Tlu' luiifjue specimen of tliis species wiis received too late to iiiiuiit of 

 fiiriiriiiii' ; it is much more robust tliuii T. velox, which it otherwise resem- 

 bles in some respects; iu color, iiowever, it is entirely dift'ereiit. 



After exiiminiiiu' all of (jrouvelhs's recently described species of this 

 j^enu.s, without beina: able to identify it amonj; tliem, I am ((uite confident 

 of its bcinu' new to science. 



One s|)ecim(!n collected in Soutliern Arizona by Mr. IVIorrison. 



I have dedicated this species to the late i)r. .1. L. Le(!onte, as a slight 

 token of reuard for this most enunent coleopterlst.
