208 BRITISH ICHNEUMONS. 



Head black ; ? with palpi, mandibles, frontal, vertical and external 

 orbits as well as the sides of the face and of the clypeus, broadly flavous, 

 frons coriaceous, clypeus discreted, scrobes large ; 6 with cribrary organs, 

 face, cheeks and frontal orbits, flavous. Antennae black, with scape 

 flavidous beneath; of $ somewhat slender, broadly flavous-banded, of 3 

 sub-dentate, usually with joints eleven to nineteen flavous above. Thorax 

 stout, black with pronotum and lines before and beneath radix, and some- 

 times two dentiparal patches on the metanotum fulvous or flavous ; all the 

 pleurae sometimes broadly flavous in $ ; areola sub-quadrate or transverse, 

 apically slightly emarginate ; petiolar area equilateral, its costae strong and 

 apically sub-dentate, costulae obsolete. Scutellum convex, fulvous or 

 flavous. Abdomen sub-elongate, black ; first two or three segments 

 broadly flavous at their apical angles ; second to fourth ventral segments 

 at least centrally flavous and plicate ; post-petiole glabrous, with a few 

 scattered punctures, often centrally foveate ; gastrocaeU normal, some- 

 what deeply impressed and striate. Legs normal, elongate, black, with 

 posterior tibiae and tarsi sub-tomentose ; anterior coxae and, in 3 front 

 legs entirely, flavous ; posterior femora partly, tibiae except at base, coxae 

 and trochanters occasionally, flavous-marked ; tarsi flavous with apices of 

 the joints fulvous. Wings a little clouded ; radix flavous, tegulae piceous ; 

 stigma fulvous. Length, 15-17 mm. 



The extent and distribution of the flavous markings are most distinctive. 



This lovely species, Stephens says, has been taken about London, in 

 June ; and Marquand records it, in 1884, from the district of Land's End; 

 Essex ; there are three ancient males with no data in Marshall's col- 

 lection ; I have recently received a female, captured in Cornwall, by Mr. 

 E. C. H. Davies, in 1902. On the Continent it extends from Belgium, 

 through central Europe, to Russia ; but has not, I think, been bred. Mr. 

 Davies adds : — " The example I took w^as resting on a road, upon high 

 ground, in the parish of St. Ervan ; it appeared to be perpetually shivering 

 all over in a very venomous way, which, with its colour, was most repellent ; 

 it, however, allowed me to capture it with my fingers without any attempt 

 at flight."
