REMARK. There are two specimens of Megachile circumcincta listed without their sex in Shumakova et al. (1982). Only one of them (a female) collected near Golubtsovo (Altai

Terr.) was found in the ISEA collection and belongs to M. ligniseca (Kirby, 1802) . It is possible that all of the data for this species in Shumakova et al. (1982) are based on a misidentification. The data in Sarychev and Sarycheva (1989) are not confirmed from preserved specimens, so these data are doubtful too. However, M. circumcincta is a trans-holarctic species, so there is no reason to exclude it from the fauna of Novosibirsk Prov. and Altai

Terr., although verification of its presence is needed.
