The injury u nlniost entirely due to tho cpg-laying habiti of the insect. The eggs are deposited on the upper side of the sninlh-r i)runche8 and also in the case of young trees on the triiiiirc laying her eggs tho , with her sword-likc ovipositor, makes a small, more or less crescent- shaped cut through the bark and then places the eggs in thia. As soon as this is done, she makes another similar slit close to and juat opposite the ^'rst, and deposits eggs in it too. The wood hineath these two slits does not i .-al. but tauscs an ugly scar which continues to enlarge for several years. As the whole upper surface of the branches and also, in exceptional cases, the trunks of young may be almost covered with these slits and scars, it naturally follows that such trees are weakened, dwarfed and more likely to succumb to severe winters or disease than uninjured trcs. Some forest trees and shrubs are also BuffaiO Tree-hopper aduUs and egg scars on branch, natural size. (Original.) The adult Tree-hopper is about one-third of an inch long, moderately stout, triangular in front with the two upper angles projecting somewhat and suggesting the nsine "Buffalo ; Tlie upper surface of the body slopes gradually back from the front to rear, so that from a side view also the insect has a tri- angular appearance. The general color is pale green. Life History. The winter is in the egg stage in the slits of the bark. The eggs hatch about the time the leaf buds burst. The young nyninhs after a very short time go to the ground, where they feed on almost anv kind of succp- lent weeds, sucking the juices out of these. In July they begin
