342 Mr. F. Walker^s Descriptions of Aphides. 
men is traversed by bands like those of the wingless female : 
the feelers are as long as or a little longer than the body ; the 
tips of their joints, and sometimes the whole of them excepting 
the base, are black : the eyes, the tip of the mouth, the tips of the 
nectaries, the feet, and the hind-thighs from the middle to the 
base, and sometimes the whole of them, are black ; there is also 
a black ring rouod each middle thigh : the wings are colourless; 
the wing-ribs and the rib-veins are pale yellow; the wing- brands 
are colourless ; the first branch-vein is strongly marked ; the 
fourth is more or less wanting ; the tips of the veins are slightly 
shaded. 
The body is rather short and broad ; the middle of the front 
of the head is prominent and armed with bristles : the first joint 
of the feelers has a black spot on its inner side ; the fourth joint 
is very much shorter than the third ; the fifth is as long as the 
fourth ; the sixth is full half the length of the fifth ; the seventh 
is shorter than the sixth : the sides of the fore-chest are convex 
and slightly notched : the legs are moderately long ; the fore-legs 
are much shorter than the hind-legs : the main wing-vein is 
slightly curved inwards and outwards, and is somewhat clouded 
on the inner side at its tip, but does not form a distinct brand ; 
the first branch -vein is nearly perpendicular ; the second and the 
third are strongly marked towards the base ; the latter is very 
distinct till close to its source, and sends forth its forks at one- 
third and at two-thirds of its length ; these forks are very slen- 
dei’, and, as in other species of this group, they are much di- 
verging from each other. 
1st variety. The abdomen is not traversed by bands. 
2nd variety. The head and the chest are almost black. 
3rd variety. The sutures of the chest are yellow. 
4th variety. The head is black : the disc of the chest is brown. 
5th variety. The whole of the hind-thighs is black. 
6th variety. The tips of the middle thighs are brown or black. 
The main wing does not form an angle but a curve beneath 
the place of the brand ; the third vein is sometimes forked after 
one-third, and again after two- thirds of its length : all the veins 
have the same thickness when the wings are just unfolded. 
The oviparous wingless female. This occurs in October and con- 
tinues till the end of November: it is pale j^ellow varied with 
green : the feelers are black about the middle, and more than 
half the length of the body : the tips of the feet are also black : 
the tip of the abdomen is lengthened : the hind -shanks are dilated. 
1 st variety. Pale yellow varied with bright yellow. 
2nd variety. Pale yellow varied with orange. 
3rd variety. Pale greenish yellow, with a lively irregular green 
stripe on each side.
