NEW AUSTRALIAN SPECIES OF THE FAMILY 

 CALOPTERYGID^. 



By K J. TiLLYARD, M.A., F.E.S. 



Only one species of this exceedingly beautiful and interesting 

 family has so far been described from Australia, ^^iz., Diphlehi a 

 lestdides Selys. Two additions are now made, one being a com- 

 mon East Indian species, and the other a beautiful Diphlebia from 

 Northern Queensland. 



It is probable that systematic collecting in the Cape York and 

 Port Darwin districts would add several more species of this 

 family to our Australian Odonata^ since the Calo'pterygidcf are 

 exceedingly well represented in the tropical zone.
