Should thiy occur in injurious numbers at any time, they may be K"t rid of with the lime-sulphur wash. .APfLE-THEE BoREHS. The Roixd-Heaoei) Bokeh (Saperda Candida), Fmj;. j<) IS a very serious enemy to youn^ trees. The parent beetle is a hand- some insect of a chocolate brown color with two bands of chalky-whito cxtendinR' from one extremity to the other on the upper surface and with lonjf jointed antcnnw. The female lays her eRffs in an incision which she makes in the bark during the month of June; the young larv» tunnel under the bark and feed upon the sap-wood, living for thice years in that condition, and making larger and deeper burrows as they increase in size. Their presence may generally be ascertained by the little heap of sawdust- like castings at the base of the affected tree. Working under cover as they do, they cannot be reached by ordinary poisons, and can only be destroyed by the insertion of a wire into their boring, or by cutting out with a knife. The former operation is somewhat uncertain, and the latter may injure the tree to a serious extent. The only safe remedy, then, is to prevent the adult from laying its eggs upon the tree.
