Pseudischnoptera. Saussure, Rev. Zool. (2), Vol. 21, p. 112 (i85g). 



Characters. — Body depressed. Antennse incrassated and hirsute throughout their entire 

 length. Pronotum trapezoidal, anterior margin arcuate, not covering vertex of head, posterior margin 

 truncate, exposing the scutellum. Tegmina and wings longer than the abdomen in the male, shorter than 

 the abdomen in the female. Tegmina coriaceous and punctate, their external margins sinuate, discoidal 

 sectors longitudinal. Wings coloured ; ulnar vein giving off branches to apex of wing and to the dividing 

 vein. Supra-anal lamina in the male triangular, sub-genital lamina elongate and with two styles. Cerci 

 long, mid- and hind- femora unarmed on the anterior margin beneath, but with four to five spines on 

 the posterior margin and with one median spine, near the trochanteral articulation. 



Geographical distribution of species. — South America, West Indies.

 ramose (2), all the rami directed towards the apex of the wing; triangular apical field sometimes present.
