and extends, diminishiiis in widtli, to the middle of the inner margin ((J), or to the 

 base, occupying the whole of the inner margin, as far as the siil)median nervure ( ? ) ; 

 the extreme outer edge of the wing is darker tlian tlie border, and tlie fringe is dull 

 tawny, paler in the lower fourtli, sometimes largely infn.scated in the upper half or 

 three-fourths. Hind triiu/s having the costal margin bordered, as far as the subcostal 

 nervure, with l)lackish brown, in tlie $ also occupying llie upper half and the termina- 

 tion of the cell ; outer margin bordered either rather narrowly, to less than half the 

 width of an interspace ((J), or rather broadly to about the width of an interspace ( ? ), 

 with blackish brown ; a similar bordering follows the inner margin as far as the sub- 

 median nervure, but is rendered inconspicuous next the nervure by a plentiful supply 

 of long, tawny hairs; similar hairs are found next the base, where the wing would 

 otherwise be somewhat infuscated; the apical portions of thenervules, and generally 

 also the whole of them, are delicately traced in black. Fringe tawny, paler next tlie 

 anal angle, sometimes faintly cut witli dusky at tlie tips of the nervules. 



Beneath, /ore uu'/ii/s dull, slightly paler tawny, with a slight greenish tinge. Inner 

 border broadly l)ordered with blackish fuliginous, as far as the middle of the cell in 

 the basal half of the wing, to the submedian nervure only on the outer half; similarly 

 the lower half of the outer border is sometimes more or less broadly margined; the 

 oblique dash at the tip of the cell repeated as a delicate line. Fringe slightly paler 

 than above, but otherwise similar. Hind icings rather dark greenish yellow, between 

 the median and internal nervures tinged with orange. Fringe much as above. 



Abdomen blackish, the sides heavily clothed with fulvous hairs, which obscure also 

 most of the upper surface, beneath changing to yellowish. Upper organ of male 

 appendages (37:11) smaller than in tlie other species, and differing from them in 

 being stoutest in the middle instead of distally, tapering from almost the very base; 

 it also arches less than they, and the hook is more clearly divided, though tlie two 

 halves together continue the regular tapering of the centrum, and are pointed at tip 

 and slightly hooked. Lateral arms consisting of an inferior plate, separate from the 

 hook, depressed, curving slightly upward and tapering to a point, scarcely shorter than 

 the hook. Clasps a little more than half as long again as broad, the lower process 

 pretty broad and equal, a little incurved, directed about equally upward and backward, 

 pointed at the tip a little above the upper level of the clasp ; upper process scarcely 

 more than a bluntly rounded angle of the clasp. 



Described from 9 (5 , 7 ? . 



Caterpillar. Last stage. Head oval, oblique, white, smooth, slightly bilobed; a 

 black band about top and sides, a black, vertical streak on the middle of the face, and a 

 short streak of same color on either side this last. Thoracic shield black, ending in a 

 black dot on either side ; body fusiform, color bluish white; a lunate black band on 

 penultimate segment and anal plate; the surface thickly dotted with minute black 

 tubercles. Length, 25 mm. (After Chapman.) 



Chrysedis. "Narrow, greenish -white, the head-case blunt, black, tubercled and 

 bristly, the last segment black." (Chapman.) 



Distribution (30:2). This butterfly is found over the whole extent of 

 the Carolinian fauna from Florida (Chapman) to Texas (Capt. Pope) and 

 over the southern half of the AUeghanian fauna. The northernmost lo- 

 calities from which it has been reported are Albany, N.Y., (Lintner), 

 Lansing, Mich. (Edwards), the township of Ohio, 111. (Morrison),
