Black ; the mandibles, the scape of the anteiinoe at the 

 apex, the flagellum more distinctly beneath than above, the

 extreme apex of the pronotum, of the tegulte, and of the 

 abdominal segments testaceous; the pubescence whitish.

Near T. natalensi's, Sm., from whicli it may be distiiiguislied 

 by the longer tegula?, the smaller stigma, the sculpture of

? . Clypeus very delicately punctured ; the head rather 

 coarsely, but not veiy closely punctured, least closely round 

 the ocelli. Pronotum rather coarsely and very closely 

 punctured, the posterior margin narrowly smooth and shining ; 

 the propleuras finely striated, smooth and shining at the 

 summit ; the mesopleurse closely, but not very coarsely 

 punctured ; mesonotum and scutellum punctured, the punc- 

 tures larger and more scattered than on the pronotum. 

 Median segment sliort and broad, opaque and finely rugulose, 

 the median carina reaching the apex, the two outer carinas 

 rather far apart, converging slightly towards the apex, the 

 distance between them at the apex about three-quarters of 

 that at the base ; the sides of the segment obliquely striated. 

 Tegular closely punctured, the extreme apex smooth and 

 shining. Abdomen shining, closely punctured, the two basal 

 segments a little more sparsely than the others, the basal 

 segment very abruptly truncate at the base, rather strongly 

 constricted at the apex, tlie apical margin of all the segments 

 very narrowly smooth. Epipygiura longitudinally punctured 

 rugose, the apex broadly smooth and shining. The stigma 

 is large and the radial cell very broad.
