Arms. WINGED FEMALE DESCRIBED. 
And the older ones after a time dieing and disappearing, before 
these inseots began to attract public notice they had all been 
changed to this orange color, their hue inclining more to red in 
some and to yellow in others. It is truly curious that this green 
insect, thus, on coming to feed on the juices which grow the flow¬ 
ers, begins to produce young of a gay yellow color similar to that 
of the flowers. 
We distinguish this plant-louse from other species by its oc¬ 
curring oh grain, and having the body of a bright grass green 
color when it is found on the leaves, and reddish yellow or orange 
when on the heads, the outer ends of its thighs being black and 
also its feet, the ends of its shanks, its antennas and honey-tubes. 
The young larvas of some of our plant bugs belonging to the 
genus Phytocoris, are met with on grain and are of the same size 
and the same bright green color as this aphis, but they are dis¬ 
tinguished from it most readily by their motions, the young bugs 
always walking about with a brisk animated pace, whilst the 
aphis is sloggish and lazy in its movements. 
The winged female (Plate i, fig. 5) is 0.10 long, or to the tip of the closed wings 0.20. 
Head transverse, convex in front, rectilinear at base, dull pulo yellow. Eyes jutting out 
from each side of the head, globular, usually of a rusty reddish color. Eyelets or ocelli three, 
appealing like minute glassy dots pluced at the angles of an imaginary triangle, far apart, 
one near the upper edge of each eye and the third one forming a slight projection upon the 
middle of the forehead. Beak appressed to the breast, arising between the base of the fore¬ 
legs and reaching half-way to the middle legs, pale green, its tip black. Antennas long and 
slender, abo^t equalling the body in length, tapering, black, their bases obscure yellowish, 
seven-jointed; basal joint thrice as thick as the third joint, short oylindric, little longer than 
thick, abruptly narrowed at its end; second joint nearly globular and twico as thick as the 
•third joint, which is very long; fourth and fifth joints long; sixth but a third the length of 
the fifth; seventh moro slender, tapering, about as long as the third; articulations of the 
joints except the first two inconspicuous and indicated only by the end of each joint being 
slightly thickened and bluntly rounded; joints clothed with distant inclined hairs which are 
quite short and coarse. Thorax nearly globular; collar much narrower, narrowing forward, 
a little longer than the head, grass green; remainder of the thorax dull pale yellow and 
shining, abovo with a large egg-shaped black or brown spot on each side and between the 
forward ends of these spots a smaller oval one which reaches forward to the collar, these 
three spots being elevated, convex and polished; sides beneath the wing sockets with an 
oval brown spot, paler than those on the back and placed obliquely. Breast dull black 
between the four anterior legs and often dusted with a glaucous powder. Scutel dull pole 
yellow, appearing as an elevated smooth transverse ridge of a semicircular form above tho 
base of the abdomen. Abdomen broad oval, rounded at tip, grass green, with a row of about 
three blackish dots on each side forward of tho base of tho honey tubes. Honey'tubes black, 
as long as to tho tip of the abdomen, slightly thieker towards their bases. Tail very pale 
greenish yellow, straight along its upper and convex on its under side. Legs long and slen¬ 
der, hind pair longest; thighs very palo greenish, towards their middle becoming yellowish 
and beyond this hlack; shanks bearded with fine short hairs, palo dull yellow, their tips 
lack. Feet short and slender, but half as thick as the shanks, obscuroly two-jointed and 
with two small claws at their end. Wings hold together in a steep roof over tho body 
transparent, with slender brown veins, the rib-vein thick and sulphur yellow, as is the stigma
