 of face striated. Mandibles yellowish, the teeth black. Antennae 12- 

 joiuted, filiform, brown-black, the scape pale toward the base; first

 (Type T. claricornh Latr.) 



Head transverse, the occiput margined; ocelli 3, rather close to 

 gether in a triangle; eyes ovate. 



Antennae 12-jointed in both sexes, inserted on a clypeal prominence; 

 in S filiform, in 9 ending in a 6-jointed club. 



Maxillary palpi 4-jointed ; labial palpi 3 jointed. 



Mandibles falcate, bidentate at apex, the outer tooth long, acute. 



Thorax short, ovoid, the prothorax not visible from above; mesono- 

 tum short, broader than long, without furrows; scutellum semicircu- 

 lar; post-scutellum spined; metathorax very short, the posterior angles 

 rarely acutely toothed. 



Front wings with a linear marginal vein, rarely five times as long as 

 the short stigmal, postmarginal not developed. 



Abdomen long-oval, depressed, insert-ed far above the hind coxae, 

 the first segment longer than wide, the third the longest and widest. 



Legs slightly pilose, the posterior femora swollen, their tibiae and 

 first tarsal joint dilated, the tibial spurs distinct but short. 



The swollen hind femora, their dilated tibiic and tarsi, stronger tibial 

 spurs, and the larger mandibles can be depended upon to distinguish 

 the genus. 



The species are rare and only a few have been described that really 

 belong here.
