FIELD BOOK OF INSECTS. 



In closing, permit me to request that, if errors are de- 

 tected among the thousands of categorical statements 

 made in this book, they be brought to my attention. If 

 portions are not clear or if you desire further information, 

 I shall be glad to do what I can to help you. It is for such 

 a service, among others, that the American Museum of 

 Natural History, New York City, exists.
