FIG. 45. Distribution of long-winged (white) and short-winged (black) specimens 

 of the Carabid beetle Bembidion grapei Gyll. (fig. 44) in Fennoscandia. Cf. legend of 

 fig. 14 (p. 153). 



The occurrence of the short-winged form indicates survival on ice-free refuges 

 of the western and northern coast during the last glaciation.
