colour, black at the base, the spurs dark testaceous. Head, thorax, and 
apical segments of abdomen covered with white pubescence. Wings 
hyaline, a wide pyriform cloud behind the transverse basal and transverse 
median nervures, the narrowed end in front, the posterior rounded ; it 
does not reach to the costa, but extends to the posterior edge of the wings ; 
there is a large, irregular pyriform cloud, narrowed in front extending 
from the anterior to the posterior part of the wing ; it commences at the 
base of the disco-cubital nervure ; the apex is clouded ; there is a fainter 
cloud in the front of the posterior wings beyond the middle at the transverse 
radial nervure. Head closely punctured, the face more strongly than 
the vertex, the clypeus smooth at the apex, as is also the malar space ; 
the temples shining, not very closely punctured. Mesonotum irregularly, 
rather strongly and closely transversely striated, the scutellum smooth ; 
the metanotum closely irregularly transversely striated. Pleurae closely, 
rugosely punctured, the puncturation strongest on the metapleurae. The 
striae on the basal three abdominal segments are strong and clearly 
defined. Female. 
Length, 4 mm. ; terebra, 2 mm. 
Pretoria. February. 
The tegulae are black ; the base of the costa is white. Outside the 
clouds the alar nervures are pale. 
Lienella annulata, sp. n. 
Black, shining ; covered with a white pubescence, which is longest 
and densest on the face and metanotum, shorter and denser on the legs 
than on the body ; the antennal scape, the basal three or four joints of 
the flagellum except above, mandibles, the four front legs and the posterior 
trochanters rufous ; the palpi long and white ; wings hyaline, the stigma, 
costa, and nervures black ; a dark fuscous cloud extends from the base of 
the radius to the end of the areolet, and posteriority near to the anal 
nervure, the cloud becoming slightly roundly narrowed behind ; the disco- 
cubital nervure broken by a minute stump, the transverse cubital nervure 
in the hind wings broken shortly below the middle. The base of hind 
tibiae annulated with pale yellow. Male. 
Length, 5 mm. 
Valdesia (Zoutpansberg District). November. 
Front depressed in the middle, closely transversely striated. Face 
opaque, the clypeus shining, sparsely punctured, the vertex more closely, 
the temples more sparsely and weakly punctured. Third and fourth 
joints of the antennae almost equal in length. Middle lobe of mesonotum 
somewhat strongly punctured, a furrow, bordered by smooth and shining 
spaces down the middle, the lateral lobes irregularly, obliquely or trans- 
versely striated, the centre smooth, the striae wide and deep ; those near 
the apex roundly curved. Depression at the base of scutellum wide, with 
two keels down the middle. Scutellum not very closely punctured, the 
sides keeled. Metanotum regularly areolated, the areola three times longer 
than wide, obliquely narrowed at the base, where it is united to a triangular 
area ; the other areae are coarsely, irregularly reticulated — striated.
