Alate viviparous female.—Body long oval, with a very slight bloom on the 
undersurface of the thorax. 
The colour of the head and thorax appears dusky ochraceous yellow; abdomen 
a darker green than the apterous female; antennae, legs and cornicles much blacker. 
The pattern on the abdomen consists of three large circular spots on the carina 
of the pre-cornicular portion. One small spot on the first abdominal and another 
faint one just outside the cornicles : a row of large transversely flattened spots in the 
lateral grooves. At least two round spots in front and in line with the cornicles ; 
about two transverse stripes on the mid-dorsum of the first two abdominal segments. 
There is no spot around the bases of the cornicles or on the hinder segments which 
are said to be present in true Macrosiphum rosae. 
Head dusky or black, concolorous, with small frontal tubercles; front rather 
shallow, not deeply channelled as in other species. 
Eyes red ; with stemmata and the usual three ocelli. 
Antennae wholly black, longer than body. 
Length proportions exactly the same as in apterous females.

Sensoria (secondary) on article III from 14 to 16, placed ven ally, almost in one 
line ; all of them circular and having a double contour. 
"The prothorax bears a broad dusky band on its anterior margin and a distinct 
lateral tubercle on either side; concolorous with mesothorax. 
Mesothorax ochraceous yellow in colour ; on its dorsum four black muscle-bosses 
and prominent stigmal spots on lateral sides; meso-sternal bosses also occupy a small 
area on the ventral side, while on their sides, a little laterally placed, are two con- 
spicuous but small dots. 
The metathorax has a transverse band in front of which is to be seen another 
semilunar mark. 
The wings are large with normal venation; occasionally the second furcal is want- : 
ing. 
Stigmal flattening dark brown ; a camera lucida drawing shows the arrrangement 
of the veins. 
Cornicles quite black, similar to the apterous Fenzale, only smaller in size. 
Cauda long, with a Shah constriction above the broad basal third part; it is 
about half the length of the cornicles. 
The legs are much blacker, specially the distal femora and tarsi, which are of 
the same colour as the cornicles ; tibiae dusky, coxae of body colour.
