I may remark that all insects that feed onthe leaves of plants maybe disposed of in this way, whether they are larvae of butterfliesor moths, or whether they are beetles, the hellebore being used in the proportion of twotablespoonfuls, and Paris green in the proportion of a teaspoonful to a pailful of water. Itis well to use a little hellebore and water or Paris green and water, whenever the leavesare eaten from any cause. THE SPOTTED PELIDNOTA.

During the past seasonit has been greatly complained of, having almost entirely destroyed the grape crop in somelocalities. It attacks the vine just as the buds are swelling, and although it is a smallbeetle, not more than three-twentieths of an inch in length, it is rather voracious for [Mr. W.
