The viviparous ivingless female. The body is black, oval, hairy, 

 velvet-like, and prettily mottled with white : the abdomen beneath 

 is almost white : the feelers are filiform, black, hairy, pale yellow 

 towards the base, and nearly half the length of the body ; the 

 fom-th joint is much less than half the length of the third ; the 

 fifth is much longer than the fourth ; the sixth is longer than the 

 fifth ; the seventh is extremely short : the front is convex : the 

 mouth is black, yellow towards the base, and reaches beyond the 

 hind-hips : the legs are black, stout, and hairy ; the base of the 

 thighs and the shanks except their tips are yellow; the shanks 

 and the second joints of the feet are slightly curved. When 

 young it is grayish black and linear : the mouth projects some 

 way beyond the tip of the abdomen : the feelers and the legs are 

 white ; the knees, the feet, and the tips of the shanks and of the 

 feelers are black. 



1st var. The body is brown, shining, and mottled with gray 

 and black down : the feelers are nearly white ; their tips are 

 brown : the nectaries are black : the legs are pale yellow ; the feet, 

 the tips of the thighs and of the shanks and the base also of the 

 latter are black. 



The viviparous winged female. It acquires wings in the begin- 

 ning of June, and is then dark brown and covered with white 

 powder : the feelers are tawny, and rather less than two-thirds of 

 the length of the body ; the tips of the joints are brown : the eyes 

 are dark red and prominent : the mouth is tawny with a brown 

 tip and reaches the hind-hips : the legs are tawny ; the feet and 

 the tips of the shanks are brown ; the thighs also are adorned 

 with brown spots and rings : the wings are colourless, clouded 

 with brown, and longer than the body ; the wing-ribs, the wing- 

 brands and the veins are dark brown ; the rib-vein begins to widen 

 into the brand a little after half the length of the wing ; the brand 

 is rather long, and almost spindle-shaped; the angle near the tip 

 of its hind-border is very obtuse, the part thence to the tip is 

 slightly curved, and not near so long as that of A. viminalis, but 

 much resembles the termination of the brand in Aphis suhmacula ; 

 the fourth vein is slightly curved and rather long ; the third vein 

 is obsolete near its source ; it is forked before one-third and 

 forked again after two-thirds of its length ; the angles formed by 

 these forks are very acute ; the tip of the upper branch of the 

 second fork is very near the tip of the fourth vein ; the first and 

 the second veins are almost straight ; they are near each other 

 at the base, but very far apart at the tips.
