of March. It is green: the disc of the chest and that of the 
breast, the feelers, the tip of the mouth, the tips of the nectaries, 
the knees, the feet, and the tips of the shanks are brown: the | 
feelers are more than half the length of the body; the fourth 
joint is very much shorter than the third; the fifth is a little 
shorter than the fourth; the sixth is shorter than the fifth ; the 
seventh is a little longer than the sixth; and the nectaries are 
about one-sixth of the length of the body : the wings are colour- 
less and about twice the length of the body: the wing-ribs and 
the brands are green, and the veins are pale brown ; the first and 
the second veins diverge much from each other, but the second 
and the third veins are nearly parallel ; the latter has its first fork 
after one-third and its second fork a little before two-thirds of 
its length ; it is more or less obsolete at the base ; the fourth vein 
is much curved, and the angle of the brand whence it springs is 
hardly perceptible. 
Variations of the wing-veins. —Ist var. The lower branch of 
the first fork of the third vein is wanting. 
Length of the body 2 line; of the wings 24 lines.

This species feeds on Rosa centifolia and gallica in gardens, 
and Mr. Hardy has forwarded to me specimens found on Rosa 
spinosissima in October near Newcastle. 
The viviparous wingless female. This little species appears on 
the rose (Rosa centifolia and gallica) in the beginning of March 
or later, and is then dull green, paler beneath, rather flat, and 
very long: the feelers are rather more than one-fourth, and the 
nectaries are about one-seventh of the length of the body: the 
eyes are brown : the legs are short and stout. During its growth 
it acquires a brighter green hue, and then the limbs are almost 
white: the front of the head is very convex in the middle: the 
first joint of the feelers has a slight protuberance on the inner 
side of its tip; the fourth joint is shorter than the third, but 
longer than the fifth ; the sixth is a little shorter than the fifth ; 
the seventh is much longer than the sixth. It much resembles 
A. Capree. 
lst var. Whitish green, with two vivid green stripes along the 
back. 
2nd var. Whitish green, with two bluish green stripes along 
the back. 
The viviparous winged female. Is black : the fore-chest is green, 
having in front a blackish green band which is sometimes broad 
and sometimes narrow: the abdomen is green; each segment is 
traversed by a black band and has a black spot on each side: the
