BULLETIN IS 5, UNITED STATES N'ATTONA.L MUSEUM 



reported from America south of the United States of America up to 1941 

 (and sonie times to 1943), 



This list is offered frankly as a preliminary checklist. It is known to 

 contain many inaccuracies and inconsistencies. The production of a 

 highly accurate list at this time would have required many times longer 

 and could not be justified under the circumstances. The present list 

 will be considered by the compiler to have served its purpose if it spurs 

 the publication of numerous additions and corrections, accentuates the 

 need for revisionary studies on many genera and families, and leads to the 

 pubhcation of more complete and useful checklists in the future. That 

 it will be useful is proved by the use ah-eady made at the United States 

 National Museum of the manuscript while in preparation, but it should 

 be treated as a stepping stone to speed the accumulation and integration 

 of the data that are much needed by entomologists in these regions. 



Although the present checklist is based in part upon the Coleopterorum 

 Catalogus of Junk and Schenkling, which is a bibliographic catalog of the 

 Coleoptera of the World, and is expected to be used in conjunction with 

 the'Leng Catalog of Coleoptera of America North of Mexico, the compiler 

 has"not found it advisable to follow the arrangement of families employed 

 in either of these works. In the second supplement to the Leng Catalog 

 Mr. Long made it clear that he approved of the changes in his classifi- 

 cation that were suggested by Boving and Craighead in their Synopsis of 

 Larval Coleoptera in 1931. These were again substantiated by Peyerim- 

 hoff in 1933. Except for certain changes suggested in more recent studies, 

 the classification given by Peyerimhoff has been used herein, as follows:
