line white, proximally with black sagittae; behind it the marginal area is dusted with white. Hindwing brown, 
towards the margin darker with white fringes. California. 
P. meditata Ort. (14 k) is similar to leucogramma , larger, more monotonously brown, with much 
less contrasting transverse lines and without the black median shade; the marginal area behind the undulate 
line is darker, dusted with grey, with darker veins. Hindwing darker brown. Canada, Eastern States as far 
as Virginia and Mississippi, Kansas. — The larva is of a dirty reddish-brown with roundish, darker dorsal spots 
in a lighter ground. It lives polyphagous. 
P. brachiolum Harv. (15 a) has more grey forewings dusted with a blackish brown, with double 
dentate transverse stripes filled up with grey, and small maculae surrounded by black; the postmedian area 
is grey like the undulate line which is marked black on both sides. Hindwing brownish-grey, towards the base 
lighter. Texas, Arizona. 
P. mohosa Dogn. (15 a) is a very small species with whitish forewings suffused with red-brown 
and blackish-brown, with double anterior and single dentate posterior transverse lines, the latter distally bor¬ 
dered with white. Maculae in white rings, pupilled red-brown, the reniform macula in the centre white, on 
the median prolonged proximad; undulate line white, the marginal area behind it greyish-brown. Ecuador 
(Loja). 
P. orizabena Schs. (15 b) is on the forewing blackish-brown, tinted purple reddish and with a grey 
reflection; the indistinct double transverse lines are filled up with a somewhat lighter reddish colour, the median 
area between them is darker; maculae small, the ring-macula grey, the reniform macula in a reddish-pink ring 
with a white spot at the distal edge; the undulate line is composed of white dots on black longitudinal streaks. 
Hindwing yellowish-brown. Mexico (Orizaba). 
P. rubrifusa Htnps. (15 a) is dark grey, strewn with black, with a slight purple tint, the subbasal 
and postmedian areas being reddish, both the folds in the discal area deep red; anterior transverse line double, 
the posterior line single, dentate, distally marked whitish; the maculae are small, reddish, in white rings; the 
undulate line is reddish, proximally with small brown sagittae, distally shaded dark. Hindwing light brown, 
towards the margin darker. New Mexico. 
P. umbrosa Sm. (15 b) is somewhat like rubrifusa, more grey, dusted with dark brown, with a darker 
discal area, the transverse lines as in rubrifusa ; the reniform macula is on the median somewhat proximally pro¬ 
duced, before and behind it reddish dusting; an undulate, darker median line is traceable; undulate line white 
proximally scarcely darker; hindwing brownish-grey, veins and margin darker. From Colorado and Arizona. 
P. hanhami B. & McD. (14 k) has light brown forewings strewn with blackish, with rather indistinct 
markings, the anterior transverse lines double, the posterior line single, behind it a row of black dots on the 
veins; between the small, dark encircled maculae a dark median shade extends, being enlarged into a round 
dark spot below the reniform macula from where it extends undulate to the proximal margin; behind the undulate 
line the marginal area is darkened. Hindwing smoky grey with a dark discal spot. Vancouver. — semicamea 
B. & McD. (15 a) is the form occurring in Central and South California, in which the ground-colour is a light 
flesh-coloured red, whilst the black dusting in the discal and marginal areas is reduced. 
P. gnata Grt. (15 a). Forewing dark grey, dusted with yellowish-brown, with double transverse lines, 
both only undulate, not dentate; the small coniform macula is encircled with black, the upper maculae of medium 
size, in whitish rings and surrounded with black, the ring-macula obliquely elliptical; from the cell-end a slight 
median shade extends to the proximal margin; behind the postmedian line there is a large light spot at the 
proximal margin; the undulate line is light, on the discal and submedian folds bent proximad, the marginal 
area behind it darkened. Hind wing white with brownish veins and margin. New Mexico, Arizona. 
P. surgens Dyar (15 a) seems to approximate gnata ; forewing much narrower and greyer, only in 
the discal and subterminal areas dusted with brownish, behind the subbasal transverse line at the proximal 
margin a blackish shade, both the middle ones approaching each other at the proximal margin, finely dentate; 
above the anal angle a large, oval, yellowish spot; the coniform macula is a black spot, the upper maculae are 
yellowish-brown, in lighter rings; the undulate line forms two proximally directed bows which are distally 
edged with black, proximally accompanied by 3 small sagittae; marginal area dusted more with grey. Hind¬ 
wing whitish, at the margin brownish, in the $ entirely darkened. Mexico (City). 
P. miilleri sp. n. (15 b) is allied to surgens , larger, with broader wings and with the same serrate 
antennae in the male, the greyish-white ground densely dusted with brown and strewn with black, postmedianly 
on both folds brightened up with ochreous-reddish, with black double transverse lines, the anterior line filled 
up with a lighter grey and submedianly forming a large bow projecting towards the margin, the posterior line 
much more indistinct, subanally behind it a large, oval, light spot, the upper distal bordering of which terminates 
as an oblique yellowish-white streak into the anal angle; the coniform macula is a small black spot, the upper 
maculae are filled up with a yellowish brown, in whitish rings and surrounded with black, the ring-macula 
obliquely elliptical, the reniform macula proximally concave, on the median pointedly extended proximad; 
the undulate line forms two similar, though more shallow bows than in surgens , behind it white strewing, the 
most intensely subapically, the upper bow being there bordered with black in the lower half; fringes brown 
speckled with ochreous whitish. Hinclwing in both sexes of a dark brownish grey, fringes in the distal halves
