gin, lateral keels following hind margin of eyes, then curving inward 

 and reaching hind margin. Scutellum more than twice the length of 

 vertex and pronotum, tricarinate, lateral carinae slightly curved and 

 reaching hind margin. Hind tibia with one small basal, one small 

 submedian and four or five small apical spines; spur more than half 

 the length of first tarsus, flattened, inner edge straight, outer edge 

 convexly curved, one small spine at apex. Tegmen as in Geoncossus, 

 but the apex just pointed and the radia and media only just touching, 

 not amalgamated for any distance. 



This genus is near Stohaera but the shape of the antennae 

 and the angular clypeus distinguishes it.

 Plate 6, figs. 4, 4a. 



Light yellow-brown; face below eyes yellow, legs and ventral 

 surface of thorax and abdomen lighter brown, lateral edges of prono- 

 tum and tegulae dark, spines on legs dark brown. Tegmina hyaline, 

 smoky, lighter along costal area, veins light closely beset with light 

 granules, a darker brown mark over base of costal cell, a darker mark 

 along apical half of radia and a brown spot at tip of each apical vein. 



Male pygophor with even margins; anal segment without spines; 

 styles narrow, of even width till apex where it is unequally bifurcate, 

 the inner prong being very short, the outer longer and slightly spatu- 

 late at end. 



Length 2. 5 mm. ; tegmen 3 mm.

Vertex, face between eyes, antennae and clypeus dark brown, 

 with two darker marks across face between eyes; face below eyes, 

 thorax, legs and apex of clypeus yellow; pronotum and scutellum 

 darker than ventral side, especially along the sides; a brown spot on 

 each front coxa and a round spot on each mesopleurum; front and 

 middle femora longitudinally striped with brown, a faint brown ring 

 on tibia, spur yellow with black teeth; abdomen brown, pleura and 

 margins of segments yellow. Tegmina hyaline, semiopaque, yellowish 

 over clavus; veins light, studded with brown granules, fuscous along 

 edges of third radial and first median apical veins, and over the base 

 and apex of second median and the entire of third median and first 

 cubital apical cells, except for a round white spot at apex of each 

 cell; wings hyaline with brown veins. 



Male pygophor rounded, dorsal edge roundly emarginate where 

 anal segment fits in, ventral edge with two thin, long, subparallel, 

 median spines nearly reaching to anal segment: anal segment
