1116 THE BUTTERFLIES OF NEW ENGLAND. 



and equally prominent throughout; in the middle of the egg, they are, at most, .065 

 mm. apart ; tliey reach but do not pas.s the delicately thickened rim of the summit ; 

 cross lines, .0127 ram. apart; surface granulated or crowded with low warts. Mlcro- 

 pyle rosette (68: 14), .07G mm. in diameter; the oval cells .0115 ram. long and .0084 

 ram. broad ; the other cells roundish but angular, averaging .015 mm. in diameter; 

 bounded by scarcely raised, coarse lines, rendering the whole very obscure. Color 

 when tlrst laid whitish, sliglitly tinged with pale greenish yellow; in forty-two hours 

 they become pale salmon coloured ; when fifty-six hours old they are bright reddish 

 orange, yellowish in the slenderer parts, a color which they retain until shortly before 

 hatching, when they turn to a plumbeous hue. Height, 1.24 mm. ; greatest breadth, 

 .44 mm. ; breadth at base and summit, .1 ram. 



Caterpillar. First stat/e (72:3). Head (79 : 4f>) shining plceous ; papillae and hairs 

 pellucid. Body dark yellowish brown with a faint, dusky, delicate, dorsal line, the 

 segments tinged, especially on the anterior part of the body, with reddish, the raised 

 points fuscous and very regularly distriljuted. Papillae fuscous; hairs pellucid, wine 

 glass shaped, expanding greatly, being as broad at summit as the length and l)ut little 

 longer than the tubercle upon which it is seated, the lower ones changing to a club 

 shape, being rounded and less expanded at the tip. Spiracles fuscous. Legs of the 

 color of the body, tipped with black. Length of body, 1.75 mm. ; of papillae of body 

 including wart, .03 mm. ; of hairs of first segment, .09 mm. ; of papillae of head in- 

 cluding wart, .04 mm. ; breadth of body, .3 mm. ; of head, .32 mm. 



Second stage. Head uniform grass green with a yellowish tinge with scattered' 

 blackish fuscous dots, each bearing a short, pale hair; ocelli black, tipped with 

 greenish. Mandibles reddish black. Body nearly uniform grass green with a narrow, 

 faint, dusky, dorsal stripe, a similar lateral stripe and a pale, stigmatal band ; first tho- 

 racic segment with scattered, blackish fuscous dots, each giving rise to a short, pale 

 hair; each of the five divisions of the segments supports a transverse row of eight 

 minute, pale, fuscous tipped warts each giving rise to a short, pale hair. Length, 5.5 

 mm. ; breadth, 1 mm. 



Tliird stage (79: il). Tlie colors remain unaltered. Specimens in the second and 

 third day of this stage measured 8.5 ram. long and 1.5 rara. broad. 



Fourth stage. Head grass green, sprinliled with pale dots from which short, black- 

 ish and whitish hairs arise; ocelli black, tipped witli green; mouth parts green, the 

 mandibles tipped with reddish fuscous. Body uniform grass green above and below; 

 a faint, narrow, darker green, dorsal line, which is simply tlie indication of tlie dorsal 

 vessel; a stigmatal, pale roseate band, a little broader than the length of the spira- 

 cles, scarcely reaching their lower extremity and extending some distance above, passes 

 along the whole body excepting tlie tip of the last segment ; whole upper surface pro- 

 fusely sprinkled with pale wartlets, arranged pretty regularly in transverse rows but 

 irregul.arly in longitudinal ones, each emitting a shoi-t blackish or whitish hair; on the 

 under surface less regularly disposed. Spiracles green witli whitish lips. Legs green, 

 tipped faintly and slightly with fuscous. Prolegs green. Length, 14.75 mm. ; 

 breadth, 2.5 mm. 



Last stage (76 : 10; 79:48). Does not dift'er from the preceding stage, ))ut shows 

 some variation in the stigmatal stripe, whicli sometimes may be found in part at least 

 in the previous stage. This band is sometimes whitish or only very slightly tinged 

 with rosaceous and is occasionally inteiTupted with rosaceous in the middle of each 

 segment, or it may have a delicate, uninterrupted, red line passing through the lower 

 part of it, tliat is, through the centre of the spiracles; sometimes also, and especially 

 where the stigmatal band is interrupted witli rosaceous, there are, immediately l)elow 

 the rosaceous spots, that is, midway between the spiracles and the posterior border of 

 each segment and usually occupying about one-third of that space, bordering the 

 lower margin of tlie stigmatal band and usually about half as broad as it, patches of 

 black, usually oblong ovate in shape, but sometimes crescentic. I have also seen speci- 

 mens in which there were faint indications of an obsolete, lateral line in the presence 

 of a few pink and white dots linearly .arranged. . Length, 28 mm. ; breadth, 4 mm.
