KAYANIA, gen. nov. 
Vertex transverse, much shorter than broad, centrally and 
laterally ridged, the anterior margin subtruncate, wider than basal 
margin; face about as long as broad, tricarinate, the sublateral 
carinations not reaching the posterior margin, and broader and less 
acute than the central carination, the lateral margins ampliately 
reflexed and sinuately narrowing towards clypeus; clypeus only 
slightly shorter than face, elongate, its apex truncate, broadly 
centrally ridged ; pronotum longer than vertex, subconically pro- 
duced between the eyes, lateral margins obliquely rounded, basal 
margin moderately concave; mesonotum tricarinate, the disk flatly 
raised ; legs of moderate length, posterior tibize with a strong spine 
near apex ; tegmina less than twice as long as broad, costal mem- 
brane nearly as broad as radial area, the first transversely veined, 
two series of longitudinal veins on apical area, the outermost boun- 
ded by an almost straight series of transverse veins, the innermost 
irregular in size and bounded by a waved and sinuated series of 
short transverse veins, remaining area somewhat thickly trans- 
versely veined, claval area strongly granulose; wings about as 
broad as tegmina, two transverse veins before apex.

Allied to Sephena, Melich., but differing in the shape of the face 
and the venation of the tegmina.
