Some New Genera and Species of Hymenoptera. 231 



segment (including the pleurae) alutaceous and thickly covered with 

 silvery pubescence. Tegulae large, conchiform, longer than broad. 

 Abdominal petiole as long as the thorax. First transverse cubital 

 nervure oblique, roundly curved downwards, the second not oblique, 

 roundly curved outwardly ; the third straight ; the first and second 

 transverse cubital nervures almost touching in front ; second recur- 

 rent nervure received near the apex of the cellule. 



In S. natalensis the second cubital cellule is clearly appendiculated. 



Gen. EHAPHIGLOSSA, Saunders, 

 Ehaphiglossa flavo-ornata, sp. nov. 



Black; a curved line on the top of the clypeus, a spot on the inner 

 side of the eye incision, a line on the under side of the antennal 

 scape, a line on the apex of the pronotum, a small mark, longer than 

 broad, on the scutellum on the sides, two large lines on the post- 

 scutellum, two oblique marks on the apex of the metanotum, two 

 triangular marks on the apex of the first abdominal segment, a 

 narrow line on the apex of the second, lines in the centre of the 

 following three at the apex and a somewhat triangular mark (the 

 broad end at the base) on the last, pale yellow ; two small reddish- 

 yellow marks on the vertex above the antennae ; a broad rufous 

 mark on the vertex behind, broad above, below reaching to the end 

 of the eyes, becoming narrowed gradually below ; the sides of the 

 propleurae narrowly above, the apex and middle broadly and a line 

 behind the middle of the abdominal petiole red. Legs of a brighter 

 red colour, the fore coxae black ; the tibiae pale yellow on the outer 

 side, the hind tarsi infuscated. Wings fuscous-violaceous, the stigma 

 and nervures black. Basal half of antennae red. Basal half of 

 mandibles red on the inner side. ? . 



Length 15 mm. 



Cape Colony. Dunbrody. 



Head closely and strongly punctured, more closely on the front 

 than elsewhere ; covered with a white down. Apex of clypeus 

 almost transverse in the middle, the sides projecting into large leaf- 

 like expansions, roundly curved on the outer side, narrowed towards 

 the apex, the outer border raised, the inner side straight. Thorax 

 closely, rugosely punctured ; the centre of the metanotum almost 

 smooth, keeled down the middle. Metapleurae sparsely punctured 

 behind the middle and at the apex. Abdominal petiole faintly punc- 

 tured, the other segments smooth and covered with a white pile. 

 Petiole longer than the other segments united. 



This species cannot well be confounded with B. natalensis, Sm.
