d. Anterior tibiae above closely armed on their hind margin with strong

roundly or angulately joined. 



e. Pronotum with its lateral lobes roundly inserted. Hind femora

ee. Pronotum with its lateral lobes joined to the disc by an acute or 

 obtuse angle. Hind femora unarmed beneath. 

 /. Wings rudimentary or wanting. Pronotum provided with 

 well-defined lateral carinae. Tegmina as long as the abdo- 

 men, acuminate, the median veins widely separated. 



Euxenica, gen. ncv., Bruner. 



ff. Wings present and fully developed, slightly or even greatly 



longer than the tegmina. 



g. Wings more than one-half longer than the tegmina. The 



latter attenuated apically. Ovipositor narrow, nearly 



straight, its disc roughened and with its margins acutely 



serrato-dentate Burgilis Stal. 



gg. Wings scarcely one-third or only a trifle longer than the 



tegmina. Ovipositor strongly curved, compressed, 



either smooth or rugulose, its margins obtusely serrate. 



h. Tegmina strongly dilated at their base, their anterior 



margin broadly rounded, apex acuminate, the 



tympanal field not unusually dilated. Wings a 



little longer than the tegmina. Ovipositor semi- 



circularly curved, its disc somewhat roughened. 



Coryplioda Brunner. 

 hh. Tegmina narrow, their apex rounded, and with the 

 tympanal field normal. Wings one-fourth longer 

 than the tegmina. Ovipositor strongly compressed, 

 short, suddenly bent or curved upward at thfe base, 

 its disc smooth. 

 i. Tegmina with the cross-veins in the marginal and 

 radial fields parallel, close together; radial vein 

 beyond the base contiguous. . . .Aniarella Bolivar. 

 it. Tegmina with the cross-veins irregular; radial veins 

 separated from the base to their outer extremity.
