basal alar nervures being fulvous, the scuteliums rufous, as are also the 
basal six joints of the antennae ; the second cubital cellule is longer along 
the radius and cubitus than along the transverse cubitals, the third 
abscissa of the radius distinctly longer than the first, and about one-third 
of the length of the second, and the pleurae and the ventral surface of the 
abdomen are largely rufous. 
Sphex (I sodonta) transvaalensis , sp. n. 
Black ; the head, thorax, base of abdomen and of the legs densely 
covered with black hair ; the clypeus with a silvery pile ; wings fuscous- 
violaceous ; the nervures black ; the second cubital cellule large, oblique, 
of almost equal width ; the first and second transverse cubital nervures 
oblique, the first slightly curved below the middle, the anterior part 
straight ; the second straight, oblique ; the first recurrent nervure received 
near the apex of the cellule, the second near the apex of the basal third ; 
the second recurrent nervure is broadly curved outwardly with a short 
straight branch at its junction with the cubitus ; claws stoutly bidentate 
at the base ; the last ventral and dorsal segment broadly rounded, the 
latter with a fine keel down the middle at the apex ; the penultimate 
ventral segment with a large triangular incision extending to its base ; 
scutellum smooth in the centre, where there is a distinct shallow furrow ; 
metanotum alutaceous, the apical slope more strongly than the rest. Male. 
Length, 17 mm. 
V. d. Merwe. December. 
Mandibles bidentate, reddish to the teeth ; clypeus with the centre 
margined and transverse at the apex, the sides broadly rounded ; it is 
slightly longer than it is wide at the apex, the top is obscurely keeled in 
the middle ; eyes distinctly converging above ; ocelli separated from 
each other by a less distance than they are from the eyes ; a fine furrow 
leads down to them, and there is an oblique one running to the outer ; 
the centre of the inner orbits is bordered with silvery pubescence ; abdom- 
inal petiole three times longer than wide. 
Ampulex Jurine. 
Ampulex jansei, sp. n. 
Blue ; the head, pleurae, scutellum, apical segments of abdomen and 
legs, black, as are also the antennae ; the underside of antennal scape, 
apex of clypeal keel, and the mandibles, rufo-testaceous ; wings hyaline ; 
the nervures black ; a longish triangular cloud at the transverse median 
nervure, a shorter squarish one at the top of transverse basal touching 
the costa, one filling the basal third of the radial cellule, except in front, 
one in the apex of the first cubital cellule touching the transverse cubital 
nervure and filling the anterior three-fourths, the second cubital cellule 
entirely, this cloud extending into the discoidal, where it is twice its size ; 
the second cubital cellule is about one-fourth longer along the cubitus 
than along the radius ; apex of cubital cellule rounded ; the first recurrent 
nervure is received nearer the first transverse cubital than is the second 
from the second. Female.
