head. Parapsidal furrows shallow, not reaching to the scutellum. Apex 
of mesonotum depressed in the middle, reticulated. Scutellum almost 
smooth, shining. Metanotum shagreened, broadly round at the apex, 
with the sides slightly projecting. Pleurae almost smooth. Abdomen 
closely reticulated, more strongly towards the apex than at the base, which 
is transverse with the outer edges projecting ; the apical teeth about four 
times longer than wide and narrowed towards the apex. 
Gasterotheca areolata , sp. n. 
Rufo-testaceous ; the antennae, apex of mandibles, stemmaticum and 
sheaths of ovipositor black ; covered closed with short white down ; wings 
hyaline, tinged with fulvous, the costa and nervures black, the nervures 
testaceous. Female. 
Length, 7 mm. 
Waterval (Zoutpansberg District). December. 
Centre of face with a smooth broad keel which becomes gradually 
widened (but not much) from the base to the apex. Sides of face, front 
and vertex rugose, the latter two more strongly than the former ; the 
top of the eye orbits obliquely, closely striated behind. Mesonotum 
trilobate, the middle lobe not narrowed to a point at the apex and with 
a shallow furrow down the centre ; it is followed by a strongly longitudinally 
striated depression ; there is a narrower oblique furrow on the outer lobe 
on the apical half. Scutellum finely rugose ; it is followed by a smooth, 
shining depression, with a keel down the centre. The base of metanotum 
with a large, almost semicircular depression or area in the centre, bearing 
some stout striae ; this is followed in the centre by a large triangular 
area, the keels bounding it being curved towards the apex ; it is irregularly 
transversely striated and has down the centre two keels which slightly 
converge towards the apex ; there are a few transverse keels between 
them ; the sides of the metanotum are margined by a keel. Propleurae 
smooth except for a few striae in the central hollow. Mesopleurae finely, 
closely, indistinctly punctured; there is a wide oblique furrow on the base 
near the top, this furrow being striated moderately strongly and extends 
from the base to the apex. Except at the depressed base the metapleurae 
are rugosely, obliquely punctured. Abdomen closely, rugosely reticulated 
with a narrow keel down the centre of the basal half ; this central keel is 
enclosed by a broad rufous-fuscous mark, which extends beyond it ; the 
apical spines are long — about five times longer than they are wide at the 
base — and become narrowed towards the apex ; the part between them 
forms a broad crenulated round curve, the sides at the apex being also 
crenulated. 
Minanga bimaculata , sp. n. 
Rufo-luteous ; the antennae and a wide longish line on the lateral 
lobe of the mesonotum, black ; wings hyaline, the costa, parastigma, and 
stigma black, the nervures testaceous, darker coloured beyond the stigma. 
Female. 
Length, 4*5 mm.
