THE BUFFALO TREE-HOPPER. {Ceresa. bubal us Fabr.) 
A light-green, three-cornered insect, about one-third of 
an inch in length. What appears to be the head, really the 
thorax, is large and broad and terminates abruptly, having 
on either side a short, sharp spine, or thorn, somewhat re- 
sembling the horn of the buffalo, and hence the common 
name of the insect, which is, withal, a good jumper. This 
insect feeds upon a great variety of plants and is quite 
abundant in Colorado. It does its chief injury while depos- 
iting eggs during the months of August and September in 
small limbs of various trees, including the apple. A double 
row of eggs is deposited in a longitudinal slit that the fe- 
male makes in the bark. The growth of the limb spreads 
the slit into an oval scar as shown in the accompanying illus- 
tration.
