Subfamily DUFOUREINAE 



Although this subfamily is chiefly Holarctic in distribution, it is also represented in the 

 Ethiopian, Oriental and Neotropical regions by at least one or more species. It is absent in the 

 Australian Region. Many, if not most of the species, are apparently highly restricted in their in- 

 trafloral relationships and thus oligolecty is a relatively common phenomenon of this subfamily.
