On the species of OODES and allied genera of the United States. 

 BY GEO. II. HORN. M. D. 



The description of our ^species of the genera allied to Oodes are so 

 widely scattered as to make reference to them in many instances diffi- 

 cult, while the descriptions of Chaudoir are inaccessible except to 

 those having access to the large scientific libraries, and at the sugges- 

 tion of several correspondents, this and the two preceding papers have 

 been prepared.
