pointed at the apex ; in front it is bordered by a distinct nervure which 
extends beyond the radius ; the recurrent nervure is received at the base 
of the apical fourth of the first cubital cellule ; the cubitus ends shortly 
beyond the transverse cubitus ; the anal nervures is a little longer than 
it. There is a narrow, smooth, shining line down the middle of the second 
and third abdominal segments. Head fully as wide as the thorax. The 
basal alar nervures are paler than the apical. The amount of testaceous 
colour on the legs appears to vary. 
I place this species in Foersteria rather than in Sigalphus, because 
the second abdominal segment is longer than the third. 
Agathidinae. 
Disophrys erythropus, sp. n. 
Rufous ; the antennae black, the wings fuscous, the first cubital 
cellule except along cubitus, an irregular cloud along the outer side of the 
recurrent nervure, extending below it to the anal nervure, a cloud before 
the transverse basal nervure, a smaller one before the transverse median 
and a still smaller one on its outer side, and one in the base of the radial 
cellule in the posterior wings, hyaline. Metanotal areola smooth, triangular, 
appendiculated ; there is a large irregular lateral area ; the keel bounding 
it is roundly curved ; from its middle a straight keel runs to the apex, 
there being a rounded keel outside this. 
Face closely punctured, the front and vertex smooth. Pro- and 
mesothorax weakly, sparsely punctured, the furrows weakly crenulated. 
The basal part of the metanotum smooth in the centre, the sides with broken 
striae; the apical part in the centre closely, strongly, the sides sparsely, 
irregularly striated. The lower mesopleural furrow is shallow and is 
strongly crenulated. Male. 
Length, 10 mm. 
Waterval (Zoutpa> n sberg District). November. 
Head, thorax, and legs covered closely with a white pile. The alar 
stigma is pale ochraceous except at the apex ; the nervures at the hyaline 
spaces are pale, the other nervures are darker, especially on the outer 
edges. Palpi of a paler rufous colour than the head. The suture between 
the first and second abdominal segment is deep laterally, very shallow in 
the centre. Areolet about one-fourth shorter along the radius than along 
the cubitus ; the first transverse cubital nervure is roundly curved. 
Allied to D. rufa , Cam. (Annals South African Museum, V, 38) which 
may be known from it by the head being largely marked with black. 
Crassomicrodus curvinervis, sp. n. 
Luteous ; the antennae except the base and inner side of the scape, 
the back of the second abdominal segment broadly in the middle, the 
sheath of the ovipositor and the tarsi, black ; wings fuscous hyaline ; 
lighter coloured at the base, the stigma and nervures black, the transverse 
cubital nervure roundly curved, becoming gradually thickened in front, 
the end oblique, the first transverse cubital nervure straight, oblique, 
the second roundly curved, the recurrent nervure with the front half
