From the figures presented above, the most striking fact that will be ap- 

 parent is not the number of species found in any one region, but the meagre 

 information that we have concerning the Cicadellid fauna of the majority of 

 the states and provinces. The value of state and even local lists is here quite 

 apparent, through the service that they render in extending the known dis- 

 tribution of species. 



It is quite evident that certain sections accommodate a considerably larger 

 number of species of Cicadellidae than others whose climatic conditions are less 

 varied, but it may be estimated that nearly all of the states should give from 

 150 to over 250 species. Considering the meagre collecting that appears to 

 have been done in certain parts of our territory the total number of living 

 species of this group will undoubtedly be found to be greatly in excess of one 

 thousand.
