 ft. {Neave, Nov.). 



This large species has a deceptive resemblance to T. 

 josephus Duv., which is found in the same localities and 

 of which the pattern is almost the same, although in the 

 new form the recurrent ends of the yellow elytral loop do 

 J lot always coalesce with the orange apical patch. The 

 best-marked difference is found i]i the absence of the basal 

 stria of the pronotum, but the elytra are more narrowly 

 margined, parallel-sided and convex, and the antennae in 

 both sexes are broadly truncate at the end, whereas in 

 T. josephus they are a little narrowed. The emargination 

 of the front and middle tibiae and the strong spine of the 

 middle tibia, in the male, as well as the median groove 

 upon the last ventral segment of the female are features 

 not found in T. josephus and the two tubercles at the 

 posterior margin of tlie penultimate ventral segment are 

 less widely separated than in that species. In a specimen 

 from S. Nigeria which I regard as the male of T. angolcnsis 

 Gorh., these tubercles are three in number.

Two specimens of each sex have been found. 



The species has a very close affinity to T. angolensis and T. 

 rex, but, in addition to the absence of the reddish apical 

 ])atch upon the elytra, the male is without tubercles at the 

 hinder margin of the penultimate ventral segment and the 

 female has no longitudinal groove upon the terminal 

 segment. The elytra are r9,ther more founded at the
