BRITISH ICHNEUMONS. 223 



us, since it has been found at Cann Quarry, in South Devon, early in 

 September ; in Essex ; at Church Stretton, in September, and York, in 

 October ; about Lynn, and bred from Cabera pusaria, in Norfolk ; Ely ; 

 Raynor has bred it from Ypsipetes impluviata ; Mr. A. Adie Dalglish has 

 given me females, from Irvine, in Ayrshire, early in September, and 

 Bishopton, in Renfrew, in early July. I have swept the male, from swamps, 

 at Horning, in Norfolk, as early as June 15th, and taken the female, ui)on 

 Myrica gale, at Matley Bog, in the New Forest, in August.

Head black, narrowed behind the eyes ; frons very finely punctate, 

 shortly canaliculate or foveate centrally ; clypeus sub-truncate ; cheeks not 

 buccate, sinuate near mandibles; internal orbits stramineous \ $ also with 

 apices of the cheeks, sometimes the external orbits or the whole face and 

 clypeus, pale. Antennae long, slender, setaceous, not dilated nor centrally 

 incrassate ; of $ centrally white-banded, with the sixteenth flagellar joint 

 sub-quadrate ; scape of $ flavous beneath. Thorax black, of $ and some- 

 times $ with pale callosities at the radix ; areola usually transverse \ costulae 

 and apophyses wanting ; coxal area entire ; spiracles elongate. Scutellum 

 laterally carinate nearly to its apex, black ; sometimes centrally or apically, 

 and also occasionally the post-scutellum, whitish. Abdomen sub-elliptic, 

 black ; petiole somewhat short, of normal breadth ; post-petiole obsoletely 

 carinate, more or less finely rugose or sub-glabrous ; gastrocaeli of normal 

 breadth and depth, the intervening space rugosely punctate. Legs normal, 

 red ; coxae, trochanters and tarsi black ; hind tibiae sometimes apically 

 infuscate. Wings hyaline : stigma dark ; areolet convergent, or coalesced, 

 above. Length, 8-10 mm. 



The variety iridipennis, which Thomson considered a good species, and 

 which, indeed, seems to have as good a claim to distinction as the follow- 

 ing, differs in its smaller size, and in always having the lines before and 

 underneath the radix, the scutellum and post-scutellum flavidous ; but 

 especially in its convex frons, larger eyes, short lateral scutellar carinae, 

 which hardly reach the centre, smaller spiracles and longer terebra ; the 

 $ , moreover, has the anterior coxae flavidous. 



It should be noted that the present species has the head narrowed be- 

 hind the eyes, the genal costa anteriorly sinuate and the frons but finely 

 punctate ; the mesonotum is nitidulous ; the stigma is pale, or, in the c?, 

 nigrescent; the abdomen is black, with the incisure of the second segment 

 usually rufescent, its thyridii are oblique and somewhat deeply impressed, 

 and the third is transverse ; the hind tarsi are not incrassate, and the 

 apices of their tibiae, and sometimes also of their femora, are infuscate ; 

 the face of the S is variable in colour, but often has tlie internal orbits, 

 sides of the clypeus and two dots beneath the scapes, flavidous. 



Several continental species are extremely closely allied. /'. pedatorius
