If it is
Mesembrina (I have no reason to asume otherwise), I think it is
M. mystacea. Of the two species with bumblebee-like appearance, that is the one with dark hairs on the posterior part of the mesonotum and on the scutellum.

This looks exactly like my specimen of
M. mystacea found once in Ireland as an accidental import with French cattle (Agricultural College, Co. Antrim). I also saw it in Lausanne
and Montreaux last year, near Chateau Chillon
