the whole pedicel, is black ; the clypeus is tri-dentate in front, but 

 the angle of the lateral sinuation is rounded, the clypeal keel reaches 

 the sides; the shape of the prothorax is the same as in A. ditis- 

 simus, but the punctuation of that part and also of the head is 

 neither so deep nor so rugose ; the sharply ogival scutellum is also 

 sparingly punctured ; the elytra have only three, or at most four, 

 plain striae, and the punctuation of the intervals, as well as of the 

 sides, is deep, but not as much as in A. ditissimus, and the under 

 side is alike, but the anterior tibiae are bi- instead of tri-dentate 

 outwardly ; in the male the tubular part of the armature is notched 

 in the centre and on each side, and the two forcipate processes are 

 symmetrical, long, slender, and curve upwards at the tip. 



Length 7-8 mm. ; width 5-5 J mm.

Very dark bronze with a moderate sheen {T. crassus, T. moerens, 

 T. moestus), or with the elytra bronze-red and a bright sheen 

 (T. interpunctatus), completely reddish on the upper side (T. 

 vagans), or lastly with a fuscous, longitudinal patch on each 

 elytron (T. plagiatus) ; pedicel of antennae rufescent, the club, 

 which in the male is slightly longer than the pedicel, is black 

 or darkly infuscate ; it is a little more parallel than A. pavoninus 

 and plainly less convex, but the shape of the head and prothorax, 

 and also the sculpture, are as in A. pavoninus, while in general 

 appearance it more resembles A. ditissimus, but it is not quite so 

 massive ; the elytra have the four dorsal striae very distinct, but the 

 sides are also fairly distinctly striate ; the anterior tibiae are tri- 

 denta *, and the under side is similar to that of the other species 

 above mentioned, but the shape of the genital armature is very 

 different, the forcipate processes cross each other at about half the 

 length, the left one is slender and cylindrical, the other thickly 

 spatulate at the apex. 



Length 6-7 J mm. ; width 4-4|- mm. 



Hab. Southern Ehodesia (Victoria Falls), Ovampoland.
