The bud is assailed assoon as it makes its appearance by the caterpillars ofsome species of little moths of the family Tortricidae,which fasten the young leaves and buds into a masswithin which they also take their ease in their owninn. All these insects are, however, more or lessvisible to the observant Rose fancier ; but the insectwhose proceedings we are now to describe is far moreobnoxious, as it completely conceals itself until themischief which it effects is completed, and its presenceis only made known when the bud which has escapedits numerous foes, and is just ready to reward thecultivator, suddenly falls down, on the slightest breeze,. just as when rude hands the twin buds sever. Thecause of this sudden and unexpected breaknge of thestem is a small caterpillar or grub of a species of saw-fly which, having entered into the stem of the bud atone of the eyes, has eaten is way downwards, con-Ruming the pith of the plant, and forming a cylindricalburrow down the centre 2 or 3 inches long. It isduring the month of June that this mischief is chieflyeffected. I have found the larvae in this position onthe 3d of June in the stems of the buds, but during thewinter alHO they may ho found in the pith ol Rose snagsand doad Rose stumpH, rcHc-mhling in this respect thesmall black caterpillars of a Tortrlx, whose history Itrust to complete for illuntration in our entomologicalH-ricB.
