and Rhode Island in September. It feeds between the leaves, drawing 
them together with silk threads. When about to pupate it turns over 
a portion of the leaf nearly an inch long, lines the interior of the cell 
thus made with silk, and the moth appears the following spring. We 
have compared the moth with a type specimen sent to us by the late 
Prof. P. C. Zeller several years ago, and now in the museum of the Pea- 
body Academy of Science, Salem, Mass., and it is undoubtedly that 
species, though the row of blackish dots so distinct in the fresh speci- 
men reared by us is not to be seen in the type specimen ; otherwise it 
agrees exactly with thelatter. It is not an uncommon insect, but, so far 
as known, more curious than destructive, though it may at times disfig- 
ure the leaves of valuable shade trees. 
The larva.—Head large, broad, and flat—as broad as the prothoracic segment; pale 
horn or whitish color, surface rough; in front crossed by two dark reddish-brown broad 
lines which form two large shallow scallops; the front line extends along the sides, 
including the eyes and the front edge of the clypeus; the other is broader, forming two 
scallops and crossing the apex of the clypeus. On each side of the head below the 
front line is a short, nearly straight, brown-black line not reaching as far as the eyes. 
The median suture of the head is rather deeply impressed ; the vertex on each side is 
a little swollen and marked with eight or nine dark reddish-brown more or less con- 
fluent spots. The posterior edge of the head is edged with black-brown. The body 
is somewhat flattened, pale pea-green, a little paler than the under side of the leaf. 
Prothoracic segment without a shield, but broad, flat, and green like the rest of the 
body. On the sides of the three thoracic segments is a dark tubercle tinged with 
reddish bet&veen, forming a lateral thoracic line. No dorsal tubercles, but pale hairs, 
as long as the body, arise from minute points, which are obscurely indicated. 
Length, 23™™, . 
The pupa.—Body very thick and stout; the head broad, and the abdomen short and 
thick; the end of the body very blunt, the tip broad and obtuse, somewhat tubercu- 
lated, not spined. The wings reach to the end of the fifth abdominal segment, and 
on the under side of the sixth and seventh segments are two dark, ventral, small cal- 
losities ; the tip is broad, truncated, rough, anddark. Length 10™™; thickness 3.5™™, 
The moth.—A very large species for the family to which it belongs. Head with the 
scales between the antennie and on the vertex loose and thick, not smooth as in Ge- 
lechia. Palpi long and slender, smooth, the third joint very long and slender, over 
one-half as long as thesecond, It is so large and the fore wings so broad and oblong, 
that at first it might be mistaken for a Tortrix. 
Body and wings snow-white. Fore wings snow-white with two smoky, twin dots 
at the base of the wing near the costa; two smoky spots inside of the middle of the 
wing on the internal edge. Beyond the middle of the wing are five or six indistinct, 
pearly, smoky spots, the central one apparently forming the discal dot. Two faint, 
curved, smoky lines parallel with each other and with the outer edge, neither of them 
reaching the costal edge of the wing, and the inner less than one-half as wide as the 
outer. On the outer edge of the wing, on the white fringe, is a row of about five con- 
spicuous dark brown spots; the base of the fringe is smoky, forming a faint line. 
Body, hind wings, abdomen, and legs snow-white ; antenne light brown. On hinder 
part of the thorax, very distinct when the wings are closed, is a large prominent tuft 
of broad brown scales, which send off different metallic colors, especially steel-blue. 
Length of body 9-10™™ ; of fore wing 11™™; expanse of wings 24™™,
