Winged female. —Green; the antennae, eyes and honey-tubes blaek. 
Antennae as long or rather longer than the body, the seventh joint 
scarcely as long as the third, but this relative length does not appear 
to be uniform; third joint slightly pustulate, with a few hairs reg¬ 
ularly placed; very similar to the antennae of S. rudbeckiae; first and 
second joints pale greenish yellow, rest dusky. 
The eyes black with the usual posterior tubercle. Beak moderately 
long, pale except at the extreme tip which is black. Honey-tubes 
very Jong, cylindrical and stout, slightly thickest at the base; ex¬ 
tending beyond the tip of the abdomen, and nearly equal one-third the 
length of the body; deep black throughout. Tail distinct, rather 
slender, narrow at the base, slightly enlarged in the middle, curved 
upward and pointed at the apex. Legs long and slender, black except 
the basal half of the thighs which is transparent green. The head 
and thorax are a deeper green than the abdomen, which has a yellow¬ 
ish tint. 
The young are pale greenish yellow; the full grown wingless females 
a light pea-green, with sometimes a deeper-green area in the middle 
part of the abdomen above. The tail, in the apterous individuals, is 
slender and ensiform; and about one third the length of the honey-tubes. 
Length of winged individual .08 inch, to tip of the abdomen; .13 
inch, to tips of the wings. 
Siphonophora coreopsidis. Thos. Aphis of the Spanish Needle. 
Found by Mr. Th. Pergande at St. Louis, Mo., in October, on 
.the heads and flower stalks of Spanish needles ( Coreopsis aristosa). 
I am not absolutely positive as~to the species of plant, as only a little 
fragment was sent of the head, but am satisfied that it was a species 
of Coreopsis. I ascertained nothing further in reference to the habits 
of the species. 
Winged individuals —(Fig. 12.) An ten me about two-thirds the length 
of the body, joints propor¬ 
tioned as usual. Honey-

color of the abdomen. Wings present a slightly smoky appearance;
