THE CANADIAN ENTOMOLOGIST 117 



The Cicadellidae is represented in America north of Mexico, by 70 genera 

 through which are distributed some 773 species now held to be distinct. On 

 the whole, very little has been done to determine the fauna of any given locality. 

 Several lists, however, have been published and for at least six states the family 

 has been collected extensively and recorded. There may be mentioned the 

 New York and Maine lists by Prof. Osborn, the Tennessee list by De Long, 

 the Wisconsin list by Saunders and De. Long, the Missouri list by Gibson and 

 Cogan, and the South Carolina list of Lathrop. In addition to these more 

 extensive lists there have been several minor lists, which need not be mentioned 

 here. 



Of the 773 recognized species, some 294 have been recorded from but one 

 locality, the locality of the type and apparently never recovered. The localities 

 of these follow: 



"Am. Sept." 1 Tenn 19
