I57 The remedies recommended for the apple-tree aphis (No. 57) will be serviceable for this insect also. No. 80.—Grasshoppers, or Locusts. In addition to the insects already treated of, several species of grasshoppers, or, more correctly, locusts, attack the leaves of the pear, and, when abundant, will often entirely strip young trees of their foliage. In Fig. 164 we have a repre- sentation of the red-legged locust, Oaloptenus femur-rubrum (De Geer), one of our commonest species, which is abundant everywhere, from Maine to Minnesota, throughout the greater portion of Canada, and from Pennsylvania to Kansas. In Fig. 165 is shown the noted Rocky Mountain locust, Calop- FiG. 164. \ Tig. tenus spretus Thomas, which has proved so terribly destructive in the West and Northwest. Although much resembling the red-legged locust in size and general appearance, the wings are longer, and there are -other points of difference which enable the entomologist readily to separate the species. These, however, need not be enumerated here. In Fig. 166 the females of the Rocky Mountain locust are depicted at a, a, a, in the act of depositing their eggs. These eggs are laiH in the ground in masses, in which the eggs are carefully arranged, and the whole coated wdth a gummy covering. In the lower part of the figure one of the egg-masses is shown with one end open, others in position at d and e, and the eggs sepaVated at c; /shows where an egg-mass has been deposited and the aperture closed. In Fig. 167 another common species is represented,—at a in the immature or larval state, at 6 in the mature or perfect condition. This insect is known under the name of the green-.
