PART 2.— BIOLOGY. 



INTRODUCTION. 



The second portion of this Bulletin consisting of Biological Notes 

 is b}^ the junior author, and is devoted to a discussion of the habits 

 of Nearctic termites. In the past, due to a much needed taxonomic 

 revision, such a discussion has not been possible. There has not only 

 been much confusion as to the identity of species, but also the litera- 

 ture often attributes habits to Nearctic termites which are possessed 

 by tropical species alone. One can not thus generalize even when 

 dealing with the species of one continent. This is just as flagrant an 

 error as the references to the nightingale as a native bird in American 

 poetry of the Colonial Period. 



As in case of Part 1 on taxonomy, our knowledge is as yet very 

 incomplete, and often merely fragmentary. It is hoped that this 

 work will pave the way for a complete monograph. The complex 

 biology of termites offers an intensely interesting field of study. 



The character and extent of damage, by Nearctic termites, with 

 methods of preventing and remedying such damage, are outlined.
