246 CERAMBYX SP. 
CERAMBYX SP, 
Order, COLEOPTERA. Family, Cerambycidz. 
Trees attacked :—Pinus excelsa (Blue pine) ; Picea Morin- 
da (Spruce), 
Following close upon the Tomicus attacks and appearing 
sometimes with them, when these latter insects have weakened 
the tree by their onslaughts, numerous Cerambyx larve are to be 
found at work, making broad, shallow galleries in the bast and 
outer sapwood. These larveare white in colour, resembling those 
already described on page 50 in No.1 of these notes (see Pl. IV, 
fig. 3, a) and were from 1 inch to 14 inch in length at the time 
they were found. No perfect beetles have yet been obtained. 
These longicorn larvae are dangerous in the forest since their 
attacks further weaken the trees and minimise or entirely put 
an end to any chance they might have had of recovering from 
the bark beetle infestation, Further information is required on 
the following points :— 
(1) As to how long the insect spends in the larval and 
pupal stages. 
(2) At what time the mature beetle apvears.
