We would, therefore, earnestly impress vipon our fruit-growing readers the isractical import- ance of examining all barrels or other vessels, in whicli apples liave been stored through the winter; and if, as will generally be the case, they are found to be swarming with Apple- worm cocoons in the spring, let them be either burnt up at once, or thoroughly scalded by im- mersing them iu boiling hot water for a few minutes. THE ASPARAGUS BEETLE (Crioceris a&paraiji, Linn.) There is scarcely a vegetable raised in our gardens that is not preyed upon by one or more grubs, caterpillars, or maggots, so that, when we eat it, we have positively no security that we are not mingling animal with vegetable food. Two distinct kinds of maggots, producing two distinct species of two-winged Fly, burrow in the bulb of the onion. Scabby potatoes are inhabited by a more elongated maggot, produc- ing a very difierent kind of two-winged Fly, and also by several minute species of Mites. Turnips,' beets, carrots and parsnips are cacli attacked by peculiar larva?. And as to the mul- tifarious varieties of the cabbage, not only arc they often grievously infested by the Cabbage riant-lousc—a species which has been intro- duced from Europe into this country—but also by an imported caterpillar prcdncing a small moth, and by several indigenous rateriiillars producing mucli larger moths, some of whicli caterpillars, wlien full-grown, arc over one inch long.
