hyaline, the apex slightly tinged with fulvous ; the stigma and the 

 costa in front fulvous, the nervures darker. <J . 



Length 10 mm. 



Cape Colony. 



AntenniB short, as long as the ahdomen, the scape black above ; 

 the apical joints serrate. Face and clypeus closely, strongly punc- 

 tured, thickly covered with pale fuscous pubescence ; the front and 

 vertex are more closely and as strongly punctured. Temples wide, 

 obliquely, roundly narrowed, thickly covered with long white pubes- 

 cence. Apical joint of mandibles long, the sub-apical short. Pro- 

 and mesothorax closely punctured ; the scutellum rounded, not fiat, 

 shining, sparsely punctured and haired. Post-scutellum closely 

 rugosely punctured. Median segment short, its base obliquely 

 depressed, the areola large, longer than broad, transverse at the 

 base and apex ; longitudinally rugose-striated ; the rest of the 

 segment is closely rugosely punctured ; the keels appear indistinct 

 owing to the roughness of the sculpture ; the basal arese are sepa- 

 rated ; the keel bounding the outer side of the spiracular area is 

 distinct only on the base. The raised central lobe of the post-petiole 

 bears some large, clearly separated punctures, as do also the sides at 

 the apex ; the other segments are punctured, the punctuation becom- 

 ing weaker towards the apex ; gastrocoeli large, deep in the centre, 

 the sides stoutly striated ; there are seven segments ; the penulti- 

 mate bears two large, greenish-yellow marks above ; the ventral keel 

 extends to the apex of the fourth segment ; the last ventral becomes 

 gradually narrowed to a point. Areolet 5-angled, the recurrent 

 nervure is received shortly beyond the middle ; the transverse 

 median nervure beyond the transverse basal ; the disco-cubital 

 nervure is broken by a short stump. Apex of hind tibxse black ; 

 the apices of tarsal joints blackish. Spiracles of median segment 

 about three times longer than wide. 



LEPTOPHATNUS, gen. nov. 



Wings uniformly dark violaceous ; the areolet 4-angled, the trans- 

 verse cubital nervures meeting in front ; the disco-cubital nervure 

 broken by a stump of a nervure ; the transverse median nervure 

 interstitial. Antennae dilated beyond the middle. Metanotum 

 regularly ai-eolated ; in the middle is a long narrow area extending 

 from the base to the base of the apical third, the apex being 

 narrowed ; on either side of it are two large areas, the basal one 

 longer than wide, of equal width, the apical is longer on the outer
