ga BRITISH ICHNEUMONS. 



Head not narrowed behind eyes, black ; mouth parts piceous. Antennae 

 stoutish, scarcely longer than half body, black, slightly dilated and red- 

 banded centrally, apically attenuate, 'riiorax black ; pronotum and the 

 shining mesonotum red ; metathorax finely rugulose, with three upper 

 areae, of which the areola is quadrate ; their costae fine. Scutellum 

 sparsely punctate, shining, red. Abdomen elongate- ovate, black ; segments 

 one to three red, six and seven dorsally fulvous ; central segments trans- 

 verse; post-petiole smooth, obsoletely reticulate, nitidulous, slightly punctate 

 apically ; gastrocaeli transverse, broad, shallow, the intervening space nar- 

 rower than centre of post-petiole ; terebra distinctly exserted. Legs red ; 

 tarsi apically piceous ; hind coxae entirely black and not scopuliferous. 

 Tegulae reddish ; stigma testaceous ; areolet wide above. Length, 7 mm. 

 Male unknown. 



The stout antennae, broad head and shagreened post-petiole appear to 

 ally this species with Ban'chneio/ion in spite of the immaculate vertex. It 

 much resembles Ichneumon picticoUis, Holmgr., from which the colour of 

 the legs and the incrassate antennae distinguish it. 



Mr. G. C. Champion took one specimen, at Aviemore, in 1887. It is 

 unknown on the Continent.

A small black species, with the scutellum more or less white and the 

 abdomen mainly red. Head black ; clypeus discreted from the prominent 

 epistoma ; mandibles red-marked ; $ with frontal orbits distinctly white, 

 the colour being a little incurved along the epistomal costa which extends 

 to the eyes ; $ with mandibles, except their apices, the internal orbits and 

 centre of face, flavous. Antennae sub-filiform, black ; those of ? white- 

 banded, of $ ferrugineous, with the scape flavous below. Thorax black, 

 shining, a callosity beneath, and in $ before the radix, flavous; metanotum 

 sparingly rugose, with complete areae, areola cordiform, the apical angles 

 rounded and the apical margin gently curved, not emarginate ; petiolar 

 area discreted ; notauli punctiform ; sternauli distinct, reaching from apex 

 to centre of mesosternum ; spiracles rather small, linear or elongate-oval. 

 Scutellum flat, sparsely punctate, with erect setae ; apically truncate and 

 white, rarely black throughout. Abdomen red ; first segment, except its 

 apex, and most of the last three black ; the sixth and seventh narrowly 

 white- or red-margined ; post-petiole more or less strongly punctate, the 

 carinae indistinct and apex glabrous ; second segment punctate, sub-quad- 

 rate, with the gastrocaeli sub-obsolete and sub-striolate, the intervening 

 space being very broad and evenly punctate. Legs black ; hind tibiae, 

 which are internally canaliculate in c^, and more or less of the anterior legs, 

 red ; hind coxae without scopulae, their femora vary from red to piceous or 

 black. Wings slightly infuscate ; ? tegulae and stigma piceous, radix 

 flavous, areolet somewhat narrowed above. Length, 7-8 mm. 



The variation is confined to the colour of the female legs and scutellum. 



This small species forms, as Thomson has pointed out (loc. cit.), some- 

 what of a connecting link with the Phaeogenides, much resembling super-
