Mentum elongated, sub-parallel, slightly sinuate in the anterior 

 part, the outer angles of which are moderately rounded ; inner lobe 

 of maxillae simple, upper lobe with a minute tooth ; clypeus a little 

 attenuate towards the anterior part, carinate laterally and with the 

 apical margin slightly reflexed ; antennal club as long as the pedicel 

 in the male ; prothorax and elytra depressed, the former moderately 

 or strongly arcuate above the scutellum, the latter with two dorsal 

 costae and with series of elongated, strongly cicatricose punctures 

 which, in the dorsal part, end towards the apex in geminate striate 

 rows ; sternal process projecting much beyond the coxae, arcuately 

 ampliate, and with a distinct transverse suture separating the meso- 

 sternal from the metasternal parts ; anterior tibiae tri-dentate out- 

 wardly, the upper tooth reduced to a moderately distinct sinuation 

 in the $ ; intermediate and posterior tibiae very plainly dentate on 

 the upper side ; tarsi moderately long, the two basal ones of the 

 posterior legs triangular, the first one plainly acuminate outwardly 

 in the $ , sub-spinose in the ? , upper and under sides glabrous, the 

 latter part roughly cicatricose punctate on the pectus and the lateral 

 part of abdomen. 



The genus is represented in East Central Africa and Senegambia. 

 One of the South African species (T. dichroa) ranges from Natal to 

 the Lake Nyanza, and the livery of the other species (T. collaris) is 

 very variable, and has led to the description as new species of colour 

 varieties.
