terminal markings. 2 very much like 3, but the markings heavier, standing out very distinctly against the 
dark ground; the marginal spots enclosed by the lunules very light in colour and relatively large. On the 
underside the forewings are suffused with red, very much as in adiante 9. Expanse: g 1,75—2,0’, 9 2,0—2,15”. 
Its home is Utah, Arizona, Colorado and Montana. 
A. clio dw. (87 d) is, after bischoffi, one of the most northern representatives of the ewrynome group. 
Both sexes have the upper surface more brillant and deeper fulvous than in ewrynome, in the Q paler than 
in g, with the markings not very heavy and the base moderately obscured. Terminal border fairly broad, 
especially in 2, the marginal spots enclosed between it and the submarginal lunules, standing out distinctly 
from the darker ground-colour. As in artonis, the spots on the under surface are entirely devoid of silver. 
Altogether these two species have so much in common that it is difficult to always distinguish them with any 
certainty. Expanse: $ 1,8’, 21,8—1,9’’. This species or variety is confined to the higher mountains of Montana 
and Alberta (ELWES, GEDDES). 
A. opis Hdw. (87e) is the form of British Colombia; its size is considerably less than even that of 
clio; from eurynome it differs, aside from its inferior size, in the very pronounced obscuration of the base and 
abdominal margin on the upper surface in both sexes, and in the heavier markings on a duller ground. With the 
exception of the species of the Brenthis group, it is the smallest of all American Argynnis. Forewings 
short and slightly arched; the lower part of the basal area and the inner margin densely covered with brown 
hair. Inthe 3 the under surface of the forewings is very slightly, if at all, tinted with red at the base, and the 
submarginal spots are nearly obsolete. Hindwings with discal area pale ochreous, faintly mottled with reddish; 
submarginal band indistinctly marked by a faint pale streak. All the spots pale, dull ochraceous, not silvered. 
2 deeper fulvous, with both wings heavily obscured from base to median band, and all the markings heavier 
than in g. Underside of forewings tinted with red throughout, except at apex which is ochraceous. Hind- 
wings asin gj. Expanse: 3 1,5’, 91,6’. The type was captured by G. R. Crorcu in 1873 on Bald Mountain, in 
the Caribou District of British Columbia. 
A. bischoffi Ldw. (87 d) represents the ewrynome group in the far North. g above bright fulvous, the 
base of the forewings and the inner half of the hindwings deeply shaded with purplish-black, so as to con- 
ceal the markings. Both wings bordered with moderately heavy terminal lines enclosing a series of small fulvous 
spots which may be obsolete on the posterior half of the forewing. Otherwise the upper side as in eurynome. 
Underside of forewings buff, with the basal and discal areas reddish. Hindwings pale buff, the inner two thirds 
shaded with greyish-green. Submarginal band clear buff; the spots on the under surface in the majority of cases 
simply buff, without any silver, occasionally almost obsolete; in other cases they are fairly well silvered. 
2 above very pale buff, slightly laved with reddish distally. All the markings deep black and heavy. On the 
forewings the base, on the hindwings more than the inner half deeply obscured with black; both marginal lines 
united into a broad, solid black band; between this and the submarginal lunules a series of almost white spots. 
Besides these and a narrow pale streak in the outer discal area of the forewings and at the apical end of the 
costal margin, and besides the dirty white spots corresponding to the second row beneath, there remains no- 
thing of the pale fulvous ground-colour. Underside very much as in 3; also here the spots may or may not 
be silvered, but the silvering generally predominates. Expanse: 3 1,8’, 2 1,9”. It home is Alaska; the types 
were captured near Sitka in the middle of July. 
A. eurynome Hdw. (86e). Forewings slightly arched, feebly produced apically. 3 above bright yellow- 
ish-fulvous, but little obscured at the base. The black markings moderately heavy, the terminal lines fre- 
quently confluent so as to form a solid band. Submarginal lunules united, enclosing a series of fulvous 
spaces of the ground-colour. The rounded postdiscal spots small, the median spots connected by fine lines so 
as to form a delicate zigzag-band. Underside of forewings pale buff, shaded with cinnamon-brown at base 
and along the nervules; marginal and subapical spots well silvered. Hindwings yellowish, with the basal and 
discal areas mottled with light ferruginous or more often with pale olive-green. Submarginal band clear buff; 
all the spots, the basal portion of the costa, and the inner margin well silvered. Q marked very much like the 
3, but paler, with the dark markings, especially those at the margin, heavier. The marginal spots enclosed 
by the black lunules much paler than the ground-colour, occasionally almost white. The second row of silvered 
spots beneath is indicated above by a faint pale discal streak. Under surface as in g, but the forewings more 
heavily obscured with deep cinnamon-brown at the base. Expanse: 3 1,7—2,0”, 2 2,0’. — The egg resembles 
that of other known species, with 20 strong verticals ribs, intersected by shorter horizontal ribs, and marked 
with numerous horizontal striae. Colour at first honey-yellow, later on turning into purple. Neither the larva 
nor pupa are known. eurynome abounds in the mountains of Colorado, Montana, British Columbia and Alberta, 
where according to Mmap it flies on grassy fields along the streams. In Colorado it appears in the first half of 
June; in Utah, Arizona and New-Mexico it has not been observed so far. — A. arge Strecker, from California 
and Washington, is probably a variety of ewrynome, connecting this with montivaga, but slightly different from 
or perhaps identical with erinna Edw. (86 e) which replaces the latter in the North, in Alberta and British Co-
