THE BUTTERFLIE.S OF NEW ENGLAJS'D. 



the ground color on either side of the lowest subcostal nervule, commencing at the out- 

 side of the lower eslremity of the .sul)apical spots ; edge of outer border narrowly 

 marked with a dusky or blackish line ; fringe much as above, but with the darker mark- 

 ings intensified, and sometimes with the extreme base aflected by the hoary suffusion 

 of the neighboring parts. Hind loings mostly of the tint of the outer half of the fore 

 wings, crossed by two distant, not very broad, equal, often inconspicuous, tremulous 

 bands, subparallel to each other, aud the outer border a little darker than the ground 

 color of the wings, but with all, excepting the edges, flecked with whitish scales or 

 paler than the ground color of the wing ; the inner band runs from the middle of the 

 basal four-fifths of the submedian nervure to the divarication of the subcostal; It 

 crosses only the costo-subcostal interspace by two distant, parallel bars, at equal dis- 

 tances on either side of wh.at would be the continuation of the band, aud entirely sepa- 

 rate from it; the outer band lies al)out midway between the inner one and the outer 

 border, is more tremulous in its course, its edges being sometimes almost zigzag; be- 

 yond this, tliewhole wing is always to at least a slight degree paler, and is often very 

 considerably hoary, forming a iielt which has its influence on the coloration of the up- 

 per surface of the wing ; this hoary, pretty uniform flecking is similar to that of the 

 outer border of the fore wing, and like that is more profuse and common in the ? 

 than in the (J , and in northern than in southern specimens ; sometimes when the 

 hoariness is comparatively slight, it is also confined to the outer half of this belt, and 

 is then sometimes vaguely bordered by a dusky, arcuate margin, which runs from 

 the tip of the costal to the tip of the lowest median nervule; hoary scales are 

 sometimes found scattered sparsely all over the wing ; the outer margin is narrowly 

 edged with a blackish liue, which, as well as the extreme base of the fringe, is some- 

 times obscured by the hoary fleckiugs ; fringe a little paler than above, bringing the 

 darker markings into a more distinct relief, but otherwise similar. 



Abdomen blackish brown, above sparsely flecked, especially toward the base of the 

 joints, with yellowish scales; beneath, similar, but with more aljundaut flecking; tips 

 of the scales at the very apex of the body faint, dull, olivaceous bufl'. Upper orgau of 

 male appendages (35 : 35) with the hooks as large as the centrum, rather widely sepa- 

 rated, parallel and straight, the tip slightly uncinate beueath ; lateral arms reaching 

 beyond the middle of the apical half of the hooks; clasps more than twice as long as 

 broad, the basal half equal, the middle of the upper edge with a slight, angular projec- 

 tion, the upper lobe marked by an oblique notch directed backward, one-fourth the 

 depth of the width of the clasp at this point ; beyond this the clasp is but one-half its 

 original breadth, rounded at the tip. but above inconspicuously biscuspid. 



Described from 93 ^ , 43 9 . 



Accessory sexual peculiarities. The costal fold of the fore wing of the male 

 encloses many chaiu-l)ristles, with apical flagellum and composed generally of about 

 half a dozen links, each about .058 mm. in length (48 : 3b) ; a great number of minute, 

 peg-shaped bristles (48 : 3c) , a little and very broadly constricted mesially, of varying 

 lengths, but rarely as long as one of the links of the chain-bristle; and many slender, 

 lanceolate, but apically rounded blades (48: 3a), nearly or quite as long as the chain- 

 bristles, apparently with a granular structure, but with the granulations elongate and 

 longitudinal, giving the appearance of weakly interrupted, longitudinal canals. 



Malformation. In one specimen before me there is a malformation in the antenna, 

 an additional wedge-shaped, minute joint being forced in between two others at the 

 very base of the club on the inferior surface; it is not apparent above. 



Egg (66 : 7). Fifteen vertical ribs, rather delicate, sharply defined, scarcely reach-
