Ammophila transvaalensis, sp. n. 
Black ; the head and thorax densely covered with silvery pubescence 
and hair ; the antennal scape, mandibles except the teeth, prothorax except 
at the base narrowly, tubercles, tegulae, and the legs, red ; the anterior 
femora at the base behind, and the middle coxae, trochanters, femora, 
tibiae, and the hind legs behind, black ; wings hyaline, distinctly tinged 
with violaceous ; the nervures black ; the first abscissa as long as the 
second, the third one-quarter of their length ; the third transverse cubital 
nervure being obliquely curved from below the middle towards the top of 
the second ; the first recurrent nervure received near the apex of the basal 
third ; the second received half the distance from the second ; mesonotum 
obscurely, transversely striated ; the scutellum longitudinally, finely 
rugose, a distinct smooth furrow down its centre, the base of the furrow 
rounded, the apex acute ; post-scutellum rugosely punctured ; metanotum 
transversely, irregularly striated laterally ; the centre more finely reticu- 
lated ; there is no distinct central area ; pleurae closely, not very strongly, 
punctured, the puncturation hid by the dense white pubescence ; they are 
more densely pilose than the upper parts of the thorax. Male. 
Length, 24 mm. 
Eyes slightly converging below ; clypeus longer than wide, its apex 
slightly, widely incised, or at least not transverse ; there is a smooth tubercle 
in its centre ; third antennal joint about one-fourth shorter than the fourth 
and fifth united ; tarsal spines strong. 
Allied to A. ferrugineipes Lep. ; that species may be known from it 
by the basal five or six joints of the flagellum being red, by the clypeus 
being red, by the third transverse cubital nervure being more gradually 
rounded to the bottom, by the basal abscissa of the radius being about 
one-fourth longer than the second, and the hind tibiae and tarsi are red, 
not black, nor is there a distinct smooth furrow down the centre of the 
scutellum. 
Ammophila maculifrons, sp. n. 
Black ; the head red, except for a large mark on the front, wider 
than long, not extending to the lower edge, nor to the eyes, and above 
extending shortly behind and enclosing the ocelli ; below a line runs down 
the middle to the antennae ; the basal four joints of the antennae, the 
fifth except above, the raised apical part of the prothorax, tegulae, 
and tubercles, red ; the apical four segments of the abdomen blue ; 
the legs red ; the coxae, trochanters, and femora above, black ; the 
hinder femora more broadly and longly above, and also broadly below, 
black ; wings hyaline, the apex tinged with fuscous, the rest more slightly 
tinged with violaceous ; the nervures black ; the basal three abscissae 
of the radius of equal length ; the basal two transverse cubital nervures 
straight, oblique, converging in front ; the third converging in front from 
below the middle, the rest rounded ; the first recurrent nervure received 
near the apex of the basal fourth of the cellule, the second at half the 
distance from the apex ; pro- and mesonotum transversely striated, the 
metanotum closely reticulated in the middle, and closely, transversely 
striated ; pleurae obscurely punctured, the lower half obscurely, obliquely
