Watering the ground with lime-water, about the roots of the trees, during winter, applying spirits of tar, or ammoniacal gas-water, will do much to lessen their numbers. Melolontha (Anisoplia) horticola of Fabr., Phyliopertha horticola of Kirby and Stephens, fig. 181, is a leaf-eating beetle, and is parti- cularly injurious to the apple, although it attacks other fruit trees also. Its body, head, and thorax are dark green; its anten- nae reddish, with a strong termi- nal club; the wing - cases red- dish brown, somewhat shining, and not extending to the ex- treme point of the body. They attack the foliage of trees, which they perforate with holes both large and numerous. They in- habit the trees during summer, pair in early autumn, when the female drops to the ground, and deposits her eggs two or three inches under the surface. The larvae, when hatched, continue in the ground, feeding on the roots of plants, until transformed in spring into beetles, when they horticola'and *&? ^nd the trees in search larva. of food. The same means may be taken for their destruction as recommended for the last. Aphis pyri mali; the apple aphis or plant- louse.—This extensive genus, generally known as the green-fiy, is sufficiently well known. It has been asserted that almost every genus of plants has a species of the family almost peculiar to itself. For mode of destruction, &c, vide Peach Tree. It is singular that Kollar, in his " Treatise on Insects injurious to Gardens," &c, should not mention the Aphis lanigera, an in- sect, according to Downing, common in France and Germany, and which he asserts was trans- ported from those countries to America.
