T. coquus is entirely black except a spot of orange on each elytron 

 near the base, 



T. fulvipenne is larger and the elytra are entirely clothed with ful- 

 vous hair. 



A specimen in the collection of Mr. H. W. Wenzel, has the elytra 

 suffused with black, except where the spots occur in coquus. presenting a 

 form precisely intermediate. 



It is now considered a variety of coquus.

Color as in annulatum, but the elytra are smooth and the lateral 

 spine of thorax is even more marked than in the other species of the 

 genus.

Thorax coarsely punctured with a small lateral spine. Scutellum 

 moderate, broadly triangular, acute at tip. Elytra not pubescent.
