female Osmia (Melanosmia) sensu lato
one of the Chenosmia (former more narrow subgenus)

this may or may not be the female of the male you posted earlier

I examined this specimen this morning
after Robbin Thorp suggested to see if it had a carinate ridge at the top back of the head. It does, & so does one of the males I looked at (not the one shown in the 'thumb'). Thus, this would be Osmia aglaia Sandhouse, acc. to Robbin.

Thanks, John!
I do have some specimens. Do you think it may be worth sending them to Robbin Thorp in Davis? New York is perhaps a bit far.

Don't think so -
not with two submarginals, robust shape, big head, and (sign of female) ventral scopa.
