Black ; the first abdominal segment, except the basal slope, the 
second and third segments, red ; the apices of the others piceous ; the 
wings hyaline ; the stigma and the nervures beyond its base pallid testa- 
ceous ; the head, thorax, and base of abdomen densely covered with 
white pubescence ; the ventral surface of abdomen, the apices of dorsal 
segments, and the legs, more sparsely haired ; the hind tibiae and tarsi 
covered, but not thickly, with stiff black spines ; metanotum closely 
reticulated, the basal striae roundly curved ; the apical slope is more 
finely reticulated ; mesonotum and apical half of scutellum closely 
punctured ; the base of scutellum smooth and shining ; front closely 
punctured, a wide furrow, with obliquely sloped sides, down its centre ; 
the clypeus is more shining and closely punctured. Male.

Black ; densely covered with silvery white hair, the pygidial area 
with depressed golden pile ; the palpi and calcaria rufo-testaceous ; the 
tibial and tarsal spines of a paler rufous colour ; wings hyaline ; the stigma 
and nervures testaceous ; the radius thickened at the base, not much 
shorter than the second and third united ; the second one- third of the

The eyes converge above, separated there by the length of the basal 
two joints of the flagellum united. The silvery pile forms distinct bands 
on the apices of the abdominal segments. The middle of the clypeus is 
almost transverse ; there is no distinct puncturation on the front and 
vertex ; the first joint of the fore tarsi has six, the second and third two, 
the fourth one spine ; there is no clear appendicular cellule in the fore 
wings.
