8o BRITISH ICHNEUMONS. [Phygndeuofi. 



short, with the petiolar area discreted. Scutellum black, smooth and 

 shining. Abdomen black and centrally castaneous ; the three basal segments 

 strongly developed, with the remainder contracted and inconspicuous ; 

 basal segment slender, narrow and elongate, hardly explanate apically, 

 smooth, with no tubercles ; second segment broader and shorter than the 

 third ; terebra as long as the basal segment. Legs somewhat stout, tes- 

 taceous ; calcaria very short and curved. Wings hemipterous, reaching 

 the apex of the post-petiole, apically rotundate ; nervures incomplete, 

 though the stigma sometimes present. Length, 3-4 mm. 



Dr. Capron first found this little insect in Britain, and records it (loc. cit.) 

 from Shere ; there is a long series in his collection. It has subsequently 

 been discovered by Bignell, at Bickleigh, early in August ; by Piffard, at 

 Felden in Herts. ; and by Routledge, at Tarn Lodge, near Carlisle. I 

 once took it at Hursthill, near Brockenhurst, on 3rd August. It is widely 

 distributed in northern Europe.

Head with the vertex not broad, cheeks short, scrobes wanting, clypeus 

 arcuately discreted ; peristomium broad, mandibles stout and elongate. 

 Antennae basally fulvous ; of $ inserted far below the centre of the eyes, 

 and the three basal flagellar joints gradually decreasing in length, with the 

 first shorter than the scape. Mesonotum rosy. Abdomen castaneous ; 

 basal segment slender and elongate, of $ linear and twice longer than the 

 hind coxae, with the dentately prominent spiracles in its apical third ; third 

 segment of $ longer than second. Legs somewhat stout, calcaria very 

 short and curved ; fulvous, $ with the hind tarsi infuscate at base and 

 apex. Wings with the radial nervure emitted from the centre of the 

 stigma ; of ? squamiform ; the nervellus of the $ opposite and hardly 

 intercepted. Length, 3-4 mm. 



Thomson shortly describes both sexes as above, and it may be well to 

 add that the ? further has : — The face somewhat coarsely punctate ; frons 

 and vertex smooth, the former with scattered coarse punctures, and the 

 palpi flavous. Antennae half length of the body, with the joints from the 

 fifth transverse. Prothorax, mesonotum and scutellum red and glabrous, 

 with the notauli wanting ; meta- as long as the meso-thorax, with distinct 

 costae and areola ; petiolar area vertical and basally entire ; apophyses 

 distinct, though small. Abdomen with long and sparse pubescence ; first 

 segment with its basal half black ; anus retracted ; terebra hardly two- 

 thirds the length of the basal segment, its spicula acuminate and valvulae 

 pilose. Wings hardly reaching beyond the base of the metathorax. 



The $ differs from that of F. Heinevuinni in the posteriorly narrowed 

 head, strongly convex abdomen, sparsely pilose mesonotum, and in having 

 the spiracles of the second segment further from the lateral margin. 

 Even though P. Bonelli should prove to be distinct— and very little 

 appears to be known of this south European species — it was probably 

 erroneously catalogued as British in 1870, and no records of it exist.
