irregularly striated ; the second and third closely, strongly, rugosely 

 reticulated; the fourth and fifth longitudinally rugosely striated; the 

 seventh and eighth smooth. 



The middle of the front is finely closely punctured ; there is a 

 keel, margined on the top down the middle. First abscissa of the 

 radius two-thirds of the length of the first transverse cubital nervure ; 

 the second half the length of the third ; the second cubital cellule 

 twice longer than v/ide ; the recurrent nervure is received close to 

 the apex of the first cubital cellule. Antennae stout, shorter than the 

 abdomen. Plate on second abdominal segment smooth, broader than 

 long, narrowed to a sharp point. 



Length 19 mm. ; terebra 55 mm. 



Southern Ehodesia. Sebakwe. 



■'■ Bacuma fumipennis, sp. nov. 



Black, face, clypeus, malar space, base of mandibles broadly, 

 upper inner orbits narrowly, the greater part of prothorax, base of 

 metanotum narrowly, its apex in the centre broadly, a streak along 

 the edge of the mesosternum, the basal four abdominal segments, a 

 narrow line on the apex of the fifth and the apical one, rufo-testa- 

 ceous ; antennse fuscous towards the apex ; wings smoky ; the first 

 cubital cellule and the apex, before and behind, more hyaline ; costa, 

 nervures and apical half of stigma blackish ; the basal half of stigma* 

 pale ochraceous. $ . 



Length 11 mm. ; terebra 15 mm. 



Cape Colony. 



Face closely, irregularly reticulated, covered with black hair ; there 

 is a narrow black streak down the middle ; the rest of the head 

 smooth and shining, as is also the thorax. Parapsidal furrows 

 distinct. First abdominal segment smooth, the apex of middle lobe 

 laterally irregularly striated ; the second, third, and fourth segments 

 are coarsely, irregularly punctured-reticulated ; the fifth and sixth 

 are similarly, but more weakly, punctured-reticulated-striated; the 

 rest smooth. The basal area on the second segment is wider than 

 long, gradually narrowed to a blunt point. The alar nervures are as 

 in the preceding species. The hypopygium is not prominent, not 

 projecting beyond the apex of the dorsal segments ; it is testaceous, 

 streaked with black. The anterior two legs testaceous, the middle 

 testaceous, the coxae and under side of the femora black ; the 

 hind pair black, apex of trochanters, of femora and the tarsi 

 testaceous.
