ANNUAL REPORT OF NEW-YORK 
BUTTERNUT. LEAVES 
cording to the description is marked precisely like the arcuata of 
Say, but the dimensions assigned it are a fourth larger than those 
of that species. 
192. Obtuse Clastoptera, Clastoptera obtusa , Say. (Ilomoptera. Ccr- 
copidae.) 
A short thick almost circular leaf-hopper of a gray color with 
fine transverse wrinkles and three brown bands anteriorly, its 
wing covers clouded with tawny brown with streaks of white and 
a coal black spot near their tips. Length 0.22. 
From the middle of July till the end of the season this insect 
may frequently be met with on quite a number of different trees 
and shrubs. Although the species of this American genus very 
much resemble those of the genus Penthimia they certainly per¬ 
tain to the family Cercopidse and not to that of Tettigonikke in 
which they are placed by Mr. Walker. 
103 . Butternut Tingis, Tingis Jugianats , new species. (Ilemiptera. 
Tingidse.) 
Puncturing the leaves and sucking their juices, a small singular 
bug resembling a flake of white froth, its whole upper surface 
composed of a net-work of small cells, an inflated egg-shaped pro¬ 
tuberance like a little bladder on the top of the thorax and head, 
the sides of the thorax and of the wi ng covers except at their tips 
ciliated with minute spines, the wing covers flat and square with 
their corners rounded, a large brown or blackish spot on the 
shoulder and a broad band of the same color on their tips with an 
irregular whitish hyaline spot on the inner hind corner; the body 
beneath small and black, the antenna and legs honey-yellow. 
Length 0.14. 
This insect becomes common on the leaves of the butternut in 
May and continues through the summer and autumn. It may 
sometimes be met with also on birch, on willows, and other trees. 
It corresponds with the arcuata of Say (Heteropterous Hcmiptcra, 
p. 27) in every respect, except that the outer margin of the wing 
covers is rectilinear and not arcuated or concavely excavated, and 
their veins are not ciliated with minute erect spines. I have 
never met with the arcuata in the state of New-York, but have 
gathered it from bushes in the outskirts of the city of Chicago.
