PREFACE 



The organization of a corps of voluntary observers makes it necessary 

 to issue directions for collecting and shipping insects. It is believed that 

 the chapter on the distribution of insects will be a valuable guide in 

 directing observations along lines hitherto largely ignored. This bul- 

 letin has also in view the guidance of pupils who, for a small compensa- 

 tion, may undertake to collect insects for the state. It was thought 

 best to include directions for preserving insects, in order to encourage 

 younger students to build up collections of their own. 



No claim is laid to originality in the text of this bulletin, as available 

 sources of information have been freely consulted. The illustrations are 

 all original, having been prepared under my direction by my assistant, 

 Mr C. S. Banks.
