 anterior lobe as well as on the posterior one. Tegmina with 



the costal edge coriaceous 4. valida, Rehn. 



b 2 . Tegmina provided with well-defined mottling in the discal field. 

 c 1 . Antennae with the basal joints only slightly depressed or 



flattened. Tegmina semimembranous throughout .... [6. fuscovittata, Thorn.] 



c 2 . Antennae with the basal joints considerably depressed or 



flattened, thus giving these segments a dagger-like form. 



d 1 . Large and robust; the head large and wide; pronotum 



with faint indications of the lateral dusky discal stripe on 



the sides of the extreme front edge. Wings markedly 



tessellate with hyaline 7. robusta, sp. n. 



d 2 . Form more slender ; the head not unusually large or broad ;

A 1 . Lateral carinae of pronotum only gently bowed. Tegmina always 



plainly and decidedly mottled in the discal area. Wings pale
