96 BRITISH ICHNEUMONS. [Phygadeuon. 



sub-buccate and somewhat short ; mandibles stout and piceous, palpi 

 infuscate. Antennae short and black ; of S attenuate towards the apices, 

 of 9 sliorter than half the body, with the flagellum red and hardly attenuate 

 basally, its first joint slightly longer than the second and a little longer 

 than the scape, the fourth not transverse. Thorax sub-cylindrical, immacu- 

 late, nilidulous and pubescent ; pronotum basally striolate, with elongate 

 epomiae ; mesonotuni, especially in the $ , sparsely but not finely punctate, 

 with short and deeply impressed notauli ; niesosternum sparsely but dis- 

 tinctly punctate laterally, sternauli deep and hardly abbreviated posteriorly ; 

 metathorax not rugose, with complete areae, of which the basal is transverse 

 and narrowed behind, and the petiolar does not reach beyond the centre ; 

 costuiae entire. Scutellum black ; of $ deplanate, sub-glabrous, with 

 the basal fovea transversely linear ; of S punctate and more convex. 

 Abdomen lanceolate, red and sub-compressed apically, with segments six 

 to eight of the $ black ; basal segment as long as the slender terebra, 

 sub-arcuate, deplanate, black, its dorsal carinae short and spiracles sub- 

 prominent ; post-petiole quadrate, of $ punctate-alutaceous, of S rugosely 

 striate ; second segment of ? smooth and sub-quadrate, of 6 isolatedly 

 punctate. Legs somewhat stout, black ; anterior femora except in cj 

 basally, tibiae and tarsi, with the mutic hind tibiae except in S at base 

 and apex, red. Wings sub-hyaline, radix white, tegulae black ; stigma 

 sub-triangular and nigrescent, pale at the base and apex, emitting the radial 

 nervure behind its centre, the latter twice shorter basally than tlie slightly 

 curved apical abscissa ; areolet regular ; nervellus oblique and a little ante- 

 furcal. Length, 7-8 mm. 



This species closely resembles P. hercynicus, but it is nearly twice larger, 

 with the post-petiole less smooth, bicarinate, centrally canaliculate, and 

 somewhat dull, the hind femora are sometimes black (though "not so 

 described by Gravenhorst) and the abdomen is broader and less com- 

 pressed. 



Kriechbaumer (Ent. Nachr. 1892, p, 364) says P. diaphanus occurs in 

 August and September, has the metathoracic areola obsolete and is most 

 closely allied to P. cephalotes and flavimaniis. 



It is not an uncommon species in north and central Europe, where 

 it occurs in August on umbelliferous flowers. Taken about Netley in 

 Shropshire (Hope) ; the female in Darenth Wood in June and in Salop 

 (Stephens) ; Earlham, Eaton and Heigham, in September (Bridgman) ; 

 Bickleigh, in the middle of September (Bignell). I am of opinion that 

 most of the British records refer to P. hercynicus, though one or two of the 

 females found by Capron about Shere and three males, which I took on 

 Angelica flowers at Claydon bridge, near Ipswich, in September, 1898, 

 appear to be correctly here placed.
