“Notes on Wood-Feeding Coleoptera,” by Joseph Side- 
botham, Esq. 
The number of species of coleoptera that feed upon wood 
in this country is considerable, some attacking growing 
trees, others when cut down or partially decayed, others 
attack solid timber when cut up and used for buildings or 
furniture. The various species are not confined to one or 
two of the great divisions, but are to be found scattered 
through most of them, being found in the sections Necro- 
phaga Lamellicornes, Sternoxi, Malacodermata, Rhynco- 
phora, and Longicornes, &c. 
As might be expected, their modes of attack on trees are 
as varied as their organisation, and their study is one of 
great interest to naturalists, besides being of the greatest 
importance to the owners of plantations and forests. Some 
species mine in the bark, others between the bark and the 
solid wood, others in roots and branches, and there are few, 
if any, of our native trees that are not liable to attacks from 
one or more species. 
The amount of damage done to a forest when a few 
species get fairly established in it is very great, and too 
often the woodpeckers, which would assist in checking their 
ravages, are destroyed, because they bore holes in the trees 
to get at the insects.
