124 BRITISH ICHNEUMONS. 



glabrous, with scattered punctures, somewhat rounded apically ; cheeks 

 normal. Antennae setigerous, distinctly attenuate towards apex ; fulvous, 

 centrally darker and scape black above. Thorax entirely black and finely 

 punctate ; mesosternum more sparsely punctate with sternauli indicated ; 

 metathoracic areae distinct and complete ; areola rectangular, a little 

 longer than broad ; juxta-coxal carinae strong. Scutellum slightly convex, 

 closely punctate ; black. Abdomen sub-cylindrical, convex, closely and 

 finely punctate, dull throughout; red, with centre of first segment, and from 

 fifth (except its base) to apex, black ; post-petiole indistinctly aciculate, 

 carinae strong ; gastrocaeli normal, thyridii not deep ; intervening space 

 sub-aciculate, not broader than centre of post-petiole ; ventral fold on 

 segments two to four ; valvulae retracted, small. Legs red ; coxae ex- 

 ternally, apices of hind femora, of hind tibiae, and of the tarsal joints, 

 black. Wings flavidous-hyaline ; areolet pentagonal ; tegulae and stigma 

 flavous. Length, 9^ mm. 



This little-known species has been ranged by Berthoumieu with those 

 appertaining to Barichnejinion, from which it appears to be abundantly 

 distinct, firstly in its aciculate post-petiole and secondly in the normal 

 gastrocaeli of the S , if not of the ? . The vertical orbits of the latter are 

 red, as is sometimes the case in Ichneunion, and not flavous as in Barich- 

 7ieumon ; but I have seen no example of the female, and assign the present 

 position to it mainly upon the male characters. 



Schmiedeknecht says the 9 is very like and " vielleicht identisch " Ich- 

 neumo?i inustela, Kriech., which, however, has the post-petiole smooth and 

 the gastrocaeli very large and deeply impressed. 



The male has not before been described ; there is one example in the 

 British Museum, named probably by Wesmael himself, whence the above 

 description is drawn. This is the only indigenous specimen of which I 

 am aware. On the Continent the female is recorded only from Holstein.

The centrally badious or black abdomen of this and the next species is 

 distinctive. Head black, immaculate, or orbits rarely reddish, in ? ; $ 

 with palpi and mandibles partly pale, the face and clypeus entirely or 

 laterally, and the frontal orbits flavous ; cheeks normal, almost smooth 

 apically. Antennae strongly explanate centrally, gradually attenuate to- 

 wards apex, fourth joint quadrate ; ? white-banded, $ scape flavous- 

 marked and flagellum more or less red beneath. Thorax stout, black ; 

 immaculate in ? , (^ pronotum and two callosities at radix flavous ; meta- 

 thorax with three upper areae only ; areola quadrate or slightly longer 

 than broad, apically emarginate ; $ pubescence long and whitish. Scu- 

 tellum flat, somewhat convex in $ ; smooth, entirely flavous-white, some-
