clypeus keeled in the centre and at the sides; rostrum long, comparatively stout ; pronotum with a 
central keel and very faint traces of side-keels ; tegmina transparent, with a very large and broad costal 
membrane; the three principal veins of the corium of about equal length, the apical and subapical areas 
more or less regular, the posterior claval vein situated at some distance from the suture and joining this 
towards the apex of the clavus, the transverse basal vein short, stout, and abruptly and shortly bifurcate 
at the middle of the clavus, one branch curved and touching the clavus, and the other straight and 
touching the posterior vein ; posterior tibie without spines. 
_ This genus includes an exceedingly pretty and distinct little species; in facies it 
resembles a minute Cixius.
