the tip of the cane to wither. A short tiine after the egg is deposited it hatches into a small 

 cylindrical larva, that bores downwards through the pith. By autumn they have frequently 

 reached the bottom of the cane, where they change to pupse, and the following June emerge 

 again as beetles. The larva is footless. 



Soon after the canes are punctured by the beetle they wilt; consequently, if they are 



examined about midsummer, affected canes can easily be distinguished, and they should then 



be cut off below the lower ring of punctuVes and burned. If the injury is

and get the larva. 



This pest {Betnbicia marginata) has become very prevalent in the vicinity of Victoria, 

 where it has wrought great damage to the raspberry canes. It is not reported from other parts 

 of the Province. It is quite distinct from the cane-borer, having in the larval 

 Raspberry state sixteen legs, six of which are fully developed, the others not being very 

 well defined. The parent moth is clear-winged, with a black body, prettily 

 banded and marked with yellow. The eggs are deposited in July on the leav'es of the rasp- 

 berry, and the young larvie, when hatched, find their way to the canes and feed upon the pith 

 in the interior, gradually working down to the root, where they winter. In the following- 

 spring they work up again, usually through a fresh cane, to a height of six inches or more above 

 ground, and eat the cane nearly through, in preparation for the exit of the future moth. 

 Within the cane and near this prepared spot the change to chrysalides takes place, and these, 

 when the time approaches for the moth to escape, burst through the outer skin of the canes, 

 and the moths soon take their flight and commence to lay their eggs, as previously stated. 



Little can be done towards the destruction of this pest, other than destroying the infested 

 roots as soon as they are noticed. The application of boiling water to infested roots is advised 

 by a California writer.
