Forest Entomology. By A. T. Gillanders, F.E.S., Wood 

 Manager to the Duke of Northumberland, xxii + 422 pp., 

 including Index. 351 Illustrations. Blackwood & Sons, 

 Edinburgh, 1908. Price 15s. 



Some years ago, at one of the dinners of the Royal Scottish 

 Arboricultural Society, the cover of the menu card, skilfully 

 drawn, showed a German forester driving injurious insects out 

 of his wood at the sword's point, a British forester being depicted 

 lying asleep and unconcerned while the insects attacked his 

 trees. If the artist wished to convey the lesson that more took 

 place in the wood while the forester slept than the " growing 

 of the tree " in the Society's motto, and that it behoved the 

 forester to be on the alert against insects, we can declare, with 

 perfect certainty, that the reproach has lost much of its point, 

 for the importance of the study of Forest Entomology is now 

 widely recognised. That our foresters only need some en- 

 couragement to make good use of their opportunities has been 

 well proved true by numerous and useful notes and articles 

 on entomological subjects which have recently appeared in the 

 Transactions of the Society. And now we have, in this book 

 of Mr Gillanders, the latest proof of the advantage of, and 

 interest in, the subject of Forest Entomology. 



Chapter I. gives a resume of the Eriophyidae or Gall Mites, 

 the various species of importance in Forestry being described 

 in detail. The next two chapters treat of the Beetles, these 

 extending, as the importance of the order warrants, to almost 

 one hundred pages. Chapter IV. treats of Oak Galls, and 

 Chapter V. of other harmful Hymenopterous Insects — the 

 Sawflies and the Wood Wasps. Chapter VI. treats of Scale 

 Insects; Chapter VII. of Moths; Chapter VIII. of Aphididse ; 

 Chapter IX. of Diptera ; Chapter X. of Psyllidae and Cicadidae ; 

 while concluding chapters give hints on collecting, on Insecti- 

 cides and on Beneficial Insects.
