Looking at the map, I have often wondered what bees might be found in those great northern regions of Alberta and Saskatchewan, from which few collections have been seen. Professor E. H. Strickland has sent me numerous species of Andrena from the region about Edmonton and thence southwest to Lethbridge. But he has also included two species obtained in the far north, in a latitude about the same as that of the southern tip of Greenland. They are quite different from the more southern species, and so far as I can see, they have not been described. It would thus appear that there is a distinctive northern Andrena fauna, probably of few species.
