walnut, butternut, and thorn are generally given. Though feeding 
on such a gieat number of trees, and being found over so wide a range 
of country as it is, no complaint has been made so far as I am aware 
of its occurring in sufficient numbers to do a great amount of damage 
ihe moths leave the cocoons in May or the fore jiart of June and de¬ 
posit their eggs on the under side of leaves from which the caterpil- 1 
lars hatch in ten or twelve days. The worm moults five times com¬ 
ing to maturity in September. When full grown it is a large apple- 
green caterpillar, “fleshy, striped obliquely with white on the sides 
with angulated segments on which are tubercles, giving rise to a few 
short hairs.” It spins a compact oval cylindrical cocoon about an 
inch and thiee quaiters long, the outside of which one or more leaves 
are fastened as though parted, in which it soon changes to a chrysilis. 
in trie autumn ttics© cocoons lall to the ground with the leaves. 
The moth expands from five to six inches, and has the antenn© of 
the males broadly pectinate ; the female less so. The wings are dull 
ochre-yellow, more or less clouded with black in the middle. Near 
the middle of each wing is a transparent, eye-like spot, divided trans¬ 
versely by a slender line. This spot is circled by a yellow and black 
line, the latter supplemented by a lilac line on the side next the 
base. In the hind wing the black on the side next the base is wider 
than the transparent spot, and the lilac is next to the yellow. Near 
the margin is a dusky band, edged with reddish white “in the outer 
part, and two black spots near the apex, supplemented with the 
same. Costa, gray. 
Actias luna, Linn.—The Luna Moth. 
The Luna silkworm, the caterpillar of this species, feeds princi¬ 
pally k on walnut and hickory, but is also found on sweet gum, beech 
birch, and even willow and plum,” and it resembles the Polvphemus 
silkworm. It is a paie and very clear, bluish green caterpillar, with 
a yellow stripe on each side of the body, and the back crossed between 
the segments by transverse lines of the same yellow color. On each 
segment there are about six minute, pearl-colored ivarts, tinged with 
purple or rose color, and from which arise a few short hairs. At the 
extremity of the body are three brown spots, edged above with yel- 
When full grown it draws together several leaves, fastens them with 
silken thieads, and spins inside the hollow a cocoon very much re- 
semohng the cocoon of the preceding species. Like the other, it falls 
to the ground with the leaves in the fall. As a silkworm this species 
can na v r e but little value, lor the reason that the cocoon is so compact 
and thin that it could be unwound with difficultv. 
The moth has an expanse of wings of about four and a half inches, 
die antennal pectinate, broadly so in the males. The hind wings, 
instead of being round, have the anal part extended into a broad 
tail, curving somewhat outward, an inch and three-quarters beyond 
the rest of the outer margin. In color the wings are delicate green, 
wun an eye-like spot on each wing, consisting of a small clear cen¬ 
ter the encircling colors being rare, yellowish and black costa, and 
collar purplish brown.
