4 GENERAL CATALOGUE OF THE HOMOPTERA 



author's name. This method eHminates the necessity for a complete 

 hteratiire 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 Macropsidae consists of 11 genera and 183 species. 

 This family may be characterized as follows : Length usually 4-8 mm. 

 Wedge-shaped leafhoppers. Head and thorax usually punctate, 

 occasionally rugose. Head with crown short; ocelli located on face 

 or rarely on anterior margin of head; antennal ledges prominent; 

 transclypeal suture indistinct or absent; lateral clypeal sutures not 

 extending dorsad beyond bases of antennae. Pronotum with lateral 

 margins usually not carinate. Metanotum with median suture 

 present or absent; hind femoral setal formula 2:1:0. Male genitalia 

 with plates long and slender; styles usually long and slender and with- 

 out anteapical lobes; connective often with a median anterior lobe. 

 Species very often host-specific, most often on trees, occasionally on 

 herbs. 



The following classification has been adopted for this family:

Subfamily Macropsinae 7 



Tribe Macropsini 7 



Tribe Nioniini 246 



The species have been recorded from the following zoogeographical 

 regions : 43 from the Nearctic Region, 6 from the Neotropical Region, 

 54 from the Palearctic Region, 17 from the Ethiopian Region, 5 

 from the Oriental Region, 12 from the Malaysian Region, 39 from 

 the Australian Region, and 7 from two or more regions. 



The known geographic distribution of each species is indicated by 

 superscript figures at the end of the lines, which correspond to geo- 

 graphic regions designated by the same superscript figures. In 

 general, the distribution is as given by the author of the reference, 

 the country being the smallest unit, except in the case of large coun- 

 tries, 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.
