270 BRITISH ICHNEUMONS. yophion 



(Hiiggari), and Iroiii Jrvinc Moor in July, 1900 (Dalgiisli). Cluttcn sent 

 nic eight cocoons from Agrolis praecox in October, 190S, from which six 

 parasites emerged between loth and 15th of the following June; I bred 

 it at Ipswich on 6th June, 1H94, and have met with it there in August at 

 electric light, at Alderton on Foeniciihim vulgarc and at Peterborough on 

 Nerackum splumdyliinii ; but this genus is very rarely seen on flowers and 

 more usually found, as is the present species at Monks Sohani, at light 

 and on yew-tree leaves in the mid-September sunshine, occasionally flying 

 about hazel in lane hedges, as 1 noticed it near South wold early in Sept- 

 ember, 191 1. Excepting those bred, 1 have no record of its occurrence 

 before the middle of August. 



5. parvulus, Kriech. 



Ophion parvulus, Kriech. Ent. Nachr. 1879, p. 104, <? ? (ncc Vol!. Pinac. 

 pi. xxxix, fig. 2, cf ). 



A small rufescent-testaceous species, with diffuse pubescence. Head 

 not posteriorly broad; eyes contiguous with ocelli and mandibular base; 

 orbits indefinitely flavous. Antennae as long as or a little longer than 

 body. Thorax unicolorous; metathorax with but slight trace of carinae — 

 areola, and the basal transcarina usually entirely, wanting; J mesonotum 

 and metathorax sometimes infuscate. Scutellum not laterally carinate. 

 Wings hyaline; stigma pale flavous and not small; nervelet elongate or 

 wanting; nervellus po.stfurcal, intercepted hardly below its centre. 

 Length, 12 mm. (Kriech.) or 9-10^ fBritish). 



Distinct in its small size and wanting basal metanotal transcarina from 

 all other Ophiones, except O. ?)iinu/iis, from which 1 find nothing but 

 colour to distinguish it. In the British examples the stigma is unicolor- 

 ous red, and the nervelet distinctly short. 



Extremely rare with us, and not hitherto noticed as British. I first 

 took a male on oak in the New Forest at Brockenhurst on i6th May, 

 1895; but it probably occurs in all our more southern wooded districts, 

 since another turned up on eight-foot birch bushes in Assington Thicks 

 on 17th IMay, 1901, and a female was taken flving about birch bushes on 

 the afternoon of 29th IMay, 1902, in the Bentley Woods, also in Suff"olk. 

 Kriechbaumer described a single pair bred in Bavaria from pupae of 

 Plastenis retusa. I do not know where Mocsary records it from Cucullia 

 ieiiaceti, Schafi". and C. artnnisiac, Hufi'n., as given by Dalla Torre (Cat. 

 197). My examples are very different from Vollenhoven's male figure, 

 with its remote ocelli and stramineous stigma; the species is not men- 

 tioned at I.e. p. 61, as indicated by several authors. 



6. forticornis, sp.n. 



A rufesccnt testaceous sj^ecies, with close i^ibescence. Head with 

 vertex somewhat narrow, but temples as broad as eyes which are nearly 

 contiguous with ocelli and mandibular base. Antennae hardly longer 

 than half body, unusually stout and filiform throughout, with only forty- 

 five flagellar joints. Scutellum except centrally, and four indistinct nieso- 

 notal longitudinal lines, obsoletely flavidous ; metathorax dull and closely 

 shagreened, its basal transcarina strong but the apical indicated only at 

 apophyses. Third abdominal segment distinctly constricted basally.
