Head in front longer than usual. Eyes distinctly curved 
on the inner side. Pronotum witha distinct wide furrow in 
the centre. The post-scutellum is more narrowed towards the 
centre than is the scutellum. The striation on the median 
segment is indistinct on the basal half. Tibie and tarsi dis- 
tinctly, but not thickly, spined; the claws have a stout tooth 
at the base. The 2nd cubital cellule at the top is about two- 
thirds of the length of the first; below not much shorter than 
it; the 3rd transverse cubital nervure is roundly curved; the 
first recurrent nervure is received close to the base of the 
apical third of the cellule; the transverse basal nervure is 
straight and sharply oblique; the transverse median nervure 
is Straight and sharply oblique and is separated by almost its 
own length from the transverse basal. ‘The -accessory nervure 
in the hind wing is not interstitial. The apex of the abdomen 
is dark fulvous and is thickly covered with pale fulvous hair.
