Mark record


The important species of predacious ants in Europe and North America belonging to the Formica rufa L. group, and their association with forest insects, is discussed. The absence of desirable species in Quebec is stated, and a brief description of an aggressive western North American species (F. obscuripes Forel) is given. The method used in collecting large colonies of this species in Manitoba, of transportation to Quebec, and of the eventual release and establishment is described. It is concluded that F. obscuripes is increasing in number in Quebec, and should be considered as permanently established.
