truncated as viewed from above, the front of the vertex is, however, 

 a little angular at tip and obliquely cai-iiiated each side, with the 

 middle partly carinated, depressed ; front curved outwards before 

 the tip of vertex, long and wide, a very little wider than, and 

 curved at the origin of, the epistoma, with the middle line strongly 

 carinated and the lateral margins sharply reflexed, the epistoma 

 tapering and continuing the gentle curve of the sides with the 

 carina and reflexed margin ; cheeks wide, long, excavated, with the 

 reflexed borders rising prominently above the eyes. Basal joint 

 of antennae subglobose as usual. Pronotum very short, the front 

 edge upturned, with the sides curved, but little wider, and ending 

 below in a slight enlargement. Mesonotum a little wider than the 

 length includiog the scutellum, the sides expanded triangularly, 

 but the medial shield narrow, almost square, carinated on the 

 middle, and bounded by a carina on each side, the scutellum 

 acutely triangular, a little reflexed like the wings of the preceding 

 segment. Wing-covers narrow, a little bent at tip, with the inner 

 apical corner angular, shorter than the upper which is curved ; 

 costal area long and narrow, expanded at tip in contact with the 

 ovate nodal cell, its middle a little acute where the anastomosis of 

 the first fork occurs, the first ulnar areole starting from a fork 

 beyond the middle of the costal area and extending in a slight 

 cm-ve to the nodus, the second one starts in a fork near the base, 

 and continuing sends off a vein from a blunt fork on a line with 

 the nodus, at tliis point three oblique cross-veins form the base of 

 the middle anteapical areoles ; the apical areoles longer, narrow, 

 seven in number, of which the anterior one is very shore and tri- 

 angular, while the posterior one is very long and wide and ending 

 in an acute, somewhat curved angle. Posterior tibiae destitute of 

 any apparent spine.

The body relatively broader, but the wing-covers narrower, and 

 not obliquely expanding towards the tip as in the foregoing genera. 

 Colour pale fulvous, tinged with pale testaceous. Head almost 

 square, as seen from above, with the blunt triangle of the tip of 

 vertex on a line with the front of eyes, powdered wdth white ; the 

 eyes brown, somewhat bean-shaped ; antennae pale fulvous ; sum- 

 mit of front and a faint band across its middle dusky ; epistoma 

 also a little dusky. Eostrum reaching to behind the posterior 

 coxae. Wing-covers whitish yellow, or very pale fulvous, Avith the 

 costal vein mostly brown, the nodal spot whitish, and the apical 

 anterior margin of the membrane pink ; veins of the ulnar areole, 

 an oblique streak at base, the posterior border and two lines on 

 the clavus, the posterior edge of the membrane and the coarse 

 vein next inwards, and a broad uneven spot across the apical half 

 of the membrane smoke brownish ; the transverse veins of mem- 

 brane whitish. Underside and legs testaceous, with a tinge of 

 plumbeous ; tip of the venter dark brown. Disk of mesonotum and 

 surface of tergum dark brown.
