Apis virginalis Geoffroy inFourcroy, 1785, p. 450).Nomenclatural remarksA female in the collection of the LinnaeanSociety of London, labelled terrestris, has beenrevised to B. lucorum and the two subsequentspecimens in the same row, both of which arequeens with no labels, were revised to B. lucorumand B. terrestrr^r respectively. In referring to thedocumentary value of the Linnaean collectionp, 10, and to secure stability in nomenclature,B. terrestris, in sensu passed and present authors(Sladen l9l2; Schmiedeknecht 1930; Pittioni1939a; Kriiger 1950, 1954, 1956, 1958; Yarrow1959; etc.), is kept. The species is not rare inUppland county, the home area of Linnaeuswhich also is the type area.First Scandinavian recordsNorway. Hereby published for the first time.Sweden Uppland (Linnaeus 1758).Taxonomical remarksNorwegian records hitherto published as,B. terrestrisapply to B. lucorum (Loken 1960), cf. referencesto the synonymy of this taxon. Accordingto present revision, they may also include B. magnus.The mention of B. terrestris in Swedenconcerns ,8. terrestris, B" lucorum, possibly alsoB. magnus when referring to Southern Sweden,cf. authors (partim) in references to the synonymyabove, but only ,8. lucorum, possibly B. magnus,when referring to Northern Sweden, cf. referencesto fire synonymy of B. lucorum. Swedish B. terrestrisand B. lucorum were quite recently distinguished,cf. references above.Queen, workerMorphological characters. Malar space markedlyshorter than distal width. Labrum (Fig.l2A).
