The larva* seem partly to live in this gummy substance and partly in the sapwood of the tree. Sometimes three or four are found on the same tree, occasionally girdling and destroyin" it, but always inducing more or less of a diseased condition, and impairing its vicrour. Altogether it is a very objectionable and destructive insect. f, i UEMEDIES. It is usual on the appearance of these gummy masses to cut them away, trace out the larva" and destroy it. By watchfulness in this way its deprc^dations may be stopped. It lias been sugg<'sted that banking up the trees with (sarfli would prevent the insects from depositing their eggs, and the method is very strongly reconnnended by those who have tried it. As a rule those who look after their peach trees closely liave not much trouble with the borer. It is easily discovered by this gummy exudation, and can be easily taken out and destroyed if it is looktnl after at the proper season.

The green grape vine Sphinx (Choerocampn pampinatrix,) is one of the commonest insects which devour the foliage of the grape, and when abundant, it almost entirely strips the vines of their foliage. It is a large green caterpillar (See figure 94), striped at the \_Mr. W. Saunders.]. Please note that these images are extracted from scanned page images that may ha
