The Olive Tzvig-Borer.—A reddish brown beetle boring into twigs of olive and other orchard trees, and grape canes, at the axils of the leaves. The insect is shown in the engraving, some- what enlarged, as the line on the right shows the natural length of the insect. It is Polycaon eonfertus, and it breeds in decaying logs and stumps and old grape-vines, apparently visiting the fruit trees merely to gratify its appetite. Its work is not fatal to the tree, but unless proper pruning and attention be afterwards given, it may spoil the shape of a young tree. Remove the af- fected branches below the burrow of the beetle, or if it would be difficult to replace a branch, see that the beetle is destroyed and the entrance to the hole stopped up—this to prevent decay and a weak branch following. Spraying with ill-smelling solu- tions may prevent their attack, but the insect has not beeii suf- ficiently abundant to invite serious efifort thus far. Peach Crown-Borer.—A grub boring into peach trees just below the ground surface, its presence being shown by copious gumming. The insect, which has become quite troublesome in Santa Clara County, resembles the Eastern crown-borer of the peach, but is a distinct species {Sannania pacifiea, Riley). The.
