HICKORY. LEAVES 
173 . Four-striped leaf-hopper, Teltigonia quadrivittata, Say. (Ilomop- 
tera. Tettigoniidie.) 
A flattened oblong leaf-hopper of a light yellow color, varied 
on the thorax with orange, red or dusky, its wing covers olive 
green each with two bright red or orange stripes, the tips mar¬ 
gined with black. Length 0.35. This pretty insect, like the 
preceding, occurs upon a variety of other bushes in addition to 
the walnut. 
174. Walnut sword-tail, Vroociphus Cuvyaz, Fitch, (Iloinoptera. Meiabra- 
cidse.) 
A dull brown tree-hopper with the terminal portion of its 
wing covers obscure ash-gray, its abdomen and a ring on its shanks 
pale yellowish, and its breast mealy white. Length 0.30, the 
female 0.37. This is a somewhat common insect, which I have 
found only upon the walnut. 
175. One-colored tree-hopper, T damona unicolor, Fitch. (Ilomoptera. 
Membracidae.) 
A tree-hopper of a uniform dull ochre yellow color and some¬ 
what like a beechnut in shape and size, with a prominent hump 
jutting up on the middle of its back, highest anteriorly and de¬ 
scending with a slight curve to its hind angle which is very ob¬ 
tusely rounded and but little prominent, its anterior angle also 
rounded and with only a slight concavity below it at the forward 
end of the hump, whilst at its posterior base is a strong one, the 
whole surface with close coarse punctures and showing a few 
elevated longitudinal lines low down on each side and towards 
the tip ; the upper edge of the hump black and also the tip of the 
abdomen on its under side ; wing covers glassy with a black spot 
on their base and tip and their veins margined with slender black 
lines. Length 0.45, height 0.25. A variety ( irrorata ) occurs, 
of a paler grayish yellow color freckled with numerous pale green 
dots in the dried specimen. This is a rare species which I have 
only met with in a few instances, always finding it on walnut 
bushes.
