=Pentatoma ligata=, or the Bound Tree-bug, is also grassy-green, but more widely bordered all round, except the head, with pale red, and has a pale red spot on the middle of its back and on the apex of its scutel; antennæ green. =Arma modesta=, or the Modest Tree-bug, is tawny, yellowish-gray, thickly dotted with brown punctures; the wing-covers are red at the apex of their leathery portion, and have a brown spot at the tip of the hyaline portion; the under side is whitish, with a row of black dots along the middle, and another on each side. =Thelia univittata=, (_Harris_), or the Single-striped Treehopper, is chestnut-brown, shaped like a beech-nut, with a perpendicular protuberance on the fore part of its back, higher than wide. It is tawny white in front, a white stripe along the back to the tip; length 0.37 inch; July and August. =Ceresa bubalus=, or Buffalo Treehopper, is of a light grass-green, freckled with whitish dots; with a sharp short point on each side, projecting like horns. =Ceresa taurina=, is like the preceding, but the space between the horns is concave. =Acutalis dorsalis=, is a small, triangular, shining Treehopper, with a smooth round back; it is greenish-white, with a large black spot, from the anterior corners of which a line runs off to each eye. Plentiful about the last of July, a few remaining until October. =Erythroneura vitis=, (_Harris_), or the Vine-leaf hopper, is pale yellow, with two broad blood-red bands, and a third dusky one on the apex. Swarms of these small insects occur in August, and often bleed the foliage so as to injure it seriously. =Erythroneura tricincta=, or the Three-banded Leaf-hopper, is like the preceding species, but the bands are narrower. =Erythroneura vitifex=, or the Vine-destroying Leaf-hopper, is yellowish-white; the wing-covers have oblique confluent, blood-red bands, and a short, oblique, black line on the middle of their outer margin. The thorax commonly has three red stripes, the middle one forked anteriorly and confluent, with two red stripes on the crown of the head. When the wing-covers are closed, they look red, with a cream-colored spot, shaped like a heart placed anteriorly, and on the middle, a large diamond-shaped spot, with a small red spot in its centre. These insects are sometimes seen in such numbers upon the grape vines in September, that, when the leaves are disturbed, they fly out and resemble a shower of snowflakes. The young resemble their parents, but are destitute of wings. A REMEDY is much needed. =Erythroneura vulnerata=, (_Fitch_), or the Wounded Treehopper, is tawny yellowish, sometimes tinged with red; the wing-covers have white spots and veins, and on the middle of the outer margin an oblique black streak, between two creamy white spots; the hind one smaller, and an oblique blood-red line at its end; tips smoky-blackish; length 0.12 inch; September.
