 smooth. Erect pilosity moderately abundant, on the body fine, the 

 hairs pointed, rather long. The tibiae of the legs and the scape of

 smooth, polished and shining, a few light half-obsolete striae on 

 the front below the vertex and on the cheeks and the metathorax 

 above, the sides minutely rugulose ; pilosity pale yellow, some- 

 what sparse, the hairs obtuse at apex ; on the scape of the 

 antennae and on the tibia3 of the legs it is a little more plentiful 

 and much shorter. Head without the mandibles, seen from the 

 front, almost square, as broad as long, posteriorly appearing 

 transverse ; mandibles finely longitudinally striate, much as in 

 T. christiei ; clypeus broad and convex anteriorly, bent down with

defined ; antennal carinae short, not prolonged back as in 

 T. christiei, no antennal groove, but the place where the scape 

 rests, inwards from the eye, very minutely rugulose, but shining not 

 opaque ; antennae somewhat short, the scape not quite extending 

 to the top of the head ; eyes lateral, very little below the middle 

 of the head. Thorax convex, narrow, the pro-mesonotal suture 

 obsolete, the meso-metanotal suture distinct, the basal portion 

 of the metanotum curved a little from front to back, the posterior 

 lateral angles without spines, barely subdentate. Pedicel pro- 

 portionately shorter than in T. christiei, with the nodes distinctly 

 higher and larger ; the 1st node rounded, with a short petiole ante- 

 riorly ; the 2nd node seen from above transverse, broader than long ; 

 abdomen broadly oval, the sides only slightly convex.
