The Red Scale {Aspidiotus rossi) : This pest must not he confusedwith the Red Orange Scale {Aspidiotus aurantii). It belongs to thegreat family coccididse. the members of which are responsible for a greatamount of damage every year to both fruit and ornamental trees. It isone of the most common of the scale here. It appears to flourish some-what better in the coastal regions than in the inland areas; this is due, inpart, perhaps, to the presence of more succulent vegetation, more equableconditions, and the greater shelter in the dense foliage of .southern wood-knds. This scale differs considerably from Lecauium olca, inasmuch as itappears to secrete very little honevdew, very little of theblack fumagine that lives on this secretion, and is so conspictious a featureof the latters presence, is OLIVE LEAVES SHOWING ATTACK OF SOOTY MOULD. The treatment adopted for the Black 01i\e Scale should be appliedjilso for this one. -The White or Oleander Scale {Aspidiotus nerii) : This scale sometimesattacks the olive as well as a number of other evergreen trees. It has avery wide distribution, and is very hard to dislodge when once vi^ell estab-lished. It is greyish white in colour, often changing to greyish scales are about i-25th to i-i2th of an inch in diameter. The female-puparium is almost circular and somewhat larger than that of the male,which is small and elongated. Owing to the absence of the ScotvMould Fungus with this and Aspidiotus rossi. it is more difficult todetect an early attack than in the case of, for instance, Lecanium once they are discovered, however, no time should be lost in apply-ing the most effective remedies. Treatment.—This should be carried out with contact spravs or fumiga-ti
