Antals of the Transvaal Museum. 
135 
striated ; apex of clypeus bluntly rounded, the middle almost transverse ; 
hinder ocelli separated from each other by almost half the distance they 
are from the eyes. M°le. 
Length, 18 mm. 
Berea Park. December. 
The third antennal joint almost as long as the following two united ; 
the metanotal area becomes gradually roundly narrowed to a sharp point 
from the spiracles. 
Ammophila caeruleornata, sp. n. 
Black ; the third and following segments of the abdomen blue ; the 
mandibles, except the teeth, the propleurae, the sides of the pronotum, 
the mark narrower than the central black part, and the tegulae, red ; the 
legs, with the coxae, four anterior trochanters, femora, and tibiae, of a 
darker red ; wings hyaline, tinged with violaceous ; the costa and nervures 
testaceous ; the basal two abscissae of the radius equal in length, the 
third very slightly longer ; the basal two transverse cubital nervures 
straight, oblique, converging in front, the third broadly, roundly curved ; 
the first recurrent nervure received at the apex of the basal fourth, the 
second nearer the apex of the cellule. Male. 
Length, 16 mm. 
Berea Park. December. 
The silvery pubescence dense ; the hair on the front, vertex, outer 
orbits, and pleurae long and dense ; eyes distinctly converging below ; 
the hind ocelli separated from the eyes by a distinctly greater distance 
than they are from each other; pro-, meso-, and metanotum somewhat 
strongly, transversely striated, the mesonotum not quite so strongly as 
the rest ; the scutellum more strongly and not quite so closely longitu- 
dinally striated ; the post-scutellum finely rugose, irregularly, longitu- 
dinally striated. 
Ammophila dolichocephala, sp. n. 
Black, densely covered with a silvery pile ; the under side of antennal 
scape, mandibles to the teeth, pronotum, and tegulae, red ; the first 
abdominal segment, the sides, ventral segment, and apex narrowly of the 
second, the third, the sides of the fourth and following segments and the 
ventral surface, the legs except the coxae, trochanters, and the femora 
to near the apex, of a more ferruginous red ; the apical three joints of the 
four anterior tarsi and the hinder, except the basal joint and the base of 
the second, black ; wings hyaline, slightly tinged with violaceous and 
fulvous ; the stigma and nervures black ; the first abscissa of the radius 
slightly longer than the second, which is four times longer than the third ; 
the first recurrent nervure is received at the apex of the basal fourth, the 
second nearer the apex than it ; the second transverse cubital nervure is 
straight ; the third roundly obliquely turned towards its fore part ; pro- 
notum smooth, a little longer than it is wide at the apex ; the narrowed 
basal part two-thirds of the length of the apical ; metanotum irregularly, not 
very strongly punctured ; a smooth space on either side of the apex ; the 
sides from the tegulae irregularly, transversely striated ; there is a narrow 
but distinct furrow down the centre, from the base to shortly beyond the
