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 Remedies. noticed later, the whole cane should be pulled up and destroyed, to be sure 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 th
