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

 than the basal segment of the antennas. 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 rf is 

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