the second about half the length of the third ; the radial cellule short and 
wide, extending to the apex of the cubitus ; the apical abscissa of the 
radius larger than usual, straight ; the appendicular cellule longer than 
usual ; there is a distinct, clearly defined furrow down the lower half of 
the front ; the first transverse cubital nervure is broadly, roundly curved. 
Notogonia transvaalensis , sp. n. 
Black ; densely covered with silvery pubescence, dense on the face, 
clypeus, and orbits ; wings hyaline, tinged with violaceous ; the apex 
with a fuscous margin ; the nervures black ; the second abscissa of the 
radius about one quarter shorter than the third ; the apex of radius 
straight, obliquely sloped ; the two recurrent nervures almost united at 
the cubitus, received at the apex of the basal third ; the lower part of 
the first transverse cubital nervure is straight, obliquely sloped ; the upper 
(and longer) is more sharply oblique, and slightly, broadly rounded ; 
mesonotum and scutellum finely, minutely punctured ; the metanotum 
with a fine keel down the basal half, the keel becoming finer towards the 
apex ; it is obscurely, finely, transversely striated, the striae stronger and 
more widely separated on the sides of the apical half ; the apical slope is 
more distinctly striated, the striae clearly separated and stronger on the 
sides; there is a closely striated belt on the centre of the basal half of 
the metapleurae, the striae longer on the middle ; pygidium covered with 
silvery pubescence, closely, rather strongly striated, the lateral striae 
curved. Female.

Rietfontein No. 24, Pretoria District. January. 
Tibial and tarsal spines stout, black ; the apex of the hind tibiae 
and the base of the outer hinder spur covered with pale golden pile. 
Notogonia brevicarinata , sp. n. 
Black ; covered with silvery pile ; the wings hyaline, distinctly tinged 
with violaceous ; the apical margin in both wings clouded ; the basal 
abscissa of the radius about one quarter shorter than the following two 
united ; the second half the length of the third ; the second recurrent 
nervure is received near the apex of the basal third ; the two recurrent 
nervures are separated by slightly more than half of the second abscissa 
of the radius ; the fore half of the first transverse cubital nervure is more 
obliquely bent than the posterior, and is slightly, roundly curved. On the 
centre of the basal fourth of the metanotum is a stout longitudinal keel, 
bordered by fine striae ; the apical slope bears fine, widely separated 
striae ; the lower apical part of the metapleurae irregularly, obliquely 
striated ; the third and fourth joints of the antennae are equal in length ; 
Jthe eyes at the top are separated by the length of the third and half the 
length of the second antennal joints united ; apex of clypeus broadly 
rounded ; the vertical and longitudinal furrows on the mesopleurae 
smooth ; pygidium twice longer than it is wide at the base. Female. 
Length, 12 mm.
