influence. It is in osier cultivation that it proves most dangerous 

 and it should be destroyed when noticed by hand-picking or 

 spraying. 



Pissodes notatus, Fabr., ravaging Austrian Pines. 



Damage to Austrian Pines by the Banded Pine Weevil {Pissodes 

 notatus, Fabr.) has been reported by Mr. Pi. Hyne and others during 

 the past year. 



According to the reports of Continental foresters, Pissodes notatus 

 almost exclusively follows the Pine Weevil {HyloUus ahietis, Fabr.). 

 It is usually found on trees rendered unhealthy by the Hylohhis and

finishes the damage begun by that beetle. Pissodes notatus occurs in 

 all manner of places, in wood split for fuel, in young living stems, in 

 pine cones and in the bark at the base of old trees. The chief 

 damage it does is where it attacks young unhealthy trees. Planted 

 pines suffer more than those self-sown, (1) because the planting 

 often throws them back, (2) on account of the crowding in the nurseries 

 which makes the young trees sickly. The Pissodes chiefly feeds then 

 on trees attacked by the Hylohius and those gro"\^Ti on unkindly soil and 

 thus more or less unhealthy. If the supply of unhealthy trees fails 

 then these beetles will attack sound ones. 



The beetle (Fig. 13) is about one-thiixl of an inch long and of a 

 reddish-brown colour, irregularly covered with bright haii^s ; the pro- 

 thorax has eight yellowish spots ; the elytra ^vith two broad pale bands 

 running transversely across them. The beetles appear in April and
