Annual report of the Fruit Growers' Association of Ontario, 1904 . Fig. 13. Fig. 14. Mr. Albert F. Winn, of Westmount, P. Que., has found upon oak treeson Mount Roj^al specimens of the fine moth, Prionoxystus Macmurtrei Guer-in-Meneville. The larva of this species is known as The Lesser Oak Car-penter Worm. A great variety of beetle-grubs are miners in the oak, and are veryinjurious to it, Buprestidce, Curculionidce, Cerumbycidce, Scalytidce, etc. The specimen I exhibit is Urographis fasciatus, De Geer, one of theCerambycidse. The species to which it belongs is found throughout theUnited State

With this she pierces the outer layers of the bark of the oak, thatshe may deposit her eggs in the softer layers within. The larvae tunnel in the bark close to the white wood, and pack theirpassageways so full of fine frass that it is hard to trace them. The beetlesappear early in June. The larvae and pupae should be looked for earlyin the spring. It may have been to this beetle that the damage we n
