The biological and archaeological implications of the beetle Aglenus brunneus (Gyllenhal) in ancient faunas

The distribution and ecology, as far as they are known, of the Colydiid beetle Aglenus brunneus (Gyll.) are summarized and the significance of its records from archaeological sites considered. The supposition that A. brunneus originated in North America (Peyerimhoff, 1945) is questioned in the light of the ancient records. The species is used to illustrate some of the general principles and problems involved in the theoretical reconstruction of past environments from ancient faunas.
