BRITISH ICHNEUMONS. 



[Portzon 



in woods and marshes, though the male is the commoner sex by about 

 four to one. This has an extensive perfect existence from the middle of 

 June to 26th September and is almost invariably found upon the umbel- 

 liferous flowers oi Heracleum, fennel and angelica; the female, on the other 

 hand, occurs only from the middle of July to 5th September and is usually 

 found by sweeping, though I twice took it on angelica flowers and once 

 on those of Smyrnium olusatrum. I possess it from Blackheath, Plum- 

 stead, Oxshottand Harting (Beaumont); St. Margarets in Kent (Sladen); 

 a full series of both sexes from both Shere (Capron) and Felden (Piffard); 

 Reigate and Greenings in Surrey (Saunders) ; New Forest (Miss Chawner) 

 and Lyndhurst (Adams) ; Devonport (Garde) ; Colgate in Sussex (New- 

 bery); Abinger Hammer in Surrey (Butler); Bungay (Tuck); Godstone 

 in Surrey, Heacham in Norfolk and Ousden in Suffolk (Elliott) ; and one 

 female from Golspie in Scotland (Col. Yerbury). The remainder of my 



ninety specimens are from Huntingfield in Kent, Vcntnor in Isle of 

 Wight, and the Christchurch sandhills; from Denny Wood, Wilverly, 

 Lyndhurst, Matley Bog, Rhinefields, Brockenhurst and Hursthill in the 

 New Forest; and in Suff'olk from Benacre Park, Bentley Woods, Alder- 

 ton, Henstead marsh, Claydon, Lackford, Tuddenham Fen, Barton Mills, 

 Brandon, Foxhall, Shotley and Aldeburgh. The late date to which the 

 males extend in autumn, coupled to the fact that I have swept it from a 

 hedge bottom as early as nth April, 1898, shows that hibernation in the 

 perfect state is not improbable. The species has not been bred in Britain 

 from any recognised host, though Musham raised a male at Lincoln on 

 25th June, 1 90 1, from mixed pupae.
