Notogonia pretoriaensis, sp. n. 
Black ; covered with silvery pile, which forms broad bands on the 
apices of the abdominal segments ; wings hyaline, distinctly tinged with 
violaceous ; the stigma and nervures black ; the first abscissa of the 
radius as long as the following two united ; the second fully half the length 
of the third ; the two recurrent nervures are almost united, and are received 
very shortly beyond the apex of the basal third ; the first transverse cubital 
nervure is obliquely sloped, the anterior half slightly rounded, the posterior 
straight ; it is bullated near the radius and below the middle ; the base 
of the metanotum is weakly, the sides towards the apical slope more strongly 
striated ; there is a longitudinal keel down the centre of the basal half ; 
the apical slope is more strongly and regularly striated ; the metapleurae 
not striated ; the calcaria, tibial, and tarsal spines black ; the claws without 
a tooth. Female. 
Length, 14 mm. 
Pretoria. May. 
Base of mandibles densely covered with depressed white pile ; palpi 
black, covered with white pile ; the second and third joints united are 
as long as the scape ; the third is a little longer than the fourth ; the eyes 
at the top are separated by the length of the third antennal joint ; the 
furrow down the base of the mesopleurae is distinct and closely crenulated ; 
the longitudinal furrow is distinct and smooth ; apex of clypeus broadly 
rounded, depressed in the middle ; the wings are uniformly coloured ; 
the radial cellule moderately long and wide.

Liris nigropilosellus, sp. n. 
Black ; densely covered with black pubescence, which is longer and 
denser on the metathorax ; wings uniformly fuscous-violaceous ; the 
stigma and nervures black ; palpi black ; the apices of the joints testa- 
ceous ; mesonotum and scutellum closely, distinctly punctured, the 
punctures distinct and clearly separated ; the punctures on the scutellum 
more widely separated than they are on the mesonotum ; the metanotum 
is more closely, regularly, and strongly punctured, as are also the pleurae ; 
the abdomen is finely and closely punctured ; the pile on the pygidium 
is black ; eyes distinctly converging above, separated there by less than 
the length of the second and third antennal j oints united ; the first abscissa 
of the radius as long as the third ; the second as long as the space bounded 
by the recurrent nervures, which is as long as the space bounded by the 
first transverse cubital and the first recurrent nervures ; the second recur- 
rent nervure is received shortly beyond the middle ; the first transverse 
cubital nervure is broadly, roundly curved behind ; the second at its 
junction with the cubitus is straight, forming an angle with the much 
larger anterior part ; tibial and tarsal spines black. Male.
