Descri2Jtions of New Species of Parasitic Hymenoptera. 79 



radius more than twice the length of the basal two united ; the apical 

 abscissa of the cubitus not quite so long as the basal two united ; 

 both are thickened at the base. Face coarsely irregularly rugose- 

 reticulated ; a wide deep furrow on the top and a narrower one on 

 either side of the clypeus. Scape stout, densely pilose, as long as 

 the eyes. Coxal tooth stout, curved, narrowed towards the apex,, 

 projecting slightly beyond the apex of the coxae.

Black ; the metanotum, abdomen, and tegulae pale orange-yellow;, 

 the anterior wings yellowish hj^aline to the transverse median and 

 transverse basal nervures, dark fuscous beyond ; the posterior 

 hyaline, only slightly tinged with yellow, the apex smoky. $ . 



Length 10 mm. ; terebra 4 mm. 



Transvaal. 



Face coarsely, rugosely punctured-reticulated ; the top depressed 

 in the centre, with a smooth longitudinal keel ; oral region above 

 with a tuft of long testaceous hair. Front, vertex, outer orbits, and 

 malar space smooth and shining, almost bare. Pro- and mesothorax 

 smooth and shining ; the base of pronotum raised, irregularly reticu- 

 lated ; the propleurae with a wide crenulated furrow below the 

 middle ; there is an oblique, irregularly crenulated furrow below the 

 tegulae ; there is a deep, crenulated furrow above the sternum, com- 

 mencing at the base but not extending to the apex. Median seg- 

 ment strongly, closely irregularly reticulated, the pleurse more 

 strongly than the rest. Basal segment of the abdomen strongly 

 closely striated ; the second more finely striated near to the apex, 

 which is smooth, as is also the rest of the abdomen. The oval 

 transverse area on the second segment is clearly defined ; the 

 furrows are crenulated. Parapsidal furrows irregularly crenulated 

 at the apex. Apical slope of scutellum closely strongly striated. 

 Post-scutellum stoutly keeled in the middle. Basal coxal spine long, 

 curved, sharply pointed ; the lower spine much shorter, blunter, 

 roundly sloped above, the lower part straight. Apical abscissa of 

 radius longer than the basal two united ; the second cubital cellule 

 almost square, but widest at the base ; the recurrent nervure is 

 received near its apex.

Transverse median nervure placed behind the transverse basal, 

 the median cellule therefore shorter than the costal ; radial cellule
