2 . Gracilis, prasina. Caput latius quam altum, vertice quam oculi paulum altiore, subareuato, subtiliter 

 4-sulcato. Scutellum faciale quinquies latius quam altum, planum, margine supero subbisinuato. Ocelli 

 mimiti, per carinulam arcuatam conjuncti. Prons supra illos cannula transversa (vel sulco) subangulata 

 notata. Pronoti ampliatio tertiam partem prothoracis aequans, parallela, supra coxas vix dilatatius- 

 cula. Elytra ad 5 m abd. segmentum extensa, basi et apice coarctata, apice anguste rotundato, haud 

 retro vergente, margine antico arcuato ; campo marginali tertiam vel quartam partem latitudinis elytri 

 efficiente ; campo discoidali semi-membranaceo, basi et campo anali vitreis. Alae valde breviores, angustae, 

 subbyalinae, venis et margine antico virescentibus ; campo anteriore angustissimo, posteriorem superante, 

 apice rotundato ; vena ulnari biramosa. Coxae anticae subtus ad marginem posticum subgranulosae. 

 Pemorum spinae externae subperpendiculares ; prima longa ; spinae discoidales prima? 3 subperpendiculares. 

 Tibiae spinis utrinque 15-17. (Lamina supra-analis incompleta.) Cerci subangusti, longe acuminati, 

 abdomen longissime superantes.

 Brunner de W. BeVis. Syst. Orthopt. p. 61. 



Caput compressum, trigonali-lenticulare. Ocelli superi inter se quam ab ocello antico minus remoti. Oculi 

 parum prominuli, superne acuti (tuberculati). Pronotum breve, rhomboidale ; ejus pars postica quam 

 pars antica paulo longior, vix carinulata ; ejus margines $ denticulati. Elytra et alae § d 1 rudimentaria. 

 Pedes antici robusti; femora spinis discoidalibus 4, spinis apicalibus minutis; tibiae toto longitudine 

 spinosae, spinis 11 : 11. Pedes 2*, 3* longi ; femoribus basi leviter incrassatis ; tarsorum posticorum 

 articulus primus elongatus, reliquis computatis attamen brevior. Lamina supra-analis elongato-trigonalis, 

 carinata ; cerci longi. 



This genus differs from Ameles in the position of the ocelli, and also in the long hind 

 legs and coloured wings. In Ameles the superior ocelli are more distant from each 

 other than they are from the inferior one, and the posterior metatarsus is scarcely 

 longer than the second joint of the tarsus.
