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 catalogue. 



The Family Agalliidae consists of 30 genera, 4 subgenera, and 312 

 species. Family characters are not listed here because the leafhoppers 

 presently assigned to this group are so varied. 



The following classification has been adopted for this family:

Family Agalliidae 1 



Subfamily Agalliinae 3 



Subfamily Austroagalloidinae 159 



Subfamily Melicharellinae 161 



Subfamily Adelungiinae . 171 



The species have been recorded from the following zoogeographical 

 regions: 72 from the Nearctic Region, 34 from the Caribbean Region, 

 76 from the Neotropical Region, 70 from the Palearctic Region, 19 

 from the Ethiopian Region, 15 from the Oriental Region, 1 from the 

 Austromalayan Region, 9 from the Australian Region, 1 from the 

 Oceanic Region, and 15 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 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 units. In the 

 larger island groups, the individual islands are indicated wherever 

 possible in view of the importance of island endemism.
