HICKORY CATERPILLARS. 315 



-edge of the wing; the two spots are sometimes almost connected by a light line. 

 The edge of the wing buft- white with black scales. Hind wings and abdomen slate- 

 colored. Length of fore-wing, 7™™ ; width, 1.5°*™ ; expanse of wings, about 15™"' 

 <0.60 inch). 



79. Lithocolletis carycefoliella Clem. 



This larva mines the upper side of the leaves of the hickory tree in 

 June, July, and September, making a white blotch, or an irregular 

 rather l)road tract when there is but one in the leaf, and not throwing 

 the leaf into a fold. Frequently there are several larvae in a leaf — in 

 one instance I counted twelve. The " frass " is deposited along the 

 middle of the mine. The perfect insects of the spring brood appear in 

 August ; from the fall brood I did not succeed in rearing the imago.

Larva. — The larva is flattened, and its physical characteristics are similar to those 

 of the second larval group. The head is light brown ; the body dark lead color, 

 becoming yellowish posteriorly, with the mammillae of the thoracic rings yellowish, 

 and a central spot of the same hue on the first; each ring on the dorsum with a dark 

 brown, shining macula, those on thoracic rings trapezoidal, the remainder oval ; on 

 the ventral surface the maculae are also dark brown, those on the fourth and fifth 

 rings being oval. (Clemens.) 



Moth. — Antennae silvery, annulated with blackish. Front silvery. Tuft and thorax 

 reddish orange. Fore-wings reddish orange, with three silvery bands, black-margined 

 exteriorly, the second about the middle of the wing, angulated, with the black mar- 

 gin broad and produced posteriorly on a whitish ground, nearly to the third, which 

 is somewhat interrupted in the middle ; the first midway between the second and the 

 base of the wing and also angulated near the costa. The apical portion of the wing 

 white, covered with dispersed black scales, with a few black scales on a whitish 

 ground, on the costa, between the last silvery band and the dusted apical portion ; 

 with two hinder-marginal lines, one the margin of the apical scales, the other a dark 

 brownish line in the cilia. Hind wings pale brownish-gray ; cilia gray, with a ful- 

 vous hue. (Clemens.) 



80. lAthocolletis carycealbella Chambers. 



81. Nepiicula carycefoliella Clem. 



This larva is found in the leaves of hickory late in July and early 

 in August. The mine is very like the preceding, but rather wider and 

 longer and not so tortuous, but nearly always recurved and with the 

 central "frass" line. 1 have taken a specimen as late as the 30th of 

 August, but at this date almost every mine found is untenanted. 

 (Clemens.) 



Larva. — The larva is pale green, with a dark green central line and brownish head. 

 It is nearly or quite cylindrical, diameter uniform, the anal segments pointed.

82. The hickory sack-bearer. 



Coleophora sp. 



This interesting sack-bearer was fouud feeding on the unfolding 

 leaves of Garya porcina at Providence, May 24. Its sack is flattened 

 elongate ovate, 3.5™™ in length ; the anterior end is square, a little 

 wider than the posterior end, which is more rounded. It is of a pale 

 light horn color.
