46 Mr. F. Walker’s Descriptions of Aphides. 
5th var. The body is brown: the feelers are black, and longer 
than the body: the tip of the abdomen is yellow: the nectaries 
are black, and rather less than one-fourth of the length of the 
body : the legs are black ; the thighs from the base to the middle 
and the shanks except their tips are yellow. 
6th var. The body is dark green: the feelers are dull green at 
the base and as long as the body: the mouth is green at the 
base: the legs are pale green ; the feet and the tips of the in 
and of the shanks are black. 
Sometimes green and yellow are variously mixed together in 
the body ; sometimes it is dull yellow, or pale red, or red with 
the disc of the abdomen nearly black, and with the thighs black 
from the middle to the tips, or red with the head green, or green 
mottled with red, or nearly black, or with a slight metallic tinge. 
The young ones in the body are sometimes twenty or so in num- 
ber and of various size: the tubercles which support the feelers 
are short; the second joint of the feelers is much shorter and 
narrower than the first ; the third is much more slender ten the 
second. 
The viviparous winged female. It is brown: the lobes of the 
chest and a row of spots on each side of the abdomen are black: 
the feelers are black, and a little longer than the body : the mouth 
is yellow ; its tip and the eyes are black : the nectaries are black, 
and as long as one-fifth of the body: the tip of the abdomen is 
yellow: the legs are long and yellow ; the thighs, excepting the 
base, the feet, and the tips of the shanks, are black: the wings © 
are colourless ; the wing-ribs and the veins are pale yellow ; the 
wing-brands are pale brown. 
Ist var. The body is reddish brown: the fore-border and the 
hind-border of the fore-chest are paler : the abdomen is dull yel- 
lowish green with a row of very small black dots on each side: 
the feelers and the eyes are black, and the former are a little 
longer than the body: the mouth is dull green with a black tip: 
the nectaries are a little more than one-fourth of the length of 
the body : the wing-brands and the veins are brown. 
The thighs are of a deeper black and the shanks of a brighter 
yellow than those of the wingless female. The red colour of this 
species becomes much brighter when it is preserved in Canada 
balsam. The colour of the pupa is more often red than that of 
the wingless female, and the nectaries of the latter are somewhat 
shorter than those of the former. 
2nd var. The body is green with a slight bluish tint : the dise 
of the head and that of the chest and of the breast are red: the 
mouth is dull green witha black tip: the nectaries are as long as 
one-fourth of the body: the thighs are green towards the base. 
The structure of the wings does not serve to distinguish this from 
the preceding species.
