224 THE CANADIAN ENTOMOLOGIST. 



there are very few, even among entomologists, who will read the 

 book from cover to cover ; only such lepidopterists as are more or less 

 familiar with the butterfly fauna of the entire world will find all of its 

 chapters readable. 



Dr. Longstaff's travels have taken him to India, Ceylon, China, 

 Japan, Algeria, Egypt and the Soudan, South Africa, the West Indies, 

 South America, Canada, Australia and New Zealand ; so that he has 

 enjoyed the somewhat unusual experience of having collected butterflies 

 in every continent of the globe. His sojourn in Canada was limited 

 to a rapid journey across the continent in 1904 on his return to 

 England from the Orient and very little opportunity for collecting was 

 had on the way, but in tropical countries Dr. Longstaff's experience 

 has been wide and varied and he shows himself to be thoroughly 

 famihar with butterfly life everywhere. 



Many amusing anecdotes and interesting impressions of the various 

 countries visited by the author, and of the customs of their nihabitants, 

 are scattered through the volume, greatly helping to enliven it ; while 

 all that is of real scientific value is encompassed in the last chapter, 

 entitled *'Bionomic Notes". This chapter contains many interesting 

 notes under the following headings : "The scents of butterflies"; "The 

 coloured juice exuded by certain Lepidoptera"; "The tenacity of life 

 of protected species"; "Butterflies bearing marks of the attacks of 

 foes"; "Experimental evidence as to the palatability of butterflies"; 

 "Mimics in the field deceiving man"; "Notes on the flight of sundry 

 butterflies"; " Heliotropism"; " List and shadow" ; " The inverted 

 rest attitudes of Lycaenids and some other butterflies"; "General 

 remarks on rest attitude of butterflies"; "Cosmopolitan Lepidoptera"; 

 "Seasonal dimorphism"; "The selection as resting-places of yellow 

 leaves by yellow butterflies". 



As a supplement translations by Ernest A. Elliott, F. Z. S., 

 F. E. S., of a series of important papers by the late Fritz MûUer 

 on the scent-organs of Lepidoptera have been appended to the book, 

 together with an introductory note by Prof. E. B. Poulton, by whose 

 suggestion they were included. 



The book, including the appendix and the very full index occupies 

 728 pages. It is illustrated by six good coloured plates, upon which many 

 other insects besides butterflies are depicted, and 19 text figures. The 

 appendix is also illustrated by nine lithographic plates.
