Type in B.M. ex coll. Turner. 



Closely resembling T. rufipes^ Guer., in size and colour, 

 but Guerin gives the abdomen as "simple en arri^.e," which 

 could not be applied to the peculiarly shaped hypopygium of 

 this species.

cJ . Mandibles bidentate, the outer tooth long and acute, 

 the inner tooth short and broadly truncate. Clypeus very 

 narrowly emarginate in the middle of the apical margin, the 

 angles of the emargination produced into short spines ; a 

 caiina from the base produced anteriorly into an acute 

 tubercle overarching the base of the emargination. Antenna; 

 inserted a little lurther from each other than from the eyes, 

 rather short, not longer than the thorax and median segment 

 combined, the apical joints arcuate ; the front between the 

 antennae bilobed, with a delicate longitudinal carina almost 

 reaching the anterior ocellus. Head and thorax very closely 

 punctured, the pronotum and scutellum more sparsely, the 

 mesonotum with two longitudinal sulci on each side; median 

 segment as long as broad, with a shallow longitudinal sulcus 

 from the base to the middle, closely punctured. Abdomen 

 elongate, narrow at the base, closely punctured, the segments 

 narrowly depressed and smooth at tlie apex ; the basal seg-

 sulcus from the base to beyond the middle. Hypopygium
