era route is more convincing. The collecting efforts invested in the Korean peninsula is still insufficient, especially in Central and Southern Korea. Further activity will surely prove the occurrence of additional species. From the bibliographical survey of the distributional ranges of Eurasian species, the following species can be enumerated as such candidates: Northern forms B. (Pr.) jonellus Kirby B. (Pr.) cingulatus Wahlberg B. (CI.) unicus Morawitz B. (Th.) deute

ronymus Schulz B. (Th.) muscorum (Linné) B. (Ls.) laesus Morawitz B. (B.) lucorum (Linné) Southern forms B. (Th.) filchnerae Vogt (= adventor Skorikov) B. (Th.) anachoreta (Skorikov) B. (Pr.) ardens Smith B. (Tr.) atripes Smith B. (Th.) unicolor Friese (= hedini Bischoff) But these basical geographical trends on the Korean bumblebees may not be much altered by further studies.
