Black. the head and thorax covered with white pubescence, which is densest 
on the mesopleurz and base of metanotum, and forms a distinct band on the 
apex of the pronotum: on the mesopleure and metanotum there is a silky, 
white pile under the hair: the apex of the Ist abdominal segment and the whole 
of the 2nd to 4th ferruginous, the segments fringed with ferruginous, stiff hair : 
the apex of the Ist antennal joint, the 2nd and the base of the 3rd are tesca- 
ceous, the testaceous colour on the 3rd. paler in tint ; legs thickly covered with 
stiff white hair ; the spurs white ; wings fuscous violaceous, almost hyaline at 
the base to the transverse median and transverse basal nervures : the stigma 
and neryures black; the radius with 5 angles: the basal rounded, the 2nd 
about one-fourth longer than the 3rd; the 4th and 5th oblique, forming an angle 
at their junction, the apical more sharply oblique, thicker and a little shorter 
than the 4th; both the recurrent nervures are received shortly beyond the 
middle. The basal ventral segment is broadly rounded at the base, there is 
a rufous broad triangular tooth. There is a smooth, flat shining keel down the 
centre of the scutellum, widened slightly towards the apex, commencing near 
the base and reaching to the top of the apical slope. Metathorax reticulated, 
the apical slope straight, oblique; the areola open at the base, the keels 
broadly rounded outwardly there, narrowed at the apex into a sharp point. 
Pro and mesonotum, with the scutellum strongly punctured ; there are 2 dis- 
tinct deep furrows on the apical two-thirds of the mesonotum ; the pro- 
mesopleure and basal half of metapleure almost smooth, the apical half 
of the Metapleure reticulated. 
Male. Length 15 m.m. 
Head nearly as wide as the thorax. The hair on the face and clypeus is 
denser and longer than onthe front. Clypeus smooth, its apex rounded 
Tegule moderately large, smooth, the apex curled up. The basal slope of Ist 
abdominal segment is straight, oblique, and is more strongly and sparsely 
punctured than the apex. The pygidium is closely, distinctly, not very strongly 
punctured, « smooth iurrow dewn the centre and densely covered with longish 
black, stiff hair. Tibial and tarsal spmes white.
