ARGYNNIS. 43 



round ; the exterior crescent. In the discoidal cellule there are 

 some marks as in the analogous species. Tiie outer edge is pre- 

 ceded by a black line crossed by nervures of the same color. 



Under side of the primaries like the upper, except that the base 

 is fulvous ; and opposite the summit there are some silvery spots, 

 of which four or five rest on the black crescents. 



Under side of the secondaries brown ferruginous, with the base 

 and about twenty-four spots, nacre ; the spots at the base are 

 small ; those of the middle larger ; those of the edge triangular, 

 and separated from the preceding by a yellowish band, losing itself 

 in the ferruginous. 



Body brownish ; antennse blackish ; club black, tipped with 

 fulvous. 



This species is usually confounded with A. aphrodite, but is 

 different, as will be seen from the description. 



United States. — Expands nearly three inches.

4. A. aphrodite Fah. Fab. Syst. Ent. Ill, 1, 144. Similar to A. cyhele, 

 for which, it is usually taken. 



Primaries tawny orange brown at base, spotted, inscribed and 

 reticulated with black ; at the posterior margin, a deep orange 

 band, edged with black; above this, a series of black crescents, 

 succeeded by one of round spots ; the costal margin is barred with 

 black, the three anterior bars being angular, and the fourth shaped 

 like the letter P ; this is followed by three others less distinct ; 

 the reticulations of the disk terminate posteriorly in a zigzag black 

 band ; underneath, at the external angle, are five silver marginal 

 series of crescents, above which the wing is spotted with black, 

 with a few paler spots surmounted by a black crescent; underneath 

 they are reddish brown, with a pale, tawny, marginal band, A 

 marginal series, consisting of seven silver triangular spots, edged 

 with black, next follows; and a second series, consisting of the 

 same number, differing in shape, edged also with black, the inter- 

 mediate one being the smallest; a third series of four spots suc- 

 ceeds, that next the costal margin is crescent-shaped ; the second 

 is subtriangular, divided by a black line ; the third is oblong ; the 

 fourth minute. At the base arc five spots, varying in form ; on 

 the shoulders is also a silver spot, and the inner margin is silvered, 

 but less conspiculously. Fringe pale, barred with black.
