— - —— 
the areola distinetly wider than long; its spiraeles are small, 
oval, about 3 times longer than wide. Areolet 5-angled, nar- 
rowed at the top, the nervures almost uniting there; the 
transverse median nervure is interstitial; there is a stump of 
a nervure on the cubito-discal. Legs normal; the tarsi long, 
spinose, Abdomen with 8 segments; the sheath of the ovi- 
positor largely projects ; the last segment is small, the gastro- 
coeli are distinct; the ventral fold extends on to the 4th 
segment. 
The eoleur of the species is black, marked with white ; 
the last 2 segments are white with all the species; the palpi 
are long and have the 2nd joint dilated; there is a distinct 
curved keel on the lower side of the metapleurae. The areola 
is finely rugose, opaque; it is elearly separated behind from 
the base of the segment by an oblique depression, this de- 
pression being confluent with the lateral basal areae. The 
head is well developed behind the eyes; the occiput concave ; 
the face is flat, the cheeks not buceate, Iu addition to the 
keel uniting the 2 hinder coxae there is another, more or less 
distinet one, above. The abdominal petiole is long, slender, 
the post-petiole eurved ; the gastrocoeli are shallow and broader 
than long. 
The mandibles being edentate and acute at the apex 
would refer this genus to the Heresiarchini. The genus con- 
tains numerous species of small or medium size.
