The Mealy Bug, as it is generally called, is a white mealy or downy-looking insect, which is often very troublesome among hot-house plants, but rarely does any harm amongst those that can live in a cool room, as no doubt it is a native of some tropical country, and can only exist in such a temperature as is required by plants of that kind. There are various remedies used by florists:, but the use of nearly all of them might do more harm than good in inexperienced hands, and I therefore advise that they should only be destroyed by being washed off such plants as Gardenias, or rubbed off of more tender leaved plants with a soft brush; or where there are but few, they may be readily picked off by the use of a quill sharpened like a toothpick.
