wider tliiiii the hoiui. lono;er th:m wide, distinctly narrower behind; sides dis- 

 tinctly sinuate, densely and rather coarsely but very evenly punctured with a 

 narrow smooth median space; elytra wider than the thorax, longer than wide 

 conjointly, distinctly and closely punctured, the punctures much finer than on tlie 

 thorax, spai-sely finely pubescent; abdomen densely, very finely punctulate, feebly 

 stiining ; beneath more opaque, the surface alutaceous, very finely but not densely 

 j)unctulate. Length .16 inch ; 4 mm. 



Sexual characters as in ciiirrdscciis. 



The |iuiictiircs of tlie head and thorax :dthoii<;h coarse are clo.sely 

 })laced. tho.se of the elytra are finer, rather clo,sely placed, but the inter- 

 vals are quite shiniii";. The elytra are usually uniformly hlack. but 

 sometimes narrowly testaceous at tip, and rarely with a sli^^ht aeneous 

 lustre. The leirs and coxae are piceous. 



Occurs in Colorado, Nevada and California.
