Alate viviparous female. —Head deep black, comparatively large, about as broad 
as long, bearing pitchy black eyes with ill-defined ocular tubercles. On the sides of 
the dorsum are two hairy elevations which mark out a central rectangular area that 
is somewhat depressed. 
The median ocellus is placed rather ventrally, a little above the lower edge of the 
front, that runs like a hood on the sides and in front of the face, forming a white 
mealy border. 
Antennae comparatively short; in living specimens perfectly black. In length 
the proportions are the same as in the apterous female; article III is the longest, 
about equal to the two following taken together, which are of the same length, about 
one and a half times the 6th. 
Sensoria large, without very distinct hair-rims either on the secondary or primary 
ones. Their number on article III is about fifteen, while four or five are present on 
IV. 
The prothorax is clearly marked off and shows a broad band over its anterior 
half, somewhat constricted in the middle as shown in the drawing. The lateral 
tubercles are placed over the posterior angles. 
The mesothorax is shining black, with broad muscle-bosses ; its anterior edge 
projects into a black peg-like process that goes beneath the prothorax into a triangular 
concavity. | 
The metathorax forms a broad convex band, similar in colour to the mesothorax 
and bounded externally by the dark brown insertions of the hind legs. 
Wings.—Anterior pair rather short, well rounded and narrow in width. On dis- 
tended large viviparous females they look much smaller and out of proportion. They 
seem to be seldom used for flight ; when disturbed, the insect trusts to its legs more 
than its wings. In fact it is very rare to catch this Aphid on the wing. They are 
further characterised by being deeply pigmented with black which often shines like 
jet. The disposition of the pigment is shown in the camera drawing. 
The stigma is long, black, lighter towards the centre. There is a big black patch 
along the first oblique vein, occupying largely the space between the first and the 
second oblique vein; the next cell contains a small area near the hind margin. Most 
of the space between the stigmal vein and the cubitus, with its two forks, is pigmented, 
except a small triangular area behind the stigma; near the margin, between two con- 
secutive veins, are noticeable blotches of deeper black, six in number, beginning with 
the one just in front of the stigmal vein. 
The hind wings are hyaline, with two oblique veins; the subcostal along its
