4 GENERAL CATALOGUE OF THE HOMOPTERA 



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

 letter, e.g., Fabricius 1803a. The full reference can be obtained 

 by consulting the Bibliography 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 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 Tettigellidae consists of 169 genera, 10 subgenera, 14 

 invalid genera, and 1,446 species. This family may be characterized 

 as follows: Head with ocelli located on crown, usually closer to hind 

 margin than to apex; lateral clypeal sulci usually extending dorsally 

 onto crown of head; transclypeal sulcus usually interrupted medially; 

 clypeus and clypellus tumid. Pronotum nearly always with a lateral 

 carina on each side between dorsinn and pleura. Forewing with 

 two claval veins; appendix nearly always present; inner apical vein 

 parallel to long axis of wing; basal portion of wing usually thicker 

 than an apical membranous area, which is of variable extent. 



The following classification has been adopted for this family:
