A recent collecting trip to Humboldt County, California, 

 brought to light several very interesting facts and what is be- 

 lieved to be a new species of Out us, which may be denned as 

 follows : 



Omus cupreonitens, n. sp. 



Elongate, glabrous, deep black and shining; lustre varying from 

 cupreous to glossy black. 



Head moderate, as wide as the pronotum, or slightly narrower ; eyes 

 feebly prominent; interocular region adjoining the clypeal base promi- 

 nent and convex, polished, very sparsely punctulate and feebly rugu- 

 lose at its periphery, and defined laterally by distinct frontal impres- 

 sions ; remaining frontal region irregularly and moderately coarsely 

 rugulose, the upper part of each frontal impression exhibiting a dis- 

 tinct vertiginous spot when viewed vertically from above, the adjacent 

 rugulae being concentrically arranged ; supraorbital rugulae parallel ;
