is received shortly before the cubitus ; the inner eye orbits from the 
antennae to near the top are lined narrowly with pale yellow ; the hinder 
ocelli are separated from each other by almost the same distance as they 
are from the eyes ; temples almost obsolete, the occiput transverse ; 
clypeus, face, scutellums, and the parts bounding them, densely covered 
with white pile ; apical slope of metanotum densely covered with depressed 
white pubescence ; tibial and tarsal spines long and black ; the long spur 
of hind calcaria three-fourths of the length of the metatarsus. Male. 
Length, 7 mm.

The eyes are curved on the inner side, and converge distinctly below ; 
the antennal scape is yellowish-white in the centre below ; the third 
antennal joint is nearly as long as the fourth. 
Jansea, gen. nov. 
Wings without a radial cellule ; there are two cubital cellules ; the 
two transverse cubital nervures are united to the stigma by a short pedicle, 
the second cubital cellule being narrowed to a point in front ; it receives 
both recurrent nervures ; there is no radius ; the cubitus does not extend 
to the apex of the wings; the dis oidal nervure is short ; in the hind wings 
the radial, cubital, and diskoidal nervures are present, and extend to the 
apex of the wings, but there is no transverse cubital nervure ; the accessory 
nervure is short; head, as in Pompilus, wider than the thorax ; there is 
no malar space ; tibiae spineless ; abdomen sessile ; claws simple ; 
ocelli in a wide triangle ; hind tarsi long, the basal two joints united as long 
as the tibiae ; the anal nervure is straight, not curved down at the 
base. 
The head and body are as in Pompilus. It is a genus easily recog- 
nized by the absence of a radius, and by the two transverse cubital nervures 
being united direct to the stigma. In the described genera they are united 
to the radius. 
Jansea longitarsis, sp. n. 
Black, shining, probably when fresh covered with a silvery pile 5 
wings hyaline to the second transverse cubital nervure, fuscous beyond 
it ; the stigma and nervures black ; the first transverse cubital nervure 
is roundly, obliquely curved towards the cubitus ; the second is broadly 
rounded outwardly ; apex of clypeus transverse, with the sides at the 
apex rounded ; temples broad, rounded ; the occiput not transverse ; 
the third joint of the antennae about one-fourth longer than the fourth ; 
pronotum as long as the metanotum, and a little longer than the meso- 
notum with the scutellum. Male. 
Length, 6 mm. 
Pretoria. December. 
Palpi long and black ; the fore coxae are thicker and longer than the 
others ; apex of metanotum broadly rounded ; the first recurrent nervure 
is received close to the base, the second at double the distance from the 
apex.
