the following segments, rugosely sub-strigose ; terebra hardly exserted. 

 Legs normal, red ; coxae excepting sometimes the anterior of the 6, base 

 and apex of the hind tibiae and in c? sometimes a[)ices of the femora, with 

 the posterior tarsi, black. AV'ings slightly clouded ; tegulae black, radix 

 stramineous. Length, 7-9 mm. 



/. transfuga is rather larger, and Gravenhorst also mentions a $ 

 with the anterior femora nearly entirely black. Concerning the ty{)ical 

 ? , he says of the sixth to the ninth antennal joints " supra a//>idis,'" but 

 Taschenberg does not refer to white coloration and, on the contrary, 

 divides it from P. iinprobus, var., by its bicoloured flagellum. 



Rev. F. W. Hope took /. transfuga at Netley, in Shropshire ; and 

 the type form is said to occur throughout Europe, in June. There are, 

 however, absolutely no S[)ecified British records of it, and I possess but a 

 single female, in which I place but little faith, named by Dr. Capron, and 

 taken by Mr. Albert Piffard at Felden, in Herts. Stephens, with his usual 

 abandon, says it is rare in England, quotes Hope's record and adds the 

 London district. 



17. flavimanus, Grav. 



Phygadeiton flavimanus, Gr. I. E. ii. 647 ; Ste. III. M. vii. 296 ; Tasch. Zeils. Ges. 

 Nat. 1865, p. 23, i ; Thorns. O. E. x. 956, 6 ? . 



Head black ; of $ with the internal orbits white, palpi flavous and 

 mandibles centrally castaneous ; frons strongly punctate, eyes glabrous, 

 vertex not narrow ; clypeus sub-discreted, obtusely tridentate apically. 

 Antennae of $ slender, setaceous, as long as the body ; of ? with the 

 scape and two basal flagellar joints, of which the first is the longer, infus- 

 cate, and the four following stramineous, the remainder suddenly deep 

 black. Thorax immaculate ; metathorax coriaceous, with the costae 

 elevated and the basal areae entire ; petiolar area oblique, deplanate, and 

 distinctly discreted ; apophyses wanting, spiracles large and circular. 

 Scutellum black. Abdomen de|)Ianate, not broader than the thorax, 

 ovate, black ; anus of ? narrowly white ; basal segment elongate, carinate, 

 with post-petiole parallel-sided and a little longer than broad ; the follow- 

 ing segments closely and obsoletely punctate ; terebra shorter than the 

 petiole. Legs normal, red ; anterior femora sometimes centrally infuscate, 

 coxae and trochanters mainly black \ hind coxae, base of their trochanters 

 and centre of femora, black ; hind tibiae basally or entirely, and their 

 calcaria, ferrugineous. Wings somewhat clouded ; radix stramineous, 

 tegulae black \ radial cell elongate. Length, 5-7 mm. 



This species differs from the last-described in its apically elongate radial 

 nervure, obsoletely punctate abdomen, and paler legs. P. vulnerator, 

 which was indicated as its probable female by Taschenberg, is now con- 

 sidered quite distinct and related to P. afflic/or, though its S is still 

 unknown. 



Not uncommon; found in the south of England in the beginning of 

 September (Stephens) ; one male, at Mousehold, near Norwich, in July 

 (Bridgman) ; bred from Emphylus serotinus (Entom. 1S82, p. 276).' It is 



1 Miss Chawncr has called my attention to the frequency witli which Emf>hylus tibialis falls a 

 victim to the attacks of Iclinciimuniilac ; she says 0" '''• Jnnc i7lh, 1906) that very often the larvae 

 appear to die off prematurely before the parasite is fully trown, and so both host and parasite perish 

 toKether; she has often seen quite young larvae die off after having been "stung," though no Ichneu- 

 inunid effected its ciuergcuce.
