XCIIl THE CL4NADIAN ENTOMOLOGIST LOSS used primarily as an area sampIer, the results map be expressed in terms of volume by recording also the depth of the water and the debris. The cage may he reas~embled into a more compact unit for carrying by removing the sorting travs, rotating them laterally through 180 degrees and placing them over the enclosure as shown in Fig. 1, L. The trap braces (I) are fastened in altcrnate positions to hold the twvs onto the enclosure as a lid. When reassembled thus, the cage could also bk used as an emergence cage for mosquitoes and other aquatic Diptera simplv hy providing a sleeve on a reinforced olpening in a convenient side franie. A sponge rubber gasket (K) ensures a seal hemreen the nvo halves of the lid.
Book ReviewsDer Kafer. Ein Wunder der Schiipfung. By Ewald Reitter. 206 pp., 3 figs. and 59 plates. 34 x 24 cm. Chr. Belser Verlag, Stuttgart, 1960. Price 80 DM. This book is a fine example of virtuositv in colour photography and printing applied to beetles. With one exception thk subjects are dead and pinned specimens, although this is rarely obtrusive, selected for the most part: for showiness and size. With this in mind it is not surprising that two thirds of the exampIes are from the Scarabaeidae or Cerambycidae; other groups represented include the Adephaga, Chrvsomelidae, Anthribidae, Brenthidae and Curculionidae. The insects appear to hive heen photographed against a background of ~vliite foamed plastic with lighting arranged to give a rather weak shadow wllich relieves some of the flatness usuallv seen in photographs from pinned specimens. T h e reproduction is above reproach. The onlv photograph from life, and perhaps the finest picture in the book, is of the larva of ,\4egnsoma gyas Hbst. which, at twice life size, occupies a full page. From one to ten specimens are reproduced on each right hand page. The Latin names with their meanings in German, German common names, size, sex, distribution and brief notes on the species are printed on each facing page.Despite the sub-title and introductory quotation from the Bible most of the text, although rather elementary, is quite modern in outlook, and covers such topics as structure, evolution from the primitive insect, development, sexual dimorphism and perhaps too generously, beneficial and harmful beetles. The classification used however is that of Handlirsch, 1923, and there is no precise systematic arrangement of the plates.The plates are followed by an appendix on the history of the study of beetles, articles on how to collect and prepare them, an index to common and Latin names and an index to authors and journals.B.
