VI PREFACE 



Geographic distribution is indicated by listing the names of all coun- 

 tries from which the species has been recorded. A question mark before 

 a country name indicates that the record is probably erroneous. Two 

 country names both preceded by question marks indicate doubt as to which 

 is the proper locality. A question mark alone indicates that no locality 

 record has been found by the compiler but that the species probably is 

 from our region. If a general term such as South America is given, no 

 more specific locality was found or else the locality could not be identified 

 on available maps. Distribution outside of Latin America is indicated 

 by one or two additional localities, as U. S. A. or Old World (or Hawaii, 

 Australia, or Africa). Island records are listed separately, often with a 

 footnote reference to theu- location (geographically, not politically). All 

 these locality records are listed in a fixed order starting in the north and 

 proceeding southward and eastward. First Baja California and the rest 

 of Mexico (with neighboring islands), then thi'ough Central America and 

 South America lo Chile and neighboring islands, and finally the West 

 Indies from the Bahamas and Cuba to Grenada. If there are only West 

 Indian and South American records, the West Indian ones come first and 

 aU follow from north to south as before.
