THE BUTTERFLIES OF NEW ENGLAND. 



the subcosto-median interspace iiulistiuctly broken by the longitudinal fold in the 

 middle of the interspace, the other two in the median interspaces, the lower having its 

 outer edge at the centre of the interspace ; the fringe is uniform pale honey yellow, 

 partially covered on basal fourth with brownish fuscous, the whole partially obscured 

 by fuscous along the inner margin. 



Beneath, dull snuff brown, the disc of the fore wings, from the upper limit of the cell 

 to the inner border and reaching so far as to include the outer of the large vitreous 

 spots and from thence do\ynward to the tip of the inner margin, brown, darker in the 

 middle of the wing. Fore wiiifjs with the same vitreous spots as above, a little more 

 distinct; fringe nearly uniform -with the neighboring parts of the wing, the apL»x 

 above the lower median nervnle tipped with brown. Hind wlnys uniform, with the 

 same vitreous spots as on the upper surface, the upper more distinctly divided. Fringe, 

 with the basal one-third of the portion above the lower median nervule and the whole 

 of that along the inner margin of the color of the wing, the rest partaking more of 

 the color of the upper surface of the fringe. 



Abdomen above dark brown, covered with many fulvous hairs ; beneath pale yel- 

 lowish white, interrupted by trausverse, indistinct bars of brownish fuscous, near the 

 bases of the segments ; clasps of male furnished with yellowish hairs. The upper orgau 

 of the male appendages (37 : 34) has the hook scarcely longer than the centrum, taper- 

 ing regularly and rapidly to a blunt point ; basal half with a heavy compressed ridge ; 

 lateral arms smaller than the hook and curved a little in a reverse sense. Clasps with 

 the inferior margin slightly and roundly excised near the middle, the posterior margin 

 neai-ly straight and the upper posterior angle produced to a small laminate and tri- 

 angular tooth, a little incurved. 



FEMALES. 



Egg (66:34). The cells at the extreme base of the egg are about two and a half 

 times broader than long ; and a short way above they are mostly of equal height and 

 breadth, sometimes perfectly square, but usually irregular, quadrilateral, lozenge- 

 shaped or pentagonal, above usually pentagonal but very irregular; where they 

 average of an equal diameter they are about .03 mm. in breadth; the surface of the 

 cells is shallowly, uniformly and rather closely punctate, the punctae about .005 mm. 

 in diameter, numbering about twenty-five to thirty in a cell, ranged in tolerably 

 straight rows ; the micropyle (69:15) consists of about seven kite-shaped cells ar- 

 ranged symmetrically round a central circle and entirely free of the punctae ; the cen- 

 tral circle is about .007 ram. in diameter, the kite-shaped cells are about .015 mm. in 

 their longer axis, and the whole circlet of cells about .035 mm. in diameter; this 

 circlet is immediately followed by cells about .025 mm. in length and about .02 mm. 

 in breadth. Height of eg;i, .68 mm. ; diameter, 1.25 mm. 



Caterpillar. First stage. Head piceous with very faint, transverse punctae or 

 short striae very slightly impressed; mouth parts fuscous. Body pale yellowish 

 brown; dorsal thoracic shield blackish; anal plate edged with luteous; bristle pel- 

 lucid, those of the last abdominal segment fuscous ; thoracic legs testaceous, all the 

 pairs alike; prologs concolorous with the body; booklets testaceous. Length of 

 body, 3.5 mm. ; breadth of body, .5 mm. ; of head, .7 mm. Described from speci- 

 mens preserved in glycerine. 



Second stage. Head uniform yellowish brown, the surface delicately reticulate with 

 blackish fuscous, forming very small angular cells; the triangle free from them and 

 somewhat lighter in color; ocelli pellucid with a blackish annulus at the base of each. 

 Body dirty yellow, somewhat infuscated along the sides, flecked with dull fuscous, 

 minute papillae sparsely scattered over the body, supporting minute, excessively short,
