230 Mr. W. F. Kirby on Dragonflies 



eight species as new, one of which will form the type of a 

 new genus. Two or three others are also apparently un- 

 described ; but the material before me is not sufficieut to 

 render it advisable to describe them at present. 



The full synonymy of the known species will be found in 

 my ' Synonymic Catalogue of Neuroptera Odonata.' 



The new species are as follows : — 



Rhyothemis ducalis. Ortbetruin flavidulum. 



Urothemis Rendalli. Acisoma variegatum. 



iridescens. Phyllomacromia flavicincta. 



Stcechia (gen. nov.) Distanti. Lestes obscurus.

Four specimens.

 Libellulajlavescens, Fabr. Ent. Syst. Suppl. p. 285 (1798). 



Two specimens. 



Fort Johnston, Nyasaland (P. Rendall). 



The most widely distributed of all dragonflies, found 

 almost everywhere in the warmer parts of the world outside 

 Europe. 



3. Tramea basilar is. 



Libellula basilar is, Beauv. Ins. Afr. Amer. p. 171, pi. ii. fig. 1 (1805).
