96 DESTRUCTIVE INSECTS OF VICTORIA: 



the tree becomes sickly and dies. (Our plate will show 

 to what extent these larvae will injure the limb of a tree. ) 

 Our forests tell a pitiable tale of the damage done by 

 these and other boring insects. 



The color of this beetle is mostly steel-blue, legs and 

 all ; the male being much smaller than the female. 



Prevention and Remedies. 



In small holdings, and with valuable trees planted 

 artificially, these borers can be kept off by means of a 

 spraying with kerosene, &c., as a deterrent; but, when 

 trees in a forest are attacked, the only way is to cut them 

 out, if beyond redemption, and burn them on the spot 

 or as near to it as possible. 



In the European forests, where labor is cheap, as also 

 in India, great attention is paid to forest insects, and no 

 expense is spared in combating the evil. In Victoria 

 we could hardly afford extensive measures, and are 

 thankful if we can but protect our orchards. 



So far this beetle has never been known to attack 

 introduced fruit-trees ; and I do not think there is any 

 likelihood of its so doing.
