not to be uncommon in the open air, all tbrougli tbe 
summer feeding on the Calceolaria, Geranium (Koch) 5 
Malva sylvestris, &c. I have also taken it on Mes;pilus 
germanica. It appears now to be a hardy species, for 
it will survive the winter out of doors on the garden 
Chrysanthemum up to December 25th. It is also widely 
spread, and reaches far north, for the figure is taken 
from a winged insect feeding on the Malloiu in May 
on the Cheviot Hills. In this specimen the ocelli were 
of the normal number. In the greenhouse jS. pelar^ 
gonii continues to produce living young throughout 
the whole year. I have never seen the male, but Koch 
notices a flesh-coloured winged variety having a crimson 
abdomen, which might prove to be that sex. 
It is to be noticed that when an Aphis feeds, the 
tip of the rostrum is pressed against the leaf and the 
lancets alone puncture the plant. When the proboscis 
is free, these lancets sometimes protrude considerably 
beyond the point of the sheath, and then these may be 
often seen in rapid vibration. This insect is very like 
Ajphis malvce^ which, however, differs from the present 
species in having no frontal tubercles, and showing 
shorter antennge and nectaries. 
Mr. Walker, I believe, admitted that his A. pallida 
might be identical with A. pelargonii^ as Passerini has 
stated.
