68 BRITISH ICHNEUMONS. 



punctate-scabriculous, and the gastrocaeli almost wanting ; the terebra is 

 one third the length of the abdomen. Legs black ; front femora and 

 tibiae dirty red somewhat infuscate externally, the intermediate rufescent 

 or fuscous, and the hind ones black. Wings a little clouded ; stigma red. 

 S . Head with the clypeus, face and mouth-parts white ; apex of the 

 mandibles black. Antennae sub-nodulose, black above, with an entire 

 white central band ; remainder of flagellum sometimes ferrugineous be- 

 neath ; scape beneath white. Thorax black ; areola transverse, semi- 

 hexagonal ; metathorax short, apically sub-bidentate ; spiracles similar to 

 those of 9 . Abdomen narrower than the thorax ; petiole black, with 

 distinct carinae ; post-petiole centrally rugulose ; from the apex of second 

 segment, whose gastrocaeli are almost absent, to the fifth or sixth is more 

 or less red, the remainder becoming darker to the apex ; or, rarely (var. 

 obsciirior, Berth.), the abdomen black, with the margins of the segments 

 castaneous. Legs black ; the anterior pairs being more or less red. 

 Length, 10-12 mm. 



The $ may be known by the coarsely punctate post-petiole and im- 

 maculate frontal orbits ; the $ by its black thorax and head, the latter 

 having the face and clypeus white, and by its broadly white-banded 

 flagellum. 



This would appear to be an uncommon, though widely distributed, 

 species on the Continent, and Bridgman did not meet with it in Norfolk ; 

 Stephens, however, records the $ from Scotland, Shropshire and Darenth 

 Wood, in June, " apparently scarce " ; it is probably commoner in the 

 south of Britain. Bignell has taken this species at Ivybridge, in Devon, 

 on 20th May ; it has not been bred.

$ . Head black ; palpi, mandibles, two marks on or whole of clypeus, 

 the frontal and sometimes the vertical orbits, red. Antennae somewhat 

 stout, filiform throughout, and centrally white-banded, generally with the 

 scape red below. Thorax with a callosity before the radix, and generally a 

 line below the scutellum, red ; metathorax somewhat scabriculous, with 

 only three upper areae, of which the areola is semi-circular and apically 

 incomplete ; spiracles short, elliptic. Scutellum apically red. Abdomen 

 red, with the first segment except its apex black ; central areae of post- 

 petiole finely and very closely punctate ; second segment closely punctate 

 with obsolete gastrocaeli; terebra one-third to two-fifths the length of 

 the abdomen. Anterior legs red, the femora somewhat darker and the 

 coxae sometimes black ; hind ones fuscous, tibiae becoming ferrugineous 

 towards their base ; tarsi sometimes with their onychii red. Stigma and 

 tegulae red. 



c^. Head black ; palpi, labrum, clypeus, cheeks, face and frontal orbits, 

 white. Antennae not pale-banded ; scape white, and funiculus fulvous, 

 beneath. Thorax black, with usual marks at the radix, generally the sides 

 of the pronotum and two large pectoral marks, white ; the metathorax
