838 I'lIIC lUTTEllFUES OF NEW ENGLAND. 



or lilaceous scales more sparsely scattered than In the suflVised belt and enlivened in 

 the lower median interspace by the normal dark si)ot of this place which falls in its 

 niidiUe. The wiiii;s extend 30 mm. 



Secondary sexual peculiarities. Tlie discal stigma of the male is described 

 umlcr tlic fore wiii^'. The scales which occur there (46 : 25) are pretty large, quad- 

 r.mi^tilar. al)out four times as long as broad, the apex truncate with rounded angles, the 

 base faintly lobed. 



Egg (65.11, 10). Shell very thin, shining and smooth, ornamented with very high 

 ridges, arranged witli some regularity; where they cross each other thickened, form- 

 ing stellate, six-rayed prominences ; the lines connecting the extremities of the rays 

 form regular hexagons, .11 mm. in breadth; the thickened centres are .03 mm. in 

 diameter and at least .02 mm. high; the connecting lines are delicate, straight and less 

 elevated than the centres; the cells are arranged in rows, one of which is nearly hor- 

 izontal, .and the others divide it at opposite angles; above, the ridges diminish in 

 height .and regularity, leaving, next the centre of the summit (68 : 8) a space compar- 

 atively smooth. Micropyle rosette .19 mm. in diameter, the cells nearly circular, but 

 angular and averaging .0234: mm. in diameter; the central one circular, .017 mm. in 

 diameter, and surrounded by six circular cells of nearly the same size. Color very 

 deep green, the elevations pale green. Height, .3 mm. ; breadth, .62 mm. 



Caterpillar. Mrst stage. Head (79 : 42) pale yellowish, ocellar field large, round, 

 black. Body very pale greenish yellow, the dorsal hairs provided with excessively 

 minute spicules, which on the same side are a little further apart than the width of 

 the hairs; spiracles brownish with a whitish annulus in the middle; hairs colorless, 

 dusky at the very base, the short bristles of the laterodorsal row dusky, tipped with 

 black. Length, 1.25 mm. ; breadth of head, .25 mm. ; length of dorsal hairs, .3 mm. ; 

 basal breadth of same, .OOfi mm. 



Second stage. Head yellow green. Body dull yellow green on dorsal area with a 

 dorsal red brown stripe reaching to the eighth abdominal segment ; sides red brown, 

 limited above by a macular brown line at the outer edge of the dorsal area, and with 

 an infralateral (?) yellowish line; substigmatal fold yellowish; under surface yellow 

 green; upper surface with many short, stifl', brown hairs. Length, 2 mm. (After 

 Edwards.) 



Third stage. Body red brown and dull yellow green; a red dorsal band, tapering to 

 a point beliind, with a mediodorsal green line; rest of dorsal area green, but iuclnding 

 a little red brown space on each segment ; sides red brown, with a green infralateral ( ?) 

 line; substigmatal fold green. Length, 3 mm. (After Edwards.) 



Last stage (75 : 22, 23, 28). Head yellow green. Body with the dorsal area yellow 

 green, the lateral red brow'n with an infralateral (?) indistinct green line; substigma- 

 tal fold green. Body covered with short, brown hairs. Subsequently, shortly before 

 pup.ation, the general color changes to port wine-red, but with the laterodorsal ridges 

 yellow green, tinted posteriorly with red on each segment; a pale red line along sub- 

 stigmatal fold. Length, .13 mm. (After Edwards.) 



Another specimen, confidently presumed to belong to this species, was "yellow green, 

 yellow predominating on the sides; the dorsal elevations have the summits yellow, 

 the outsides greenish; the mediodorsal stripe green, edged on either side by a brown 

 line" (Edwards). 



Chrysalis (84:20,32-34). "Black or brown black with obscure red bands ; there 

 being on either side a narrow black stripe in the middle of the abdomen; a mesono- 

 tum this stripe disajipears and the red remains" (Edwards). 



Distribution (23 : 4). This butterfly is also a member of the Allegha- 

 nian fauna, but unlike the other species of Incisalia it is more abundant 

 southwardly, not occurring at all in eastern Canada and extending to 

 the Ogechce Swamp in Georgia (Abbot) where, however, it is "far from
