/. All of the femora sulcate below and arined on the external 



margin with some small spines; anterior and middle tibiae 



sulcate above and, with the exception of the apical spine, 



smooth or i)rovided with only a few spinules. 



g. Middle tibire noticeably compressed and dilated at base; 



the hind margin of the disc of the pronotum rounded. 



Uberaha, gen. nov., Bruner. 



gg. Middle tibia; of usual form, not especially compressed and 



dilated at base; hind margin of the disc of the pronotum 



truncate. [Ecuador] Polychnodes Giglio-Tos. 



//. All of the femora non-sulcate below, the anterior and middle 

 pairs armed on the lateral margins with series of long and 

 slightly curved spines; anterior and middle tibiae rounded 

 above, their lower margins also lengthily spined. [Costa 



Rica] Alogopteron Rehn. 



ee. Ovipositor not abnormally short, usually as long as, or longer than, 

 the pronotum, its margins towards the apex crenulate or serru- 

 late, very rarely smooth. Subgenital plate of cf with or with- 

 out free styles. 

 /. Anterior tibiae on their inner margin with the auditory for- 

 amina shell-like or sublinear, externally typically wide open. 

 Ovipositor broad, its apical half convex and covered with 

 flattened squamiform, imbricated tubercles, the edges of 



which are directed forwards Ccelophyllum Scudder. 



ff. Anterior tibiae with one or two exceptions having the auditory 

 foramina on both sides either wide open, or narrow and 

 shell-like. 

 * Anterior and middle tibiae sulcate above, or plain, but acute-angled, on the 

 outer margin either spined or smooth. 

 b. Fastigium of the vertex somewhat depressed, acuminate or truncate. 



c. Anterior and middle tibiae, with the exception of the external apical spine, 

 unarmed above. Tegmina narrow, their apex rounded, the radial 

 veins separated at the base. All the femora unarmed beneath. 



Wings much longer than the elytra Phaneroptera Serville. 



cc. Anterior, or at least the median, tibiae spined above. Tegmina, wings, 



and femora variable. 



d. Pronotum strongly saddle-shaped, the disc elevated posteriorly. 



Tegmina with their hind margin sinuate and the apex either 



obliquely truncate, or rounded. Auditory openings on both sides 



of the anterior tibiae linear [Venezuela] Sictima Walker. 



dd. Pronotum with the disc either plain or saddle-shaped, but not 



elevated either in front or behind. Tegmina with their posterior 



margin straight or sinuate. Posterior femora beneath spined or 



lobate. The auditory foramina wide open. 



e. Tegmina narrower (except in Dolichocercus), their posterior 



margins sinuate. The anterior femora above often compressed 



at their apex, acuminate. Posterior femora with their genicular 



lobes lengthily acuminate.
