Fhygadeuon.] BRITISH ICHNEUMONS. 95 



post-petiole distinctly dilated apically, deplanate, glabrous, suh-carinate 

 and a little longer than broad ; terebra sligluly longer than the basal 

 segment, with black valvulae. Legs red, with the coxae and trochanters 

 alone black. Wings sub-hyaline ; radix white, tegulac black, nervellus 

 antefurcal ; radial nervure not thrice longer apically than basal ly. 

 Length, 4-6 mm. 



This species is very like P. futnator in its punctate pronotum and 

 metapleurae, but the abdomen has the post-petiole sub-quadrate and 

 broader, the ? anus compressed and the terebra longer, with the hind 

 femora more strongly punctate ; the $ antennae, tegulae and mandibles 

 are black, with the areola longer and emitting central costulae. 



P. hercynicus was first mentioned from Britain, with no note of its being 

 an addition to our fauna, by Bridgman (Trans. Norf. Soc. v. 613) ; and 

 most of the records under P. tiitidus probably refer to it, since it is a 

 common species on Angelica sy/vestHs flowers in marshy places, at least 

 throughout the southern half of Britain, from the end of August to the 

 first week of October, (niestling, in Sussex (Bloomfield) ; Rediand, near 

 Bristol (Charbonnier) ; Copthorne Common, Surrey (\V. Saunders) ; 

 Plumstead in July (Beaumont) ; Lyndhurst (Adams) ; Wicken Fen and 

 Tostock (Tuck) ; Eaton, Heigham and Brundall (Bridgman) ; Devon 

 (Bignell). I have invariably found it upon carrot and Angelica flowers, at 

 Crookham in Berks., Felden in Herts., Horsham St. Faith in Norfolk ; 

 and in Suffolk at Claydon bridge, Henstead marsh, Beccles, Barnby 

 Broad, Foxhall and Eye. I cannot find that it has yet been bred. 



26. brevitarsis, Thorns. 



PhygaJeKon brevitarsis. Thorns. O. E. x. 959, i ? . 



Black ; abdomen centrally broadly, with the femora and tibiae, red ; 

 terebra slightly shorter than the basal segment. Length, 4-5 mm. 



This species is shortly diagnosed as above by Thomson, who adds that 

 it is very like the last-described, but that its head is less cubical, the 

 flagellum pilose and obscurely red towards the base, with the joints shorter, 

 and that the terebra is obviously shorter than the basal segment. 



Professor Thomson identified an example of this species sent to him by 

 Bridgman, who had considered it to be simply a variety of P. ni/idns, and 

 who took it at Earlham and Wroxham, in Norfolk, in August and Sep- 

 tember. The only specimen I have seen is one, named by Professor 

 Brauns, which I beat from Finns sylveslris in the Bentley ^Voods, near 

 Ipswich, on 2nd April, 1899, probably after hibernation.
