 kinds in abundance. 



I can recommend this method of collecting to anyone interested 

 in the Plusiidce; the moths come freely, preferring sunflowers to 

 any other kind of flower that I have grown for this purpose, they 

 they are easily taken, and with a minimum of rubbing. Moreover, 

 the seed is cheap and the plants very easily grown anywhere.

The Life Story of Insects. By Prof. G. H. Carpenter (Cam- 

 bridge Manuals of Science and Literature), 134 pp., 23 figs. 

 Cambridge University Press. Price, one shilling. 

 Notwithstanding the existence of numerous entomological 

 books of an elementary character, the treatment of the subject in 

 the present little volume makes it peculiarly suitable to place in the 

 hands of a person having no knowledge of insect life. It does not 

 attempt to accomplish more than "an outline sketch of the facts 

 and meaning of insect transformations," and, in the modest words

 reading should lead fresh observers to the brookside and woodland." 

 We feel that its object will frequently be served, for it cannot fail to

 life in its varied forms and it is sure to be the means of directing 

 many a wayfarer's steps into the fascinating paths of entomological 

 enquiry. 



After describing the form and growth of insects, the life-his- 

 tories of certain sucking insects, such as the aphids, are given. 

 The author then passes on to a consideration of the adaptations and 

 transformations of aquatic insects. This leads him to a discussion 

 of the internal changes which accompany metamorphosis. A most 

 readable account of the different larval forms and their adaptations 

 constitutes the longest chapter in the book and the well-chosen 

 illustrations contribute greatly to its clearness. A consideration of 

 the varied pupal forms and their modifications naturally follows. 

 A chapter on the life-story of insects in relation to the seasons 

 succinctly portrays the varied life-cycles in relation to the seasons 

 of the year and to seasonal conditions. The book concludes with 

 an interesting chapter on the past history of insect life. In this the
