white. Both sexes in numbers received from Mexico (Zacualpan), taken in May. 
P. selama Streck. has blackish-brown, silky lustrous forewings strewn with grey, with black transverse 
stripes bordered with grey; coniform macula absent; marginal area grey with an indistinct black marginal 
line. Hindwing brownish-grey, towards the base lighter with whitish fringes parted by dark. Expanse of wings: 
28 mm. Texas. 
P. insolens Grt. (= carina Morr.) (15 d). Forewing whitish or yellowish-white, densely dusted and 
strewn with a dark brown, with single blackish transverse lines, the posterior line dentate; coniform macula 
marked with brown, the upper maculae large, surrounded with whitish or yellowish : the uniformly bent undulate 
line is proximally bordered by small blackish-brown sagittae, behind it the marginal area is darkened. Hind¬ 
wing whitish, dusted with brown. From California (San Francisco). 
P. plicata Sm. (15 a) has grey fore wings densely strewn with blackish-bro war, the cell and disc dusted 
with red-brown, with somewhat darker striped veins; transverse lines double, filled up with grey, before the 
posterior lines traces of an undulate median line; coniform macula grey, surrounded with brown, the upper 
maculae grey, surrounded with black, the reniform macula below pupilled dark; the undulate line is whitish, 
the hindwing greyish-brown. Canada and Colorado. 
P. negussa Sm. (15 b) is smaller, of a lighter grey, only in the marginal area except the apex much 
darker, with a very distinct median line which is almost rectangularly broken at the lower cell-end, the reniform 
macula being larger, more strongly angled, with postmedian black, white-dotted streaks on the veins; before 
the distinct light undulate line at the costal margin a more darkened area. The hindwing is of a darker 
greyish-brown. Saskatchewan. 
P. tristis B. & McD. (15 c). Forewing deep purple grey, in the discal area shaded with brown, with 
a black, above ochreous yellowish basal ray; the black transverse lines are close together at the proximal margin 
and above it connected by a black streak above which there is browui colouring; maculae grey, surrounded 
with black, behind the reniform macula a purely brown area; undulate line white, interrupted, above the anal 
angle a spot scaled grey and yellowish, above it a black streak; fringes speckled dark. Hindwing smoky grey 
with a darker margin. Arizona. 
P. purpurea B. <£• McD. (15 c) is somewhat similar to tristis, larger; the discal and subterminal 
areas are less brown than lighter reddish; the maculae are much more intensely surrounded with black, chiefly 
on the proximal sides, between them the cell is darkened with purple, behind the reniform macula there is a 
reddish tint; there is no streak connecting the transverse lines; undulate line very distinct, proximally bordered 
with a blackish brown. Hindwing smoky grey. Arizona: 
P. grandis Bsd. (= libera Wkr.) (15 b) is still somewhat larger than jpur'purea, on the purple grey 
forewing more intensely dusted with red-brown, with a black basal ray, and a black stripe from the end of the 
short, broad coniform macula to the postmedian line behind which the subterminal area is dusted with a lighter 
lilac grey; the white undulate line with a distinct W is proximally bordered with red-brown and with small 
black sagittae, the marginal area behind it dusted almost with black. Hindwing yellowish brownish-grey. 
A common species from Greenland through Canada to Colorado. — The greyish-brown larva without distinct 
markings lives polyphagous on the ground on all kinds of low plants. 
P. subjuncta Grt. <£• Rob. (15 c) is on an average somewhat smaller with narrower wings, very 
similarly marked as grandis , still more dusted with red-brown, particularly behind the reniform macula as 
far as the apex; the coniform macula is larger, the subterminal area not lilac-grey but brownish-red, the hind¬ 
wing much lighter whitish, tinted brownish, on the veins and margin more intensely brownish. Canada to 
New Mexico. — The greenish larva is watered with brown and shows oblique dark subdorsal shades and a broad 
reddish lateral band being upwards bordered with yellow; it lives on low plants. — eleanora B. McD. (15 d) 
from South California is much lighter, greyer, without reddish-brown tints, only above the basal ray and behind 
the coniform macula somewhat brownish. 
P. nevadae Grt. (15 c). Forewing dark reddish-brown, at the costal and proximal margins strewn 
with white, at the base of the costal margin as far as the black basal ray yellowish-white; the transverse lines 
are rather indistinct, on the averted sides bordered with whitish, the undulate line white with a distinct W; 
the coniform macula is small, the upper maculae are whitish, the reniform macula crossing the cell below, here 
pupilled blackish. Hindwing brownish-grey with whitish fringes. Canada to California. —- The larva is dark 
brown with a broad dark dorsal band and connected with it there are oblique subdorsal shades, as well as a 
broad, white lateral band dusted with reddish. — canadensis 8m. is much greyer, almost without any reddish 
tints, with a still less distinct marking. From Canada. 
P. ingravis Sm. (15 cl) is likewise very similarly marked as the preceding, the ground-colour is brownish- 
grey, dusted with purple grey, with a black basal ray, a large, grey coniform macula being surrounded with 
black; the upper maculae are large, in whitish rings and surrounded with black, between them a faded dark 
median line; the subterminal area as far as the white undulate line with a distinct W is purple grey, behind 
it darkened. Hindwing blackish brown, at. the margin blackish with reddish fringes. From Canada (Calgary, 
British Columbia).
