of small black spots on each side: the feelers are black, and 
nearly as long as the body: the mouth is pale yellow; its tip 
and the eyes are black: the nectaries are spindle-shaped, dull 
yellow, darker towards the base and at the tips, and hardly 
one-fifth of the length of the body: the legs are pale yellow; 
the hind-thighs, excepting the base, the feet, and the tips of 
the other thighs and of the shanks, are black: the wing-ribs, the 
rib-veins, and the wing-brands are pale yellow; the other veins 
are pale brown. This, like its predecessor, the wingless female, 
almost disappears during some part of the summer and the au- 
tumn, but a solitary little individual may still be seen here and 
there beneath the leaves. | 
The oviparous wingless female. This lives in October and in 
the beginning of November, when it lays its eggs on the shoots 
of the currant : it is elliptical, olive-green, mottled with pale yel- 
low: there is a large green spot on each side of the abdomen by 
the nectaries : the feelers are yellow, black towards the tips, and 
longer than the body: the mouth is pale yellow; its tip and the 
eyes are black: the nectaries are pale yellow with black tips, 
and as long as one-fourth of the body: the legs are pale yellow; 
the knees, the feet, and the tips of the shanks are black; the 
hind-shanks are shaded with pale brown. 
1st var. Yellowish green. 
2nd var. Yellowish white. 
3rd var. A black band round the middle of each hind-shank. 
The winged male. It pairs: with the oviparous female before the 
end of October. The head and the chest are black: the abdo- 
men is dull yellow, with a few short slight bands across its back : 
the feelers are rather thick till near their tips, and almost as long 
as the body: the mouth is yellow with a black tip: the nectaries 
are black, and as long as one-sixth of the body: the legs are yel-. 
low ; the hind-thighs, the feet, and the tips of the other thighs 
and of the shanks are black : the wing-ribs are yellow ; the wing- 
brands and the veins are brown. 
1st var. The fore-chest beneath its borders above, and the ab-

dots on each side: the nectaries are as long as one-eighth of the 
body : the hind-thighs are pale yellow towards the base.

This is a very elegant insect : it is hairy hke A. Avellane and 
A. tetrarhoda, but in other characters it differs widely from these 
two species. It feeds from February to October on Galeopsis 
tetrahit, G. bifida, Lamium album, L. purpureum, L. amplexicaule, 
Polygonum Persicaria, P. lapathifolium, P. hydropiper, P. laxi-
