Green Beetle (Dipliucephala collaspidoides). This is a very trouble- 

 some insect in various parts of Australia, and more particularly in sandy 

 soils. It belongs to the well-known " Cockchafer " family, a very 

 destructive class of insects in European orchards. Green beetles make 

 their appearance in great numbers, rapidly destroy the leaves of any 

 trees they may attack, and they specially affect Cherries and Plums. 

 The insect is about one-third of an inch in length, and in colour a 

 bright shining green. It usually makes its appearance in the early 

 summer and remains till the end of the year, when it lays its eggs and 

 dies. Remedies : Spraying with kerosene emulsion, Bordeaux. Mix- 

 ture, and tar water will help to destroy them, as will also boiling water. 

 Sulphur fumes will cause them to drop from the trees, and when lying 

 on the ground they may be destroyed by rolling, beating, or burning. 

 The insects should be invariably attacked while young, being then more 

 easily destroyed. 



Mealy Bug (Dactylopius), various species. A well-known and very 

 troublesome small insect, which is covered with a thick powdery sub- 

 stance, hence its common name. It is often troublesome to Oranges and 

 other evergreen trees. Remedies : Kerosene emulsion and strong 

 tobacco water sprayed over the trees.

 insects, about half-an-inch in length, and richly maiked with yellow, 

 orange, red, and black. They are natives of Australia, and with other 

 species of the same family are widely distributed. They are said to 

 cause trouble by puncturing the skins of Apples, extracting the juice, 

 and causing the fruit to spot. Remedies : Use lime freely, and tar 

 water ; also shaking the trees, to cause the insects to fall, collecting
