in the net; the overhanging heather made it difficult to use one's net clc inly, and 

 the Pompilus was too smart, but the bugs were heavy, and from their appearance 

 no doubt been well stung. Mr. Edward Saunders has very kindly examined my 

 specimens, and pronounced the Pompilus to be Salius parvulus, and the bug 

 Ali/dus calcaratus ; but as Salim pusillus was also taken in the same spot it is very 

 probable that this species also was engaged in bug-hunting. 



The following captures at Minehead may be worth recording, Mr. Saunders 

 again most kindly naming my specimens : — Pompilus cinctellus, Spin., ? ; Salius 

 parvulus, Dahlb., 9; S. pusillus, SchiSdte, $; Agenia variegata,lA\m.,^ ; Cero- 

 pales maculata, Fab., ? ; Asfatus hoops, Schr., ? ; Nyssoti ?>-maculaf,us, Rosse, ? 

 (four specimens) ; Entomognathus brevis, V. de L., $ ; Crabro littiratus, Panz., ? ; 

 C. interruptus, De G., £ ; Yespa norvegica, Fab., $ ; Megacltile versicolor, Smith, 

 ? ; M. ligniseca, Kirby, $ ; Lasius fuliginosus , Latr., strong colony in large oak 

 tree; Hedyvhrum roseum.— G. A. James Rothney, Pembury, Tudor Road, Upper 

 Norwood : June 1th, 1908. 



[The capture of Salius parvulus conveying an Hemipterous larva is most in- 

 teresting. I have never before heard of any of the Pompilidx capturing Hemiptera ; 

 and Professor Poulton, who is collecting records of Hymenoptera and their prey 

 tells me that he does not know of any such case. Hemiptera are well known as the 

 prey of Astatus, a genus of Sphegidie, red and black insects, somewhat resembling 

 the Pompilidse in general appearance, though very dislinct in structure — E. 

 Saunders].

Forest Entomology : by A. T. Gillanders, F.E.S. With 351 Illustra- 

 tions. 8vo. Edinburgh and London : William Blackwood and Sons. 1908. 



The influence of insects on the well-being of such of our old woodlands as yet 

 remain, and still more so on that of the new plantations which are now being 

 established in all parts of the British Islands, is so great and evident, that it must 

 claim the serious attention of every one concerned with their care and management ; 

 and the ability to recognise the various forms of insect life which attack and destroy 

 arboreal vegetation, as well as a competent knowledge of the methods of dealing with 

 their ravages, form an indispensable part of the equipment of the modern forester. 

 Hitherto, although there is no lack of excellent treatises on the subject by Con- 

 tinental and American authors, we have had no book entirely devoted to economic 

 forest Entomology by an English writer ; and in this respect the present work, in 

 which the extensive practical experience of Mr. Gillanders is embodied, is especially 

 welcome. After a brief introductory sketch of the principal Orders of Insects, and 

 an interesting account of the frequently destructive " gall-mites" {Eriophyidx), the 

 insects known to be more or less injurious to forest growth are considered in detail, 

 commencing with the Coleoplera. In this as in the other Orders, it is safe to say 

 that no species is omitted with which the forester may be concerned ; in fact a good 

 many are included, which, however plentiful and destructive they may be abroad, 

 are here of only rare or casual occurrence ; though, as in the case of the remarkable 

 beetle Xyleborus dispar, they may in isolated instances give rise to a certain amount 

 of damage. In each species the life-history is clearly described, and in nearly every
