One of the most trou- blesome is the "strawberry-weevil," A. signatus, which appears as a small, blackish beetle, with gray pubescence, when the buds are developing, and lays an Ggg in each, afterward puncturing the flower-stalk be- low the bud so as to check development. The larva feeds upon the pollen in the unopened bud, and finds it sufficient to attain its full growth, changing to a beetle in midsummer. The insect attacks a number of other flowers in the same way, not even confining itself... to one natural family, and its injury to straw- berries is of a somewhat intermittent character, becoming worse for a number of years, then stopping suddenly for no apparent reason. Only staminate, or pollen-bearing, varieties are attacked, and the Sharpless is, perhaps, the most seriously infested. By planting chiefly pistillate varieties, the staminate rows may be protected by cheap coverings until the buds are ready to open, and even if a small Rhubarb-beetle, Lixus concavus. —a, its larva ; b, pupa.
