Annual report of the Regents . haveclearly shown, what had before been reported, that its ovipositionand borings, are not confined to the base of the tree, but that theyalso occur at various heights upon the trunk and extending upwardeven into the base of the main branches. It will therefore be seenthat the application of washes or wraps to the base of the trunk,generally recommended, does not give complete protection from theinjuries of this pernicious borer. For an account of the oviposition of the beetle, reference may bemade to my Fifth Eeport, 1889, pp. 127-129 (269-271 of the StateMuseum
