ABT.5 GENERIC REVISION OF THE FOSSORIAL WASPS PARKER 143 



except on the midline bears numerous coarse punctures, while those 

 at the sides are much finer. The sixth tergite is broadly rounded at 

 the apex and the sixth sternite is noncarinate. The pubescence, 

 which is short and white, is almost lacking on dorsum of thorax and 

 propodeum. 



Length 20 mm. Described from a single female bearing the label, 

 " Witu Lamu, G. Denhardt G." 



Type. — In the Zoologisches Museum der Universitat, Berlin.

To this species I have referred a single female bearing the label, 

 " D. S. W. Af rika, Lindt S." The clypeus is covered with fine, sil- 

 very pubescence. In other respects it conforms very closely to the 

 description of the species as given by Handlirsch, who reports it 

 from South Africa (Transvaal and Capeland).

Type (female). — Black: narrow fascia on posterior dorsal border 

 of pronotum, connecting large, lateral spots; tubercle and narrow 

 line rimning downward from it on side of prothorax ; narrow fascia 

 on posterior border of scutellum; fascia on metanotum; interrupted 

 fascia on dorsum of propodeum ; lateral angles of propodeum ; broad 

 fasciae on tergites 1-5, first greatly narrowed (almost interrupted) 

 at dorsal midline, second inclosing pair of elliptical, dorsal spots, 

 third strongly and fourth weakly biemarginate on anterior dorsal 

 border; small lateral spots on sternites 2-5; yellow. Clypeus, an- 

 tennae, except tips above; narrow line between antennae and pair 

 of spots above them ; three spots on f rons at level of anterior ocellus ; 

 broad anterior orbits deflected inward from eye-margins above 

 anterior ocellus ; posterior orbits ; apex of sixth tergite ; apex of sixth 

 sternite ; narrow apical lines joining yellow lateral spots on sternites 

 2-5 ; legs for the most part ; fen^ginous. The clypeus and mandibles, 

 as well as the lower part of the posterior orbits, are more yellow 

 than ferruginous. The tibiae and tarsi also show this mingling of 

 yellow and ferruginous and the femora at the base are marked with 

 black. 



The basal half of the wings is strongly infumated, whereas the 

 apical part is hyaline. The pubescence is white and comparatively 

 abundant on head, sides of thorax, and on the propodeum. On the
