tered, spruce pre- 
dominating.

Cocoons 
numerous 
H. ater adults 
and larvae, 
H. palliatus 
adults 
The wood was com- 
posed of Scots pine 
and larch, Scots 
pine predominat- 
ing. The area has 
been irregularly 
felled, so that stumps 
yielding cocoons are 
scattered.

Rkagium in- 
dagator adults 
and larvae 
Bracon is here en- 
tirely absent. The 
wood is pure Scots 
pine. Rhagium 
larvae were as plen- 
tiful as Hylobius 
grubs — an unusual 
occurrence.
