146 BRITISH ICHNEUMONS. lOniorga 



(Burgst), and frt'cjuent in Belgium during May to July (Tosq.). In Britain 

 it has been bred from Elmlca sambuailis, Sciaphila virgaiireana , Pejiihina 

 gdi/ianatia, N^ofocelia Udmajiniana (Entom. iS8i, p. 140) ; Tortrix rosana, 

 aTortricid larva on Lithospermum, GmphoUiha Pavkulliana, Ephippiphora 

 foencana [I.e. 1883, p. t»6) ; E. scutiilana or A\ Pflugiana [I.e. 1884, p. 67) ; 

 from PL nigrocostana on 19th May in Devon (Bignell) ; and very doubt- 

 fully from Chrysophamis dispar (E. M. M. 1903, p. 148). It is a common 

 species about Norwich and, indeed throughout the country, though 

 apparently rarer in the northern counties. I have it from Bristol, Bath 

 and Taunton (Charbonnier), Malvern (Gorham), Chiswick (Sich), Milford 

 Haven (Andrews), Tostock, Shere, Greenings; Whittle has bred the 

 female at Southend from Bacotia hetidina and Clutten from an unknown 

 host at Burnley, both in July; on loth July, 1901, I saw females sitting 

 commonly on oak trunks, upon which were Paedisca corticana in abund- 

 ance, in a wood at (Jxshott in Surrey. Elsewhere it has occurred to me 

 at Barton Mills, Bramford, Monk Soham, Southwold and Ashfield in 

 Suffolk; Lyndhurst and Matley Bog in the New Forest; Newport in Isle 

 of Wight; Boston and Eouth in Line, and very commonly at Ryde in my 

 father's garden during August.

Black with femora and tibiae and anterior trochanters red, mouth and 

 tegulae and ventral plica pale, and the underside of scape usuall}- whitish; 

 (5 with anterior coxae also pale. Head transverse and somewhat con- 

 stricted posteriorly, with palpi and mandibles except apically flavidous. 

 Scape with a flavidous dot beneath. Metathorax somewhat more strongly 

 excavate than in O. difformis, with its costae strong. Abdomen with only 

 the ventral plica dull flavidous ; postpetiole laterally rounded, and double 

 breadth of petiole ; second segment a little longer than broad, and third 

 transverse ; terebra rather more than half length of abdomen. Legs red 

 with all the coxae except anterior of $, and only the hind trochanters 

 black ; hind tarsi infuscate. Wings subinfumate, with stigma piceous 

 flavous and tegulae stramineous. Length, 5-7 mm. 



The subexcavate metathorax, subinfumate wings and nearly angulated 

 cubital nervure distinguish this species which, together with the two 

 following, is recognised by having the mesopleurae not very closely 

 though obviously punctate, the metathorax subexcavate and stout costae, 

 the terebra almost longer than half abdomen, the nervellus evidently geni- 

 culate and ventral plica not nigrescent. 



1 propose to here treat O. siihmarginata as a variety of the present 

 species, since its author himself was very uncertain of its right to specific 

 rank, though it differs somewhat materially in having the scape, tegulae 

 and mandibles immaculate black, and the hind tibiae darkly bicingulate : 

 " Mr. Fletcher has bred three females and two males from Eupithecia 

 pygniacata from Cambridgeshire."
