In this species the green gloss that more or less pervades the 
whole surface does not anywhere overpower the testaceous under- 
lying tint, though it is variable in respect of its intensity and 
distribution, being usually most conspicuous about the lateral and 
sutural margins of the elytra. In size and shape it resembles 
T, politus, but differs (apart from colour), in the prothorax having 
a fairly defined dorsal channel, in the puncturation of the same 
being strongly rugulose and in the sculpture of the elytra, which 
in front is a little more inclined to run in rows and a little more 
inclined to rugulosity, but in the hinder two-thirds falls into a 
perfectly longitudinal arrangement with well-defined and strongly 
convex interstices ; from T. porosus the small size, and prothorax 
much less than twice as wide as long, will distinguish this insect.

The separation between the clypeus and the front is scarcely 
marked, the latter having an obscure transverse impression (in 
some examples very obscure) near its anterior margin. The pro- 
thorax is slightly more than a third again as wide as long, the 
base not very much wider than the front margin ; the lateral 
borders are rather wide and diverge rather strongly from the front 
angles (which are moderately sharp and prominent) to behind the 
middle where they round off strongly and converge to the base 
which is widely and roundly produced backward, the hind angles 
being minute and dentiform ; the curve of the base is slightly 
bisinuate ; the lateral margins are slightly undulous and feebly
