 Bantia, Stal, Syst. Mantod. p. 44. 64 (1877). 



Corpus $ apterum, crassiusculum. Caput transversum, fronte transverse carinulata. Pronotum brevissimum, 

 crassiusculum, rhomboidale, ampliatione utrinque rotundato-dilatata, deflexa; marginibus omnibus denti- 

 culatis. Elytra et alee in lateribus meso- et metanoti indicata, striata, sed baud retroproducta. Pedes 

 parum longi ; anteriores crassiusculi, breviusculi. Coxae prismaticae cantho interno distinctissime denti- 

 culato. Femora lata trigonalia, normalia, multispinosa, subtus spinis discoidalibus 4 (2 a , 3 a longioribus), 

 necnon serie tuberculorum ante spinas instructa. Tibiae graciles, compressse ; latere extern o piano, superius 

 earinato ; ungue parum arcuato ; marginibus spinis paucis armatis ; interno spinis inaequalibus, ultima 

 leviter ad superum rejecta ; externi spina ultima longiuscula, acuta, divergente. Femora intermedia et 

 postica minus gracilia quam in generibus reliquis ; postica basi distincte incrassata. Abdomen angustis- 

 sime fusiforme, carinatum, segmentis apice compressis, leviter in dentem productis, dente 2 1 segmenti 

 majore. Lamina supra-analis regulariter trigonalis. Cerci breviusculi. 



c? $ . Graciliores. Elytra latiuscula, abdomen superantia, campo marginali basi paulum dilatato, apicem versus 

 parum attenuate. Alarum vena ulnaris furcata (vel indivisa). Pedes postici longi, graciles. 



This genus approaches Thrinaconyx in its general form, but the body is much less 

 slender, though stouter than in Miopteryx. The armature of the anterior tibia? 

 somewhat resembles that ofMionyx, but the tibia? themselves are not nearly so slender.

 facie postica nigro-marmorata. Pemora regulariter spinosa, intus spinis 8 ; spinis discoidalibus 2, 3 

 longioribus ; facies infera inter spinas serie granulorum in dimidia parte basali instructa. Tibiae superne 

 compressae, spinis extus 4 (ultima longa a basi unguis remote), basique denticulis 2; intus 4 (2 a a l a 

 remota ac minor, 4 a elongata, subarcuata, ad unguem apposita) ; basi marginis nonnunquam denticulis

 margin " instead of " inner margin." Also :— the last internal spine inserted " between the 4th and the claw," 

 instead of " between the 4th and the tibia."
