164 FAMILY EVANIID^. 



the following, although it has become naturalized in every region. 

 The student should become familiar with it before using any of the 

 other keys. Probal)ly the majority of the Neotropical species really

9. Face finely and thickly punctured cllinensi!« Szepligeti. 



Evania diniidiata Spinola. 

 Szepligeti has properly credited this species to Spinola. The 

 reference of it in Schletterer and in Dalle Torre's " Catalogus 

 Hymenopterorum " to Fabricius, Syst. Piez., p. 179, 1804, is a pure 

 mistake. Fabricius does not mention the name, and Spinola de- 

 scribes it as a new species.
