depression; eyes large, flat, converging in front; rostrum 

 a little longer than broad and rather strongly curved, on 

 the upper side distinctly narrowed towards the apex; the 

 bristles on the elytra short and strongly sloping; inter- 

 stices flat. 



From T. bifoveolatus it is distinguished by the totally 

 different shape of the elytra and of their bristles behind. 

 The elytra of T. bifoveolatus are about one third longer 

 than broad, broadening slowly from the shoulders until 

 behind the middle, where the breadth is culminating, not 

 reaching one time and a half the breadth of the thorax. 

 The elytra of T. angusüsetuliis are shorter and broader, 

 not more than one fourth longer than broad, rapidly 

 broadening from the shoulders, thence with parallel sides, 

 and behind a little more abruptly narrowed than by T. 

 bifoveolatus. The maximum breadth of the elytra as 

 compared with that of the thorax is not less than 3 to 2. 



T. bifoveolatus has the bristles*) on the hind part of 

 the elytra strongly broadened towards the tip, where their 

 breadth is culminating and where they are much broader 

 than at base and more or less sharply truncate; the length 

 of the bristles as compared with their width at the tip is 

 about 5 to 2. In T. angustisetulus the bristles are only 

 slightly broadened from base until near the middle, where 

 they are broadest, though only a little broader than at 

 base, and thence more or less tapering; the are not less 

 than 4 times as long as broad. 



Besides the scales of the elytra are more irregular 

 and angular and in spots with plain metallic reflection 

 (which may also be observed in clean specimens of T. 

 bifoveolatus, though in a less pronounced degree); 'the 

 striae of the elytra and their punctuation is finer. 



From T. coloratus Allard (1. c. pag. 179) it may be 



*) Some of the bristles especially towards the sides may be some- 

 what narrower.
