BRITISH ICHNEUMONS. 47 



rounded ; generally with the frontal and external orbits white-lined ; of $ 

 also with mouth and face entirely white. Antennae slender, setaceous, 

 black ; of ? rather more than half length of body, centrally white above ; 

 of S not reaching anus, scape white beneath. Thorax sometimes entirely 

 black ; usually with humeral callosities and post-scutellum white ; of 6 

 gibbulous, usually with pronotum, propleurae, and sometimes two marks 

 on metathorax also white ; areola sub-lunate. Scutellum sometimes with 

 a sub-apical white fascia, or in $ with the apex and the basal carinae white. 

 Abdomen of $ nitidulous, blue-black, apical margin of petiole centrally 

 white, of third and fourth segments with a glaucous-white dot ; incisures of 

 second and third ferrugineous ; of S with less blue reflection, very finely 

 and closely punctate, oblong-ovate ; five basal segments with their apical 

 margins entirely or in part white ; post-petiole aciculate ; base of second 

 segment with centre aciculate and narrower than the large and deeply 

 impressed gastrocaeli, which are not transverse ; apex immaculate. Legs 

 black : of S somewhat slender, with apices of all the femora white ; anterior 

 legs mostly white in front and a white dot at apex of hind tibiae : of $ the 

 anterior femora always, and the hind sometimes, with an apical white dot ; 

 front tibiae apically white ; hind tibiae not white-banded ; coxae not 

 scopuliferous. Wings sub-hyaline ; areolet sub-deltoid ; stigma and tegulae 

 piceous. Length, 12-15 '^i™- 



I have prefered to attach more importance to the peculiarly white knees 

 {cf. Wesm. " Otia "), than to the abdominal cinctures, which in some 

 specimens are entirely wanting, as are also the thoracic markings. The 

 colour of the scutellum is also most variable, the white markings being 

 sometimes entirely absent ; Gravenhorst's /. alboguttatus (?) is referable 

 to the latter form. 



This species is probably commoner in southern than in northern counties, 

 since it is not found in Scandinavia, though recorded from France, 

 Germany, Italy, &c. Stephens records it from the New Forest, very rarely, 

 in June. I know of no recent records, and it has not been bred.
