908 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
out from the stem by means of its two hinder pairs of feet, while the 
other clings- close to the stem. It. is nearly au inch aud a half long 
and less than a line in thickness. Its body is quite rough, with a few 
prominent tubercles, in size and form resembling the scales left by the 
tailing oil of the leaves of the juniper. 
The moth may be known by the falcate fore wings, by the three dark 
spots at the inner angle of the fore wing, and the dark transverse lines; 
in the females the inner line of the forewings is 
much curved and sinuate. 
The caterpillar was received from Norwich, 
Conn., early in June, and on the 17th changed 
into a beautiful pea- green chrysalis, the moth 
appearing the 29th of the same month. 
I have beaten the males and females of this 
moth out of white pine trees as late as October 
5, at Providence, and they probably lay their 
eggs at that time; perhaps it is double-brooded. 
The moth. — It has unusually falcate forewings. The 
ground color of the upper side of the wings is a pale 
fawn-brown, with a rusty but no purplish tinge, as in 
some other species of the genus ; but the body and 
antennae are pale fawn-brown. The fore wings at the 
base are fawn-brown, but with rather thick-set black 
scales, especially towards the inner line. This line is 
curved zigzag, rusty fawn-brown, and is very distinct; 
it begins at the basal third of the costa, and curving 
around opposite the discal dot, in a generally oblique 
direction, ends nearly as far from the base of the wing 
on the inner edge as on the costa ; below the median 
vein the line is acutely zigzag, forming a tooth just 
below the lowest median veinlet, followed by a curve 
inwards on the submedian vein. The discal dot is 
small, black, but distinct. Just beyond the dot the 
wing inside of the outer line is rusty, becoming deeper 
in tone next the line. The outer line is straight, white, 
narrow, but sharply defined, and forms an acute angle 
opposite the apex, being reflected back on the costa. 
The line is shaded externally with dense black scales, 
becoming thinner towards the outer edge of the wing. 
From the apex of the bend on the outer line starts 
a black streak, which is interrupted in the middle, but ends on the lower side 
of the hooked apex of the wing, which is unusually long and large. The fringe is 
rust-colored, with the edge white. The outer edge of the wing is deeply hollowed 
out just below the apex, but below is full and convex. The hind wings are like the 
fore wings, but without the inner line. The discal dot is distinct, and the outer line 
is straight, ending just before reaching the costa. There is a broad costal white area. 
The legs and under side of the wings are fawn-colored, densely speckled with black, 
giviug it a peculiar silky, glossy appearance, suffused with a very slight wine-colored 
tint. The surface of both wings is uniform; the discal dots are more diffuse than 
above, being more distinct on the hind wings. The outer line is white, distinct, 
broader than above, and bent at right angles upon the costa. bat the line disappears 
before reaching the hind edge, which is whitish. The black stripe sent out from the
