in the middle. Middle of metanotum irregularly transversely striated. The

beyond the middle. Pygidium thickly covered with long, black hair, and more 
sparsely in the centre with shorter fiery red hair. Female.

There is a shallow wide furrow down the centre of the metanotum, it is wider 
and deeper on the upper half of the apical slope ; the upper half of the meta-

Black, velvety, the head densely covered with longish black hair all over, 
the metanotum covered more sparsely with still longer hair ; wings uniformly 
fuscous viclaceous, the stigma and nervures black the 2nd abscissa of radius 
about one quarter longer than the 3rd, which is fully one quarter shorter than 
the roundly curved apical ; the transverse median is received distinctly beyond 
the transverse basal ; both the recurrent nervures are received shortly beyond 
the middle of the cellule, the Ist at a greater distance than the 2nd ; the acces- 
sory nervure in the hind wings is received shortly beyond the cubitus. Eyes 
distinctly converging at the top ; the hind ocelli separated there by the same 
distance as they are from the eyes. Apex of clypeus broadly rounded, depressed, 
margined. Apex of pronotum broadly rounded. not angled in the middle.

the costal cellule, the radial, the 4 cubitals, the apical 2 lighter coloured 
behind, light fuscous violaceous, the costa and nervures black, the stigma 
livid testaceous, the Ist abscissa of radius one-fourth of the length of the 2nd ; 
the 3rd is as long as the basal 2 untted, the Ist recurrent nervure is received 
at the base of the apical fourth, the 2nd shortly before the middle. the accessor y 
nervure in hind wings received half the length of the transverse cubitus beyond 
the cubitus. Apex of pronotum bluntly :ounded. Metanotum short, rounded 
from the base to the apex. Claws with 1 tooth. The long spur of the hind 
tibie one-thirdof the length of metatarsus. The hair on the front, face, clypeus
