(Steph.-Ill. Erit. V, 324; ianglb. Kaf. H. II, 650. - scrobiculatus 

 Erichs. Jen. Spec. Staph. 805; Kraatz Ins. D. II, 670; Thorns. Skand. Col.

Our largest, especially broadest species, most like T. bilineatus , 

 but easily identified by the arcuate, deep transversal impression of pro- 

 notum. 



Black, finely haired, glistening; antennae either entirely black or 

 their first joint brownish-red; legs pitch-brown vvith yellow tarsi and 

 tips of tibiae, occasionally brownish-red. 



The head is narrower than pronotum, finely and very densely punc- 

 tated, and on each side anteriorly inside boss of antennal base with a 

 rather deep longitudinal impression, eyes prominent and proportionately 

 large, temples short, antennae as long as head and pronotum together, 

 slightly thickened distally, their seconi and third joints of same length, 

 the middle ones (£-7) fully as long as broad; pronotum much narrower than 

 elytra, short cordate, with rounded— off fore-corners, and rounded— off ob- 

 tuse hind-corners, densely and rather finely punctated, posteriorly with 

 a* very deep, arcuate, anteriorly open transversal groove, at middle in 

 front of this with two oval, short impressions and often in front of these 

 furthermore a flat fovea in the middle-line; elytra 12 times as long as 

 pronotum, rather fine and dense punctation, anteriorly along the suture 

 slightly impressed; abdomen very finely and densely punctated. L. 3.5-4
