OXYJOPPA FLAVOBALTEATA, sp. nOV. 



Eufous ; the base of the mesonotum, the median segment, except 

 for two large marks on the sides, extending on to the pleuriB, the basal 

 three-fourths of the second abdominal segment and almost the half of 

 the third, black ; the apex of the second with a yellow band all 

 round, it being separated from the black by a red band of similar 

 size. Apical half of antennae black ; there is a yellowish band in 

 the middle. Wings hyaline, veiy weakly infuscated at the apex ; 

 the stigma fulvous. Legs dark rufous, the hind tibiae and tarsi 

 blackish. J . 



Length 13 mm. 



Natal. Estcourt. 



Face and clypeus closely punctured, covered with a short pubes- 

 cence. Front deeply depi'essed ; stoutly keeled down the middle, the 

 centre somewhat strongly transversely striated ; the vertex shining, 

 weakly punctured. Antennte short, not much longer than the head 

 and thorax united ; the third joint longer than the fourth. Thorax 

 closely rugosely punctured, the median segment more coarsely than 

 the rest ; the scutellum coarsely reticulated ; the apical slope and the 

 post-scutellum irregularly longitudinally striated, the striae twisted. 

 Upper half of propleurae closely obliquely striated, the lower closely 

 punctured ; the meso- and metapleurae closely punctured, more or 

 less reticulated. The median segment is thickly covered with white 

 pubescence. Post-scutellum deeply, sparsely punctured ; its apex is 

 obscure yellow ; the second and third segments are closely, somewhat 

 strongly punctured. Wings short, not reaching much beyond the 

 middle of the abdomen. 



Probably the amount of black on the thorax and abdomen 

 varies. 



PHAISURA, gen. nov. 



Median segment without areas, depressed at the base ; there are 

 two keels in the middle, running from the base to the apex, with 

 a curved transverse, not very distinct, keel at the top of the apical 

 slope, forming almost two keels; there is another longitudinal keel 

 along the outer edge of the metanotum ; the spiracles linear, not 

 very long, narrow. The whole segment is rugosely punctured. 

 Scutellum roundly convex, the sides stoutly keeled, the apex with 

 an oblique slope. Wings uniformly fuscous violaceous ; the areolet 

 oblique, 4-angled, the nervures uniting in front, the transverse 

 median nervure interstitial. Abdominal petiole long and slender, the
