Mr. Kirby gives his reasons, at some length, for considering this 
species identical with thj^t of 0. Fabr., who mistook his for the Apia 
alpina of Linne (See 1. c. p. ccxvii), and which species Mr. Smith 
(Bees of G-reat Britain, p. 222) quotes as a synomym of B. nivalin 
Dahlb., a species with the apical segments of the abdomen yellow, and 
consequently quite different from B. Arcticus.
