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- 
sumus, 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 striz, and the punctuation of the intervals, as well as of the 
sides, is deep, but not as much as in 4. ditissimus, and the under 
side is alike, but the anterior tibize 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 5-54 mm.

Very dark bronze with a moderate sheen (7. crassus, T. moerens, 
T. moestus), or with the elytra bronze-red and a bright sheen 
(TI. interpunctatus), completely reddish on the upper side (7. 
vagans), or lastly with a fuscous, longitudinal patch on each 
elytron (ZT. plagiatus); pedicel of antennz 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 dA. pavoninus 
and plainly less convex, but the shape of the head and prothorax, 
and also the sculpture, are as in dA. pavoninus, while in general 
appearance it more resembles 4. ditiss¢mus, but it is not quite so 
massive; the elytra have the four dorsal striz very distinct, but the 
sides are also fairly distinctly striate; the anterior tibixw are tri- 
dentate, 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 6-74 mm. ; width 4—44 mm.
