INSECTS INJURIOUS TO THE JUNIPER. 2AT 
The adjoining engraving well represents this singular mimetic form, 
which so closely resembles in form and color the smaller twigs of the 
juniper. Two of the caterpillars are represented, one holding itself out 
from the stem by means of its two hinder pairs of feet, while the other 
clings close to the stem. It is nearly-an inch and 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 falling off of ‘ 
the leaves of the juniper. 
The moth may be known by the faleate 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 fore wings 
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. 
The moth.—It has unusually faleate fore wings. 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 antennie 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, fol- 
lowed by a curve inwards on the submedian vein. The 
discal dot is small, black, but distinct. Just beyond the F16. 95.—Moth, larva, and chry-

deeper in tone next the line. The onter 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, end- 
ing 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, giving it a 
‘peculiar silky, glossy appearance,, suffused with © 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, but the line disappears before reach- 
ing the hind edge, which is whitish. The black stripe sent out from the angle of the 
line, and reappearing on the hinder edge of the apex of the wing, is much as above.
