field naturalist, and contains elaborate keys for the identification of 

 both sexes, as well as such nymphs as are known to science, of the 

 sixteen North American species of the genus ; one of these being 

 also found in Britain. There are also fifty-six pages devoted to the 

 biology and bionomics of the group. 



" The remarkable Life-historj^ of a new family [Micnniwlthidir) 

 of Beetles," by Herbert S. Barber, Bureau of Entomology, 

 Washington, D.C., a paper which appeared in the Proceedings of 

 the Biological Society of Washington, Vol. xxvi, contains a further 

 account of the life-history of a North American beetle, Mirronialthiis 

 ■debUis, Lee, and the facts already brought to light are more than 

 sufficient to justify the claim that the life-history of this beetle is 

 -" the most remarkable in the Coleoptera if not one of the most 

 remarkable in the whole Class Insecta." Mr. Barber hopes to give 

 .a complete account of the life-history later. 



" The Theory of Evolution in the light of facts," by Karl Frank, 

 :S.J., with a chapter on Ant Guests and Termite Guests by Erich 

 Wasmann, S.J. Translated from the German by T. Druery, F.L.S., 

 attempts to show the limitations of Evolution by arguments based 

 chiefly upon the imperfection of the palteontological record. The 

 chapter by Father Wasmann is very interesting, and contains a 

 table of interest to Coleopterists, illustrating the pedigree of the 

 beetles and their distribution in time. 



" The Life of the Fly," by J. Henri Fabre, another of this 

 ^talented author's popular volumes, made its appearance daring the 

 .past year. Interspersed among other matter are some chapters of 

 autobiography which will enable such as desire to do so to know 

 more of the writer, Avhose avowed object is to make the younger 

 generation love natural history ; and it would be hard to name a 

 happier mentor, for such as make their investigations under 

 M. Fabre's guidance. 



"British Butterflies," by A. M. Stewart (Peeps at Nature Series), 

 with really excellent coloured plates illustrating by the three colour 

 process practically every British butterfly on a slightly reduced 

 scale, can be confidently recommended to the incipient lepidopterist 

 as a very useful introduction to knowledge of the subject. 



" The Coleoptera of the British Islands," by W. W. Fowler, 

 M.A., D.Sc, F.L.S., and Horace St. John Donisthorpe, F.E.S., 

 Vol. vi., Supplement, collates, amplifies and brings together the 

 -enormous amount of new matter which has been published from 

 time to time since the issue of the original five volumes in 

 1887 and 1891, bringing it right up-to-date. Mr. Donisthorpe's
