DRAGON-FLY HUNTING IN EASTERN SWITZERLAND. 



BY KENNETH J. MORTON, F.E.S. 



{Concluded from page 4). 



The weather luid now become settled and very hot, and the Sth 

 saw us back for the day to near Zurich, our destination being the 

 Oerlikon Riet, including the River Glatt, and our special quarry the 

 Qomphince and Somatochlora Havomaculata. Taking the train to 

 Glatt brugg, our course led us along the banks of the Glatt fur a 

 stretch, then over the Riet to Oerlikon Station. The Glatt is here a 

 slow stream with corrected course. On either side of it stretch 

 tracts of marshy meadow with little clumps of wood, an ideal locality 

 for Neuroptera. Perhaps in no other place did we see so many 

 dragon-flies. It is no exaggeration to say that Calopteryx spleiidens 

 must have existed in thousands on the short reach of the river which 

 we traversed. I have hardly ever witnessed a prettier sight than 

 these multitudes of lovely dragon-flies. A female never took flight 

 without having half-a-dozen or so male attendants in her tram, and 

 these curious little processions were constantly flittiiig about the 

 river. Not less numerous, but less conspicuous, was Platycnemis 

 pennipes. Anax imperator was present in fair numbers, each patrolling 

 his special section steadily, except when a wandering Oomphus 

 provoked the tyrant to a chase. A worn $ of A. parthenope was 

 taken ; it had probably flown from the Metmenhasler See. The 

 Gomphids were not common and were diflicult to catch, the difficulty 

 being enhanced in no small degree by the relentless attacks of Tabani
