88 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
when fully grown; darkest above, and with indistinet blackish spots upon the sides. 
The head is white, with a small black dot upon each side. Specimens were taken 
upon the Jeaves July 4. Went into the ground about the 20th of July. The cocoon 
is formed near the surface of the ground of a little earth or sand drawn together- 
Four specimens came forth about August 22, all seemingly very small for so large 
larvee. (Norton in Packard’s Guide to the Study of Insects. ) 
5. THE TWO-MARKED TREE-HOPPER. 
Euchenopa binotata Say. 
Order HEMIPTERA; family MEMBRACID®. 
Puncturing the leaves and extracting their juices from July till the end of the 
season, a small rusty brown or black tree-hopper, with two bright pale yellow spots 
upon its back, which part is prolonged forward and upward into a compressed horn 
rounded at its tip and giving the insect a resemblance to a little bird with an out- 
stretched neck, and the four forward shanks broad, thin, and leaf-like. Length, 0.25 
to 0.30 inch. (Fitch.) 
6. THE BUTTERNUT TREE-HOPPER. 
Ophiderma mera Say. 
Belonging to the same family as the preceding, a greenish-gray tree-hopper, shaped 
like a half cone, with its apex bright chestnut-red, and behind its middle a black 
band which is sometimes interrupted on the summit of the back, and with a blackish 
spot on the tips of the hyaline fore wings. Length 0.36 inch. (Fitch.) 
7. THE OBTUSE CLASTOPTERA. 
Clastoptera obtusa Say. 
A short thick almost circular leaf-hopper of a gray color, with fine transverse 
Wrinkles and three brown bands anteriorly, its fore wings clouded with tawny brown 
with streaks of white and a coal-black spot near their tips. Length 0.22 inch, 
(Fitch. ) 
8, THE BUTTERNUT TINGIS. 
Tingis juglandis Fitch. 
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 protuberance like a little bladder on the top of the thorax and 
head, the sides of the thorax and of the fore wings, except at their tips, minutely 
spinulose; the fore wings 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 antennz and legs honey-yellow. Length 0.14 inch. (Fitch.) 
Fitch remarks that 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 the birch, willows, and other trees. 
We have found it in abundance on the butternut at Brunswick, Me., 
late in August in all stages of growth. 
9, THE VIRGINIA TIGER-MOTH. 
Spilosoma virginica (Fabricius). 
Order LEPIDOPTERA; family BOMBYCID®. 
Occasionally devouring the leaves of the butternut, a very hairy, deep yellow cater- 
pillar, with a black head and body, the latter mottled with black; changing to a. 
thick chrysalis within a cocoon, where it remains until the following June, when it 
appears as a white moth. 
This omnivorous caterpillar, commonly called “the yellow bear,” is 
known to feed on the butternut, grape vine, current, gooseberry, grasses,
