On this honey-dew grows often a minute fungus,which gives it a dark colour and frequently forms black patches on the withering leaves. At the same time there could be seen hanging from the twigs, and here and there upon the limbs, fluffy cottony tufts, pure white in .^.T=^»^ ,„^r7^^^^^^ colour; these are the female scale insects "^^^'"'""^-_-^-_- ^ which cover their masses of eggs with this waxy substance. (Fig. 9.) A single individual produces one or two thousand eggs ; when hatched the minute larvae swarm over the nearest twigs and leaves for a few days and then fix themselves permanently on the under side of the leaves, attaching themselves closely to the ribs ; a few may occasionally be found on the upper surface and on the twigs After a short time a waxy scale is formed, oval and convex in shape, completely covering the tiny insect. The insect is called the Cottony Maple Scale (Puhinaria innvmerabilis, Rathv.), but is found upon a large number of other trees, and in London seemed to be more abundant upon the basswood (linden) than upon the maple, judging from the extent of the stains beneath the former trees and the drooping appearance of their leaves.
