P. famhami Grt. (15 h). Purple-grey, in the disc browner, with darker veins, double transverse stripes farnhami. 
filled up with a lighter brown, and a dentate median line; the coniform macula is large, encircled with black, 
the upper maculae are small, with reddish pupils, the reniform macula with a whitish line proximally, 
before the ring-macula a small white spot; undulate line whitish with a distinct W and black sagittae proxi¬ 
mally, the apex is parted by a whitish patch; marginal area brown. Hindwing brownish with darkened veins 
and margin. Canada, Colorado. 
P. prodeniformis Sm. (15 g) is similarly marked as farnhami, but easily discernible above all by the prodenifor- 
light splinter-like spot extending above the long coniform macula to the postmedian line; the veins, the costal 
area and the proximal half of the postmedian area obliquely extending to the apex dusted with a greyish white; 
the undulate line is yellowish-white with a long, pointed W. Hindwing whitish with a broad brownish-grey 
marginal band. From New Mexico in the United States to Mexico. 
P. liquids Grt. (15 h) resembles ‘prodeniformis, but it is much larger, more bluish-grey, only in the discal liquida. 
area brownish, the double transverse lines filled up with a light bluish grey, the light splinter-spot is mostly 
only a narrow grey streak on the lower median branch. Hindwing more extensively dark with a whitish post¬ 
median band. Washington, Oregon, Colorado. 
P. meodana 8m. (15 h) is very similar to liquida, but the wings are broader, less pointed, the marking meodanct. 
is the same, but it is of a much more uniform appearance and not so contrasting on a light bluish-grey ground 
dusted with reddish-brown; the narrow double transverse lines are filled up with white; the proximal-marginal 
vein and the lower median branch are decidedly dusted with white, the others only traceably so. Hindwing 
yellowish brownish-grey with a darker distal margin. Expanse of wings: 32 to 38 mm. Canada, Washington, 
Wyoming, Colorado. 
P. tacoma Streck. (15 h) is much more variegated than the preceding, in the basal and subterminal iaeoma. 
areas violettish-grey, in the discal area reddish-brown, the reniform macula pupilled ferruginous-brown, the 
cell before and between the maculae filled up with black, similar to the angles of the median branches; the 
filling of the transverse veins, the ring-macula and a costal spot above it are grey; undulate line white, on both 
sides shaded with reddish-brown. Hindwing brownish-yellow, darkened at the margin, only near the anal 
angle narrowly whitish. Canada; Washington. —- The larva is light green with lighter, yellowish longitudinal 
lines being bordered with dark; it lives on Rubus and low plants. 
P. atlantica Grt. {= discolor Speyer) (15 i). Greyish-brown, except the costal-marginal area suffused aUanlica. 
with red-brown, with a black basal ray and plain transverse stripes bordered with grey, as well as a yellowish- 
white, sharply dentate undulate line with a W extending to the margin; the coniform macula is dark brown, 
encircled with black, the upper maculae in grey rings, below the reniform macula black shading; the narrow 
marginal area behind the undulate line is very dark. Hindwing brownish, towards the margin darker. Canada; 
Eastern States to Virginia. This species is better ranged more in front between subjunctae and nevadae. 
P. quadrata 8m. (15 g). Dark red-brown, strewn with a lighter colour, in the subterminal area lighter, quadratci. 
more reddish; transverse lines single, bordered with whitish, behind the distal line black, white-dotted streaks 
on the veins; the maculae are scarcely lighter than the ground, encircled with dark; before the light undulate 
line with a distinct W black sagittae. Hindwing reddish greyish-brown with light fringes. California. —• The 
larva is marbled darker on a yellowish-brown ground, with darker dentate dorsal ornaments and somewhat 
lighter longitudinal lines. Presumably polyphagous. 
P. radix Wkr. (= dimmocki Grt., desperata Sm.) (15 i) has deep red-brown forewings dusted with radix. 
grey, with a black basal ray, double transverse lines filled up with grey, and large maculae encircled with black; 
there is also a black median line; the whitish undulate line provided with a distinct W shows proximally small 
red-brown sagittae. Hindwing brownish-grey with whitish fringes. Canada to California. — The greyish-brown 
larva has oblique dark subdorsal spots and light yellowish dorsal and subdorsal lines. It lives polyphagous 
on many low plants. 
P. congener Hmps. has grey forewings in some places dusted with brown and strewn with black, 
with double black transverse lines filled up with white, the coniform macula encircled with black, the upper 
maculae in white rings and encircled with black and between them with an indistinct black median line; the 
undulate line consists of a bent row of small white spots on black diffuse patches which are distally bent at 
the anal angle. Hindwing white with a brownish basal area, veins and proximal margin, whilst the distal margin 
is brown. A most variable species. — In the form aurantitincta nom. nov. (=- ab. 1 Hmps.) the proximal half 
of the basal area and the space before the undulate line is strewn with orange, in albimacula nom. nov. (= ab. 
2 Hmps.) the two upper maculae are all white, like the postmedian area. Expanse of wings: 34 to 38 mm. — 
South-Eastern Peru. 
P. albitela Drc. Forewing dark red-brown, towards the base yellowish ; at the cell-end a large V-shaped, albitela. 
yellowish-brown spot, subterminally a broken band of similarly coloured spots; on the margin there is a row 
of small, indistinct grey spots, behind the coniform macula a hook-shaped, large, white spot not reaching to 
the proximal margin. Hindwing dirty white, with abroad smoky margin. Expanse of wings: 38 mm. Peru. 
P. erythurus Drc. Forewing dark brown, the upper maculae very indistinct; the posterior transverse eryfhv.ru 
line consists of small black dots on the veins; behind the coniform macula a hook-shaped yellow spot; the 
congener.
