it is afterwards bright yellow : the sides of the head and of the 
chest are brown, which colour adds to the linear appearance of 
the body by forming two continuous lines with the fore-borders 
of the upper wings when they are at rest : the forehead is convex 
and somewhat notched : the feelers have alternate black and yel- 
low rings, and are nearly as long as the body ; the fourth joint 
is rather more than half the length of the third ; the fifth is a 
little shorter than the fourth ; the sixth is shorter than the fifth ; 
the seventh is much shorter than the sixth : the eyes are bright 
red : the tip of the mouth and the hind-thighs, except the base, 
are black : the fore-chest is large, a little narrower in front ; its 
sides are slightly indented : the wings are colourless and much 
longer than the body; the wing-brands are dark brown; the 
veins are brown, and their tips are much shaded; the second 
branch-vein is curved. The pupa is pale yellow and elliptical ; 
the tips of the joints of the feelers are black ; the tip of the 
mouth and the tips of the feet are brown : the young ones within 
its body are very small. 
1st variety. Pupa. White and shining : there is a black spot 
on each side of the chest, and on each side of the abdomen there 
is one distinct row and a slight indication of a second and outer 
row of black spots : the tips of the joints of the feelers, the tip of 
the mouth, and the feet are black. 
2nd variety. Body varied with lemon colour or pale yellow. 
3rd variety. Body yellow with four rows of black dots along 
the back. 
4th variety. Body bright orange with a row of black spots on 
each side. 
It is the prey of an Aphidius, and I believe that Myina flava 
is also one of its parasites. It has sometimes two dozen young 
ones within its body, and about twelve of these are of large size, 
the rest are smaller. 
Length of the body 1^ line ; of the wings lines. 
There is a small tubercle on the inner side of the base of each 
feeler : the main vein of the wing is very strong ; the space be- 
tween it and the fore-border is yellow along its whole length, but 
the brand is sometimes colourless with the exception of its border, 
which is shaded ; the first branch-vein is nearly straight ; the 
second is curved ; the third is slightly curved and is distinct till 
very near its source ; it is forked before one-third, and is forked 
again before two- thirds of its length : the inclination of the main 
vein both inwards and outwards is very slight : the legs are of 
moderate length, and the fore-legs are but very little shorter 
than the hind-legs. 
The oviparous wingless female. This appears in September, and 
continues beneath the lime-leaves till near the end of October :
