Pimph.] BRITISH ICHNEUMONS. 101 



rowly subcastaneous or testaceous ; the seventh of the $ transverse and 

 apically truncate, with its hvpopvgiuni exserted and apically constricted ; 

 terebra hardly half length of abdomen with the valvulae shortly pilose. 

 Legs somewhat stout, red ; the anterior with the coxae basally and tarsal 

 claws nigrescent, and a paler band before the base of the tibiae ; hind 

 tibiae and tarsi infuscate with a white band before the base of the former; 

 apical joint of hind tarsi about double length of the penultimate, claws of 

 9 not basally lobed. Wings more or less clouded ; radix usually white, 

 tegulae infuscate or concolorous ; stigma piceous with base pale ; areolet 

 irregular or subsessile ; nerwllus intercepting far above the centre. 

 Length, 4I — 10 mm. 



From my description of P. ixaiiihia/ar, this s{)ccies differs onl}' and 

 solely in the coxal colouration ; Thomson says it may be known therefrom 

 by the fenestrae of the second recurrent nervure being divided by a dot 

 in place of a line, that the 9 has the sixth and seventh flagellar joints 

 more abruptly shorter, the J face less convex with its puncturation finer 

 and sparser — all of which points I utterly fail to follow ; he adds that the 

 V has no pre radical pale line (there is, however, usually a pale callosity) 

 and the ^ the basal segment more strongly elevated apically (which, 

 though presumably a good structural feature, is, in reality, inconstant). 



I possess J (5 oi F. exa??utia/o?- with the tibial band as rufescent as that 

 oi P. slrigiplcuris ( = /*. tiirwncUae,\2iX. 2, Grav.); moreover the metapleurae 

 of the present species are often strigose posteriorly in specimens with a 

 pure white tibial band. Nor do I find that P. fiavicoxis { = P. ttirionellai\ 

 var. 3, Grav.) differs in anything but the paler coxae, in 9 the basally 

 paler flagellum, in J the flavidous scutellum, under side of the scape and 

 rarely a concolorous pronotal callosity. The variation of the coxal colour- 

 ation, so far from justifying the erection of distinct species, appears to me 

 to lend probability to the synonymy of the older authors, Geoffroy, Olivier, 

 etc., of P. itin'onc/lae with P. examinator. Gravenhorst describes a variety 

 oi P. turioiiellae {yzx. i) with the anterior coxae and base of their tro- 

 chanters black, and of P. cxaminatoi- (var. 2) with the anterior legs nearly 

 entirely flavescent {^cf. also Brischke, Schr. Nat. Ges. Danz. 1880, p. iii 

 et Tosquinet, Ann. Soc. Belg. 1897, p. 285). Mr. Bankes has kindly given 

 me seven $ $ the colour of whose coxae ranges from entirely black in one 

 individual to entirely castaneous in another; they were bred together with 

 a couple of Limncrae ^ J , and a 9 Eiibadizon extensor, Linn., in the Isle 

 of Purbeck, Dorset, June 28th to July 17th, 1902, from Sericoris bifaseiana, 

 Hw. Although the synon)'my of these two species cannot yet be estab- 

 lished, 1 have pointed out below how frequently they are associated on 

 the wing ; and it is also significant that 1 have never captured a 9 

 with black coxae," though, as noticed under the last species, males so 

 coloured are extremely frecjuent. P. spuria, (ira\-., considered as synony- 

 mous with this species by Marshall, is now treated as distinct by modern 

 Continental authors. Between it and the present species there is a some- 

 w^hat connecting form, which 1 will here describe as var. rufitibia {twv.) 

 of P. /urionelloe, from which it differs in having the hind tibiae and tarsi 

 — excepting the white band — clear red in place of nigrescent, with at 

 most the extreme base of the former infuscate ; it is not a connnon form 

 and I have seen but four 9 9 : — One found by Mr. Esam about Hastings, 



• Since the above was written I have been deUKhtcd to find, in an odd box, a female with black 

 coxae, taken by me on the flowers ol Aster Iripolium in the salt marshes at Southwold, on 28th Sep- 

 tember, 1900 ; this at least i)roves that both forms occur in Britain.
