This is a Macronemiirus, spurs equal nearly three joints. A slen- 

 der-bodied species with clouds at ends of all cross-veins; pronotum 

 not very pale and marks not in strong contrast, but distinct; antennae 

 hardly diameter apart, a large mark above and below the antennae 

 dark ; vertex dark leaving a pale band across the front, two sub- 

 median, rather elongate spots behind on vertex. Wings moderately 

 narrow, costals simple, 9 cross-veins in fore wings before radial 

 sector, 7 branches of radial sector, in fore wings four cross-veins 

 between anal and cubital fork, in hind wing but one such vein. In 

 fore wing the radial sector arises a little beyond cubital fork, in hind 

 wing plainly before. Femora pale, tibia marked within, tips of tarsal 

 joints pale, last joint more than twice as long as first, which latter is 

 no longer than second and third.
