PHYTOPHAGOUS AND PARASITIC HYMENOPTERA. 117 



Head closely rugose; the vertex closely striated in the centre, 

 closely covered with white pubescence ; the centre of the face 

 roundly tuberculate. Mesonotum very finely and closely transverse- 

 ly striated; the furrows crenulated. Metanotum closely rugosely 

 reticulated, the basal central area is wide at the base, becomes 

 gradually narrowed to the apex , where the keels almost unite ; the 

 areola is open at the apex, being continuous with the posterior 

 median area ; the lateral basal areas are large and of equal width. 

 Except at the apex the basal three abdominal and the basal half of 

 the fourth segments are closely, regularly, finely, longitudinally 

 striated. 



This is a larger and stouter species than B. nibriornatus ; the 

 abdominal segments are closely longitudinally striated, the metano- 

 tum less regularly areolated, there being no regularly defined areola, 

 and the face is more distinctly tuberculated in the centre. 



Clitiga, gen. no v. 



6. Antennae as long as the body, 26- jointed, the first joint 

 of the flagellum longer than the second. Parapsidal furrows indicated 

 at base only. Scutellum lateralh^ stoutly keeled to near the apex. 

 Median segment short, smooth, and shining, the apex with a straight, 

 steep slope ; completely areolated, the areola wider than long, 

 rounded behind, transverse at the apex ; there are five arese on the 

 apex ; spiracles small, oval ; the sides at the apex toothed. Meso- 

 pleurse largely, deeply excavated in the centre. Areolet 5-angled, 

 the apical nervure faint, but distinct ; disco-cubital nervure rounded, 

 not angled or broken ; the transverse median nervure received 

 beyond the transverse basal ; transverse median nervure in hind 

 wings broken below the middle. First abdominal segment greatly 

 dilated at the apex, the base stoutly, angularly projecting ; the base 

 of second segment depressed, the apex of the depression transverse, 

 clearly separated. Legs moderately stout. Face flat, not separated 

 from the clypeus, which is transverse at the apex. Mandibles with 

 a long apical and a short sub-apical tooth. 



? Antennae stout, dilated towards the apex, longer than the body, 

 the basal joints of flagellum elongated. The post-petiole is not so 

 markedly tuberculated on the sides ; the apex of the abdomen is 

 bluntly pointed ; the ovipositor projects and has stout sheaths. 

 The areola is not wider than long, as it is in the 6 I have described, 

 it being nearly as long as wide ; the base of the second abdominal 

 segment is not tuberculate laterally, but it is depressed at the base, 

 as in the ■* . The abdomon i-? ^hort. bluntly pointed at tlio apex.
