wards their tips brownish black. An oblique tawny yellow bond ending in white on 
the outer margin extends across the outer lobe near its base, and on the apex of the 
outer margin is a white stripe. The fringe along their inner margin ia blackish, with 
a few white hairs forming a small spot at its apex, another white spot forward of it, 
a larger one towards the base of the inner lobe, and a small one forward of the base 
of this lobe. The hind wings and their fringes are blackish brown, and the inner lobe 
near the middle of its inner side sends out some coal black scales forming a spot of 
this color in the fringe, with a faint ash gray spot immediately forward of it. Be¬ 
neath, the wings are blackish brown and the anterior pair have three equidistant 
white streaks on the outer margin, the first rather forward of the middle and the last 
on the apex; the outer lobe of the hind wings has a white spot near its tip. the inner 
lobe has a slight white spot on its apex and another on the middle of its inner mar¬ 
gin. The antenme are black with white rings, and on their under sides ash grey. 
The abdomen has white stripes on its under side. The legs are striped alternately 
with black and white and are banded with a broom-like tuft of black scales at each 
pair of spines. The spines are white, their bates, under sides, and also the tips of 
those on the middle shanks, black. The feet are white with a black band on the apex 
of each joint, and the first joint erf the two anterior pairs has a black stripe on its 
outer side. The wings when spread measure 0.80 from tip to tip. Taken the last 
of June on bushes in meadows. 
The Slender-lobed Plume (P. tenuidactylus) is of a dark tawny brown color 
somewhat tinged with coppery red, and on the fore wings has a white spot towards 
the base of each lobe, and often on the outer lobe a transverse white streak between 
the spot and the apex; their fringe is whitish, with a black spot in the middle and 
larger one at the apex of the inner margin. The hind wings are of the same color, 
their lobes very slender, the inner one thread-like, white, its fringes while with a 
broad black band near the lip. The legs are white, striped with black, the feet, and 
hind shanks with black bands. The antennm are white with a slender black ring to 
each joint. The abdomen is blackish, and at base on the under side silvery white. 
The wings when extended measure 0.60 across. This species is common upon brakes 
and other weeds growing in swamps in the middle of July. 
The Ashy Plume (P. cineridactylus) is ash gray throughout, of a darker tint 
upon the breast. The fore wings are sprinkled with blackish brown atoms, chiefly 
towards the inner margin and the base. The antennas have a pale brown ring on each 
joint, which is widely interrupted on the under side. The feet and shanks are whitish 
and the hind shanks have a faint brownish band at tip and another on the middle. 
The expanded wings measure 0.76. Taken the fore part of July, in yards around 
dwellings. . 
The Brown-bordfred Plume (P. marginidactylus) is tawny brown, the fore 
wings varied with white cloud-like spots, whereof there is one on the outer margin 
towards the tip and two on the inner margin, the apical and outer margins and a 
cloud like central space extending from the cleft inwards are of a t^rk brown color; 
fringe whitish, brown at the outer and inner apical angles, and a small brown spot 
beyond the middle of the inner margin ; under side and hind wings pale tawny brown; 
legs white, thighs, anterior shanks and apical third of the hind shanks brownish on
