i50 ANNUAL REPORT OF NEW-YORE 



HICKORY. LEAVES 



173. Four-striped leaf-hopper, Tettigonia qimdrivittata, Say. (Homop- 

 tera. Tettigoniidse.) 



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, Uroxiphus CarycR, Fitch. (Homoptera. Membra- 

 cidae.) 



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. OxE-coLORED TREE-HOPPER, T slamoTia unicoloT, Fitch. (Homoptera. 

 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.
