Seven specimens. The antennnc attain the tip of the stigma, and the 

 stigma is four times as long as wide, and very acute at both extremities. 

 Differs from Dr. Fitch's brief description in the antennae not being entirely 

 "black", in the honey-tubes being black, which are not specially referred to 

 by Fitch, but should be "red" as he makes the ground-color "red'', and in the 

 stigma being pale fuscous-brown not "yellowish". The first of these differ- 

 ences generally becomes evanescent in the dried specimen; the second is 

 probably a mere oversight. Dr. Fitch's insect occurred, as before stated, on 

 lludbeckia laciniata, Solidago serotina and S. gigantea. 



Aphis bella n. sp. — Oak-leaves? Bright yellow. Eyes black: antennse with the 

 tip of joints 3 — 6 black. Prothorax as long as the head, with a lateral black vitta; 

 thorax with a black vitta extending from its anterior angle to the base of the 

 front wing. Honey-tubes scarcely as long as the tarsi, generally immaculate, 

 sometimes tinged with fuscous. Legs long, black except the base of the femora 

 and the coxae. Wings hyaline ; front wings with the entire costa as well as its ner- 

 Yures black to the tip of the stigma, whence there extends a marginal dusky vitta, 

 as wide as the costa at base and middle but tapering at tip, nearly as far as the 

 middle branch of the third discoidal vein; this vitta covers the entire length of the 

 4th or stigmal vein, which terminates halfway between the tip of the stigma and 

 the apex of the wing, is slightly and gradually curved, and encloses a marginal 

 cell not wider than the costa; hind wings with a costal dusky vitta extending to 

 the tip of the wing, the subcostal vein sometimes black; remaining veins of both 

 wings slender and pale-dusky, narrowly bordered with subhyaline where they tra- 

 verse the terminal dusky vitta of the front wing. Length to tip of wings .15 inch. 



The antennae attain the middle of the stigma when the wings are ex- 

 panded, and the stigma is rather more than three times as long as wide, 

 not very acute at each end. Three specimens beaten off oaks on two sep- 

 arate occasions. The marginal cell is one-half smaller than in any other 

 species known to me. A yellow larva, with an irregular oval black spot 

 enclosing a central yellow space on the abdomen, occurs rather abundant- 

 ly on the oak, and probably belongs to this species; but I could never find 

 any winged individual in company with it, and failed in an attempt to 

 breed them. 



Aphis vitisi Scopoli. n. U. S. sp. — Tame grape-vines. Blackish. Antennae mod- 

 erate, linear. Honey-tubes 2i — 3 times as long as the tarsi. Legs moderate, pale 

 greenish; knees, tips of tibiae, and tarsi dusky. Wings hyaline, veins brown, the 

 3rd discoidal hyaline at its extreme origin; stigma dark dusky-brown. Length to 

 tip of wings .11 — .12 inch. 



Sixteen specimens, found in company with many larva?. The antennae 

 attain the middle of the stigma when the wings are expanded, and the 

 stigma is three times as long as wide, not hunched externally, and mod- 

 erately acute at each end. Not unlike Aphis mali when dried, but readily
