could it be Stenolophus incultus or anceps? At first I thought anceps, as the elytral iridescence seems visible in your photos, yet the first elytra stria is not pale, and ~2/3 of the base of the tibiae are pale (vs 1/2 of the base in anceps). The pronotal basal fovea are also fairly well defined and strongly punctured in this one. Both species occur west of the Rockies, including on Vancouver Isl. Based on pronotal shape alone (disregarding the color of tibiae and elytra), I feel like the thickness of the lateral margin and hind angle shape matches Lindroth's figure for anceps slightly better than incultus, but they are so similar...
