Allied to T. curtulus, Moraw. (R. Amur), differing 
cliiefly in the black elytra. The head is small and smooth. 
The thorax is about half the -width of the elytra, mode- 
rately and regularly rounded on the sides, a little more 
narrowed behind than before, and Avith rounded hind 
angles ; the basal foveas are large and rather deep, coarsely 
but sparsely punctured ; the reflexed lateral margins arc 
translucent pitchy-red. The elytra are oblong-ovate, 
widened behind, obli([uely sinuate near the apex ; the sur- 
face is shining pitchy-black, with a slight bronzy tint, 
becoming rufous-pitchy only on the extreme margins ; the 
stria3 arc impunctatc, the scutellar striole well developed ; 
the interstices nearly ])lane, smooth, the 3rd Avitli a punc-
