THE following work is intended as a companion to the " List 

 of the Coleoptera of North America," by Dr. LeConte, It 

 contains the descriptions of the new species named by him in 

 Part I of the " List," which embraces the families treated of in 

 Part I of the Classification of the Coleoptera of North America. 



The three works having been thus brought to the same point, 

 it is the intention of Dr. LeConte to complete the series as soon 

 as practicable.
