Aphis Prunaria. 



The wingless viviparous female. The body is dark red and covered with a white 

 bloom, short, elliptical, and very plump : the antennae are black and nearly half the 

 length of the body : the eyes and the rostrum are also black : the legs and the tubes 

 are of the same colour, and the latter are as long as one-tenth of the body. 



The winged viviparous female. While a pupa it resembles the wingless insect in 

 colour, but is much more flat. 



In the beginning of June. 



Aphis prunina. 



The ivingless viviparous female. The body is grass-green, elliptical, and slightly 

 convex : the antennae are dull yellow and hardly more than half the length of the 

 body : the eyes are dark brown : the rostrum is dull yellow, with a brown tip : the 

 tubes are about one-twelfth of the length of the body : the legs are pale yellow ; the 

 tarsi and the tips of the tibiae are brown. 



At the end of April. 



Aphis ? 



The winged viviparous female. The body is black : the fore border, the hind bor- 

 der and the under-side of the prolhorax are reddish yellow, as is also the abdomen, 

 which has a black disk and a row of black spots on each side : the antennae are much 

 longer than the body : the rostrum is yellow, with a black tip : the tubes are dull yel- 

 low, slightly spindle-shaped, and nearly one-fourth of the length of the body : the 

 thighs are pale yellow, black from the middle to the tips ; the tibiae are dark yellow ; 

 their tips and the tarsi are black ; the squamulae and the costal veins are pale yellow ; 

 the stigmata are pale brown ; the other veins are brown. 



Abundant near Lancaster, in the middle of October. 



Aphis — ? 



The winged viviparous female. While a pupa the body is nearly elliptical, grass- 

 green, sometimes varied with red: the antennae are dull yellow and hardly more than 

 half the length of the body : the eyes are dark brown : the rostrum is dull yellow, 

 with a brown tip : the tubes are about one-twelfth of the length of the body : the legs 

 are pale yellow ; the tarsi and the tips of the tibiae are brown. When the wings are 

 unfolded the body is small, black and shining: the abdomen is dark green, with a 

 row of black spots on each side ; these spots are sometimes confluent, and spread over 

 the whole back, whose disk is always black : the antennae are shorter than the body : 

 the rostrum is dull green, with a black tip : the tubes are black and as long as one- 

 eighth of the body : the legs are dull yellow ; the thighs except the base, the tarsi and 

 the tips of the tibiae are black : the wings are colourless and very much longer than 

 the body ; the squamulae are pale green or pale yellow ; the stigmata are pale brown ; 

 the veins are brown. The legs are sometimes quite black, with the exception of the 

 dull pale yellow base of the fore thighs. Perhaps this is the winged state of Aphis 

 prunina. 



During May.
