Ent. Ber. Amst.
A new bumblebee species of the subgenus Megabombus is described from the Chilean Lake District. The type series consists of 74 queens, 36 workers and a single male. Queens show a tendency to melanism as has also been observed for the European B. hortorum and B. ruderatus. B. villarricaensis is both morphologically and in colouration close to those species but a number of differences are enumerated. The very considerable geographic separation from the known Garden bumblebees would also support specific ranking.
