1830 BUTTERFLIES BEYOND NEW ENGLAND. 



gin largely pale fuscous and the remainder of the wing nearly pure white, excepting 

 along the hind margin, where there is a fuscous band enclosing rounded, white spots 

 each of which itself encloses a fuscous spot on the marginal side ; the inner spot on 

 lower median interspace Is blackish, under side as on the male." 



This butterfly originally described as above by Edwards from specimens 

 obtained at San Antonio, Texas, by Boll, is stated by him to have occurred 

 also at Racine, Wise. (Hoy). Nothing more is known of it ; it presuma- 

 bly belongs to Rusticus.

Imago. Head in front snow-white with a broad, median, black-brown stripe run- 

 ning down between the antennae almost to the base; above tufted with jet black, oli- 

 vaceous and fulvous scales, the first in greatest abundance; a snow-white fringe 

 behind the eye. Palpi white, excepting the apex of the middle joint and all of 

 the apical joint but an inferior line and the extreme tip, which are blackish 

 brown ; the inferior fringe of mingled black and white hairs. Antennae black-brown, 

 with moderately narrow, basal, white anuulations on all the joints; the club itself 

 velvety black above, sordid white beneath at the base, luteo-fulvous on the naked por- 

 tions. Thorax covered with glossy black hairs, with intermingled tawny hairs, espec- 

 ially around the base of the wings; beneath covered with pure white scales and 

 sordid bluish white hairs; the legs white, the terminal tarsal joints annulate with 

 brown ; the spines dark castaneous. 



Upper surface of the wings having the disk either bronze brown with a violaceous 

 reflection, most distinct at the extreme base (<?), or dark grisly brown with scarcely 

 perceptible violaceous reflections (?). The fore wings are marked by a blackish 

 brown sjjot just beyond the middle of the cell, a black bar marking its termination, a 

 small blackish brown spot in the medio-submedian interspace, just below the flrst 

 divarication of the median nervure, and a transverse, sinuous series of spots crossing 

 the middle of the outer half of the wing, obscure brown, circular and small in the 

 male, quadrate and nearly filling the interspaces, as well as followed by narrower or 

 broader, dull orange rays in the female, in all the interspaces between the lowest supe- 

 rior subcostal and the medio-submedian inclusive; the series is more irregular and 

 sinuous in the female than in the male, and in the latter is nearly parallel to the outer 

 margin; the outer border broadly margined with dark brown, as far as midway 

 between this extra-mesial series of spots and the margin itself ; in the male the spots 

 in and at the extremity of the cell are a little more distinct than the others. Hind 

 loings with a narrow, blackish bar closing the cell, aud a little within the outer half of 

 the wing a series of spots, whose relative importance in the two sexes is as on the 

 fore wings, is found in the same interspaces as there; outer margin dark brown, not 

 so dark as on the fore wings, and with no such distinct limitation, merging insensibly 

 into the warmer tint of the disk; slight orange luuules are found, often subob.solete, 

 in the medio-submedian and lower median interspaces, in the former more distinct and 

 at the anal angle. 



Beneath, nearly uniform, very pale orange bufl"; the hind wings, however, often 

 grayer, sometimes pinkish in tone ; the markings of the upper surface are fully re-
