The prothorax bears a transverse band on its anterior half, concolorous with the 
head. 
Mesothorax yellowish green with shining black muscle elevations as usual over the 
dorsum, occupying about the half of its middle surface. Lateral black spots present. 
Metathorax with a black stripe and another triangular elevation in front, nar- 
rower than the mesothorax. 
Wings longer than usual, somewhat narrowed towards the tip ; about three times 
as long as broad. Stigmal flattening dusky, the rest, including insertions, yellow- 
ish. All the veins are clouded with a blackish pigment; membrane also somewhat 
smoky. There is a prominent bend at the first forking of the cubitus. 
Abnormalities are numerous; sometimes the first and second furcal are very Jose 
to each other, in others the al is forked. One very strange freak is shown in 
the camera drawing of two pairs of wings; all the veins are branching even in the 
hind-wing. 
Cornicles much like that of the apterous female, but more clearly incrassate to- 
wards their inner side and darker in colour. They narrow into a sort of neck just 
below the flanged tip ; scaly. 
Cauda, anal and genital plate very similar in both forms. 
The capitate hairs are more marked on the posterior extremity on account of the 
small size of the segments. 
Lateral tubercles not apparent. 
Legs black at the coxae, distal femora and tarsi; tibiae brown. A dark band 
between hind coxae, narrow in the middle. 
Rostrum brown-black, tipped and sharp-pointed ; it can be readily withdrawn 
from the leaf; it reaches up to the second coxae.

Natural history.—This pretty species is one of the smallest to be found in Lahore 
and has a curious habit of sitting in notches on the margins of leaves. It also crowds 
among very young and tender leaves and only when abundant attacks the lower veins 
and flower stalks. In the latter situation it is frequently to be noticed feeding in 
company with two other aphid pests of Chrysanthemums, 7.c., Aphis malvoides, 
sp. nov., and Macrosiphum sanborni (Gill.), about late December in the Gol Bag or 
gardens outside Bhati Gate. 
Its small size and entirely cryptic colour, which quite matches with that of the 
leaves of its host, necessitated a careful examination to make sure of its presence.
