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

 have approved its use for his catalogues. 



Under the system used here, and to be used for subsequent portions 

 of the Cicadelloidea catalogue, the literature references are cited by 

 author, year, and key letter, e.g. Fabricius 1802a. The full reference 

 can be obtained by consulting the Bihliography of the Cicadelloidea 

 in which authors are arranged alphabetically, and their works chrono- 

 logically under the author's name. This method of citation eliminates 

 the necessity for a complete literature citation in the catalogue proper. 



The Family Hylicidae consists of fourteen genera and twenty-eight 

 species. In the following summary of family characters, Evans' work 

 (Roy. Ent. Soc, London, Trans. 97(2) : 39-54, 1946) has been very 

 helpful : 



Head well produced ; transclypeal suture distinct ; ocelli on crown. 

 Pronotum wider than head including eyes; proepisterna at least 

 partially concealed by head. Forewings elongate, with a very broad 

 appendix extending completely around wing apex ; posterior margin 

 of clavus broadly convex, not angulate. Body and wings with sparse 

 setae and scales. 



Ross (Syst. Zool. 6: 87-98, 1957) has stated that the hylicids have 

 three macrosetae near the apex of the hind femur, and that the hind 

 tibiae have a row of large spines, each of which has a "hair" set in it. 



One of the species in the present catalogue has a distribution cover- 

 ing two or more zoogeographic regions. The other species are re- 

 corded as follows: eight from the Oriental Region, seven from the 

 Palearctic Region, seven from the Ethiopian Region, and five from the 

 Malaysian Region. 



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 the smallest unit, except in the case of larger 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.
