Microrhogas gen. nov. 
Oceiput margined as are also the cheeks. Parapsidal furrows 
wide, complete, the mesonotum distinetly trilobate. Scutellum with 
a large, wide, deep, rugose fovea at the base, the base of the fovea 
transverse, margined, the sides rounded. Metanotum irregularly, not 
very clearly areolated. Mesopleurae with a curved, wide erenulated 
furrow. Radius originating from the middle of the stigma. Transverse 
median nervure received elearly beyond the transverse basal ; the recur- 
rent nervure in the apex of 1°% cubital cellule, distinetly distant 
from the transverse cubital; the 2" eubital cellule quadrate, longer 
than wide, sliehtly narrowed towards the apex. There is no radius 
in the hind wings, but the fore apical half is bordered by a nervure. 
Abdomen sessile, the basal 3 segments large, elosely, regularly longi- 
tudinally striated ; there is a erenulated furrow between the 2"4 and 
3"d segments; the ovipositor is more than half the length of the 
abdomen. 
The 1° abseissa of radius is fully one third shorter than the 
2nd, Palpi not dilated. Tarsal joints elongate. 2” discoidal cellule 
closed. Eyes large, slightly incised at the antennae, the malar space 
about one fourth of their length. The basal 2 segments of the ab- 
domen are longer than wide, the 3"@ wider than long, almost square ; 
the apical segments obliquely narrowed. Femora longish, not thickened, 
sliehtly narrowed towards the base. Metathoracie spiracles small, round. 
In the system of Szepligeti this genus (Öf. Gen. Ins., Braco- 
nidae, p. 76) comes nearest to Megarhogas, which may be known 
from it by the parapsidal furrows being almost absent, and by the 
elliptical metathoracie spiracles. 
Microrhogas foveatus spec. nov. 
Testaceous, the upper three fourths of propleurae, upper half 
of meso- and metapleurae, metanotum and the basal three segments 
of the abdomen, black; the antennae testaceous, black above; legs 
pallid testaceous, the apex of the 4 hinder femora and the hinder 
tibiae fuscous; wings hyaline, iridescent, the stigma and nervures 
testaceous. Face, pleurae and metanotum covered with white pubes- 
cence, the metapleurae more thickly than the rest. Upper half of 
pro- and mesopleurae and the whole of the metapleurae coarsely reti- 
eulated; the metanotum more closely reticulated. The black basal
