Head short, black, cheeks somewhat buccate ; palpi, the bidentate 

 mandibles, sides of truncate clypeus, and the internal orbits, ferrugineous 

 or flavous ; $ with temples grey-haired, and its broadly rounded clypeus 

 and face for the most part or entirely flavous. Antennae somewhat slender, 

 setaceous, black ; of $ fiavous-banded and basally red with the fourth 

 flagellar joint quadrate ; scape of ? ferrugineous, of ^ flavous, beneath. 

 Thorax black, pronotum sometimes red in $ or with two flavous dots in 

 $ , usually also with concolorous lines before and beneath the radix ; 

 areola sub-quadrate, broader in (J ; costae weak, costulae sub-obsolete ; 

 metathorax sub-mutic. Scutellum, and in ^ often post-scutellum, flavous. 

 Abdomen black with second and third segments red, often piceous 

 apically and fulvous basally ; the remainder not pale-margined ; post- 

 petiole closely and finely aciculate, laterally punctate ; gastrocaeli sub- 

 circular, of normal size and somewhat superficial ; extreme base of second 

 segment striate ; the c^ has the angles of first, base or sides of fourth and 

 the sub-truncate, depressed and nitidulous genital valvulae also flavous ; 

 second to fourth ^ ventral segments plicate, the ultimate not spinate ; 

 terebra slightly exserted, rufescent. Legs black ; $ with tibiae, except 

 the posterior towards their apices, and the anterior femora, fulvous or 

 rufescent ; ^ with tibiae, apices of front femora and often marks on the 

 anterior coxae, flavous. Wings flavescent-hyaline ; stigma, tegulae and 

 radix fulvous or flavous-marked. Length, 11- 15 mm. 



The seventh segment of the ? is often entirely rosy. The ^ resembles 

 those of the Ichneumon extensorius group, but the head is less narrowed 

 behind the eyes, the temples pilose, apex of clypeus broadly rounded, fla- 

 gellum immaculate, gastrocaeli much smaller, thyridii oblique, and the 

 structure of the genital valvulae is distinct. 



The var. oblongatus has the areola elongate, not transverse as in the 

 type, third segment sub-quadrate, and the apical margin of the first to 

 fourth flavous, the third and fourth being black-marked and margined. 



Gravenhorst noticed this species in July, on plants infested with Aphides 

 and Syrphid larvae, in August, on umbelliferous flowers, and records it 

 from Netley. It has been bred from Melitea maturna and Setina ramosa 

 on the Continent, where it occurs in France, Sweden, Germany, etc., and 

 in Britain from Mania iypica. Sladen has very kindly given me a female, 

 taken at St. Margaret's Bay, early in August ; and Bradley has found it, in 

 May, at Barmouth, which dates indicate its possible hibernation.
