4 GENERAL CATALOGUE OF THE HOMOPTERA 



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

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

 consulting the Bibliogra'phy 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 of literature citation 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 catalogue. 



The Family lassidae consists of 47 genera and 317 species. Family 

 characters are not listed here because the leafhoppers presently as- 

 signed to this group are so varied. 



The following classification has been adopted for this family :

Family lassidae 5 



Subfamily lassinae , 19 



Tribe lassini 20 



Tl'ibe Troenadini 133 



Tribe Reuteriellini 134 



Tribe Selenoeephalini 136 



Tribe Krisnini 193 



Tribe Platyjassini 208 



The species have been recorded from the following zoogeographical 

 regions : 20 from the Nearctic Region, 6 from the Caribbean Region, 

 25 from the Neotropical Region, 70 from the Falearctic Region, 65 

 from the Ethiopian Region, 34 from the Oriental Region, 34 from the 

 Malaysian Region, 9 from the Austromalayan Region, 25 from the 

 Australian Region, 15 from the Oceanic Region, 13 from two or more 

 regions, and 1 from an unknown locality. 



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 gen- 

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

 country being considered the smallest unit, except in the case of large 

 countries, where states and provinces are the smallest imits. In the 

 larger island groups the individual islands are indicated wherever 

 possible in view of the importance of island endemism.
