P. olivochroa Hmps. has olive-green forewings with a yellowish spot at the costal base, black transverse 
lines being bordered with yellowish on the averted sides, the maculae surrounded with black and whitish, the 
reniform macula proximally produced on the median, in the centre strangulated; the undulate line consists of 
black, white-striped sagittae. Hindwing light yellowish-brown. Expanse of wings: 36 mm. Peru (Agualani). 
P. quadrilineata Grt. (17 d) resembles laudabilis (16 k). Hindwing bluish-white, strewn with light brown, 
in the discal area, in the $ also in the basal area dusted with black, with a black basal area, more or less 
double transverse lines filled up with white; the small white maculae are pupilled brown and in black rings, 
before and between them often red-brown tints; the veins in the darker strewn marginal area are black, the 
thickest on the lower median branch; undulate line proximally shaded with red-brown. Hindwing diaphanous 
white, at the apex and margin brownish. California. — cimereoviridis Strd. (= ab. 1 Hmps.) has a greyish- 
green ground-colour. —- The dirty-brown larva, with a very coarse skin, has the same though more faded mar¬ 
kings as laudabilis. 
P. rugosa Morr. (17 d). The whitish forewing is suffused and strewn with brown, below the base of 
the cell with coarse black scales, with lighter, indistinct transverse lines, before the posterior line below the cell 
black dusting; the white, brownish-pupilled maculae are situate in the blackened cell, the ring-macula is obli¬ 
quely elliptical, above and below open, the reniform macula produced on the median and united with the ring- 
macula; before the light undulate line small black sagittae, behind it brown dusting. Hindwing reddish-brown, 
at the margin darker. United States (Maine). 
P. lunolacta 8m. has blackish-brown forewings strewn with black, white and greenish, with double 
transverse lines filled up with greenish, with small narrow maculae, the ring-macula in a light ring and encircled 
with black, the reniform macula conspicuously surrounded with white; the whitish undulate line is proximally 
scaled blackish, distally above the anal angle with a large white crescent. Hindwing brownish-grey, towards 
the base lighter with white fringes. Expanse of wings: 27 mm. United States (Washington, Idaho). 
P. erecta Wkr. (= constipata Wkr., innexa Grt.) (17 d) is an extremely variable species; in the type 
the ground-colour is reddish-brown, densely strewn with purple grey, with dark, but feebly bent transverse 
lines bordered with light grey on the averted sides, the maculae being surrounded with light grey, the light 
undulate line bordered by a darker colour. Hindwing diaphanous iridescent white, at the margin and on the 
veins blackish-brown. From Florida and Texas to Mexico and Guatemala. — Quite light sand-coloured speci¬ 
mens exhibiting the lower half of the reniform macula filled up with blackkh, and with a somewhat greyer 
marginal area may be called: pallens ab. nov. (17 e), in contrast with blackish-brown specimens showing hardly 
visible markings: ab. obscurior ab. nov. (17 e). —- Occasionally the subterminal space in dark specimens is con¬ 
spicuously light whitish: = ab. albifascia ab. nov. (17 e). 
P. basiplaga 8m. (17 e) is very variable, dull blackish-brown, strewn with blackish, in the upper half 
of the basal area and generally in the subterminal area reddish-brown, in the <§ dusted, towards the proximal 
margin turning into lilac, with a black basal ray and double transverse lines; coniform macula short and broad 
triangular, mostly continued to the posterior transverse line, the upper maculae rather small, in light rings, 
the reniform macula distally white; the whitish, irregularly broken undulate line is proximally defined by darker 
patches, distally by the darker marginal area. Hindwing in the 8 whitish, distally brownish, in the $ quite 
brownish-grey. Arizona. 
P. uli ginosa Sm. (17 e). Forewing dull blackish-brown, dusted white, particularly in the basal and sub- 
terminal areas, with double transverse lines filled up with whitish, and large, whitish, darker pupilled maculae. 
Undulate line entirely blurred, whitish. Hindwing in the $ white, in the $ smoky. South Arizona, Texas. 
P. vittula Grt. (17 e) is very similar to uliginosa, of a lighter grey, dusted and strewn with blackish- 
brownish, with a black basal ray and double transverse lines with somewhat lighter fillings, between them 
the median area is somewhat darkened; the small maculae in grey rings and encircled with black, between 
them an indistinct bent median line; the postmedian area is somewhat lighter, the undulate line but indistinctly 
defined against the darker marginal area, towards the anal angle more distinctly marked black and with a 
black anal ray. Hindwing white with brownish veins and margin. New Mexico. 
P. intentata Sm. (17 f) is much larger, forewing brownish-grey, strewn with black, in the discal area 
tinted yellowish, particularly below the cell; transverse lines double, yellowish-white, the posterior line filled 
up with reddish; the maculae in whitish rings shoAV darker pupils, the whitish undulate line is on both sides 
bordered with blackish-brown. Hindwing white, on the veins and margin brownish, in the $ quite brownish- 
grey. From Colorado. 
P. roseosuffusa Sm. (17 f) has a whitish forewing suffused with pink, dusted with brownish-grey in the 
basal half as far as the discal shade, postmedianly at the costal margin, proximal margin and in the centre, as well 
as in the marginal area; the anterior transverse lines are double, filled up with whitish, the posterior line is single, 
dentate; the maculae are very small and indistinct, the ring-macula encircled with whitish, the reniform macula 
is a darker patch; before the whitish undulate line there are darker spots. Hindwing yellowish-brown. Arizona. 
P. falsa Grt. is a species doubtful in its classification, similarly marked as intentata (17 f), smaller, with 
more bluish-grey forewings and a somewhat reddish-brown tint in the discal area, the hindwings being all white 
From California.
