Male. Size and appearance much like T. nietanus Sauss., from which 

 it differs only as follows: The facial costa is slightly broader and less 

 excavated below the ocellus; the occiput and pronotum less rugose; the 

 antennae nearer cylindrical. The color is darker, the sides being deep 

 black throughout to the tops of the elytra; the posterior part of the 

 occiput and dorsum of the pronotum an ashy gray} the front lobe and 

 lateral margins of the pronotum dotted with black; the upper edge of 

 the posterior femur has two yellow spots, one next the base the larger. 

 Beneath shining black. Wings as in nietanus; base rosaceous, posterior 

 border broadly margined with black, and a fascia of the same running 

 along the anterior margin nearly to the base. 



Dimensions: Male, length, 1 in.; to tip of elytra, 1.25 in.; femur, 

 .67 in.; tibia, .53 in. 



Habitat: Found near Canon City, Colo., in a mountain canyon. 



I have not seen the female. It may possibly be a variety of T. 

 nietanus, but its variations from that species, added to the fact that it 

 was found at but one point, justify me in describing it as new. 



This species is decidedly the most variable of the Kansas forms. A 

 great many of the specimens have very striking white pronotums. The 

 species is found strictly in the western part of the state.
