observations on the habits of caterpillars and adults by the authors. 

 Synonomy is complete and for each species there are page references 

 to other works in which it is described or illustrated. The keys to 

 families, genera and species make use of non-technical characters — 

 wing shape, color and pattern, size — as far as possible so that in 

 only a few cases is it necessary to consider the venation of the wings 

 or to use a lens for minute characters. Unfortunately after deter- 

 mining a specimen by use of the keys no page references are found, 

 but one must either hunt through the following pages or turn to the 

 index to find the location of the descriptions. 



The book begins with brief accounts of butterflies in folklore, 

 curious facts about butterflies, protective coloration and mimicry, 

 sense organs, hibernation and migration, habitats and ranges, classi- 

 fication and the use of the keys. Half a dozen pages are used in 

 explaining in detail how to collect, kill and mount specimens, with 

 suggestions as to making nets, killing jars and display cases. 



Twenty-eight butterflies are beautifully illustrated in the four 

 color plates and there are photographs of thirty-eight others — but 

 again the lack of page references in the descriptions makes the 

 locating of the illustrations a matter of search. The book is bound 

 in green cloth and the press work leaves nothing to be desired. 



Both of the authors have been collecting and observing butter- 

 flies for twenty-five years or more and each has published numer- 

 ous technical papers and popular articles. Dr. Shepard is Assistant 

 Professor of Entomology at the University of Minnesota ; Dr. Macy, 

 Professor of Biology at the College of St. Thomas at St. Paul, 



Minnesota. „ _ ^^
