to the serious nature of the ravages of the Colorado beetle (Doryphora decem-lineata) in the United States during the past few years, and to the still greater damage caused by the Phylloxera in the vine-growing districts of France. Had we possessed a full acquaintance with these insects at the outset of their destructive career, it is probable that much of the subsequent loss and ruin would have been avoided.

The Rev. Dr. Purchas said that several insects were being gradually introduced that would ultimately prove very undesirable colonists. For instance, a wood-borer—the name of which he was not acquainted with—was a most pernicious species, perforating the wooden lining of houses until it crumbled into a mass of dust. He had also seen furniture attacked by it.
