beaks to suck out the sap. They grow rapidly, occasionally 

 molting or shedding their skins to provide for their increase in 

 size, and in the course of a month become mature. 



The first summer brood thus developed deposits eggs on 

 the underside of the leaves. These eggs hatch ten days later, 

 and mature in about three weeks. The insects of the second 

 brood suck the sap from the leaves. There are several of 

 these summer broods, the number varying with the locality 

 and length of season. In early autumn the dark, hibernating 

 winter form is developed. 



The sap which passes through the bodies of these little 

 creatures is ejected on the foliage, and forms the so-called 

 " honeydew." Where the insects are very numerous this 

 becomes very abundant, falling in showers when the branches 

 are disturbed. After the honeydew has been present for some 

 time a peculiar black fungus develops upon it, and gives the 

 tree a sooty appearance. 



Professor Slingerland makes the following statement con- 

 cerning the indications of the presence of the pest : i 'Among 



The Luna Moth (slightly reduced).
