BRITISH APHIDES. 
Winged viviparous female. 
Indies. Millimetres. 
Expanse of wings 0*360 9*14 
Size of body 0*110x0-045 2*74xl-13. 
Length of antennse 0*180 4*56. 
„ cornicles 0*050 1*27. 
Large, bright green, shining. Pro-, meso-, and meta- 
thorax shining black. Abdomen wholly shining green, 
without any markings or lateral spots as in S. rosce. 
Eyes red. Antennse and legs longer than in S. rosce. 
Antennae brown, with the exception of the third joint, 
which is ochreous. Legs hirsute, ochreous. Tarsi 
black. Cornicles much curved as in the apterous 
form. Cauda yellow. Wings ample, iridescent ; stigma 
smoky ; veins greenish brown. 
This insect is not unlike Sipkonophora rosce in colour, 
but it much differs in its proportion and abdominal 
markings. Koch found it feeding on Euphorbia 
cyparissia. The only specimens I have seen were 
feeding on Scabiosa succisa and Bubus fruticosa in 
July. 
This diversity of food ought to cause no surprise, 
for observation shows the almost omnivorous habits of 
several species of Aphis. Thus Aphis rumicis feeds on 
plants of totally different natural orders, such as the 
bean, the thistle, the furze, the euonymus, &c. 
Although this Aphis has not been recorded before as 
British, I do not doubt, from Koch’s description, that it 
is the insect he thus names.
