Introduction 3 



discovered by other workers on this extremely interesting but little known 

 family. Many species of Membracidae have never been recognized since 

 their original description and the types are not available. Some of these 

 may never be recognized because of poor descriptions, some are doubtless 

 synonyms, some have probably been described under other names, but all 

 must be here included until more extensive work has been done on the 

 family. We can only hope that we have not omitted species nor many of the 

 more important references. Since the genera are arranged alphabetically, 

 we are giving below a systematic arrangement of the family which rep- 

 resents the natural sequence of the groups as well as we can determine it 

 at present.
