NYMPllALiXAE : RJLYGONIA TROGXE. 363 



or tawny, the apex of the .superioi" fringe and the base of the inferior fringe narrowly 

 whiti.sli, and a median longitudinal paler streak, in continuation of the white parts of tlie 

 base of the palpi; the hairs l)lack; beneath, the white inferior fringe is seen to have a 

 very broad median stripe of blackisli and feiTuginous scales. Antennae very dark 

 brown above, lightly llecked with paler and toward the tip of the stalk with hoary 

 scales, especially at the base of the joints ; beneath, inwardly naked and pale luteous ex- 

 cepting near the base, where it is white outwardly with a broad patch of white on 

 the basal half of each joint, attenuated toward the tip but toward the base of the club 

 forming a more or less connected stripe ; club dark brown above, flecked at base with 

 whitish, beyond with ferruginous scales ; beneath, fuscous, the apical three or four 

 joints wholly pale luteous. Basal third of tongue luteous, beyond brownish fuscous, 

 the tip luteous again. 



Thorax covered above with olivaceous, beneath with dark chocolate, hoary -tipped 

 hairs. Fore legs with a stripe of l)lack scales down the front, l^ordered externally with 

 white, internally with mingled white and fulvous scales, and fringed on eitlier side with 

 mingled dark vinous and hoary hairs ; femora of other legs gray with an intermingling 

 of black and white and some colored scales, at the tip yellowish, beneath with a line 

 of black scales inwardly ; tibiae and tarsi hoary white mingled with pale brown 

 scales, the tibiae often tinged with yellowish and with a broader or narrower dark 

 brown stripe down their front ; spines blackish castaneous ; spurs dark reddish, paler 

 at base, blackish at apex. Claws dark reddish, darkest at tip; paronychia pale; 

 pulvillus black. 



Wings above fulvous orange often quite pale, almost always deeper on the basal 

 fourth of the wings. Fort loings with the upper portion of the outer border slightly 

 concave, the dentation nearly rectangular and blunter than in the other species, that at 

 tip of lower median nervule not very prominent, broadly rounded, outer margin 

 scarcely crenulate. The costal edge obscure, throughout marmorated with blackish and 

 dull greenish yellow; in the middle of the cell are two small, oblique, subovate spots, 

 the upper, more nearly transverse than longitudinal, depending from the subcostal 

 nervure just beyond the emission of the first nervule, is directed inward; the lower, 

 often almost circular and more nearly longitudinal than vertical, is of the same size as 

 the upper, placed midway between it and the median nervure, its innermost extremity 

 lying just above the base of the first median nervule ; the extremity of the cell is marked 

 hy abroad, transverse, black bar, twice as broad above as below, and partially obscured 

 by au admixture of tawny scales ; it reaches from the costal margin to the median nervure, 

 touching the latter only by its inner angle, its interior margin concave and best defined 

 below the base of the lowest subcostal nervule ; on the subcostal nervure its breadth 

 reaches from the base of the first inferior to that of the third superior subcostal 

 nervule ; in the median and medio-submedian interspaces is a nearly straight series of 

 three subequal, roundish, vaguely defined, blackish spots, that in the upper median 

 interspace generally a little smaller than the others, the largest seldom more than 

 equalling half an interspace in width, the upper one placed just before the middle of 

 the upper median interspace, all at an equal distance from the median nervure ; 

 depending from the costal border, midway between the transverse mesial bar and the 

 apex of the wing, is a second transverse, subtriangular, dusky patch, more or less, and 

 nearly always considerably, tinged with ferruginous, especially externally ; it is parallel 

 to the transverse mesial bar, tapers downward and reaches the upper median nervule, its 

 outer border passing a little beyond the last divarication of the subcostal, and has 

 throughout vaguely defined borders, the lower portion being genei'ally clouded and 

 sometimes obsolescent; the outer border is very broadly margined, nearly to the 

 depth of an interspace's width, with blackish, and above tlie subcostal angulation 

 broadens as it approaches the costal border, so as to leave but a narrow space between 

 it and the subapical, transverse blotch; this margin is directly followed in the inter- 

 spaces by a series of fulvo-ochraceous lunules, not very conspicuous but often ren- 

 dered more so by an interior edging of f usco-ferruginous ; below the lower median 

 nervule this expands into a large, quadi'ate patch, generally extending slightly above
