:arsi, joints of the legs, and the posterior two-thirds of the femora 
black, rest of the legs pale-greenish. Wings pale neutral tint, lighter 
it the base.” 
He does not state on what part of the plant it feeds; according to 
Koch, it is found on the flower stalks and even in the flower itself. 
Aphis nerii? Fonscol. 
Found on Oleander and other closely allied house plants. 
Winged individuals. —Antennae varying somewhat in length but 
usually not extending quite to the tip of the abdomen; there is ap¬ 
parently a slight tubercle at the base indicating an approximation to 
Siphonophora; third joint but slightly longer than the fourth ; fifth 
ibout two-thirds the length of the fourth and twice the length 
of the sixth ; seventh longest, about equal to the third and sixth 
inited ; an occasional, little spine-like hair can be seen along the sides 
with a strong power. The second fork of the discoidal vein is nearer 
w the apex than to the third vein ; costal and sub-costal veins nearly 
oaralell. Tail short, rather broad, somewhat clavate and about one- 
third the length of the honey-tubes. 
General color a pretty and bright saffron yellow ; head smoky yel 
low; eyes black or dark brown ; neck or prothorax yellow, thorax 
Dr thoracic lobes dark brown; abdomen bright yellow ; honey-tubes 
black or dark, the base usually surrounded by a paler or whitish ring; 
i small dark spot on the abdomen behind the honey-tubes, and occa¬ 
sionally the dorsal portion sparsley sprinkled with black dots. Legs 
yellow, tips of the femora, the knees, and tarsi dark. Anterior wings 
somewhat smoky, veins somewhat slender and dark ; beak pale yel¬ 
lowish, tipped with black. Antennae dark or blackish ; tail dark 
brown. 
Length of body .07 inch; to the tip of the wings .12 inch. 
Wingless individuals. —Yellow throughout except as follows : front 
of the head dusky; antennae, legs, honey-tubes and tail dark, as in the 
winged ; the beak dusky at the tip. Antennae not reaching beyond 
the base of the honey-tubes. The beak reaches to the base of the 
second pair of legs, in both winged and apterous. Body broadly ovate. 
Length of body .08 to .10 inch. 
It is quite probable that the only winged specimen examined is a 
male, which will account for its small size. Although the lice were 
numerous, only one winged one was obtained when there was an op¬ 
portunity for examining them. 
Found on the tender branches and petioles of the oleander ( Nerium 
oleander) and other closely allied plants. 
I think it quite probable that this is identical with Aphis nerii , 
Fonscol, but as I have no description of that species, I have placed a 
(mark of doubt after the scientific name.
