This communication concludes my efforts to revise and 

 systematize the genera of the family Cicadida?. There are a 

 few genera with which I am still unacquainted — Nosola, 

 Stal, Nahlistes, Karsch, PlautUla, Stal, Paectira, Karsch, 

 and Tn'glena, Fieb., — but these will, I hope, be located in a 

 subsequent synonymical catalogue of the family.

 body, sometimes scarcely longer than the abdomen ; abdomen 

 usually inflated, always thickened.
