THE BUTTERFLIES OF NEW ENGLAND. 



naked aud ferrugiuo-testaceous ou the inner lower side, the apical joints wholly 

 naked, yellow luteous, slightly infnscated apically. Tongue light castaneous at base. 

 Thorax covered above with silky hairs which are dark green olivaceous changing to 

 golden brown, beneath with mingled hoary and vino-ferruginous hairs. Fore legs 

 with similar hairs, the front of the tibiae with a median stripe of rich, black-brown 

 scales flanked by silvery white scales. Other femora black-brown, heavily flecked 

 with silvery gray within and' with ferruginous without; tibiae and tarsi hoary white, 

 the former, along the middle above, and especially on basal half, marked with black- 

 brown. Spines black; spurs and claws dark castaneous, the latter tipped with black; 

 paronychia dull luteous ; pulvillus black-brown. 



Wings above of precisely the same colors and pattern as P. f annus upon both wings , 

 though in general it is slightly smaller. Fore loings with the upper portion of the 

 outer border slightly concave, the dentation nearly rectangular ; that at tip of lower 

 median nervule rather prominent, strongly rounded ; outer margin slightly creimlate. 

 Hind wi7igs (61 : 22) with the outer border considerably creuulate, the tail of the upper 

 median longer than broad, tapering ; the projection at the tip of the upper subcostal 

 large, broad, including the middle subcostal and well rounded, that at the loAver angle 

 considerable, well rounded. 



Beneath the contrasts are striking. The sexes agree in coloration. The basal half 

 of the wings, separated from the apical portion by a line of demarcation which follows 

 exactly the same course as in f annus, is of a very dark brownish ferruginous, deepening 

 outwardly, while the outer half of the wing, excepting the markings of the outer 

 margin, is hoary almost to Avhiteuess, crossed especially next the mesial band by short 

 dusky threads. The markings of the base of the fore wings are the same as those of 

 faunus, and those of the apical half of the wing are also the same, excepting in the 

 almost total absence of green scales from the submarginal lunules, which are here 

 generally distinct and much smaller, never forming a common broad lunule; the 

 Interior arcuate series of green spots is supplanted by a row of inconspicuous black- 

 ish dots and the whole outer margin is unsupplied Avith any excepting the faintest ochre- 

 ous colors, the apex being gray. On the hind wings the central C forms a well bent L, 

 the longitudinal limb seldom more than half as long as the transverse, and both, but 

 especially the lower, tapering toward their tips ; while, as in the fore wings, the arcuate 

 series of greenish spots is reduced to a row of inconspicuous black dots, and the sub- 

 marginal lunules are but slightly provided with enclosed greenish lunules, though more 

 green is to be seen than on the fore wings ; ochreous colors are also wanting along the 

 outer border, which is colored more as in progne, being as dark or nearly as dark 

 as the base ; the inner border is more distinctly ashen than in faunus outside of the 

 series of deep loops of black threads, which ornament this part of the wing in this 

 species. 



Abdomen above with mingled black and dark orange ferruginous scales, beneath 

 gray with mingled vino-ferruginous and hoary yellow scales, the last two joints with 

 dark slate brown scales. Appendages of the male (33 : 21) : upper organ precisely as 

 in progne, or a trifle slighter only ; clasps with the main body the same as in progne, 

 but a little narrower above, the basal process of upper margin slighter than in progne, 

 more depressed and more pointed; interior flnger the same, but with the incurved 

 apical portion proportionally longer.
