150 REPORT OF THE COMMISSIONER OF AGRICULTURE. 



species of Lophyrus or the Larch Nematus. It is possible that the fly 

 escapes from the cocoon in the autumn, but as a rule it without doubt 

 passes the winter in the cocoon, the fly making its appearance in the 

 late spring and early part of June, specimens having been found dead 

 in the breeding-box in the middle of May. 



DESCRIPTION. 



The larva. The "body is long, broader than the head ; pale pea-green ; of the color 

 of the leaves of the spruce among which it feeds. The head, is smooth, of the same 

 color as the body, with a dark patch extending upward behind each eye. Body not 

 spotted, but with a dorsal dark green stripe, bordered on each side"with whitish 

 glaucous green. Along the body is a lateral conspicuous broad white stripe, the stripe 

 much scalloped below. Body beneath, and abdominal legs, uniformly green ; thoracic 

 legs pale honey yellow, except at base. Length 17 mm . 



Cocoon. Of the usual oval cylindrical form ; of a pale horn color, of the usual 

 density, the walls being opaque. Length IS* 1 " 1 ; diameter 4 mm . 



The saie-fly (imago) [2 females]. Antennas 9-joiuted; flagellurn minutely hirsute, 

 7-jointed, the two basal joints of flagellum equal in length; head and body dull amber 

 yellow (testaceous) ; eyes black ; ocelli situated in a dark-brown patch ; a black 

 irregularly triangular spot above the insertion of each antenna, being situated in a 

 pit between the eyes and the intier edge of the broad orbits. A single minute trian- 

 gular black spot between the antennae ; clypeus, labrum, and palpi pale dull amber 

 (testaceous), concolorous with the head ; the mandibles dark at tips. 



Prothorax above not spotted. Mesonotum with three longitudinal, dark, broad 

 stripes ; prajscutum dusky reddish brown, pale on the sides ; on the middle of each 

 half of the scutum a broad blackish band reaching the front edge, but not extending 

 posteriorly behind a point parallel with -the apex of the scutelluin. Behind and be- 

 tween the ends of these dark bands are two small dark spots. Scutelluin on the 

 posterior half dark brown*; the inetascutum is black. Sides of the thorax and beneath 

 pale faded amber (testaceous), with a triangular black spot on the sides of the 

 prothorax below and in front of the wings. 



Abdomen of the same color as the rest of the body, but on the sides and beneath 

 with a greenish tinge ; above black, especially towards the base, next to the thorax ; 

 the segments above being banded transversely with black on segments 1-8, the bands 

 growing shorter (transversely) behind, until on the 8th segment the dark band is 

 scarcely wider than long ; the black bands extend on each side of the front edge of 

 each segment, forming a point on each side. Under side of nieso- and metathorax a 

 little dusky. 



Fore and mid die pair of legs testaceous; extreme tips of tibiae and tarsal joints with 

 a very narrow black ring ; last tarsal joint with the pad (pulvillus) and end of claws 

 dark. Hind legs : femora in color testaceous ; tibiae a little dusky, paler towards the 

 femora ; all the tarsal joints equally dusky. Ovipositor at base reddish horn color, 

 tip blackish. Wings with the veins blackish brown ; costal edge paler ; stigma dark 

 testaceous ; 4 subcostal cells, the 1st or innermost 4-sided, subquadrate. Length of 

 antenna 5 mm j length of body without antennae 8 mm ; length of a fore wing 8 mm . 



NOTE. This agrees in all respects with Mr. Norton's description of Nematus integer 

 Say, var. a (Trans. Amer. Ent. i, 216). It is recorded from Maine, Massachusetts, 

 Connecticut, New York, Pennsylvania, and Indiana. It thus seems to be a widely 

 distributed species. It is closely allied to Say's JV. vertebratus and to Norton's JV. trili- 

 neatus, but the pale fore and middle tarsi and the greenish tint distinguish it. The 

 description of the larva is taken from Bulletin 7, U. S. Ent. Comm., p. 234, No. 20. 



THE HEMLOCK GELECHIA. 



Gelediia abietisella, n. sp. 



Order LEPIDOPTERA ; family TINEIDJS. 



[Plate III, Fig. 2; Plate XIII, Figs. 7, 7a, 7&.] 



During the spring of 1883, the hemlock trees, large and small, in the 

 vicinity of Providence, E. I., were observed to be much disfigured by 

 the attacks of a small Tineid worm, causing sere and dead patches of 

 leaves on the smaller branches and twigs of both large and small trees.
