NOTES, REVIEWS, AND COMMENTS. 



Entomology. *Frail Children of the Air. Another 



of Mr. Scudder's delightful books has just come to hand, with the above 



pretty title. It is a tastefully bound 8vo. of 279 pages, containing 31 



short chapters, 9 plates, on the habits and structure of butterflies, 



written in a graceful, but clear and popular, style, which will make the 



book entertaining to many who have never taken any special interest 



in butterflies and will, we believe, realise the author's hope, expressed in 



the preface, "gain for our butterflies a deeper interest and closer 



attention on the part of the observing public". This is really an 



excellent selection from a series of papers which ran through Mr. 



Scudder's large and costly work, " The Butterflies of. the Eastern 



United States and Canada," and, although forming a "consistent 



whole," each chapter is complete in itself. The following titles of 



some of the subjects treated will give a slight idea of the scope of this 



attractive little volume: Butterflies in Disguise, Butterflies as Botanists, 



Butterfly Sounds, The Eggs of Butterflies, How Butterflies pass the 



Winter, Protective Colouring in Caterpillars, The Procession of the 



Seasons, Some Singular Things About Caterpillars, The Friends and 



Associates of Caterpillars, Butterflies of the Past.
