Ophion arcuatus Brullé, 1846: 146 . Status A very rarely collected species, found on southern coastal heaths where it has been reared from Lasiocampa trifolii (Denis & Schiffermüller, 1775) (Lasiocampidae) . The host is now very local and E. undulatus has not been found in Britain since 1971. Material examined ENGLAND : 1 ♀ , 1 Ƌ, Dungeness ( VC 15), ex Lasiocampa trifolii coll. as larva 6 Jun. 1945 (G. V . Bull) ( BMNH ); 1 ♀ , 1 Ƌ, Ilfracombe ( VC 4), Jul. 1971 (I.D. Gauld); 1 ♀ , Lowestoft ( VC 25), Jul. 1971 (I.D. Gauld) (latter two records taken from Gauld, 1974 ; specimens not in BMNH ). Additional material in NMS SPAIN : 1 ♀ , Zaragoza, Montes de Torrero, 230 m , 24 May 1998 (G.E. King). Remarks Enicospilus inflexus has been separated from E. undulatus on the basis of differences in head shape ( Gauld 1974 ) which seem to be consistent, based on the limited material in BMNH. Although there may be a difference in host use, this is based on only two rearings of E. undulatus , from one place and date; although Lasiocampa trifolii is rather smaller than L. quercus , E. inflexus and E. undulatus do not differ significantly in size.
