Characters. — Here the pronotum has the lateral carina? more or less acute. The fastigium ot 

 the vertex is noticably broader than the basal segment of the antennae. The organs of flight are short, 

 often lobiform and, in female especially, wholly concealed beneath the posteriorly produced pronotum. 

 Ovipositor usually distinctly decurved apically.

Characters. — The members of this genus has the fastigium of the vertex scarcely broader 

 than the basal segment of the antennae. The organs of flight are fully developed but in some species 

 they are much longer than in others. The ovipositor is usually long and generally curved more or less 

 distinctly downwards. They are rather large green insects and the tympanum of the elytra in the (f is 

 large and well developed. The hind tarsus often has a distinct plantula. (Plate I, Fig. 9.)
