Insects Hurtful to the Rose.

Roes culturists are frequentlydisappolnted in the result of their labors, by seeing the foliage and flowers of their favorite plants eaten by inscets which appear to baffle all attempts to destroy them. One of the most destructive inscets, the rosesing, is the larva of a saw-fly. (Selandria rota), which so closely resembles the slugworm as not to be easily distinguished Atom it These saw-flit a come out qf the ground at various times between the 20U» of May and the middle of J upmediately lay their eggs by thrusting their saws obliquely into the skin of the leaf, and depositing an egg in each incision. When the young slugs are produced from the eggs, they eat the upper surface of the leaf In irregular patches, leaving the vein and the akin skeletonized. They cast their skins several times, and finally drop to the ground, and barrow into the soil the depth of an inch or more, forming little oval cells, cemented with a little, gummy* nlk. Having performed their transformation and become fibs, they emerge from the ground early in August and lay their eggs for a second brood. These enter the ground late in the frill, and remain in their cells until the ensuing spring or summer.
