PERIODICAL LITERATURE 167 



field ?" But an hour spent in reading this new book by Miss 

 Dickerson, of the Rhode Island Normal School, convinces that it 

 fills an unoccupied place in the popular literature on these most 

 popular insects. Here we have in a book of convenient size more 

 of the kind of information wanted by the average beginning stu- 

 dent than can be found in any other two volumes. We have other 

 good books on common butterflies, e. g., Comstock's " How to 

 Know the Butterflies," Scudder's " Everyday Butterflies," and 

 Holland's " Butterfly Book," and on moths we have Holland's 

 •' Moth Book " and Eliot and Soule's " Caterpillars and their 

 Moths " ; but no recent volume including both types of the lepi- 

 dopterans. Ballard's " Moths and Butterflies " has for many 

 vears been popular, but in illustrations and contained information 

 it does not meet the needs of readers who are attracted to books 

 like those named above. Dickerson's " Moths and Butterflies " 

 has many of the characteristics which have made the books by 

 Comstock, Scudder and Holland popular, and for the average be- 

 ginning student of these insects the book may take the place of any 

 two volumes named above, because it gives special attention to 

 about a dozen butterflies and as many moths which are most com- 

 mon, and therefore best for beginning study. The two hundred 

 photographs from life make it possible to identify caterpillar, 

 chrysalis or cocoon, and the adult stage. The book closes with a 

 very practical chapter on how to collect, keep, and study butterflies 

 and moths. This will be especially useful to teachers of nature- 

 study in September and October.
