BRITISH ICHNEUMONS. 157 



first flagellar joint twice longer than broad, the sixth quadrate ; in c? rather 

 slender and strongly attenuate Thorax black, mesonotum of ? entirely, 

 or with two longitudinal vittae, red ; metathorax not bidentate, some- 

 what scabrous, with three upper areae, of which the areola is quadrate 

 or slightly longer than broad in $, transverse in S. Scutellum and 

 post-scutellum usually dull red ; the former convex. Abdomen black, 

 segments two and three red ; apex of one also red, and six and seven 

 white-marked in ? ; post-petiole finely and distinctly aciculate ; gastrocaeli 

 transverse, intervening space slightly narrower than centre of post-petiole. 

 Legs red ; femora often in part, hind ones except extreme base, as well as 

 hind tibiae and tarsi apically and all the coxae, black. Wings sub-hyaline, 

 darker in $ ; stigma flavo-stramineous, of c? black ; areolet broad above. 

 Length, 7-8 mm. 



Differs from /. stigmaiorins in the stouter and sub-filiform antennae of 

 the ? ; the head more distinctly impressed behind the ocelli ; the ? areola 

 quadrate, or sometimes slightly longer than broad and the post-petiole 

 much more finely and distinctly sculptured. The colour of the $ abdo- 

 men is similar to that oi I stig/natoriiis, but the head narrowed behind the 

 eyes, less narrowed towards the mouth, the more sparsely punctate cheeks, 

 larger scutellum and much smaller spiracles render it distinct. The colour 

 of the legs varies considerably. 



/. rubedinis, Desv., which Berthoumieu incorrectly refers to /. ochropis, 

 is nothing but a rather profusely red-marked form of this species, having 

 the face and frontal orbits rufescent ; the first seven flagellar joints, two 

 longitudinal mesonotal vittae, and a callosity before the radix, always red. 

 The fourth abdominal segment is clear red, and the two following some- 

 what infuscate. The are five 9 ? i'l the British Museum from Desvignes' 

 collection, three of which are labelled " September, Ireland." 



Hardy first recorded this species from Britain on the strength of several 

 specimens found by Bold, one of which is in Marshall's collection, in the 

 Cheviot Hills, &c., in May and June {cf. Proc. Berwick. Nat. Club, vii. 

 p. 154 at Ent. Ann. 1874, p. 142). It has also been taken by Cameron, in 

 Scotland, and by Champion, in Ireland, which is probably the southern 

 limit of its range (Trans. Ent. Soc. 1889, p. 410). Mr. Malloch has given 

 me this species, which he found at Bonhill ; and Mr. Evans has taken it, 

 in March, beneath a stone, probably hibernating, on the summit of Car- 

 nethy, in the Pentlands, at an altitude of 1880 feet. It is evidently quite 

 a northern species, since Holmgren says it occurs in grassy places and 

 forest undergrowth in northern Sweden, and it is only elsewhere found in 

 Lapland and Russia. 



[/. haernatonotus, Wesm., which Marshall, in Ent. Ann. 1874, gives as 

 a doubtful synonym, is a distinct species {cf. Holmgr. Ent. Tidsk. 18S0, 

 p. 78), differing in its stouter structure and antennae, which are also 

 obviously filiform, thicker legs and different coloration.]
