Brief Guide to the Commoner Butterflies of the Northern 

 United States and Canada. Being and introduction to a knowledge 

 of their life-histories. By Samuel Hubbard Scudder. Published by Henry 

 Holt & Co., New York; lamo., 206 pp. — The book begins with a chapter 

 entitled, " What are Butterflies?" and is followed by others on structure, 

 etc., of the imago, egg, caterpillar and chrysalis, the lives and habits of 

 caterpillars, how the chrysalis hangs, variation, etc., sexual differences, 

 senses, mimicry and protection, classification of butterflies, followed by 

 an interesting and valuable chapter describing some of the more important 

 works on American butterflies. Next follow keys to the various groups 

 based on the perfect butterfly, the caterpillar and chrysalis. The body 

 of the work is made up of the descriptions of the imago, egg, caterpillar 

 and chrysalis, etc., of the species treated. The work ends with an ap- 

 pendix of instructions for collecting, rearing, preserving and studying, 

 and the whole makes a work that no beginner can well get along without.
