A medium -sized greyish red-yellow species with the thorax 

 greyish black, abdomen with a narrow median, and fainter lateral 

 stripes. Frontal stripe narrow with a long reddish brown or brown 

 callus; antennae and legs pale reddish brown ; wings clear with costal 

 border yellowish. 



Female. Head a little broader than the thorax, moderately 

 long and arched. Frontal stripe rather narrow, slightly contracting 

 from the vertex to the eye-angles, and about seven times as long as 

 its narrowest part or about five times as long as its broadest part, 

 covered with yellowish brown tomentum and with very short black 

 hairs which gradually become sparse and inconspicuous towards the 

 lower part where the pubescence is hardly recognisable ; frontal callus 

 reddish brown or brown, very slightly convex and oblong, not reach- 

 ing the eyes, diminishing to a long narrow line, this linear part being 

 distinctly longer than the broad part and sharply pointed upwards ; 

 vertex slightly darker, with rather conspicuous black pubescence which 

 is slightly longer and much denser than that on the part just below 

 the vertex behind which there is some distinct longer (still short) 

 black bristly hairs ; frontal triangle nearly flat, covered with yellowish 

 tomentum, and in the middle there is a fine but distinct longitudinal 

 sulcus throughout, separated from each cheeks by a more or less dis- 

 tinct shallow groove which is hardly perpendicular but slightly diver- 

 gent outwardly and which is not reaching to the eye-margin with a 

 somewhat conspicuous but very shallow depression at its end. Face 

 somewhat strongly convex with the prominent epistoma which is com- 

 paratively large and is slightly widened below and is broader than long,
