Caput subglobosum, anterius planatum; rostro verticis latiuscule rotundato, trigonali-excavato, scrobiculis 

 antennarum breviore. Antennarum articulus primus apice dentatus. Pronotum a latere excavatum 

 valde sellaeforme. Pro- et mesozona supra fornicatae. Margo anterior tuberculatus, in medio dente 

 valido armatus ; mesozona bituberculata ; metazona valde ascendens, supra concava, margine postico 

 areuato, denticulato, antice utrinque spinoso. Lobi laterales quadrati, margine infero incrassato, verru-

 Foramina metasterni invicem quam a marginibus lateralibus vix aequaliter remoti. Pedes antici graciles. 

 Pemora antica quam pronotum fere duplo longiora, superue obsolete deplanata, haud marginata, subtus 

 spinosa ; intermedia compressa, subtus longiuscule spinosa ; postica gracilia, sed ante medium sat incras- 

 sata, subtus tota longitudine spinosa. Lobi geniculares omnes valde spinosi. Tibiae anticae supra muticae, 

 foraminibus lineari-apertis ; tibiae intermedia^ basi vix dilatatae, superne fortiter biseriatim spinosse : 

 tibiae posticae utrinque aequaliter spinosae. 



S . Elytrorum tympana bina speculo elliptico vitreo instructa. Cerci crassi, apice arcuati, mucronati.

This genus should be placed between Xeropteryx, Redt., and Tetragonomera, Stal. It 

 is distinguished from Xerojptenjx by the form of its pronotum, the very narrow opaque 

 elytra, &c. From Tetragonomera it differs in having the pronotum spinose, with its 

 posterior margin tuberculated in the middle and its anterior margin dentated ; the 

 elytra longer, not much attenuated at the tip, and more membranaceous ; the anterior 

 femora spinose beneath and not margined above ; the intermediate tibia? with a double 

 row of spines above, &c.

Pulvo-virescens vel pallide viridis. Frons albido-liliacea. Labrum margine infero fusco. Verticis rostrum 

 latiusculum, foveolatum, basi bituberculatum. Pronotum supra opacum, ferruginescens, utrinque granulis 

 paucis. Margo anterior verruculis paucis crenatus, in medio spiua valida antrorsum vergente armatus et 

 utrinque dentem ab ilia remotum praebens. Mesozona subgranulata, arcuatim impressa, utrinque tuber-
