still smaller and running at right angles to it; 

 the punctulations are brown ; there is a dark dot just behind and on a line with the 

 anteniuie; sutures of the triangle dark ])rown. First joint of antennae dusky, second 

 black, third reddish brown. Ocelli black, excepting the uppermost, which is reddish 

 brown. Labrura black. Mandibles reddish, black-tipped. Maxillae dusky, the ter- 

 minal joint darkest. Labium dark brown. 



Body dirty yellowish green, furnished above with : lirst, a rather narrow black medio- 

 dorsal stripe, enclosing, on the apical half of each segment, little, rather pale green, 

 longitudinal spots or dashes, those of the thoracic segments uniting to form a narrow 

 line; the band tapers at either end of the body; second, a narrow, interrupted, inky 

 black, supralateral stripe, composed of oblique dashes situated principally upon the 

 anterior portions of the segments, the anterior extremities directed downward; third, 

 a narroAV, dark green, siiprastigmatal stripe of the same ividth as the supralateral 

 stripe, edged superiorly Avith inky black, which is slightly diffused downward at the 

 base and apex of each segment, especially of the abdominal ones. The space between 

 the stripes is pale yellowish green, tinged with faint reddish brown at the apical half of 

 each segment, and on the sides also considerably tinged with reddish brown ; below the 

 suprastigmatal stripe, the sides are grass green with a flush of roseate, sometimes 

 with an inconspicuous pale inf rastigmatal line ; the under surface is uniform pale grass 

 green ; the papillae with which the body is covered are pale and the hairs they emit dark 

 reddish. Spiracles black. Legs dusky; prolegs of the color of the under surface. 

 Length, 23.5 mm. ; greatest bi'eadth of body, 5.5 mm. ; of head, 2.5 mm. ; of mediodor- 

 sal stripe, .375 mm. ; of space between mediodorsal and supralateral stripe, .875 mm. 



Chrysalis (83:4,5). Dull yellowish brown, the head, the thorax, excepting a fine 

 dorsal line, and the middle of the wings, obscured by brownish fuscous ; tongue, sum- 

 mit of head and veins of the wings blackish fuscous. Abdomen furnished Avith several 

 roAvs of transversely OA'al or roundish, broAvnish fuscous spots, two on a segment, 

 placed at equal distances from the anterior and posterior borders, and, usually, from 

 each other ; on either side is a laterodorsal roAV, Avhere the spots are placed in a straight 

 line and the roAv is lengthened by a single spot upon the metathorax; a lateral roAv, in 

 Avhich the posterior spot of each segment is placed beloAvthe anterior by nearly or quite 

 its oAvn length and is besides longer than the others; a laterostigmatal roAV, similar to, 

 but usually not so conspicuous as, the lateral roAv; anterior to and a little beloAv the 

 posterior spot on each segment in the laterostigmatal series is a similar, slightly larger 

 spot, most conspicuous on the anterior segments ; an infrastigmatal series of similar 

 spots, placed in a line and frequently confluent, or the anterior absent; beneath these 

 is a medioventral band of fuscous dots and streaks ; and at equal distances between this
