Type, T. viridis, Linn. 



The type of Stal's subgen. Amblyscarta is A. modesta, Fabr., 

 and taking that species asastandard, Ambhjscartashould rank 

 as a distinct genus. But the mutations between modesta, 

 Fabr., and viridis, Linn., the type of TettiqonieUa, are so 

 gradual that no actual generic demarcation can be made 

 between them. As regards the subgen. Po?ciloscarta, Stal, 

 the type of which is cardinalis, Fabr., the distinction is less, 

 while some of the species included by Stal in that subgenus 

 belong to Kolla, Dist. It therefore seems best to follow 

 Stal with the two above subgeuera_, though others may be 

 recognised as of generic value.
