b. JSTovanglioe. —This variety differs remarkably from the normal forms 
of Iiapce in the color of both surfaces of the wings; these, if we 
except the dusky markings, are of a sulphur-yellow,'approaching 
in depth of color the wings of the Earema Lisa. 
3. P. Vjcnosa. 
Above, white tinted with very pale greenish-yellow; base of all 
the wings black, and costal border of primaries with a black band, 
extending about half its length; extremities of upper nervules of 
primaries broadly margined with black scales, with a spot of the 
same color in the middle of the space between first and second in¬ 
ferior nervules; a black dot at the tips of the nervules of secon¬ 
daries. The female differs from the male in having nearly all the nerv- 
ures on upper side of primaries somewhat bordered with grayish 
scales, and the extremities of the lower nervules almost equally 
with the upper; but most characteristically by the presence of a 
band of grayish scales along the posterior border of primaries, 
which is bent abruptly upwards in the direction of the spot in 
the space between first and second inferior nervules, and continues 
to third inferior nervule, sometimes interrupted at the angle. 
Beneath, as in the darker forms of P. oleracea , with the ground 
color slightly more highly colored than the upper surface; the nerv- 
ures of the secondaries being heavily, and those of the primaries 
more narrowly bordered with grayish scales, with a saffron-colored 
spot at the base of costa of secondaries. Antennae black, with 
incomplete white annulations interrupted above; tip of club yel¬ 
lowish; body black, with whitish hairs beneath; the wings expand- 
• from 1 . 5 to 2 inches. (Scudder.) 
a. Marginalis. —This species is most closely allied to the preceding, 
(P. venosa.) The ground color is as in venosa , but almost devoid 
of markings; base of all the wings black; costal border of pri¬ 
maries with a narrow black band, extending about half its length; 
a few grayish scales at the tip of wings; outer edge of primaries 
and posterior edge of secondaries with a very fine black line, 
slightly swollen at the tips of the nervules; fringe white; beneath, 
as in P. venosa , with the secondaries and apex of primaries more 
yellowish; males and females alike in their markings. 
Body black with some white hairs above, and a considerable 
number of yellowish-white ones beneath; antennae as in P. venosa: 
The wings expand two inches. 
(Scudder.) 
4. Monuste — male. —Upper surface of primaries white with a black 
border, wider at the summit, serrated-within. Upper surface of 
secondaries entirely white in the males. Under surface of pri¬ 
maries white, with the border pale brown or yellow ochre. 
Under surface of secondaries yellow ochrey, more or less pale, 
with the border pale brown, and a saffron spot at the base. 
The female has an arcuated black line on the middle of the pri¬ 
maries, and a marginal series of black triangular spots in the sec¬ 
ondaries.
