1920. telephone cables damaged by wood borers. In Agr. Gazette N. 



5. W., v. 31. pt. 5, p. 344. May. 



A suspension of the telephone service was caused by water reaching the wire 

 through small holes bored by the beetle, Bostrychus cylindrical. Cables have fre- 

 quently been attacked in the same way, and an instance of similar injury due to 

 another Bostrychid has already been noted (Froggatt, 45). B. cylindricus is one 

 of the commonest Australian wood-boring beetles, attacking all kinds of timber ; 

 but the larvae usually feed and pupate in the sapwood. The beetle has been 

 recorded as damaging empty wine-casks. The boring in lead seems to be casual, 

 and no practical method of dealing with it has presented itself, except to de- 

 stroy any poles, etc., in which the larvae were found to be breeding in any 

 numbers.
