The tribe is a large one. being represented in the United States 

 fauna by 17 genera. 14 of which occur in Indiana, ^lany of these 

 have been established on ti'ivial or sexual characters, so that they 

 are difficult to distinguish ludes'^- both sexes are at hand. To uuike 

 shorter an otherwise lon.g generic key, the genera are distributed by 

 Tier!! among four subtribes. thre(> of which are represented in 

 Indiaiui.
