For the purposes of this index subgenera and varieties are treated as genera and species, but the 

 species of any genus will usually be found assembled under the generic and not the subgeneric name. 

 Names of groups and species first published in this work are in italics. The page number indicating 

 the place where a diagnosis or synonymy is given, or where important information is to be found, is in 

 italics ; a single reference or casual mention is indicated by Roman numerals.
