NOTE. 



The second part of this work will contain those families embraced in 

 the divisions Tetramera and Trimera of the older authors ; in them, the 

 penultimate joint of the tarsi is closely connate with the last joint, and 

 forms merely an enlargement at the base of it. 



I am now preparing a synonymical list of the species of Coleoptera of 

 America north of Mexico. For the purpose of rendering the work as com- 

 plete as possible, it is very desirable that increased collections should be 

 made in the western portions of the Continent, especially in Texas, New 

 Mexico, and the regions west of the Rocky Mountains. I would therefore 

 appeal to those who may be willing to make collections within the regions 

 mentioned, to aid me in this work. Due credit shall be given in my pub- 

 lications for the assistance received, and, when desired, the duplicates, 

 properly named, shall be returned to the persons collecting.
