rings upon the antennae, which are always broad in our insect and 
are one of the first marks which the eye notices, but are repre¬ 
sented as quite narrow and inconspicuous in the European. This 
is rommon upon hickory leaves; but the insects of this genus do 
not crowd themselves together and remain stationary like other 
plant lice, 
168 . Dotted-winged gay-louse, Callipterus punctatellus, Fitch. 
A plant-louse like the preceding, but with black feet and a 
black dot on the base and another on the apex of each of the 
veins of its fore wings. Length 0.12. See Transactions, 1854, 
p. 869. 
169. Spotted-winged gay-louse, Callipterus maculellus , Fitch. 
A plant-louse like the preceding, but with the veins of the 
fore wings margined in part with smoky and a black band near 
the tips of the hind thighs, the black rings upon the antennae nar¬ 
row. Length 0.12. See Transactions, 1854, p. 870. 
170. Smoky-winged gay-louse, Callipterusfumipennellus , Fitca. 
A plant-louse similar to the preceding, of a dull yellow color 
ivitli blackish leet and the wings smoky with coarse brown veins. 
Length 0.13. See Transactions, 1854, p. 870. 
171. Black-margined gay-louse, Callipterus marginellus, Fitch. 
A plant-louse similar to No. 166 but with a black stripe along 
each side of the head and thorax, and on the outer margin of both 
pairs of wings. Length 0.15. See Transactions, 1854, p. 870. 
172. Freckled leak-hopper, Jassus irroratus, Say. (Homoptcra. Tettwo- 
niidse.) ° 
A cylindrio oblong white leaf-hopper closely inscribed and reti¬ 
culated with slender black lines and small dots which form irre. 
gular spots along the margins of the wing covers, its legs white 
dotted with black. Length 0.25. Whilst several of its kindred 
draw their nourishment from grass and growing crops of grain this 
very common species is usually found upon the leaves of a varietv of 
bushes, oftener upon those of the walnut and hickory than any 
other kind, according to my observations.
