and Khode 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 the latter. 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 protboracic segment ; pale 

 born or whitish color, surface rough ; in front crossed by two dark reddish-brown broad 

 lines which form two large shallop- scallops ; the front line exteuds 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. 

 Protboracic 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 between, 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 mm . 



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 underside of the sixth and seventh segments are two dark, ventral, small cal- 

 losities : the tip is broad, truncated, rough, and dark. Length 10 mm ; thickness 3.5 mm . 



The moth. — A very large species for the family to which it belongs. Head with the 

 scales between the antennae 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 the second. 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 casta ; 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 aud with the outer edge, neither of them 

 reaching the costal edge of the wing, aud the inner less thau 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, aud legs snow-white ; antenna? 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 mm ; of fore wing ll mre > ; expanse of wings 24 mm .
