Hob. Georgia (Abbot). 



I have seen a male from the collection of Abbot, in the Zurich 

 Museum. Is it really from America? 



A species common everywhere in Europe and Northern Asia. 



Calopteryx virgo Fab. Fauna Greenland. 196, 152, is perhaps 

 erroneously stated. Fabricius says that he only saw it once ; but 

 according to Schioedte, Berlin. Eiit. Zeit. Ill, 142, it has not 

 hitherto been discovered there. 



HETAERINA HAGEN. 



Wings rather narrow, densely reticulated ; pterostigma absent 

 or very small, quadrangular; basal space reticulated; base of the 

 wings, in the male, sanguineous. 

 * Pterostigma absent.
