220 FEATHER-WING MOTHS. 
tinge of coppery-red; the posterior part of the thorax is white. 
The fore-wings which have a deep brownish or coppery 
color with a metallic lustre and a few short silvery-white 
lines, are cleft down the middle about half their depth; this 
division, as well as the outer edge, is fringed The hind- 
wings, which resemble the fore-wings in color, are cleft into 
three parts, of which the posterior one is almost linear; all 
are deeply fringed. The antenne are ringed with silvery- 
white, and spots of the same color are also found upon legs 
and body, the latter having the same color as the wings. 
When at rest the wings are closed in a very peculiar fashion. 
The caterpillars of this moth are found full grown 
towards the middle of June; they are then about four-tenths 
of an inch long, of a pale yellowish-green color, streaked.

with pale yellow, and with transverse rows of shining 
tubercles,from each of which rise from two to six spreading 
hairs of a yellowish-green color. The small head is pale 
green, with a faint brown dot oneach side. The caterpillar 
spins a loose web between leaves, and in it changes to a 
pupa, which is suspended somewhat like the chrysalis of 
diurnal butterflies, which it also resembles, not being 
rounded as are most of the pupz of moths but being quite 
angular. It is less than three-tenths of an inch long, 
pointed behind, enlarging gradually towards the front, 
where near the end it slopes abruptly to the tip. Itis ofa 
pale green color, with a darker green line along the back, 
margined oneachside with a whitish ridge; the pupa is more 
orless hairy. Before the perfect insect escapes the pupa grad- 
ually assumes adarkercolor. The insect isshown in Fig. 207. 
At present this insect, which feeds also upon the black- 
berry, is not common enough to cause injury.
