550 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



traced two forming a vascular stripe, and two similar lateral stripes on each side. 

 On segment 1, anteriorly, are four dorsal white lines, posteriorly black ; segment 2 

 is black anteriorly, behind which are irregular black linings; segment 3 as the pre- 

 ceding one; on segments 5 and 10 the dorsal black linings assume a V-shape, the 

 apex resting on the suture and inclosing centrally two yellow-gfeen snbelliptical 

 spots, with a similar spot exterior to each within the superior lateral stripe. From 

 the first segment long whitish-brown hairs project over the head, nearly concealing 

 it; from the middle of the second and third segments whitish hairs project forward, 

 of which those on the latter segments are shorter and arranged somewhat in tufts, be- 

 neath which, when extended, some short stiff red hairs are seen ; laterally, below 

 the stigmata are two rows of fascicles of white hairs of unequal length, mingled with 

 a few longer brown ones, extended rectangularly with the body until to its middle, 

 whence the remainder are directed backward ; from the terminal segment white and 

 brown hairs, of greater length than elsewhere on the body, project horizontally, 

 brush-like, backward; short whitish hairs are scattered sparsely over the body. 



(The larva escaped before its description could be completed, and the remainder is 

 from memory.) On the vascular line on each segment is a tuft of black hairs about 

 0.06 inch long, the ends of which converge to a point. The prolegs project laterally, 

 almost hidden by the hairs. Veutrally is a broad fuscous stripe, (Lintner, Eut. 

 Contr., iii, p. 130.) 



20. Gaatropacha americana Harris. 



While the singular lappet caterpillar is found at times on the apple, 

 its native food plant is the oak and ash. It may be found on the trees in 

 September, when it spins its cocoon, the moth appearing in New England 

 early in the succeeding summer. In Georgia, according to Abbot, it 

 spins its cocoon in May, the moth appearing the following February. 



Larva. — Body large, broad, and flat, with hairs on the side spreading out so as nearly 

 to conceal the feet, the hairs arising from large lappets hanging from the side of 

 each segment, the first pair the largest ; upper side of the body gray, variegated with 

 irregular white spots and siJrinkled with fine, black dots ; in front are two trans- 

 verse velvet-like bands of a rich scarlet color, with three black dots on each band ; 

 underside of the body orange-colored with a row of diamond-shaped black spots ; 

 length 2| inches. — Harris. 



Moth. — When at rest it would be mistaken for a dry, brown, crumpled leaf, the 

 edges of the hind wings being much notched as are the outer and inner edges of the 

 fore wings; reddish-brown ; beyond the middle of each of the wings is a pale band 

 edged with zigzag, dark-brown lines ; there are also two or three short, irregular, 

 brown lines running backward from the front edge of the fore wings, besides a min- 

 ute pale crescent edged w\ th dark-brown, near the middle of the same. In the female 

 the pale bands and dark lines are sometimes wanting, the wings being almost 

 entirely of a red-brown color. The wings expand from 1| to 2 inches. (Harris.) 



21. Tischeria quercivorella Cham. 



Mr. y. T. Chambers describes this moth {f T. quercitella, Frey, nee 

 T. quercitella, Clem.) as follows: 



I have not seen the specimens from which Frey described his species, nor the single 

 imperfect one from which Clemens prepared his description. Frey thought his speci- 

 mens belonged to Clemens' species, but Frey's description applies sufficiently well 

 to the four males and two females before me, and which I can not reconcile with 

 Clemens' account of his species. In quercivorella, the face, palpi, and antenme are 

 very pale lemon-yellow, the vertex being darker, as dark as the forewings. Clemens
