narrowed above. Thorax closely, rugosely punctured, thickly covered 

 with white pubescence. Petiolar area large, narrowed towards the 

 apex, where it is one-third of the width of the base ; the areola large, 

 longer than wide, obliquely narrowed towards the base, which is not 

 quite half the width of the apex ; the keel on the latter is indistinct. 

 The hair on the apical slope of the median segment is longer than it 

 is on the rest of the thorax. Petiole longer than the second seg- 

 ment ; the post-petiole closely striated ; the middle of the second 

 segment is tinged with rufous. Tarsi shortly spinose ; the calcaria 

 pale, the long spur of the hinder one-third of the length of the 

 metatarsus.

Black, the thorax, post-petiole, and antenna red, as are also the 

 antennal tubercles, apex of clypeus and mandibles ; legs of a darker 

 red, the hind tibia? and tarsi black, the former with a broad white 

 band at the base ; wings hyaline, the nervures and stigma black ; 

 the tegulai, base of costa and of stigma black ; the cloud is brown, 

 commences near the middle of the stigma and extends to its apex ; 

 it is rounded behind and reaches close to the middle of the recurrent 

 nervure, there being another, fainter, smaller cloud beyond it ; there 

 is a smaller cloud behind the transverse median and the lower half 

 of the transverse basal, it being narrowed to a point along the latter. 

 The post-petiole, the second and the third segment, except at the 

 apex, are closely, strongly longitudinally striated ; the others smooth 

 and shining ; the post-petiole is broad at the apex, becoming gi-adu- 

 ally narrowed towards the base ; there is no depression on the 

 second segment ; the fifth segment has a narrow, distinct band on 

 the apex. ? . 



Length 6 mm. ; terebra 1-5 mm. 



Cape Colony. 



Thickly covered with a white pubescence. The first joint of 

 flagellv;m slightly, but distinctly, shorter than the second ; the 

 apical joints are unfortunately broken off. Head and thorax closely 

 rugosely, finely punctured ; the metanotum more coarsely than the 

 rest. Areola longer than wide ; it is broken by the lateral keel 

 shortly beyond the middle, slightly narrowed towards the base, the 

 apex closed, transverse ; petiolar area distinct ; there are eleven 

 areae, including the spiracular. 



This species comes close to ^-annulata ; it differs essentially in 

 its broader, triangular post-petiole, much longer ovipositor, and 

 shorter, broader, more ovate abdomen.
