ARGYNNIS VII. 
ARGYNNIS HESPERIS. 1—3. 
Argynnis Hesperis, (Hes'-pe-ris) Edwards, S , Proc. Ent. Soc. Phil, ii, p. 502. 1864. 
Primaries long, narrow, moderately arched, hind margin slightly convex. 
Male. Expands 2.3 inches. 
Upper side deep fulvous, obscure at base ; primaries have a narrow black hind 
margin ; the submarginal spots serrate and confluent. 
Secondaries bordered by two fine parallel lines on which the spots are serrate, 
sometimes dentate ; the median spots form a narrow, confluent band, as in Atlan- 
tis ; other markings of both wings as in that species ; fringe yellowish, black at tips 
of nervules. 
Under side of primaries pale fulvous inclining to luteous ; the apex, upper 
part of margin, apical patch and upper serrations ferruginous ; the spots within 
the latter buff ; lower serrations blackish enclosing fulvous spots ; the spots on patch 
buff as also are the apical interspaces. 
Secondaries deep ferruginous, excepting the space between the two outer rows 
of spots, which is buff, and immaculate ; (but occasionally this space is encroached on 
by the basal color, as in Aphrodite ;) the spots are 23 or 24 in number, viz : the mar- 
ginal row of seven, triangular, edged above with ferruginous ; the second row of 
eight, mostly narrow and elongated ; the eighth, on inner margin, lunular and in- 
complete ; all but the eighth projecting a ferruginous shadow on the buff belt and 
all edged above with black ; the third row of four or five, the first lunular, second 
minute or wanting, third semi-oval, cut into two by the arc, the lower part edged 
above with black, the fourth and fifth streaks ; all these are edged above with black ; 
within the cell one or two small round spots ; an oval at base of median ; these 
last wholly edged with black; a patch at base of costal; shoulder and abdo- 
minal margin greyish ; all the spots are buff, some of them occasionally sprinkled 
with a few scales of silver. 
Body above color of base ; beneath greyish ; palpi reddish-grey ; antennae ful- 
vous, club black tipped with ferruginous. 
Female. Expands 2.4 inches. 
Paler colored, but otherwise similar to the male. 
Found in Colorado, and first taken by Mr. James Ridings in 1864. It seems 
to be not uncommon in that region.
