This beautiful species closely resembles T. ambiens, 

 LeConte, but is broader, more shining, and slightly differently 

 coloured, with no red border to the thorax, but a broader border 

 to the elytra. The thorax is broader in front of the middle, 

 and less evenly punctured, the punctures on the middle of the 

 disk being small and those at the sides very coarse; the sides 

 are more distinctly margined. The elytra are very similar, 

 but have the apex of each more broadly truncate, the trunca- 

 ture being rectilinear. The prosternal process is very deli- 

 cately and sparsely punctured. The visible part of the meso- 

 sternum is very obliquely narrowed posteriorly. 



Although this species is so close to T. ambiens that at first 

 I thought it might be merely an extreme variety, it is note- 

 worthy that the mesosternum in the specimen described is 

 separated from the metasternum. No doubt this is accidental ; 

 but, as there does not appear to be any fracture, it is evident 

 that the connexion between the meso- and metasterna cannot 

 be so intimate as in T. ambiens, in which they are completely 

 connate.

The head is slightly tinted with steel-blue, excavated at 

 the upper part, sulcate at the lower part of the face, leaving 

 two oval swellings. The thorax has the sides very gently 

 arcuate ; the disk is raised and longitudinally channelled in 

 the middle, tinted with brassy green, closely and very dis- 

 tinctly punctured, and obliquely vermiculate-rugulose. The 

 large lateral impression is tilled with bright red, dull, velvety 

 pubescence. The elytra are rather flat and horizontal, closely 

 punctured with cuneiform punctures, with a rather smoother 

 line indicating the usual costa ; the apex of each is rather 

 broadly rounded and denticulate. The prosternal chin-piece 

 is very slightly emarginate in the middle. The presternum 

 is closely and rather roughly punctured, the process margined, 

 narrowed at the apex. Lateral carina of the basal segment 

 of the abdomen rectilinear posteriorly.
