Descriptions of Species of Parasitic Hyvienoptera. 217 



Length 7 mm. ; terebra 3 m. 



Cape Colony. Dunbrody. * 



Head reticulated-punctured, covered with short, white pubescence. 

 Frontal depression strongly, closely, transversely striated ; there is a 

 longitudinal fine keel down the lower half. Thorax closely, rugosely 

 reticulated ; the apex of pronotum and the scutellum much more 

 strongly than the rest ; the apical slope of the scutellum stoutly, 

 longitudinally striated ; its middle projects into a stout tooth. 

 Metanotum longitudinally reticulated, the transverse keels weaker 

 than the longitudinal ones; the lateral tooth is large, blunt. Pleurae 

 closely reticulated ; the propleuraB more distinctly and less coarsely 

 rugosely than the rest. Abdomen closely, distinctly punctured 

 throughout ; there is a broad, dense belt of fulvous pubescence on 

 the third segment ; the apical segments are more coarsely, closely 

 punctured than the others ; the apical spine is longish, gradually 

 narrowed to a sharp point ; the base of the ovipositor is punctured. 

 At the base of the hind femora are two large, sharply-pointed teeth, 

 widely separated ; these are followed by at least nine short, 

 blunt ones. 



Cratocentrus bicornutus, sp. nov. 



Black ; the antennae, except the apical three joints, the greater 

 part of the head, thorax, legs, and the apices of the basal three 

 abdominal segments, rufous ; hind femora with about fifteen minute 

 teeth, forming a serrated edge ; the terminal tooth is much larger 

 than the rest ; the vertex behind the ocelli armed with two stout, 

 sharp-pointed teeth; wings hyaline, the apex with a smoky 

 cloud. (? . 



Length 9 mm. ; terebra 4 mm. 



Southern Ehodesia. Sebakwe. 



Antennae ten-jointed, almost bare. Head rugosely punctured, 

 sparsely covered with silvery pubescence; the frontal depression 

 deep, closely striated ; the sides keeled. Malar space two-thirds of 

 the length of the eyes ; there is an oblique keel near its top. 

 Thorax closely rugosely punctured ; the top of the basal slope of 

 the pronotum has an irregular, rugose keel. Scutellum rugosely 

 reticulated ; its apex rounded, depressed, striated ; the middle 

 projecting into a triangular tooth. Metanotum short, the sides 

 above projecting into stout triangular teeth. Mesopleural depression 

 deep, closely striated at the bottom. Abdomen closely and strongly 

 punctured, the apical segments more strongly than the basal ; it ig
