Through a Pocket-Lens. B)- Henry Scherren, F.Z.S. Cr. 

 8vo, pp. 192. (London: The Religious Tract Society. 1897.) Price 2/6. 



The author here points out how much may be seen with an ordinary pocket- 

 lens and with a simple microscope, and endeavours to dispel the far too common 

 idea that no real work can be done unless one has a compound microscope, 

 with a large battery of lenses and an array of accessories. 



The subjects treated of are : The Pocket-Lens, Dissecting Microscope, and 

 some simple appliances ; Arthropods and their Classes ; The Common Water 

 Beetle, Great Water Beetle, and Cocktail Beetle ; Cockroaches, Earwigs, 

 Great Green Grasshopper, Water Scorpion, Water Boatman, Corixa ; Spiders, 

 Mites, and Myriapods ; Crustaceans — Prawns, Shrimps, Mysis, Crabs, Aniphi- 

 pods, and Isopods ; Aquatic Insect Larvae. There are 90 illustrations. 



The Young Beetle-Collector's Handbook. By Dr. E. 



Hofmann ; with an Introduction by W. Egmont Kirby, M.D. Cr. Svo, pp. 

 viii. — 178. (London: Swan Sonnenschien and Co. 1897.) Price 4/6. 



We have seen no better book for the young beetle-collector than this. It 

 contains 20 coloured plates comprising over 500 figures. Besides a general 

 and thorough description of all the various genera and species, we find chapters 

 on the Structure, Development, and Habits of Beetles ; How to Kill Them ; 

 and How to Arrange the Collection. The plates are beautifully coloured and 

 the collector will have no difficulty in identifying his captures. 



Handbook to the Lepidoptera, Vols. IV. and V. ; being 

 Moths, Parts 2 and 3. By W. F. Kirby, F.L.S., F.Ent.S., etc. Crown 8vo, 

 pp. xlii. — 246 and xii. — 332. (London: W. H. Allen & Co. 1897.) 6/- each. 



These two volumes complete the series on the order Lepidoptera. Vol. IV. 

 describes the families Sphingida, Bomhycidiv, Brah/nteidcB, Drepaiitilidoe^ 

 CeratocafnyidiES, Satitrniidce, Lasiocampidcc, Megalopygida, Eupteroptidce^ 

 PinaridcB, Zeuzeridcc, Arbelidce, and Hepialidcz. Vol. V. contains descriptions 

 of the NoctUiV and Geometrce among the larger moths, and the Micro- Lepidop- 

 tera. Of these latter, which probably exceed the Macro- Lepidoptera in 

 numbers, it has been found impossible to do more than describe and figure a 

 selection of species belonging to the various families. In these two volumes 

 there are 63 good coloured plates.

 Sharpe, L.L.D. Vol. IV. Crown 8vo, pp. xviii. — 312. (London: W. li.

 of excellent coloured plates (31 in the present volume) besides a few engrav- 

 ings in the text.
