Collection of Bark Beetles—Dr. J. W. Munro, Entomologist 
of the Forestry Commission, has placed on loan in the Forestry 
Museum at Kew an almost complete set of workings of beetles 
which feed upon the inner -bark and outer wood of trees in the 
British Isles. On the different sections of wood and bark the 
galleries peculiar to each beetle are well defined, and students 
are afforded a good opportunity for comparing the workings 
of allied insects. At the same time, the collection of bark beetles 
bequeathed to Kew, with other insects, by the late Mr. A. T. 
Gillanders has been rearranged and added to, so that Kew now 
possesses a very comprehensive collection of bark beetles and 
their workings. The collection includes the following species :—
