Type in British Museum. 



The single specimen was obtained in Central or Eastern Somali- 

 land (1S97). This species is allied to T. denticidatu* Oliv., which 

 also occurs in Somaliland, but it is considerably larger and relatively 

 broader, the widely dilated margins of the elytra making their 

 outline almost circular. The elytral costae consist of irregular . 

 tubercles which are separate at the base, more or less confluent 

 on the disc, and small and scattered towards the apex ; the alter- 

 nate rows only of these reach the basal margins of the elytra. 

 The anterior tibia is armed with four acute teeth placed at right 

 augles to its axis and regularly increasing in size towards its 

 extremity, the last being very sharp and prominent. T.funeetua 

 Lansb.. a \V. African species, appears to be nearly related to this 

 insect, but is smaller and narrower, T. exponents being one of the 

 largest at present known in the genus.
