Porritt has bred this species from reeds in Britain and, on the Conti- 

 nent, it is known to prey upon Nonagria <^eminipuncta, JV. paludicola, 

 Leiicatiia obsolehi and Senfa mariiima. Stephens says it is scarce, and 

 records it from near London, in June ; Bridgman took it at Brundall near 

 Norwich, in July and September ; Elliott swept a fine female in Tudden- 

 ham Fen, in June, 1901. I have only met with it in the most boggy 

 situations, always upon reeds ; Oulton }3road and Brandon, Suffolk, from 

 the middle of May to the beginning of July. Chitty took it in the Isle of 

 Sheppy, early in September, 1901.
