FUBTHEB NOTES ON THE ODONATA OF CONSTAN- 

 TINOPLE AND ADJACENT PAETS OF ASIA MINOE. 



By Kenneth J. Morton, F.E.S. 



Since the appearance of my " Notes on the Odonata of 

 Constantinople" ('Entomologist,' 1915, pp. 129-134), Major 

 Graves has kindly sent me two additional lots of dragon-flies 

 collected by him in and around Constantinople, and at Kury 

 Yalova and Brusa, in Asia Minor. These include some species 

 which are not mentioned in my former list, and as the existing 

 information regarding the dragon-flies of the region is none too 

 full, it may be well to publish these further records. Another 

 reason for doing so is to call attention to the examples of Lestes 

 viridis, which in some respects differ from the ordinary form of 

 this species as it is known to me from Central and South-Western 

 Europe and Algeria. The following species were not included in 

 the collections previously received from Major Graves : Lestes 

 vlrens, Cercion lindeni, Pyrrhosoma nymphula, Aeschna mixta, 

 Somatocliloraflavomacidata, Sympetrumfonscolombei, S. meridionale 

 and Orthetrum anceps.

Somewhat smaller and less robust than specimens in my 

 collection from Switzerland, South of France, Sicily and Algeria, 

 and there seems to be a constant and quite noticeable difference 

 in tbe fprm of the superior appendages in their dorsal aspect. 

 To follow the diagnosis of de Selys ('Bevue des Odonates,' p. 148), 

 these appendages in Lestes viridis show interiorly a basal tooth 

 and what he terms a "tubercle" before the extremity (the 

 expansion seems, however, to be too gradual for this term to be 

 strictly appropriate). In his more extended description he says 

 the inner margin is, as it were, divided into three lobes, of which 

 the first is terminated near the base by an obtuse tooth, and the 

 second by a tubercle before the extremity. In the eastern 

 examples now under consideration this tripartite division is little 

 evident, the distal tubercle being apparently represented by a 

 weak tooth which scarcely projects beyond the inner margin of 

 the appendage. There is a certain amount of individual variation 

 in the appendages of both forms, probably in part due to unequal
