This is Cclithemis ornafa a of Ris, Coll. Zool. Selys, Libel- 

 lulinen, page 1193. Working independently of this later note 

 by Dr. Ris, I arrived at the conclusion that northern speci- 

 mens, heretofore referred to ornata, were a distinct species, 

 and in the preceding key I have indicated characters for its 

 recognition in addition to the equally valuable characters well 

 described by Dr. Ris. Dr. Ris's description of ornata, on 

 pages yzT^, 724 and 72y of the work above cited, was largely 

 based on specimens of martha which explains his statement 

 under B, p. 723, 'Tm Discoidalfeld der Vorderfliigle 3 Zellen 

 an t, dann 2 Reihen," which is true of martha, but not of 

 ornata.
