4 GENERAL CATALOGUE OF THE HOMOPTERA 



Bibliogra'phy of the Cicadelloidea, in which authors are arranged 

 alphabetically, and their works chronologically under the author's 

 name. This method 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 Hecalidae consists of thirty-one genera, two subgenera, 

 and one nomen nudum genus, with 167 species. The leafhoppers in- 

 cluded in this group are small to medium in size and are often dorso- 

 ventrally flattened. They are usually brown or green, or green marked 

 with orange. The lateral clypeal sutures do not extend dorsad beyond 

 the antennal pits. Antennal ledges are vestigial or absent. The mar- 

 gins of the genae are usually sinuate. The ocelli are located on the 

 anterolateral margins of the head or on the crown near the margins. 

 The lateral margins of the pronotum are usually carinate. Sexual 

 dimorphism is of common occurrence. The food plants are most often 

 grasses, but species have been reported to feed on rushes, Casuarina, 

 and Melaleuca. 



The following classification has been adopted for this family :

Tribe Eupelicini 67

Tribe Paradorydiini 104 



The species have been recorded from the following zoogeographical 

 regions : 39 from the Nearctic Region, 2 from the Caribbean Region, 

 8 from the Neotropical Region, 39 from the Palearctic Region, 35 from 

 the Ethiopian Region, 18 from the Oriental Region, 9 from the Ma- 

 laysian Region, 15 from the Australian Region, and 2 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 miit, 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.
