basal part of the metanotum between the keels, a larger, more distinct triangular 
spot on the apex, a line on the apex of propleure on the upper two-thirds and a 
s.milar line on the apex of mesopleure, black. Antenne with the scape yellow, 
lined with black above, the flagellum dark rufous, darker above and below at the 
apex. Wings hyaline, unclouded, the costa and stigma testaceous, the nervures 
black, the areolet five-angled, the nervures closely meeting in front, the recurrent 
nervure interstitial. On the metanotum in the middle are two keels, forming an 
area of equal width ; on the sides is a keel on the apical two-thirds, there is a 
complete keel outside the spiracles and there is a keel on the lower side of the 
metapleure. The apical two joints of the hind tarsi are infuscated; the fore- 
legs are of a brighter yellow than the others. Female and Male. 
Face closely weakly punctured, densely covered with short pale pubescence. 
Eyes distinctly converging below, about one-fourth narrower at their end than on 
the vertex. Thorax smooth, impunctate ; the parapsidal furrows weakly in- 
dicated on basal slope. Abdominal petiole three times as long as it i» wide at 
the apex. Ovipositor testaceous, blackish at the apex, as long as the hind tarsi. 
There is a blackish streak on the upper, inner side of the hind femora, the hind 
knees being also black. 
Length 9 m.m. ; terebra 3 m.m. 
Temples distinctly roundly narrowed. The apical black mark on the metano- 
tum may be absent. The mandibular teeth are almost equal in length.

Black, the maxillary palpi, the basal three joints of the flagellum of antenne 
and a wider ring in its middle, white, as is also the apical fourth of the sheaths 
of the ovipositor ; the fore femora above and the apical joint of the trochan- 
ters pale testaceous, the tibie on the inner side in front and entirely so behind 
testaceous, the rest fuscous, the basal three joints of the tarsi pallid fuscous ; the 
basal two of the middle of a paler fuscous colour ; the apical third of the basal 
joint of the hind tarsi and the whole of the second and third white. Wings 
hyaline, the nervures and stigma black, the areolet in front one-quarter longer 
along the radius than it is along the first transverse cubital nervure ; it is a 
little wider at the apex than at the base and receives the recurrent nervure in 
the apex of the basal fourth ; the radius is roundly, broadly curved beyond the 
areolet ; the transverse median nervure is received at the apex of the basal fourth 
of the nervure ; the transverse cubital nervure in hind wings is broken half-way 
between the middle and the apex. Female. 
Length 17 m.m. ; terebra 8 m.m. 
Smooth, the basal half of the second abdominal] segment finely, closely punc- 
tured, and with some fine striw, the base at the sides keeled ; the pleura and 
coxe densely covered with white pubescence. ‘There is a wide, longish furrow,
