46 DESTRUCTIVE INSECTS OF VICTORIA : 



Prevention and Remedies. 



In dealing with matters of this kind, one cannot but 

 recommend a constant vigilance, particularly if the plants 

 are situated in or near Murra}^ Pine country. Should the 

 upper branches, especially, show traces of turning yellow, 

 the trees should be at once examined ; if carefully looked 

 at, tiny holes may be seen, and probably the beetles may 

 be emerging, as shown on the plate (Fig. I.). In such a 

 case, the holes should be probed with wire dipped in 

 bi-sulphide of carbon, leaving the wire in the holes. This 

 could be done by a boy, and would be effective.
