From theclinging nature of the web the operation took some time tocarry out completely, but I have myself thus cleared andcleaned a tree very satisfactorily. The various Avashings recommended for remedy of Lackey SMALL ERMINE MOTH ; MUSSEL SCALE. 297 Moth attack would be as serviceable for that of the SmallErmines, and in both cases good drenchings of soft-soap,mixed as thickly as it could be applied (with a little paraffinadded), well syringed at each web-nest, would have a verygood effect. It has been observed that the whole brood of moths usuallyhatch from the chrysalis at the same time, when_ their lightcolour makes them easily seen, and they are sluggish by day;it has therefore been found useful to spread a sheet under thetrees, and by beating or shaking the boughs make the mothsfall into the sheet, and destroy them. Mussel pomoritm, Bouche ; Aspidiotus conchijormis, Infested Apple twig. Female Scales showing female and eggs; and also femaleslirivellcd within the Kcale; much magnilied. The Mussel Scales are so named, in this country, from theirresemblance to very small Mussel shells. The infestation is very widely distributed. It is found inEurope, N. America, New Zealand, and Tasmania, Init up to188G was reported l)y Mr. Frazer Crawford officially as nothaving then l^een noticed in S. Australia. The Coccus infestsmany kinds of trees and shrubs, but with us it is especiallyinjurious to the Apple. Some kinds are more liable to attack than others, and inmy own observations I have found the Wellington especiallysubject to this infestation. The injury is caused by the littleCocci in the early part of their lives inserting their rostruni orproboscis into tlie tender bar
