THE BUTTERFLIES OF NEW ENGLAND. 



generally the more distinct, and usually reduced to very short longitudinal lines, the 

 other more cloudy, consistina; of a slightly sinuous series of small, roundish spots in 

 the middle of the outer two-tlfths, occasionally the outer half , of the wing; very 

 rarely one can see very faiut, larger, dusky spots ou either skle of the extra-mesial 

 series ; outer border and fringe as in the fore wing. 



• Abdomen above blackish, the tips of the segments edged minutely with dark gray ; 

 beneath more or less heavily flecked with grayish brown. The abdomen of the female 

 ends in a very bluntly rounded tip, a very little broader than long, and is furnished with 

 very short scales; when denuded, it is seen to be also clothed with very frequent hairs. 

 The appendages of the male (36 : 1-3) have the centrum of the upper organ short, 

 slender, high. Hooks very long and slender, tapering, slightly compressed, separate 

 at base, tuberculate (with one tubercle) externally nest the base, basal halves divari- 

 cate, but beyond subparallel, curving inequally, the tip hooked downward, tapering 

 rapidly and sharply pointed ; from the middle of the ridge which unites their bases, a 

 very miuute denticle depends with a projectiug bristle. Lateral arms broad at their 

 origin, made one-half as small below by an excision of the posterior edge, directed 

 downward and slightly forward, then bent at about a right angle backward, and very 

 soon expanded to a common, very large, spatulate cup, opening upward, its outer half 

 composing the inferior armature of delicate points, widely separate from the base of 

 the terminal hooks. Left clasp : Main body nearly triangular, the apex at the poiut of 

 attachment, widening rapidly, a little curved longitudinally and slightly gibbous later- 

 ally. Blade very loug aud slender, the basal fourth rapidly narrowing, beyond nearly 

 equal, depressed, curving inward, at first slightly, afterwards rapidly, so as to be sub- 

 falcate; otherwise nearly straight ; tip produced to a sharp poiut ; Ijasal process con- 

 sisting of a gibbous5subreniform lobe, not half so long as the blade, constricted at the 

 base, having a general backward direction, curved a little inward, its upper margin 

 strongly arched, its lower excised, rounded at the tip, the basal portion of its lower 

 margin bent inwards and forming a slight, sharp, inconspicuous ridge. Lobe large, 

 broad, uniform in width, as long as the basal process of the blade and twice as broad, 

 directed backward, somewhat upward and a little inward, its outer surface turned 

 slightly upward, its apex rounded aud curved slightly inward. Bight clasp : Maiu body 

 much as in the opposite clasp, but baring a broad angle near the middle of the upper 

 margin, beyond which it does not broaden; it is also more deeply excised ou the lower 

 margin. Blade as long as that of the left clasp, narrowed at the base and beyond de- 

 pressed as there, but just beyond the middle it is bent slightly downward, and has its 

 upper margin slightly angulated, or is at least curved a little downward in the outer 

 half; close to the tip the inner edge is angulated again, broadening the tip, which ter- 

 minates in a rounded right angle; basal process consisting only of a small, triangular, 

 rounded, backward prolongation at the extreme base of the upper edge of the blade. 

 Lobe extremely broad aud large, half as long as the blade, angulated in the middle of 

 its lower margin, its upper half produced as a narrowing rounded plate, curved 

 strongly over upon itself, tlie concealed margins armed with a few rather prominent 

 spinules.

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

 closes a mass of clustered pediform bristles (47 : 3 a) about .75 mm. in length; scaphi- 

 form androconia (3 b, e) of varying lengths rarely so little as twice as long as broad, 

 found on the costal 'vein ; and stout, rod-like androconia (3 c, d) of varyini; length,
