Black, shining ; epistoma with two deep impressions, a lateral 

 and a median one, on each side ; head with a deep impression in the 

 anterior part, posterior part of the head and neck faintly plicate ; 

 prothorax as broad at its widest as long, hexagonal, but with the 

 median part somew^hat rounded, outer angles recurved, disk covered 

 with dense, irregular punctures, often confluent, and the intervals of 

 which are slightly raised ; elytra elongato- ovate, very convex, 

 acutely carinate, carinae smooth, the intervals broad and filled with 

 a double series of subtuberculated punctures ; legs long ; under 

 side smooth. Length 40-45 mm. ; width 15-16 mm. 



This species is closely allied to T. Megerlei, from Calabar ; but the 

 outer sides of the prothorax are more diagonal from the apex to the 

 middle and from the middle to the base, and also much less scrobicu- 

 late than in Megerlei. ,

Shape and colouring of T. Delegorguei and Megerlei; head with 

 two deep impressions on the epistoma and two deeper ones on the 

 vertex over the eyes, posterior part and neck not plicate ; prothorax 

 about one-fifth broader than long, gradually ampliated from the 

 anterior angle to two-thirds of the length, with the posterior part 

 slightly sinuate, and subdiagonal, disk slightly rugose ; elytra 

 elongato-ovate, very convex, broadly carinate with the intervals 

 broad and filled with a double series of tuberculated punctures. 

 Length 50 mm. ; width 21 mm. 



More closely allied to T. Megerlei than to Delegorguei, this species 

 differs from the latter in the shape of the prothorax which is not sub- 

 hexagonal, but gradually ampliated laterally from the apex to past 

 the median part, and with the angular part almost rounded (while
