Clypeus broad, convex in the middle. Frontal area not clearly denned 

 posteriorly. Frontal carinae wide apart, fairly short. Eyes prominent 

 and convex. Pro-mesouotal suture feeble or obsolete ; meso-epinotal 

 suture deep ; the thorax more or less constricted or excised laterally at 

 the suture. Ventral anterior angles of the pronotum produced into 

 distinct spines or teeth. Scutellar portion of mesonotum with an 

 elongate tubercle or carina on each side. The epinotum armed with 

 two long and acute spines ; sometimes also with the base expanded or 

 lobate on each side. First joint of petiole with a long peduncle, dis- 

 tinctly delimited from the node. Both nodes usually more or less 

 conical, the 1st often compressed laterally at the summit. Abdomen 

 subglobose ; somewhat truncate at the base. Legs long and slender. 



? . Antennae 7- jointed. Ocelli small. Thorax very gibbous and 

 convex in front. Pronotum very slightly exposed above at the sides 

 only. The level of the dorsum of the mesonotum and scutellum much 

 higher than that of the epinotum. Mesonotum and epinotum simple, 

 without lateral carinae or lobes. The dorsum of the epinotum short, 

 much shorter than the declivity ; epinotal spines much shorter and 

 broader than in the <J . Petiole as in the $ . Abdomen subovate, 

 longer than wide, truncate at the base. Wings with 1 cubital and 

 1 discoidal cell ; radial cell open. 



c? . Antennae 13- jointed, filiform. The scape short, usually about 

 as long as the 2nd joint of the flagellum ; 1st joint very short, all the 

 remaining joints much longer than wide. Head transverse. Eyes 

 large. Ocelli fairly large, slightly raised. Frontal carinae moderately 

 distinct and short. Clypeus convex. Mandibles small and edentate. 

 Dorsum of epinotum bituberculate at the apex. Petiole very long, 

 the 1st joint with the peduncle shorter and broader than in the ? , 

 both nodes flatter and elongate, not conical. Abdomen broad, cordate, 

 hardly longer than wide, convex above, concave below. Legs long and
