AMERICAN LEPIDOPTERA. 105 



marginal lunules Ifirge, not touching the marginal lines, and inclosing 

 spots of the ground color, except at apex of primaries, where they are 

 paler; the rounded spots large; the mesial band heavy, confluent on 

 secondaries; the marks in cell of primaries as in the allied species; 

 on disk of secondaries a mark like the letter C inverted ; fringes ful- 

 vous, fuscous at ends of nervules. 



Under side of primaries almost wholly cinnamon-red, there being 

 but a ferruginous patch near apex and buff in the middle of the sub- 

 costal interspaces; the markings repeated; the submarginal lunules 

 black, the upper ones edged above by buff; the four or five inclosed 

 spots next apex lightly silvered. Secondaries dark ferruginous, mot- 

 tled very slightly with buff; the band between the two outer rows of 

 spots clear buff, narrow, much encroached on by the ground color; all 

 the spots well silvered ; those of the outer row long, narrow next inner 

 angle, lunular and broad on the upper half of the wing, all edged 

 anteriorly by ferruginous; of the second row, the 1st and Stli are 

 largest and equal, long semi-oval, the Gth same shape, one-half the 

 size of the 5th, the 2d and 3d equal, long and narrow, the 4th minute, 

 the 7th sublunate, all edged anteriorly by black ; the third row of three 

 spots, sublunate, edged with black; in the cell two round spots, and 

 below cell an oval, all ringed with black ; a silver spot in sub-costal 

 interspace; the shoulder and inner margin lightly silvered. 



Body dark fulvous, beneath gray fulvous on thorax, the abdomen 

 buff; legs buff; palpi buff at sides, fulvous in front and at tip ; antennae 

 fuscous above, fulvous below; club black, tip ferruginous. 



Female. — Same size. Upper side deep fulvous, less obscured at 

 base; the marginal lines on primaries confluent, and the lunules large 

 resting on the lines; the inclosed spots whitish next apex. 



Under side of primaries as in the male, except that the upper outer 

 part of cell is buff as well as the sub-costal interspaces; on the ferru- 

 ginous patch a silver spot; the upper sub-marginal spots well silvered; 

 secondaries more decidedly mottled with buff, the band still narrower.

Argynnis Opis, n. sp. 



Male. — Expands 1.5 inch. Primaries moderately arched, hind 

 margin rounded ; under side without silver. 



Upper side uniform yellow-fulvous ; primaries very little obscured at 

 base, secondaries rather largely both at base and down the abdominal 

 margin to the mesial band, that part of the wing being covered with
