Like most male Aphides, the wings are dispropor- 
tionately large, and the tips rounded. Though the 
body is small the head is large, and wider than the 
thorax. The abdomen small, and hardly exceeds the 
length of the head and thorax together. Colour buff, or 
salmon pink. Head, neck-ring, and thoracic lobes 
rich brown. The abdomen has eight or more brown 
dorsal bands, and two corresponding rows of spots on 
the connexivum. Antennse longer than the body and 
brown. The front rather flat, with rather small 
tubercles. Nectaries buff, as also is the tail. Legs 
brown, with the exception of the upper halves of the 
femora. The coxse are large. 
The wings have arched costse, and all the veins are 
brown. The stigma is more imbricated than usual. 
Apterous oviparous female. 
Delicate green. The antennse rather shorter than 
the body ; slightly darker green at the articulations. 
Eyes brown. Legs very pale green, almost colourless. 
The hind tibia much flattened and expanded. The 
ova usually may be seen through the transparent skin, 
and are of large size. At such times, the parts near 
the vulva are dilated into a kind of sac. 
This species is not uncommon on the young shoots 
of the rose, and may be taken at Haslemere from May 
to November. 
Mr. Walker says it migrates to the wheat plant and 
to various grasses. Also that it may be found feeding 
on Polygonum persicaria. In his catalogue of Homop- 
tera in the British Museum he places S, rosarum^ of
