£L few silk threads, or there is a regular tube of silk situated between 

 two leaves, the latter severed from their connection with 

 the branch, but held in place by silk threads, the leaves con- 

 sequently turning brown; the heads of the branches are 

 thus withered for about an inch, so that patches of the cran- 

 berry-bed are brown and withered. 



Body long and slender, tapering a little toward the head, 

 but more toward the tail. Head about three-fourths as wide 

 as the middle of the body. Pale testaceouSj with a few long 

 hairs. Mandibles reddish, dusky at tips. Ocelli blackish. 

 Prothorax unusually long, nearly as long as the head, elon- 

 gate lunate, with no markings on it, slightly wider than the 

 T^- head, but decidedly narrower than the succeeding segment. 

 ^ Body pale livid green, with six longitudinal pale-reddish 

 lines, broken and irregular toward the head, but more dis- 

 1 inct and wider toward the tail, so that the body looks darker 

 and rather reddish posteriorly. On the front edge of the 

 second and third rings a transverse row of six black minute 

 warts giving rise to a hair, and a seventh one low down in 

 the middle of the side. On the abdominal segments four 

 dorsal black warts, the two anterior nearer together than 

 the posterior, though not forming a decided trapezoid; on 

 side of ring another black wart in line with the fewo anterior 

 dorsal ones, and giving rise to a rather stout hair. Around

 r a n bV?r y and two median dorsal smaller warts. Beneath, livid-green- 

 Worm. jgij^ the three segments between the last pairs of feet with 



each a transverse straight row of minute black warts. 



The Oranberry-Vine Worm {Anchylopera vacciniana Packard). — 

 Our account of this insect is taken as follows 

 from our " Guide to the Study of Insects," 

 while the figures are engraved from original 

 drawing made by Mr. Emerton. 



Mr. Fish has discovered an undescribed spe- 

 cies which feeds on the cranberry, and which 

 we may call the Cranberry Anchylopera {A. 

 vacciniana). The moth is dark asli, the fore

enlarged. rcddish scalcs, with white narrow bands on the 



costa, alternating with broader yellowish-brown bauds, five of which are 

 several times larger than the others; from four of them irregular indistinct 

 lines cross the wing. The first line is situated just beyond the inner third 

 of the wing, and is often obsolete. The second line is the largest, and 

 is slightly bent once in the middle of the wing. There is a large brown 

 spot parallel to the costa, being situated on the angle. The third line 

 is oblique and stops before reaching the inner angle, and is forked on 

 the costa, while the fourth line is a short apical diffuse irregular line. 

 The apex of the wing is dark brown, and is a little more acute than 

 usual in the genus. The length of a fore wing is .28 of an inch. It 

 lays its eggs on the leaves during the month of August, and a new brood 

 of larvae appears in September, though they hatch mostly in the follow- 

 ing spring or early in June, and become fully grown in July. 



The larva seen from abov^e is much like that of Lozotwnia rosaceana, 

 but the head is a little larger in proportion to the rest of tbe body, be- 

 ing as wide as the body in its thickest part. The body is more hairy, 

 while the prothorax is' not dark. The chrysalis is rather slender, the
