Ichneumonidae. 467 
from the mesonotum, the latter there being roundly in- 
cised ; the areola coffin-shaped, more than 3 times longer 
than wide; there are 2 lateral areae besides the spiracular 
and 3 on the apical slope: the keels at the sides are 
dilated, Abdominal petiole broad at the base, clearly 
broader than the sides are high. Labrum large, pro- 
jecting. Apex of clypeus transverse. Temples wide, 
obliquely narrowed ; the occiput transverse. Discocubital 
nervure broken by a stump: transverse median nervure 
received beyond the transverse basal. Antennae ringed, 
with white, tapering towards the apex, not serrate. — 
The colour is metallic green: the petiole becomes grad- 
ually widened, the post-petiole not being separated ; the 
gastrocoeli deep, transverse: the 2nd and 3rd segments 
are separated laterally by a depression, which is reddish 
in colour. The ventral fold is on the 2nd and 3rd segments; 
there are 8 segments. Metanotal spiracles linear. 
The type of this genus looks more like one of the 
Joppini than any thing else; the broad base of the 
abdominal petiole separates it from that group and places 
it with the Platyuri. If it were not for the latter cha- 
racteristic [ should certainly have placed it in the 
Joppini only from the constriction between the base of 
the metanotum and the post-scutellum. On the other hand 
there is the fact that in some Joppini the base of the 
Ist abdominal segment is broader than it is high, dorsally 
ventrally, so that the broad form of the Ist abdominal seg- 
ment is not a peculiarity of the P/atyuri alone. I should, 
therefore, feel inclined to refer the genus to the Joppini. 
Chloroioppa viridis sp. nov. d. Dark green, metallic; 
the sides of the face more broadly than the green central 
part, labrum, base of mandibles, palpi, the upper inner 
orbits narrowly, tegulae, tubercles, the 4 anterior coxae, 
trochanters, the lower side of the 4 anterior femora, the 
base of the 4 anterior tibiae broadly above and entirely 
below; their tarsi, except the apical joint, more than the 
basal third of the hind tibiae and the hind tarsi, except 
the apical joint, yellow. Scape of antennae blue white at 
the base below, the flagellum black, a broad white ring 
in the middle. Wings hyaline, the nervures and stigma 
black. — Length 15 mm.
