P. obesula Sm. (15 c) is on its yellowish-grey ground dusted with reddish-grey and brown, with 
double blackish transverse lines filled up with a lighter colour, a narrow dark median shade, a large, broad, 
dark coniform macula surrounded with black, and dark-pupilled, light-ringed upper maculae; the undulate 
line is light with a distinct W, before it black sagittae. Hindwing light yellowish with a broad blackish marginal 
band and discal luna. Expanse of wings: 30 to 34 mm. Canada, Colorado. — ortruda Sm. exhibits a more uni¬ 
formly reddish-yellow ground-colour with somewhat more coherent, more distinct markings and a ferruginous- 
yellowish abdomen. From Colorado. 
P. passa Morr. has light ochreous forewings dusted with red-brown and strewn with blackish, 
with a black basal ray, with indistinct double transverse lines, the subterminal area strewn with whitish; the 
coniform macula is large, surrounded with black, the upper maculae large, light, surrounded with black, the 
ring-macula obliquely elliptical, above open, behind the reniform macula reddish dusting; the undulate line 
is very uniform, white, proximally marked blackish-brown. Hindwing brownish-grey. Expanse of wings: 
34 mm. California. 
P. vau-orbkularis Sm. Forewing ochreous-grey, dusted and strewn with a blackish brown, with double 
indistinct transverse lines, behind the postmedian line yellowish dots on the veins; the coniform macula is 
absent, the upper maculae are small, the ring-macula V-shaped, bordered with jet-black, with a broad faded 
median shade; the yellowish undulate line is proximally defined by black spots. Hindwing brownish-grey, 
towards the base lighter. Expanse of wings: 35 mm. Oregon. 
P. pyrosoma Hmps. (15 e). Forewing deep chestnut, dusted with a blackish brown, the veins blackish- 
brown striped with lustrous leaden grey; the single black transverse lines are on the averted sides bordered 
with leaden grey; the coniform macula is finely encircled with black and exhibits a yellow wedge-shaped spot 
behind it; the upper maculae are leaden-grey, red-striped in the centre, the reniform macula on the median 
long proximally produced; the undulate line is composed of yellow internerval streaks, behind it a black and 
anal wards a yellow oblique stripe; fringes at the base red. Hindwing reddish brownish-grey. The abdomen 
is fiery red, at the base whitish. Peru, Colombia. 
P. ardelio sp. n. (15 e) resembles pyrosoma , it is smaller, much darker, more purple black, intermixed 
with carmine and bluish-violet scales, otherwise very similarly marked; the maculae are much darker purple 
brown, only very narrowly bordered with whitish; the white hook-shaped spot behind the coniform macula 
has changed into a narrow, oblique, white line extending towards the anal angle; the veins in the marginal area 
are not so broadly light-striped; the undulate line consists of jet-black, white-pupilled sagittae. Hindwing 
much lighter, whitish, in the disc diaphanous. Described according to 1 $ from Bolivia (Cuesta de Cillutincara). 
P. invalida Sm. (15 e) is on the greyish-white forewing dusted and strewn with blackish-brown, with 
a black basal ray and double transverse lines as well as a faded median line; the coniform macula is uncommonly 
large and broad, from its apex a black streak extends to the posterior transverse line behind which there is 
a whitish spot towards the proximal margin; the upper maculae are large, in white rings and encircled with 
black; the white undulate line with a distinct W is proximally defined by long black sagittae, and there are 
also distally black internerval streaks. Hindwing dusted with brown. From Oregon, Colorado, and California. 
— The red-brown pupa with whitish longitudinal stripes and oblique blackish-brown subdorsal shades lives 
polyphagous. 
P. cristifera Wkr. (= impolita Morr.) (15 e) resembles invalida ; the purple grey forewing is dusted 
with black and strewn with white particularly at the costal margin, with double transverse lines filled up with 
grey and a grey spot behind the posterior line near the proximal margin; the maculae are pupilled dark and 
in grey rings, between them an undulate median line; the undulate line consists of small white lunae, proximally 
accompanied by black sagittae. Hindwing ochreous-brownish. Canada, United States. 
P. lubens Grt. (= rufula Morr.) resembles cristifera, but in the antemedian area it is dusted with 
red-brown, the reniform macula is in a ring of pure white, the subterminal area is of a purer grey, the undulate 
line coherent and proximally shaded with red-brown. From New York, Washington, Colorado. — f. glaucopis 
Hmps. (15 d) has the reniform macula in a yellowish ring. Canada (Vancouver). 
P. caloscotina Dyar (15 e). Forewing very broad, lilac-grey, dusted with brownish and strewn with 
black, with double transverse lines and rather large maculae, surrounded with black and pupilled darker; the 
reniform macula is tinted reddish with a fine dark central streak and is very obliquely situate and becomes 
more prominent owing to a dark median shade proceeding from the costal margin and being closely adjoining 
to its proximal margin; the proximal half of the basal area is darkened; the undulate line is close to the margin, 
very indistinct and composed of roundish, brown, small spots in lighter rings. Marginal area darkened with 
black streaks on the veins and a more intense stripe on the submedian fold. Hindwing brownish-grey. Mexico. 
P. latex Gn. (— demissa Wkr.) (15 f) has greyish-white forewings strewn with brown and black, 
with darker veins and a blackish costal-marginal spot near the base, indistinctly double black transverse lines 
and arge maculae surrounded with black, the reniform macula with a bright ferruginous red pupil; behind 
it brown dusting; the marginal area behind the undulate line is darkened with black strigiform spots above 
obesula.
