brown; primaries have a broad, black hind margin, enclosing a series 
of fulvous lunules, sharply serrate upon its inner edge; otherwise 
marked as in the allied species. 
Secondaries have the margin bordered by two parallel lines which 
enclose a fulvous space; the median line zigzag and continuous, as in 
Atlanth. 
Under side of primaries fulvous; the apex, upper marginal serra¬ 
tions and the sub-apical patch deep ferruginous of the same hue as 
secondaries; the marginal lunules and apical interspaces buff. 
Secondaries deep ferruginous, except the space between the outer 
rows of spots, which is buff, and not encroached upon by the basal 
color, except at the extremities, where there are a few ferruginous 
scales; the marginal lunules buff, serrated, with serrated ferruginous 
borders; the second row consists of eight spots, the eighth being in¬ 
complete on the abdominal margin; the first six long oval, the seventh 
lunular, all edged above with black, and below projecting a shadow of 
deeper ferruginous; beyond these is a row of four spots, the first being 
on the costa and lunular, the second semi-oval, in the cell; the third 
and fourth almost wanting, but all four heavily edged with black above; 
in the cell two round spots circled with black, one of them minute; an 
oval buff spot at the base of median nervure ; a slight patch at base of 
costal nervure; the edges of costa at base and of abdominal margin 
lightly marked with buff; all the spots, except the marginal, somewhat 
sprinkled with silvery scales, but which are scarcely perceptible with¬ 
out a glass. 
From the Rocky Mountains. 
In a paper read by Dr. Behr, 21st April, 1862, before the Academy 
of Natural Science of San Francisco, on the Argynnides of California, 
he enumerates nine large and well marked species, none of which are 
known on the Atlantic slope. This does not include A. Nokomis Edw., 
from the Rocky Mountains, the largest and finest of all the Western 
species, or Hesperis, above described. 
Dr. Behr adds.—“ The only representative of the Arctic form of 
Argynnis as now known in California is A. Epithore, Boisduval.’^ 
This species, as I am informed by Dr. Behr, is undescribed and only 
named in letters of Dr. Boisduval. From a male sent me from Cali¬ 
fornia I have described it as follows.
