Phoracantha recurva, Newm., is common in Ne"W South Wales in 

 Eucalyptus novae-angliae and E. rostmta. Observations made in the 

 month of February showed that eggs are deposited upon the bark of 

 fallen branches of E. rostmta in irregular rows. Newly emerged larvae 

 were found on 8th March. Feeding takes place for several months 

 under the bark, but later the larvae enter the deeper layers of the wood, 

 in which position pupation takes place. It is parasitised to an extent 

 of 70 per cent, in the larval stage, and is thus prevented from becoming 

 a serious pest of timber. The Clerid, Trogodendronfasciculatum, is found 

 in the larval stage in the galleries of P. recurva. The eggs of this parasite 

 are probably laid upon the bark, and the larvae, upon hatching, work 

 their way into the galleries of the host. Adults emerge in October 

 and November. The Braconid, Iphiaidax rubricejjs, sp. n., which also 

 attacks the larva, is widely distributed in Australia ; related species, 

 I. pJioracanthae, sp. n., and 7. morleyi, sp. n., have been reared from 

 cocoons found in the galleries of this Longicorn. Betlielium munda, 

 Blackb., is widely distributed in Tasmania and Australia and in the 

 larval stage bores into the small branches of E. novae-anglicae, causing 

 them to break off. The w^hole of the larval and pupal stages, occupying 

 at least two years, are passed within the branch. Where preventive 

 measures are worth while, it would be possible to reduce the numbers 

 of these beetles by burning the fallen branches.
