142 BRITISH APHIDES. 
the head and thorax together. Four or five trans- 
verse dark green dashes on the dorsum. Cornicles 
as in the winged female. Legs disproportionately 
long. Cauda small. Wings remarkably large. Stigma 
grey. From the under side, the valves which support 
the penis can be easily seen. 
Some males are redder than the above. Occasionally 
the wings want the second cubital fork. Also the j 
clavate character of the nectaries is more marked in j 
some specimens than in others. 
The males are not uncommon on the raspberry 
during the month of November. Late also in autumn 
I received specimens from Wanstead taken on the 
bramble Buhiis fruticosus. 
The apterous oviparous female. 
This measures 0“1 10x0*040 inch. Its form is oval 
or sac-like, but drawn out towards the head. Green, 
slightly pubescent. The antennse and legs are rela- 
tively longer in this sex than in the viviparous female, 
a remark which does not usually apply to other 
species. As the eggs approach maturity they appear 
like oval whitish masses under the skin. After 
deposition and exposure to the air they turn lustrous 
black. 
The oviparous female may be taken at the same 
time as the male on the raspberry. Occasionally they 
occur of a ferruginous red colour. 
The curved and clavate form of the cornicles make 
this species approximate to the genus BJiopalosi^Jium. 
Koch shows this departure from the Siphonophora 
type in his figure of the insect, nevertheless he retains 
it in the latter genus. I do the same, as in all other 
respects it best agrees with Siphonophora. 
Passerini omits 8. rubi from the list of Italian 
Aphides possibly from its partial resemblance to 8. 
urticce, a resemblance which Koch notices. The 
British specimens, however, want the black markings
