OUR COMMON INSECTS, 



By the author of The Guide to the Study of Insects. 



This little volume by Dr. Packard will be issued by the Naturalists' Agency early in 

 the coming autumn, and will contain a popular account of the more common insects of 

 our country, embracing chapters on 



BEES, BUTTERFLIES, MOTHS, FLIES, MOSQUITOES, 

 BEETLES, ETC., ETC., 



while a Calendar will give a general account of the more common injurious and benefi- 

 cial insects, and their time of appearance, habits, etc. 



The volume will be a 12mo of upwards of 200 pages, profusely illustrated by Wood 

 Cuts, and is intended for the general reader, and the young student, thereby tilling a 

 gap in the entomological literature of this country, while the low price of $2.50 will 

 bring it within the reach of all. Send orders to
