P. barnesi Sm. (30 f) is extremely similar to auranticolor , somewhat smaller, of a more yellowish- bamesi. 
brown colour on the greyish-white ground, the central area prominently darker, the marginal area darker brown 
except the apex. South Dakota, Wyoming, Yellowstone Park, Colorado. 
P. genialis Grt. (30 e) is likewise similar to the preceding, but much lighter and more monotonously gcnialis. 
ochre-reddish with very faint markings and without the black streak connecting the transverse lines on the 
fold; the posterior transverse line is distally bordered with some whitish colour; the yellowish-white undulate 
line has a distinct W as far as the margin, above and below it wit grey vein-streaks. Hindwing light reddish- 
brown, in the $ darker. California. 
P. vultuosa Grt. (30 f) is much smaller than genialis, light ochre-brownish, at the costal margin and vuliuosa. 
behind the undulate line irrorated with blackish-brown, in the marginal area with black veins; the black irroration 
extends on the two folds to the postmedian line. Hindwing ochreous-grey, towards the margin darkened. Canada 
to New York. 
P. dionea Sm. (30 f). Forewing grey with a violet tint and in some places irrorated with blackish- dionea. 
brown, with a black basal ray, doidde black transverse lines, with vein-dots behind the distal line, and a connec¬ 
ting streak from the pointed coniform macula; the maculae are in whitish lings and encircled with black; be¬ 
hind the light undulate line the marginal area is blackened and black-striped, before it single black sagittae. 
Hindwing brown. Wisconsin, Dakota. 
P. apamiformis Gn. (----- contenta Wkr.) (30 g) is somewhat similar, larger, purple reddish strewn with apamifor- 
greyish-brown and dark, the anterior transverse line indistinctly double, the black connecting streak on the 
submedian fold is absent; outside below at the reniform macula there are 2 white dots. Hindwing blackish- 
brown. A common species from Canada to Colorado. — The larva is light brown, shaded with a darker colour, 
with light longitudinal lines, the dark brown neck-shield is parted by a light colour. 
P. multicolor Dyar (30 g) is very similar to apamiformis, but it is very much irrorated with blackish, multicolor. 
particularly in the central area, the double transverse lines are filled up with grey, the coniform macula is 
hardly noticeable, at the reniform macula outside a strong white crescentiform streak. Hindwing brown, at 
the margin darker with a dark central luna. Canada to California. 
P. plutonia Grt. (30 g) is the darkest species, brownish-black with lead-coloured grey irroration; at plutonia. 
the base of the costal margin and on the discal fold tinted reddish-brown; maculae in faint whitish rings; instead 
of the undulate line there are reddish-brown and black sagittae. Hindwing dark brown. Canada; United States 
as far as New Mexico. 
P. occidens Grt. (30 g) is a very large, more variegated species; forewing greyish-white, irrorated ocddens. 
with blackish-brown, in the disc reddish-brown, behind the postmedian line lighter with darkened veins and 
with double transverse lines filled up with whitish; the maculae are grey-centred and in whitish rings; behind 
the whitish undulate line the marginal area is very much darkened. Hindwing brown, veins and marginal line 
darker. Colorado (Durango), Nevada, California. -— In f. coloradensis Strd. (= ab. 1 Hmps.) the central area coloradcn- 
and the dorsal ridge on the thorax is not irrorated with brownish-red. Colorado, California. 
P. albina Grt. (30 g) is very closely allied to the preceding, with more ochre-brownish forewings, tinted albino. 
with red-brown and blackish, postmedianly irrorated with whitish, towards the hind-margin bluish; the double 
transverse lines are filled up with grey and submedianly connected by black; behind the whitish undulate line 
with a distinct W the marginal area is darkened, in front of ic there are some black sagittae. Hindwing reddish- 
brown with a central spot, postmedian line, and a broad subterminal band. California. 
P. castanea Grt. (= cymosa Grt.) (30 h) is darker than the preceding, postmedianly not lighter, caslanea. 
otherwise marked almost the same; the reniform macula is outside ochreous, below with 2 white dots; behind 
the ochreous undulate line being proximally edged with red-brown the marginal area is darkened by purple 
blackish. Hindwing ochre-brownish marked as in albina (30 f). Canada to California. -— In f. cymosana Strd. cymosana. 
(= ab. 1. Hmps.) the postmedian area is lighter yellowish. 
P. arctica Bsd. (= amputatrix Fisch., arnica Harr., pluviosa Wkr.) (30 h) is a well-known large and arctica. 
beautiful, variegated species, purple brown, strewn with greyish-white, in the basal hindmarginal area yellowish- 
white like in the distal half of the postmedian area, the double transverse lines are filled up with whitish-grey, 
the reniform macula below with 3 white dots. Hindwing greyish-brown, at the margin darker. Labrador to 
Colorado and California. — ab. formosa Ellsworth is based upon a dark $ in which the whitish colour is replaced formosa. 
by slate-coloured grey. 
P. alia Gn. (= suffusca Morr.) (30 h) is a variable species, purple grey, in the costal area tinted alia. 
red-brown sometimes as far as down to the submedian fold, the transverse lines indistinctly double, the maculae 
in grey rings, the reniform macula centred brown; before the undulate line there are proximally on the folds 
blackish spots, behind it the marginal area is darkened by brownish. -— f. rorulenta Sm. (30 h) has a more 
blackish darkened marginal area, and the reniform macula is also centred blackish. Canada to Colorado. rorulmla.
