inner vein it juts backward, forming a very acute angle, as it does also in 
a less degree in crossing most of the other veins. Extending across the 
three lines of the post-medial band, in the space between the third and 
fourth veins,'are two very slender black lines, which are united at their 
ends, forming a very narrow, elongated ellipsis, its anterior end very acute 
and reaching almost to the stigma. And parallel with this on its inner 
side, in the space between the fourth and fifth veins is a similar ellipsis, 
which is less than half the size of the outer one. These ellipses some¬ 
times appear merely as gray streaks, the black lines along their edges 
being obsolete, that along the outer edge of the outer one being most 
prominent and near its forward end widened into a small oval spot. For¬ 
ward of the hind margin is a coal black line, the sub-terminal, the most dis¬ 
tinct arid conspicuous of all the marks upon the wings. It is waved towards 
its inner end, conforming to corresponding but more slight curvatures of 
the third line of the post-medial band, with which line it is parallel through 
its whole length, a narrow brown space intervening between them. It is 
frequently deflected forward as it crosses the fourth vein, and it here ter¬ 
minates in the hind end of the elongated ellipsis. Behind this line, extend¬ 
ing along the border of the wing near its extreme edge, is a white line, 
the space between it and the black line being clouded with bluish gray. 
Finally, upon the brown ground at the apex of the wing is an oblique coal 
black line, extending from the tip forward and inward to the post-medial 
band, where it ends between the second and third veins. Its hinder por¬ 
tion is margined omits outer side by a pale streak, and where it crosses 
the second vein it curves forward and forms an acute angle. The fringe 
is short and brown, alternated with small gray spots placed half way 
between the ends of the veins. 
The under wings are blackish at their base, and have a broad, gray hind 
border, all their middle portion being dull white, and crossed by four black 
bands. The anterior baud is curved, and is commonly united with the second 
band inside of the middle, and again at its inner end. The second and third 
bands are parallel or slightly recede from each other towards their outer 
ends, their inner ends being usually curved almost to a half circle, with the 
concave side facing forward, the second band being widened and often 
becoming double in the middle of its curvature. Through the remainder of 
their length these bands are zig-zag or composed of arrow heads united at 
their ends, which form acute points projecting backward upon each of the 
veins. The fourth band is broader than the others, but towards its inner 
end it tapers and gradually becomes slender, its outer end being curved 
forward. It is parallel with the hind margin, and forms a border to the 
gray color of the hind part of the wing. The fringe is short, and of a brown 
color alternated with white, and becoming wholly white at the inner angle. 
On their undersides the upper wings arc dull brownish gray, more clear 
gray along the outer border, and are crossed in their middle by two ob¬ 
scure dusky bands, sometimes with a third band very dimly perceptible 
between them. These bands, as is particulary obvious in the hind one, are
