on each side of the body : the feelers are black towards the tips, 

 and much longer than the body : the eyes and the tip of the 

 mouth are black : the nectaries have black tips, and are nearly 

 one -fourth of the length of the body : the legs are pale yellow ; 

 the knees and the tips of the shanks are black. 



The winded male. This appears in the autumn and pairs with 

 the oviparous female at the end of October : it is deep black : the 

 abdomen is sometimes dark red with a black line along the mid- 

 dle ; it has a white bloom beneath ; the feelers are slender, and 

 much longer than the body; the fourth joint is much shorter 

 than the third, but more than half its length ; the fifth is shorter 

 than the fourth ; the sixth is about half the length of the fifth ; 

 the seventh is a little longer than the fourth : the nectaries are 

 nearly one-fifth of the length of the body : the thighs towards 

 the base, and the shanks except their tips are dark yellow : the 

 wings are very much longer than the body ; the wing-ribs, the 

 rib-veins and the wing-brands are pale brown ; the second vein 

 diverges rather more from the first than it does from the third ; 

 the first fork of the latter vein begins a little after one-third, and 

 the second beyond two- thirds of its length ; the fourth vein 

 is much curved near its base, but nearly straight towards its tip : 

 the angle whence it springs is slight. 



It sometimes couples also with the oviparous female of Aphis 

 Mali. 



Both these species very abundant in the autumn of 1846, but 

 very scarce during that season in 1847.

The vivipai'ous wingless female. This appears on the spindle- 

 tree (Euonf/mus europceus) in April : it is black, oval, convex, 

 short, broad, very plump, and covered with a white bloom : tlie 

 feelers are white, and about one-third of the length of the body ; 

 their tips are black : the nectaries are about one-fifteenth of the 

 length of the body : the legs are rather short, the shanks are 

 white with black tips ; the fore-shanks are dirty white with brown 

 tips. The young one is like its mother, but more flat and 

 linear, less intensely black, and without bloom ; its limbs are 

 blackish green, and at the moment of its birth its body is dark 

 green. The front of the head is slightly convex, and not notched ; 

 the first and the second joints of the feelers are not angular ; the
