THE AMERICAN MUSEUM OF NATURAL HISTORY 



Following is a series of exhibits concerned with the life 

 histories of insects, their relation to vegetation, their ene- 

 mies and the means used by man to combat the injurious 

 species. 



In other sections of the hall are exhibits of silkworms, 

 honey bees, seventeen-year cicada, mound-building ants, a 

 group of monarch butterflies as they are found during their 

 migratory period in early autumn, and a revolving; case 

 showing the iridescence of opaque insects. 



The general study collection 15 is not on exhibition but 

 may be seen on the Fifth Floor by visitors desiring to make 

 a more extended study of insect life.
