284 BRITISH ICHNEUMONS. [Bajichus. 



area, sometimes also a line beneath the hind radix and on i)ronotum, 

 flavous. Scutellum and more or less of the postscutellum flavous ; 

 former with an erect, acute and sometimes black, spine. Abdomen black 

 with all the segments broadly flavous-banded and the last generally 

 entirely flavous. Legs pale ; the finely and closely punctate coxae, base 

 of the trochanters, and more or less of the femora, black ; apices of tibiae 

 and tarsi ferrugineous. Wings fulvescent ; stigma fulvous and tegulae 

 flavous. Length, ii — 13 mm. 



Extremely closely allied to the last species, with which it has been 

 much mixed in our collections ; thereform Thomson says it may be dis- 

 tinguished by the mesopleurae being finely and closely punctate and not 

 coriaceous, by the larger scutellar spine, and more profuse decoration of 

 the head and thorax ; he also instances the finer coxal puncturation, 

 which in certain specimens is very marked, but does not appear to me to 

 be a constant character, as certainly is both the larger scutellar horn, the 

 longer and more curved external nervure of the areolet and, perhaps, the 

 much paler apices of the hind tibiae. 



This is a very common species with us and we have a long list of 

 localities, some of which should doubtless be ascribed to B. volutatorius. 

 It was first noticed in Britain by Donovan, who figures it well early in the 

 last century ; Hope sent it to Gravenhorst from Netley in Shropshire, and 

 the latter says it occurs on umbelliferous flowers in August. Brischke, 

 who bred it from PanoUs pinipcrda in Prussia, tells us that the cocoon is 

 similar to that of ^. volutatorius. There is a specimen bred from Pygaera 

 bucephala in the York Museum ; and Bignell has raised it in the middle of 

 March from, probably forced, Sdcni'a illiinaria in South Devon (Buckler 

 and Entom. 188 1, p. 141), Dr. Wratislaw found it about Bury St. 

 Edmunds (z« col. Chitty) ; and Curtis says (B.E. 588) that it occurred to 

 him on flowers in woods in Suffolk in May. Bradley took it at Colwich, 

 near Birmingham (E. M. M. i8g6, p. 165) and Dale at Middlemarsh and 

 Parley Heath in Dorset. It has been bred by Gir from Smerinthiis populi 

 and Perris from Trigonophora empyrea (Ann. Soc. Fr. 1877, p. 406). 

 Morice has captured it at Ripley and Long Cross in June ; and Johnson 

 at Churchill in Co. Armagh (Irish Nat. 1904, p. 256). I have seen 

 examples from Whauphill in Wigtonshire sent by Gordon ; Folkestone by 

 Stanley Edwards ; Colwich and Wyre in May and June by Martineau ; 

 Guestling near Hastings by Rev. E. N. Bloomfield ; and Brockenhurst in 

 June by Cross. It has occasionally occurred to me in the Bentley Woods 

 near Ipswich, between 26th April and 31st May, flying in the afternoon 

 about three inches above the grass and buttercup-leaves (looking very like 

 Crahro cribrarius) and occasionally settling on some fallen tree trunk 

 or log.
