Some New Genera arid Species of Hymcnoptera. 215 



rufous ; the spines on the fore tarsi are slender, as long as the apical 

 joint, and apparently few in number. Mandibles on lower side, 

 behind the incision, broad, transverse. Malar space obsolete. Fore 

 ocelli separated from the posterior three times the distance these are 

 from each other. Median segment clearly longer than it is wide at 

 the base, narrowed towards the apex. There is no depression or 

 furrow on the vertex behind the ocelli.

Gen. CERCERIS, Latr., 

 Cerceeis holconota, sp. nov. 



Black ; clypeus, the inner orbits to the base of antennae, the spot 

 obliquely narrowed above, cheeks, a conical spot — the rounded part 

 above — below the antennal keel, the basal half of mandibles, a spot 

 on either side of pronotum, an almost interrupted line on post- 

 scutellum, a line, narrowed in the middle on the apex of the third 

 abdominal segment and one of equal width on the apex of the fifth, 

 pale yellow. Legs bright red, the hind coxae black, the tibiae yellow 

 on the outer side. Antennal flagellum fulvous, darker above. 

 Wings hyaline, the apical half suffused with smoky tints ; the costa 

 and stigma dark testaceous, the nervures black. 5 . 



Length 11 mm. 



Cape Colony. Dunbrody. 



Metanotal area smooth, shining, deeply furrowed in the centre ; 

 the apical slope also deeply furrowed. Clypeus flat, its apex broad, 

 transverse, depressed, black. Third joint of antennae slightly shorter 

 than the first and longer than the fourth. Hinder ocelli separated 

 from each other by about the same distance as they are from the 

 eyes. Front and vertex strongly and closely, the face and clypeus 

 more sparsely punctured. Front with a keel in the centre. Pro- 

 and meso-notum strongly but not closely punctured ; the latter 

 broadly depressed in the centre of the basal half, the pleurae more 

 coarsely, closely, rugosely punctured. Abdomen strongly punc- 

 tured ; the pygidium opaque, granular, the base with some irregular 

 punctures ; more narrowed towards the base than to the apex ; 

 incision in epipygium reaching to the middle ; the penultimate seg- 

 ment broadly raised in the middle, rugose, projecting laterally at the 

 apex and densely covered with white pubescence. The third ven- 

 tral segment marked with white, narrowly in the middle, broadly 

 laterally.
