132 BRITISH ICHNEUMONS. 



white-banded ; of 3 ferrugineous or piceous, the scape white beneath. 

 Thorax stout, 5 with the pronotum and often a callosity beneath the radix 

 red ; S with callosities before and beneath the radix white ; areola rect- 

 angular, a little longer than broad, apically emarginate. Scutellum flat, 

 quite glabrous and shining, yellowish white; of S punctate, very rarely 

 black. Abdomen black ; of ? hardly ever red-marked, segments six and 

 seven only white-marked ; of <S sub-linear, segments two and three often 

 more or less badious, the apical margins always red ; post-petiole acicu- 

 late ; gastrocaeli norma], somewhat deep ; S vvith intervening space 

 strongly aciculate and third segment quadrate. Legs black ; 9 with 

 tibiae and tarsi for the most part red, scopulae distinct ; ^ with anterior 

 coxae often white-marked, anterior tibiae laterally and hind ones basally 

 stramineous ; tarsi reddish or flavidous, fuscous apically. Wings slightly 

 clouded, stigma fulvous or rufescent, tegulae black with a red margin. 

 Length, 10-12 mm. 



The antennae strongly compresso-dilated in the middle ; coxal tufts 

 distinct ; middle or nearly the whole of the tibiae red, will distinguish the 

 $ from that of /. molitorius, and the continental /. Iwevigeiia, Thom., 

 which latter has no coxal tufts and its cheeks abbreviated. 



Holmgren mentions a peculiar variety of the $ , which has the meso- 

 thorax red-lined, and the first two segments entirely red, the third black, 

 with a red mark on either side. The S much resembles /. cotifusorins in 

 colour, but may be known by the darker under-side of the fiagellum, 

 whose joints are longer beneath, five to fourteen bearing short raised lines, 

 the apical margin of the clypeus is black above, rotundately truncate, and 

 segments two and three are more coarsely punctate. 



Stephens records this species as not very common, in June, at Birch 

 Wood and from the north of England. Parfitt says it is common and 

 generally distributed in Devon, though Bignell did not there meet with 

 it, nor does Bridgman mention it in Norfolk. It has been bred from 

 Orgyia pudibunda on the Continent, where it extends from France to 

 Sweden and Russia, and is found in pastures, woods and meadows ; the 

 female is said to hibernate among moss.

 obscurely red, apically black, never whitish ; hind coxae without scopulae.
