 arundinacea (L.) (Dictynidae) on 12. vi. 1952, England, Surrey, Bookham Common 

 {A. E. Le Gros). Imagines appear in the field May-August and I have found some 

 females during the winter amongst the foliage of coniferous trees, evidently 

 hibernating. 



The male of platyphilus has not been described ; but I have seen some males in 

 Dr. Boucek's collection which he considers to belong to this species.
