 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 tiie 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 and 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 tip forward and inward to the post-medial 

 band, where it ends between the second and third veins. Its hinder por- 

 tion is margined on the enter side by a pale streak, and where it crosses 

 the second vein it curves forward and forms an acute angle. The friiigo 

 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 dnll white, and crossed by four black 

 bands. The anterior band 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 their upper wings are 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 particularly obvious in the hind one, are
