4 GENERAL CATALOGUE OF THE HOMOPTERA 



In this part of the catalogue a method of literature citation has 

 been adopted which differs from that used in the catalogues of the 

 fulgoroid families. References are cited by author, year, and key 

 letter, e.g., Fabricius 1802a. The full reference can be obtained by 

 consulting the Bibliography of the Cicadelloidea, in which authors are 

 arranged alphabetically, and their works chronologically under the 

 author's name. This method of citation eliminates the necessity for 

 a complete literature citation in the catalogue proper, and thus saves 

 time, space, and publication costs. It is believed that the revised 

 method will cause no great inconvenience to the reader. Dr. Metcalf 

 himself advocated it under certain conditions, and it is felt that he 

 would have approved its use for his catalogues. 



The Family Eurymelidae consists of 24 genera and 82 species. 

 The following family characters have been compiled from Evans 

 1946b: 48-53. Head with face flattened, usually wider than long; 

 transclypeal suture entire; postclypeus, often delimited dorsally by 

 sutures; ocelli on face. Hind tibiae often with small spines, each 

 with a subapical seta. Male with ninth sternum not occurring as a 

 distinct sclerite; aedeagus not articulated with connective. Food 

 plants, trees (often Eucalyptus), or plants associated with trees. 

 Adults and nymphs gregarious and attended by ants. 



The following classification has been adopted for this family:

Subfamily Eurymelinae ._ 7 



Subfamily Ipoinae 28 



Subfamily Pogonoscopinae 39 



The species in this family are confined to the Austrahan and 

 Austromalayan Regions. The known geographic distribution of each 

 species is indicated by superscript figures at the end of the lines, 

 which correspond to geographic regions designated by the same super- 

 script figures. In general, the distribution is as given by the author 

 of the reference, the country being considered the smallest unit ex- 

 cept in the case of large countries where states and provinces are the 

 smallest units. In the larger island groups the individual islands are 

 indicated wherever possible in view of the importance of island 

 endemism.
