264 ANNALS OF SCOTTISH NATURAL HISTORY 



The Senses of Insects. By Auguste Forel. Translated by 

 Macleod Yearsley, F'.R.C.S. London, Methuen »\: Co., 8vo., xiv 

 and 324 pp., 2 plates. Price los, 6d. net. 



After the numerous systematic treatises on insects which have 

 been recently published, and which must be mainly used as books 

 of reference or merely for the identification of specimens, it is 

 refreshing to take up a volume wliich can be read with interest 

 from beginning to end. Such a work is that which lies before us, 

 and the entomological public owes much to the enterprise of the 

 publishers and the energy of the translator, through whose efforts 

 we can with ease learn the latest views on a difficult but fascinating 

 subject, and read a detailed account of the experiments of one who 

 is regarded as an authority on the various senses and instincts of 

 insects. The twelve chapters into which the work is divided 

 contain a lucid and detailed account of experiments conducted by 

 the author in confirmation of, or refuting, the views of others, and 

 the various theories are summarised in careful fashion, so that we 

 possess in these pages a valuable historical account of the investiga- 

 tions made and suggestions advanced by the chief workers and 

 thinkers of all ages and nationalities. The senses of vision, smell, 

 taste, hearing, and touch, as well as the instincts of direction and 

 orientation in space, the faculty of communication, memory, and 

 judgment, all have their place. Altogether this is a delightful and 

 most instructive volume, which at such a moderate price should be 

 in the possession of all thinking naturalists who aspire to something 

 more than the mere collecting and naming of specimens. 



British Butterflies. Vol. ii. By J. W. Tutt, F.E.S. 

 London, Eliot Stock. Price 21s. net. 



The entomological reader must now be quite familiar with the 

 maroon masterpieces which are following one another in rapid succes- 

 sion, and which go to form the most complete account of British 

 Lepidoptera that has ever been published. It is almost superfluous 

 on our part to recommend the closely-printed volume of nearly 500 

 pages which has recently been completed. Suffice it to say that to all 

 appearance the work is as thoroughly done as ever, the seven species 

 dealt with as in Part ii., occupying, with the accounts of the groups 

 to which they belong, over 400 pages. The first part of this im- 

 portant work is devoted to a most welcome account of the habits of 

 butterfly larvae. This section of the volume will be read by 

 entomologists with the most intense interest. It is thoroughly 

 up-to-date, and contains the observations of practically all the 

 best-known investigators in Britain, the continent of Europe, and 

 North America. The work is embellished with twenty-seven plates, 

 which are chiefly micro-photographs of various larval and pupal 

 structures.
