Pretty sure it's not a black C. vicinus. The first top down image shows the width of the head, which is wider than the thorax. Vicinus head is usually longer than it is wide, unless there is an OR variety of a black C. vicinus that I'm not aware of.
If you get a macro closeup shot of the head, look at the base of the scapes. On C. vicinus it is flattened, like this image here.
Need better lit images! But this is most likely C. modoc or C. laevigatus. If the hairs are white, it is C. laevigatus. If the hairs are brown/golden, that would be C. modoc.
Laevigatus, Modoc, Vicinus, that that order. Notice head proportions:
