AMERICAN LEPIDOPTERA. 17 



being but partially fuscous ; the anterior portion of these spots, on both 

 margins, cut off by an irregular black line ; the 4tb row is basal and 

 is separated from the 3d by a broad space, and consists of four irregu- 

 lar, confluent spots; the outer edges of the band thus formed edged 

 with black ; the 4th spot confluent with the con-colored abdominal 

 margin; in cell an orange bar on either side the triangular spot; a 

 similar bar in the interspace above cell, and an orange lunule in sub- 

 median interspace next submedian nervure, and a small orange trian- 

 gle at origin of lower branch of median ; an orange bar also next the 

 basal side of the 4th band. Body above black with fulvous hairs ; 

 rings of abdomen edged with yellow; below, thorax and abdomen, 

 yellow-white; legs pale fulvous; palpi same above, yellow-white in 

 front; antennae fuscous, with narrow white rings, below orange cre- 

 taceous next base; club fuscous, orange below and at tip. 



Female. — Expands 1.9 inch. Color of upper side sometimes like 

 male, sometimes paler ; in some individuals the submarginal spots and 

 the third, or discal row, are paler than the rest of the wing; and the 

 three outer rows on primaries likewise paler; under side similar in 

 color and markings to male. 



From Montana, Nevada and Southern Utah. Specimens have been 

 received from Dr. Hayden's Expeditions and Lieut. Wheeler's of 1872. 

 Also from Henry Edwards, Esq. This species is at once distin- 

 guished from its allies by the yellow-white under surface, especially of 

 secondaries, this color nearly occupying the whole wing. 



Synchloe Crocale, n. sp. 



Male. — Expands 1.7 to 1.9 inch. Upper side brownish-black, 

 spotted with white ; primai-ies have a sub-marginal row of points, 

 sometimes complete from apex to lower branch of median, but usually 

 in part obsolete, the two spots on first and second median interspaces 

 only appearing; a sinuous extra-discal row of points or small spots 

 across the entire wing, seven in all. but sometimes the one next inner 

 margin accompanied by an eighth ; a discal row of conspicuous spots, 

 also sinuous, usually incomplete by the absence of one spot from 

 upper median interspace, — this spot when present, minute; and a 

 narrow spot in cell, often wanting ; secondaries have a transverse row 

 of spots on middle of wing, which are regular, narrow, elongated, and 

 equal; at anal angle a fulvous patch, which extends a little distance 

 up the abdominal margin ; fringes white, black at tips of nervules.
