﻿ODONATA FROM THE ENVIRONS OP CONSTANTINOPLE. 



131 



The male from Beikos is rather remarkable. It has the 

 narrow wings of simillinius-schneiderii, and traces of the yellow 

 dorsal line on segments eight and nine ; the median lines on the 

 anterior part of the thorax are produced laterally as in simillimus. 

 I hesitate to separate this example from those from Amasia, but 

 it raises a doubt as to whether sckneiderii is really to be closely 

 associated with vulgatissimus, as proposed by De Selys and as 

 Bartenef has done in his various writings.

Profile View of Appendages. 

 1. Gomphus Schneider a, Constantinople. 2. G. schneiclerii, Amasia, Asia Minor. 

 3. G. vulgatissimus, near Zurich. 4. G. simillimus, Le Blanc, France. 



The real connection seems rather to be with G. simillimus, 

 and if I had been dealing with this Beikos example alone, I 

 should have decided that it was a melanic Eastern race of 

 G. simillimus, a view which receives support from Bartenef's 

 record of G. vulfiatissimus vulgatissimus and G. vulgatissimus 

 schneiclerii from the same locality in Montenegro (' Notice sur 

 les Odonates du Montenegro,' Eevue Russ. d'Entom. xii. 1912, 

 No. i. p. 79). The appendages of the Beikos example agree 

 with Bartenef's figure of G. vulgatissimus sckneiderii (Arb. Lab. 

 Zool. Kab. Univ. Warsaw, 1912," Odonata of Signakh and Telav
