THE BUTTERFLIES OF NEW ENGLAND. 



by the orange patch, narrowly bordered by scattered blackish scales, which are col- 

 lected at the uervnle tips into blackish spots, sometimes nearly or quite connected, 

 and generally more conspicuous in the male than in the female; tip of the lower 

 median and sometimes of the subraedian nervnle dotted with black ; fringe pale green- 

 ish yellow, broadly interrupted with black next the black markings. Hind tcings : 

 fringe whitish, narrowly interrupted with black at all the nervnre tips, where the 

 black occasionally infringes, in the least possible degree, upon the wing itself. 



Beneath: fore wings white, the outer edge faintly tinted with greenish yellow, the 

 spot at tip of cell and the markings on the basal half of the costal margin as on the 

 upper surface ; tips of all the nervules, equally on the costal and outer border, marked 

 by a small triangular, black spot, mostly made up of the fringe; apex, over nearly all 

 that portion, which, in the male, is occupied above by the orange patch, covered with 

 an irregular flecking of dark brown scales, occasionally obscurely clustered ; fringe as 

 on the upper surface. Hind wings white, the outer border slightly, and the veins 

 still more slightly, snfl'used with a greenish yellow tinge, and the whole surface pro- 

 fusely sprinkled with light brown and blackish brown scales, never compacted in solid 

 masses, but collected iu open clusters, scattered over the whole wing, the darker scales 

 mostly confined to the basal half, the lighter to the apical half of the wing; the 

 darker ones are mostly arranged in straggling, transverse, peppery patches and 

 streaks, the paler ones in broad, dusky blotches, following the nervules ; there are 

 also some open white patches, in particular three irregular, generally quadrate ones, at 

 equal distances along the costal border ; a long streak follows the middle of the cell 

 and extends a little way beyond it, partially interrupted in the middle from the inner 

 side, and just beyond receiving a diagonal patch on the same side; smaller, irregu- 

 larly longitudinal, inconspicuous patches occur just above the middle of each of the 

 subcostal and median interspaces, and an inconspicuous one is found in the middle of 

 the medio-submedian interspace, at the first divarication of the median nervnre ; fringe 

 and spots at tip of the nervules as on the upper surface. 



Abdomen black above, flecked with a few white scales and long, delicate, bluish 

 hairs ; beneath wliitish. Upper organ of male appendages (35 : 14) not quite reaching 

 the tip of the clasps, the hook as long as the centrum, tapering rapidly on its basal 

 half, beyond but little, pretty strongly arclied and pointed. Clasps more than twice 

 as long as broad, tapering and rounded at the extremity, the apical upper portion 

 curved slightly inward, the upper edge a very little concave. 



Accessory sexual peculiarities. Besides the striking differences between the 

 sexes in the coloration of the tip of the fore wing above, the males have scattered 

 over the wing androconia (46 : 41) of a very distinct type, formed of a simple lamina 

 with scarcely convex sides, a little more than twice as long as broad, the base abruptly 

 tapering to a slender pedicel, the apex broadly and angularly rounded with a dense, 

 short fringe, tlie filaments enlarged apically and as numerous as the flne and crowded 

 striae of the lamina. 



Egg (65 : 29). Two and a half times higher than broad, the middle third of nearly 

 equal breadtli, with thirteen to fifteen vertical ribs of which only seven or eight re.ach 

 the summit ; cells about three or four times broader than long. Color varying from 

 faint to deep orange. Height, .95 mm. ; breadth, .38 ram. The figure on the plate is 

 not slender enough. 



Caterpillar. First stage (73 : 9). Head very pale smoky green, the hinder edge 

 margined very narrowly with black; a few short bristles crowded on papillae scat- 

 tered sparsely over the front ; labrum pale. Body dull amber yellow, a little infus-
