Phygadeiion:\ BRITISH ICHNEUMONS. QI 



It should further be noted that the basal segment is always black to its 

 apex, which is not strongly explanate, with the post-petiole very strongly 

 and evenly aciculate throughout ; it is the petiole which is riniose ; the ? 

 antennae are two-thirds the length of the body, generally with the four 

 basal flagellar joints and part of the scape fulvous : I have seen no example 

 with the central joints i)aler, which character would point to affinity with 

 j\/icrocry/^/us ; the tercbra is nearly as long as the basal segment, the 

 wings are comparatively somewhat small and sub infuscate, and the legs 

 are very variable in colour. 



An abundant species both here and abroad ; I have records from early 

 June to the beginning of September, but it is commonest in July and 

 August on .l/igc/iai flowers. llickleigh (Bigncll); Urundall, in May 

 (Hridgman) ; New Forest and Offchurch IJury, near Leamington (Cliitty) ; 

 Abinger Hammer (Butler) ; Felden (Piffard) ; Kingsdown and Ri[)ple, 

 near Dover (Sladen) ; Sutton Coldfield (W. l">llis) ; both sexes at Redland, 

 near Bristol (Charbonnier) ; Deal in May and Greenings (W. Saunders) ; 

 Shere (Capron) ; Scarboro' (Elliott) ; Tostock and Benacre Jjroad (Tuck) ; 

 Lincoln, a $ attracted to artificial light in garden (Musham). It has 

 occurred to me on bushes in woods, especially on oak and birch, on 

 flowers of Chaerophyllum, and in greenhouses, at Ryde, New Forest, 

 Blean Woods in Kent ; at Ipswich, Felixstowe, Bentley Woods, Eye, 

 Foxhall, Dunwich, Tuddenham Fen, Brandon and Farnham in Suffolk. 

 In Dover, on 27th April, 1896, I took a very early $ on a house window. 

 Giraud once bred it from Stratioinys Ca/neleon, but it probably also preys 

 upon much commoner Diptera.

Head black, with the palpi white and the mandibles red-marked ; clypeus 

 sub-discreted, with the basal foveae and apical teeth very distinct ; genal 

 costa continuous, eyes glabrous ; face of c^ with dense white (jubescence. 

 Antennae of $ with the basal half of the flagellum and the scape beneath 

 flavidous ; of $ with the post-annellus rufescent beneath and hardly 

 longer than the scape, which is white beneath. Thorax immaculate, pro- 

 notum not punctate ; metathorax sub-nitidulous, not rugosely punctate, 

 with complete areae ; areola transverse and basally rounded, petiolar area 

 discreted ; apophyses small, spiracles imperfectly circular. Scutellum 

 black. Abdomen ovate, deplanatc, as broad in 9 ^^ the thorax, nitidu- 

 lous ; flavidous, with the first segment piceous and longer than the 

 terebra, slender and elongate ; sometimes the central segments laterally, 

 and always anus of 6, infuscate; post-petiole a little longer than broad, 

 only Slightly broader than the petiole, sub-carinate, centrally de[)lanate 

 and glabrous. Legs normal, flavidous ; hind tarsi, with base and apex of 

 their tibiae, infuscate ; 6 with the anterior trochanters while. Wings 

 slightly clouded ; radix white, tegulae piceous ; basal abscissa of the radial 

 nervure shorter than the breadth of the stigma, and about one third 

 shorter than the apical abscissa. Length, 4-5 mm.
