spines rather long and very acute. First node subcubical, longer 

 than broad, convex above, where it is scarcely broader posteriorly than 

 in front, with a petiole anteriorly nearly as long as itself. Second 

 node rounded, slightly broader than long and broader than the first 

 node. Pilosity very fine, short, moderately abundant on the body, 

 very oblique on the tibiae and tarsi. Head coarsely striate, with 

 reticulations between the striae, finely reticulated at bottom and 

 subopaque in front. Thorax coarsely but superficially reticulate, 

 with thestriae on the middle of the mesonotum and the sides smooth. 

 Sloping face of the metanotum between the two carinse connecting 

 the bases of the metanotal and metasternal spines, finely reticulate, 

 also the sides of the nodes. The rest smooth and shining. 

 Eeddish ferruginous ; legs, antennae and spines yellowish.

. Head, thorax and pedicel dull ferruginous red ; abdomen 

 brown, paling at the extreme base and on the 2nd and following 

 segments, the apical margins of the abdominal segments yellowish; 

 mandibles, antennae and legs reddish yellow ; head longitudinally 

 striate, with some fine reticulations between the striae ; thorax 

 and nodes of the pedicel somewhat coarsely reticulate and rugose ; 

 abdomen smooth, polished and shining, with vestiges of minute 

 longitudinal striae at the extreme base : pilosity pale yellow, fine 

 and fairly abundant, especially on the front of the head, oblique 

 and very short on the scape of the antenna? and the tibiae. Head 

 without the mandibles rectangular, half as long again as broad ; 

 mandibles as in T. scabrum but slightly narrower, smooth, slightly 

 minutely punctured but not striate ; clypeus longitudinally 

 bicarinate in the middle, broad and somewhat convex ; antenual 

 carinae wide apart and produced slightly divergently back nearly to 

 the top of the head, bordering a well-marked antennal groove, 

 which is sculptured within like the rest of the head; antenna 

 stouter than but similar to those in T. scabrum ; eyes placed in the 

 middle of the sides of the head. Thorax broader anteriorly than 

 in T. scabrum, the sides vertical, margined above ; pro-mesonotal 

 suture obsolete, but in all specimens I have seen the pronotum is 

 crossed by a distinct fine transverse carina ; meso-metanotal suture 

 moderately distinct above the thorax, incised at the sides at the 

 suture ; basal portion of metanotum narrow, short, the posterior 

 lateral angles furnished with moderately long, stout, oblique spines 

 which are divergent and curved outwards at the apex. Pedicel 

 rather short, with large nodes ; the 1st node anteriorly petiolate, its 

 face somewhat curved inwards, posteriorly rouudly sloped ; 2nd 

 node seen from above transversely globose, a little broader than
