AMERICAN LEPIDOPTERA. 107 



fringes luteous, fuscous at the tips of the nervules. Under side of 

 primaries buff, tiuted over basal area and disk with fulvous, at apex 

 ochraceous; the markings of the disk repeated; the upper extra-discal 

 spot6 wanting ; the sub-apical patch indistinct, ferruginous ; the sub- 

 marginal spots are of the ground color with no silver. 



Secondaries nearly same shade as primaries, the nervules ferruginous, 

 and a tint of that color on the disk, especially at the top of the sub- 

 uiedi.in interspaces; the basal area and inner margin as ftir as cell 

 mottled with olivaceous, dusted with black scales; all the spots buff, 

 with no silver and all those of the three rows edged above by a dust- 

 ing of black scales ; on the 2d row the first three, 5th and 6th are 

 nearly equal, subovate, the 4th minute, the 7th lunular, and nearly all 

 of this row have a small spot, composed of loose black scales, at the 

 posterior side; the third row of three spots, semicircular; a 4th spot 

 nearly obsolete next inner margin ; in the cell an irregular spot; a long 

 oval below cell, and a buff patch at base of sub-costal interspace. 



Body above dark fulvous, below thorax gray-buff; abdomen buff; 

 legs buff; palpi buff at sides, fulvous in front; antennae fuscous above, 

 fulvous below ; club black, tip ferruginous. 



Female. — Same size. Paler, the base more obscured ; the marginal 

 lines heavy and confluent; the lunules heavy, inclosing spots which 

 are buff on secondaries, nearly white towards apex of primaries; a 

 whitish shade over the sub-costal interspaces of primaries; all the 

 markings heavy. On the under side of primaries the fulvous tint is 

 deeper, otherwise as in the male. Secondaries have the ground in- 

 clining to ochraceous, mottled as in primaries; the spots entirely 

 destitute of silver. 



This species resembles Enrynome in size and shape. The first 

 examples % % seen by me were brought in by Dr. Hayden's last 

 Expedition to Montana, and were taken on the plains at the Teton 

 Mountains. In 1874, a 9 was sent me by Dr. Coues with other 

 butterflies taken by the Northern Boundary Line Expedition, in the 

 Rocky Mountains. 



Grapta Rust icii»>, n. sp. 



Male. — Expands 1.9 inch. Both wings moderately incised; tail 

 long, broai, followed by a deep sinus and a dentation equally promi- 

 nent with that at inner angle. 



Upper side dull sordid fulvous, pale next apex of primaries; the 

 marginal borders broad, that of secondaries occupying one third of 

 the wing, well defined on its inner edge ; the submarginal lunules
