Division TROPICORAIUA. 



In this and the succeeding divisions of the Pentatominae the 

 abdomen is more or less distinctly sjiined at the base, the spine 

 being sometimes long, whilst in other genera the protuberance is 

 more of an angulated tubercle. In the Tropicoraria as here de- 

 fined the pronotal lateral margins are dentate or serrate, sometimes 

 crenulate, but never entire. The pronotal angles are always, 

 usually strongly, produced.
