Campoplex] BRITISH ICHNEUMONS 81 



Instantly recognised by the lUTvrllus being geniculate or intercepted 

 distinctly above its centre and a little postfurcal. 



Described from Germany by Forster, and found in Sweden by Holm- 

 gren, It was introduced as British by l^ridgman (Tr. Norfolk Naturalists' 

 Soc. 1894, p. 619) and said by him to have been captured by Thouless at 

 Market Drayton in Norfolk. I have seen nothing like it.

A black species with the abdomen centrally rufotestaceous, second 

 segment basal ly black, legs partly red or in (^ mainly stramineous ; and 

 the impressed frons with scrobes auriculate. Mesopleurae strongly j)unc- 

 tate, finely alutaceous and feebly nitidulous; metathorax but slightly im- 

 pressed, densely grey-pubescent, with obsolete basal areae. Abdomen 

 with the second to fourth segments except basal mark on former red, or 

 in (5 fulvidous ; black lateral lines on third elongate ; basal segment 

 with small but distinct lateral foveae; terebra short, w'ith valvulae narrow. 

 Legs of V with apical half of the front femora, their tibiae and tarsi 

 fulvous, intermediate femora apically and their tarsi partly concolorous ; 

 legs of (J mainly flavescent with anterior coxae basally, hind coxae and 

 trochanters and femora black with base and apex of their tibiae piceous. 

 Wings with the areolet petiolate and not broad, emitting recurrent nervure 

 nearly from its centre. Length, 8-10 mm. 



Known by the strongly impressed frons, the elongate lateral black lines 

 of the third segment and the extension of rufescent colouration on the 

 second ; but especially by the auriculately elevated antennal scrobes, 

 which resemble those of certain species of Tryphon.
