the second abdominal segment broadly below, the third, fourth, and fifth 
almost entirely, the sixth not so broadly and the seventh entirely, 
ferruginous ; the mandibles except the teeth and the palpi pale yellow ; 
the four front legs whitish, the coxae black, the femora darker coloured, 
the pale colour suffused with fuscous ; the hind legs black, the femora 
obscure dark rufous ; the tibiae with a broad pale band commencing near 
the base and extending to shortly beyond the middle ; the spurs white. 
Wings clear hyaline, the stigma and nervures black, the areolet four-angled, 
it being distinctly angled where the recurrent nervure is received at the 
apex of the basal fourth ; in front the transverse cubital nervures unite ; 
the transverse median nervure is received shortly beyond the transverse 
basal ; the apical longitudinal nervures in the hind wings are faint ; the 
cubitus is broken shortly below the middle. Female. 
Length, 10 mm. 
Warmberg (Zoutpansberg District). March. 
Eyes distinctly incised on the inner side. Face closely, somewhat 
strongly punctured, almost reticulated ; the vertex closely, but not quite 
so strongly, punctured. Thorax closely punctured, the puncturation on 
the metathorax closer ; on the mesopleurae the punctures are larger and 
more widely separated. There are no keels on the metanotum, the apical 
slope of which is widely furrowed, the apical half of the furrow being 
distinctly, transversely striated. The lower part of the propleurae is 
strongly obliquely striated. 
Pimplomorpha nigro-ornata , sp. n. 
Rufo-testaceous ; the antennae, tips of mandibles, ocellar region, 
three large marks on mesonotum, the central wider and shorter than the 
others, a minute spot on either side of the metanotum at the base, a conical 
spot on the base of mesopleurae below, a streak on mesosternum, an 
irregular spot at the base of the post-petiole, a distinct line on either side 
of the basal half of the second segment, two squarish spots on the base of 
the third, a semicircular mark on the sixth and the basal half of the first 
ventral, black ; wings hyaline, the nervures and stigma black. Female. 
Length, 11 mm. ; terebra, 9 mm. 
Van der Merwe (Pretoria District). November. 
The pubescence is short, dense, and white ; the puncturation on the 
head and thorax dense and close ; it is stronger on the metanotum, which 
has the apical slope rather strongly transversely striated in the middle ; 
there is an indistinct, longer than wide, areola, the posterior and apical 
keels of which are indistinct. The second abdominal segment is closely 
striated. The apical nervures in the hind wings are faint ; the transverse 
cubital nervure is broken shortly below the middle, the recurrent nervure 
is largely bullated at its junction with the cubitus. There are two fuscous 
spots on the occiput. The pleurae and scutellum are largely yellow. 
May be known from P. trilineata, Cam., the type of the genus (Annals 
of South African Museum, V, 96) by the base of the metanotum having 
only two small 'marks, not the basal half black, by the dorsal abdominal 
segments being marked with black lines and spots and by the second being 
striated.
