Mr. R. E. Turner on Fossorial Hymenoptera. 45 



c? . Clypeus short and broad, very broadly rounded at the 

 apex, closely punctured-rugulose and clothed with whitish 

 hairs. Head closely and strongly punctured, the front rugose, 

 interantennal prominence strongly raised, broad and emar- 

 ginate at the apex. Antennae moderately stout, about 7 mm. 

 in length, third and fourth joints of the flagellum sub-equal, 

 each at least half as long again as the second, the first almost 

 concealed, the four subapical joints feebly arcuate beneath. 

 Eyes shallowly emarginate on the middle of the inner margin. 

 Thorax closely and not very coarsely punctured ; pronotum 

 as long as the scutellum, feebly narrowed anteriorly. Median 

 segment very closely and rather strongly punctured-rugose, 

 the whole thorax and median segment clothed with whitish 

 hairs, very sparsely on the dorsal surface, more closely on 

 the sides. Abdomen shallowly, but not very finely punc- 

 tured ; the petiole of the first segment half as long as its 

 strongly broadened apical portion, second segment as long as 

 the first without the petiole, nearly twice as broad at the apex 

 as at the base, the third segment the broadest. Seventh 

 tergite longitudinally striated, the apex smooth, with a deep 

 but very narrow apical slit ; hypopygium forming the usual 

 recurved aculeus, but shorter than in most species of the 

 genus. Hind tibiae serrate. Third abscissa of the radius a 

 little longer than the second, much longer than the fourth. 



Hab. Kraaifontein, Cape Colony (Lightfoot) . 



Type in the South African Museum. 



A rather aberrant species in the fusiform shape of the 

 abdomen, and in the sculpture and apical slit of the seventh 

 tergite.

$. Viridi-ceerulea ; mandibulis, palpis, flagello articulis 3-11, 

 secundoque apice, tarsisque articulis duobus apicalibus nigris ; 

 alis fusco-hyalinis, fusco obscure bifasciatis.

Long., $ 20 mm., <5 13 mm. 



$ . Carina of the clypeus produced into a short blunt tooth 

 at the apex, with a blunt tooth on each side. Head produced 

 and strongly narrowed behind the eyes ; the frontal carinas 

 prominent, not nearly reaching the level of the anterior 

 ocellus ; vertex coarsely punctured, with distinct transverse
