accurately made out :— 
The season at which the perfect beetles appear. This will prbbébly 
stand in some relation to the and wet seasons. 
‘The Aabits of the perfect beetles, their flight time, place of rest.

diseased trees, &c. 
The place at which they oviposit. This is of importance. Probabl 
oviposition is favoured by wounds in the bark. Special attention should 
be paid to the probability of the eggs being laid at pruning etiem and 
the system of pruning adopted sho juld be looked to with this ob ject. 
The length of larval life and the length of time a tree will withstand 
injury without succumbing should also be investigated, 
The early signs of injury should be carefully made out, in order that 
infestation may be detected as soon as possible (see p. 1 3). 
General Suggestions. 
The following general Sngecetions for treatment over and above those 
already given are based mainly on the assumption that information will 
be gained on the Aor points in par. 4 :— 
Prevention of Egg-laying. 
All pruning and accidental gines vog be tarred. 
Possibly egg-laying may be prevented at the usual situations by 
plastering the part of the bark Meca selected for the purpose with 
clay and eow dung, or a similar mixture, or painting it with lime-white 
mixed with rice water, i make it adhere. "This treatment has proved 
successful with other species of borers. qp ; 
Capture of the perfect Beetles. 
This to be successful — be et qaa after study of their habits 
and time of appearance. may be don 
a.) By placing sheets uer On pistes “ahd shaking off the beetles, 
in the early morning or whenever they are so slugg gish as to drop. The 
beetles should then be collected and killed with boiling water. 
A convenient plan of collecting them from sheets is to fit a tin bucket 
with a wide funnel-shaped lid of tin, furnished at the centre with a short 
tube. The sheets are shaken on to the lid, the beetles drop through 
the tin tube, and cannot escape until the lid is removed. 
(b.) By setting baits for them, and collecting them from the baits. 
This cannot à done unless their habits show that some kind of bait - 
serve to attra 
c.) By providing logs of any tree which they will attack, ringed 
trees, coffee shru ich have been condemned and are dying or have 
been ringed for iiem i lay their eggs in hese * tree traps" should 
be provided before the flight period and ‘removed before the beetles in 
them have bred out, or they will do more harm than goo
