Mr. F. Walker’s Descriptions of Aphides. - Ba 
The oviparous wingless female. Found with the preceding, which 
it much resembles, but the hind-shanks are black, wide, and 
slightly curved. The eggs are laid in the beginning of October, 
and occur in abundance on the spikes of the furze. 
The winged male. While a pupa it resembles the wingless 
Aphis: the feelers are rather more than half the length of the 
body : the nectaries are as long as one-tenth of the body: the 
legs are dull pale green; the feet and the tips of the thighs and 
of the shanks are black: the rudimentary wings are dull green. 
When the wings are unfolded it is black, and very small: the 
feelers are nearly as long as the body; the fourth joint is very 
nearly as long as the third ; the fifth is as long as the fourth ; the 
sixth is about half the length of the fifth ; the seventh is longer 
than the fifth : the mouth is yellow with a black tip: the shanks 
except their tips, and the four anterior thighs at the base are 
yellow: the wing-ribs are yellow; the brands and the veins are 
brown.

‘The viviparous wingless female. In August 1847 I found this 
species im great profusion under the leaves of the comfrey 
(Symphytum officinale) near Tottenham, but could see it nowhere 
else, notwithstanding the common occurrence of the plant. The 
grub of Agromyza?, of an orange colour and above one line in 
length, frequently devours it; an Aphidius and an Allotria are 
also among its enemies. It is a small species, oval, plump, 
bright yellow, with dark green nectaries ; the head is often dark 
green, and sometimes this colour extends partly or wholly over 
the body, and is more or less mingled with yellow. It discolours 
the leaves of the comfrey, which are nevertheless adorned by its 
bright and many-coloured clusters. The forehead is convex in 
the middle, and has a slight tubercle on each side at the base of 
the feelers: the mouth reaches the middle hips: the feelers are 
setaceous, and shorter than the body ; the fourth joint is shorter 
than the third; the fifth is a little shorter than the fourth; the 
sixth isa little more than half the length of the fifth ; the seventh 
is more than twice the length of the sixth: the fore-chest has a 
suture across the middle ; its sides are slightly convex : the nec- 
taries vary in length from one-sixth to one-twelfth of the length 
of the body, and in. some cases where they are shortest, the legs 
also are very short, and the feelers are much less than half the 
length of the body: the fore-legs are but little shorter than the 
hind-legs ; the shanks are straight. 
Ist var. The body is dark green, with a white bloom, and 
mottled with paler green : the feelers are yellow with brown tips,
