Protection and remedies. 
Until more is known about the life-histories of these two 
Cerambycid beetles, it is difficult to prescribe remedies against 
them. Badly infested trees should, however, be cut out whilst 
the insect is still in the grub stage and the bark stripped off so as 
to expose the cambium and sapwood of the tree to the sun. In 
this position the grubs and pupz will soon be killed off and will 
never reach the beetle stage. This must be done whilst the 
insect is still in its larval stage. Ifleft too late the beetles will 
begin to emerge and many will escape and lay eggs in adjacent 
trees. 
The same applies to trees whose roots are attacked, The 
earth should be removed round the larger of these latter, since 
it is in these that the grubs will be found, and the bark be then 
stripped off. 
Points in the life-histories requiring further observation. 
1, Where the eggs are laid by the beetles, 
2. When do the young larve hatch out ? 
3. Length of time spent by the larve feeding in the cam-: 
bium layer and sapwood. 
4. Length of time spent in the pupa stage. 
5. When does the beetle emerge? Is it only towards 
the end of May and beginning of June, or do 
beetles appear at other periods in the year? 
6. Does the Lamza grub also attack the stem of the tree ?
