Geographical distribution: -— Northern and middle Europe down into Bohemia; towards the north to middle Sweden. Wood remarks that the species seems to be double brooded, as, besides in early summer, it again occurs in August to October. 2. A. picta Lehm. 1822. Lehm. Indie, schol. Hambiirg, 43, Tab.
