. Head, thorax and pedicel brownish red (sometimes the head 

 dark brown or blackish), abdomen dark brown, almost black, legs 

 more or less brownish yellow ; head striate, reticulate between 

 the stria?, especially posteriorly, thorax coarsely punctured and 

 reticulate, longitudinally finely striate on the sides ; nodes of 

 pedicel punctured, opaque ; abdomen smooth, polished and shining ; 

 pilosity pale, fairly abundant, especially on the head in front, on 

 the antenna? and the tibiae of the legs it is a little oblique. Head 

 without the mandibles a little longer than broad, the sides convex, 

 the head seen from the front posteriorly transverse ; mandibles 

 densely finely longitudinally striate, with a few small punctures 

 interspersed ; clypeus proportionately rather large, very convex, 

 anteriorly transverse, its posterior margin well-defined, feebly- 

 arched between the bases of the antennae ; antennal carinae wide 

 apart, produced back as stria? bordering the space for the reception 

 of the antenna?, which is not furrowed or grooved in any way ; 

 antenna? short and thick, but longer than in T. inglebyi, Forel, the 

 scape reaching to about a quarter of its own length to the top of 

 the head ; eyes placed rather below the middle on the sides of the 

 head. Thorax broad behind, sloping posteriorly and narrowly from 

 the pronotum to the apex of the metanotum ; sutures obsolete, 

 no emargination ; metanotal spines moderately short, thick and 

 stout, somewhat wide apart. Pedicel : the 1st node longer than 

 broad, rounded above, constricted in front and shortly petiolate ; 

 2nd node semicircular posteriorly, transverse anteriorly, broader 

 than the 1st node; abdomen oval, convex, broader in front than 

 posteriorly.

Reddish or ferruginous yellow, the legs and abdomen a 

 shade paler ; head with some light longitudinal fine stria? wide 

 apart from each other, closer on the anterior portion of the head, 

 the disc of the thorax also with a few vague half-obsolete longitu- 

 dinal striae ; the rest of the insect smooth and shining ; pilosity 

 rather sparse, the hairs very short and obtuse at apex, most 

 plentiful on the scape of the antenna? and tibia? of the legs. Head 

 very short, a little broader posterior)} than in front, the cheeks 

 very convex ; mandibles slightly longitudinally striate ; clypeus 

 truncate and transverse anteriorly ; antennal carina? short, not 

 produced backwards, no antennal furrows; antennae short, the 

 scape not reaching the top of the head by about one-third of its own 

 length ; eyes prominent, rather large, placed a little below the 

 middle of the sides of the head. Thorax short, in profile appear- 

 ing strongly arched from front to back ; meso-metanotal suture
