()phion^ BRITISH ICHNEUMONS. 267 



Tliis insL'L'l M'cuis vci) larr in llrilain, wluiici' il has iiul bcloru bucii 

 recorded. Fcinalcs, ayrceinj^- exactly with llie orit^inal description, were 

 bred with some doubt from a species of 'fotniocaiiipa in May, 1S94, by 

 W. Harrison and with e{]ual doubt in June, 1899, from Ainp/ivdtisis betu- 

 /aria at Lowestoft by Bedwell; Clutten sent me one cocoon from an un- 

 instanced Lepidopteron in April, 1910, whence another female emerged 

 during the following month ; and Esam has also given it me trom the 

 Hastings district. Elsewhere it is only known trom Hungary, where 

 Mocsary bred it from the Noctuid moth, Cirrhoidca {Cosmia) avibusta.

A not very pale testaceous species, with dilluse pubescence Head of 

 normal size with vertex not broad and temples not broader than eyes, 

 which are contiguous or subcontiguous with both ocelli and base of the 

 acutely bidentale mandibles. Antennae about as long as body, 57-62- 

 jointed. Scutellum not laterally carinate and rarely, with the thorax 

 never, clear flavous-lined. Areola wanting ; ba.sal transcarina of metano- 

 tum always distinct, the apical centrally interrupted by two more or less 

 distinct longitudinal carinae which extend to apex of the discreted petio- 

 lar area. Intermediate calcaria strongly inequal in length, and both the 

 hind ones linear. Wings hyaline, very rarely slightly flavescent towards 

 their base; stigma unict)lorous testaceous, not basally paler; nervelet 

 di.stinct, of variable K'ngth ; lower ba.sal nerviux- anlefurcal or continuous 

 through median; nervellus subopposite and intercepted centrally. Length, 

 15-22 mm. 



Known by the approximation of ocelli and mandibular base to eyes, 

 which are apically subconvergent internally, the apically acute mandibles, 

 mutic scutellum, somewhat narrow vertex, linear hind calcaria and uni- 

 colorous stigma. I believe the occasional anal infuscescence to be invar- 

 iably accidental and posthumous ; the whole insect will become black, if 

 allowed to rot in a confined space. 



Ophion Itilcus was known as iarl\- as 1O02, wlicn ( iiulart published his 

 IMelam. ».V' Hist. Insect., where it is ligured at plate .x.wvii ; and in 1710 

 Ray (Hist. Ins. p. 253) had recognised it as British. Its distributit)n 

 extends from India, whence 1 have seen it, to the Straits of .Magellan, 

 whence it was correctly recorded by Haliday (Trans. Linn. Soc. 1830, 

 p. 316; <■/. Entom. 191 1, p. 212); I possess it from .Saskatchewan and 

 Hutton records it (Cat. Dipt, etc., iX<S2) from New Zealand. 



Of this species, as iiere restricted, 1 have- a lumdrc-d examples: from 

 the New Forest (.Miss Chawner), in .May (Adams), wliere il has been 

 bred in 19 12 from Cymalophora ride fis and C jhiTieoriiis (Lyle); (luestling 

 (BloomHeld); Deal (Lyle); Rye, settled on a larva of the C..'urculii)nid, 

 I.ixus a/ginis in August (l)<3nisthorpe, 'I'r, Ent. Soc. 1907, p-45) ; South- 

 ampton ((jorham), Weymouth i^Peachell), IJristol (Charbonnier), West 

 Somerset in .May (Slater), I'lymouth (Keys), Redruth near Truro (.L. Smith);
