go BRITISH ICHNEUMONS. 



with valvulae white. Stigma piceous ; tegulae black, often white-dotted ; 

 areolet narrowly open above. Length, 10-12 mm. 



This species is rendered distinct by the post-petiole being evidently 

 carinated, its central, which is hardly broader than the lateral areae, 

 coarsely punctate, and by its obvious thyridii and gastrocaeli ; the colour 

 is also characteristic ; scutellum black in ? , apically white in the male ; 

 the femora and tibiae black, the front, or in the male, the anterior ones 

 being laterally stramineous ; the abdomen has the sixth and seventh seg- 

 ments, in both sexes, and the male valvulae white. 



Westmael, in his " Tentamen," mentions a variety of the male, which 

 appears to be unique, certainly Holmgren did not meet with it ; this has 

 the second and third segments black, and the apical angle of the first 

 white. Gravenhorst records a male with an entirely white scutellum. 



Hope took one of the original specimens near Netley, and Stephens 

 probably found it occasionally, in July and August, about London and 

 in Salop. I know of no British records since his day, excepting the follow- 

 ing. It should, however, be not uncommon at least in the North in grassy 

 places and among undergrowth, since in such situations it is not infrequent 

 in Sweden. An example in Mr. Beaumont's collection was captured at 

 Lewisham, in Kent, in August ; and Mr. Adkin has bred three females of 

 this, which is said to be " one of our handsomest species of Ichneumo- 

 nidae" from larvae oi Eiipithecia helveticata {cf. Proc. S. Lond. Soc. 1896, 

 p. 82). It is recorded from Essex.

Very like the next species, but smaller ; the puncturation close and fine 

 throughout. Llead black ; 5 with palpi and mandibles red, and a lunate 

 vertical dot white ; S with the palpi, sides of clypeus, of face to vertex, 

 and part of external orbits, white. Antennae black, feebly but elongately 

 attenuate, somewhat pointed, compressed and rufescent towards apex ; of 

 $ white-banded, S flagellum fulvous or ferrugineous beneath, with scape 

 immaculate and joints of apical half sub-nodulose. Thorax black, callosity 

 beneath radix usually white in ? ; (^ with callosity beneath and a longer 

 or shorter line before the radix, and pronotum, white ; upper metathoracic 

 areae complete, the costulae not strong ; areola sub-glabrous, semi-elliptic 

 or sub-hexagonal. Scutellum flat, of ? entirely black or apically rufous, 

 of $ with apical half white. Abdomen black, somewhat dull, closely 

 punctate and haired, the four basal segments red ; ? with sixth trans- 

 versely marked at apex, with seventh entirely, white ; of $ sub-equilateral, 

 petiole or first segment except apex, and fourth or fifth, with whole anus, 

 black ; post-petiole punctate, carinae not strong ; gastrocaeli large, deep 

 and strongly oblique, the intervening space being narrower than centre of 

 post-petiole and punctate, those of $ less deeply impressed. Legs with 

 anterior femora distinctly inflated ; black, femora and tibiae red, the pos- 

 terior apically black at least above ; front femora sometimes broadly 

 black ; coxae occasionally a little fulvidous beneath. Wings slightly
