and on the median vein, and anguiated outward slightly on the sub- 
median; it is distinctly prolonged on to the base of the hind wings. 
The second or middle line begins as a broad, triangular, costal patch, 
larger than that of the basal line, and curved around just outside 
of the simple discal dot (which seems, however, to form one side of 
a ringlet, of which the outer two-thirds are formed by the curve in 
the line). The line widens at the origin of the first median venule, 
where it approaches the outer line; it touches it just below the 
second median and then diverges on to the inner edge. The line is 
slightly scalloped. Outer line black, distinct, broadly sinuous, with 
three grand curves; between the costal edge and the last subcostal 
venule three unequal teeth, the largest and most acute just below 
the costa; below it and at the base a point on the second venule; 
from the third tooth the line sweeps around continuously to the 
third median venule, with a black point on each venule; below this 
the line curves regularly inward, pointed outward on the sub-median 
vein; a dull-brown, almost blackish shade borders this line. A sub- 
marginal, zigzag, distinct, white line, the scallops within filled with 
black. From each white point a narrow, dark streak connects with 
each black intervenular dot. A dark shade in the extra-discal inter- 
space. Fringe on both wings gray, faintly checkered with paler 
opposite the black dots. Hind wings pale within the extra-diseal 
lines; at the extreme base a black line; a straight shade just below 
the discal dot, which is black, linear, distinct. The third 1s narrow, 
black, distinct, nearly straight, pointed slightly outward on the costal 
vein, and with a very prominent tooth on the first sub-costal vein ; 
between the median vein and the inner edge a little curved inward. 
Beyond is a brown shade. A _ broad, sub-marginal, dusky shade, 
inclosing a zigzag, white line. A black, marginal, scalloped line. 
Beneath pale ash, with a very faint ochreous tint; discal dot on the 
fore wing three times as large as on the hind wings; middle area of 
the fore wings smoky. A very broad, marginal, blackish shade, 
leaving a whitish apex, and the adjoining portion of the fringe paler. 
On the hind wings the shade is narrower, disappearing at the imner 
angle of the wing, and leaving the edge of the wing vale. Both 
wings mottled with rather broad, transverse streaks. A _ distinct 
black band at the base of the abdomen; the hind edges of the second 
and succeeding segments dusky; the basal segments unusually white. 
Anterior pair of legs dusky, with narrow paler rings; hind femora 
thick, pale, with a pencil of hairs, as usual. The female is larger, 
alittle more dusky above and beneath, but with the same markings.” 
__ From related species, this may be distinguished, according to 
Dr. Packard, ‘‘by the very distinct line at the base of the abdomen, 
the basal ring beyond being unusually white, and by the under side 
of the wings having a broad marginal shade, while the third line on 
the fore wing is deeply- but quite regularly sinuate, and near the 
costa acutely dentate, while in C. humaria it is instead obtusely 
curved. It varies a good deal, especially in the tint of the brown 
shade accompanying the third line. It does not apparently vary 
much in size.” ‘The species is widely distributed, from Maine and 
Pennsylvania to Alabama, Texas and Nebraska, and is is said to 
feed likewise upon the leaves of the pear.
