308 BRITISH ICHNEUMONS. [ Erromenus 

discal carinae extending beyond its centre ; terebra black and very shortly 
exserted. All the legs red with coxae and trochanters alone black or 
rarely badious; tibiae always basally flavescent. Wings with stigma 
black, radix and tegulae stramineous; radial nervure a little reflexed at 
base and apex; areolet irregularly transverse-triangular and petiolate ; 
nervellus intercepted below its centre. Length, 5—6 mm. 
The areolet is very rarely obsolete or wanting, and the anus (Grav.) or 
most of the abdomen (Brisch.) occasionally black. 
A common species from May to July in Germany, sometimes on um- 
beliferous flowers; Austria (Gravenhorst) ; not very common in central 
and southern Sweden (Holmgren); Belgium (Tosquinet) ; and France 
(Gaulle). It has not yet been bred, which is strange considering its fre- 
quency. In Britain, Stephens says it was found uncommonly near 
London in June; Marshall took it at Bugbrooke in Northants, and Bridg- 
man at Earlham in Norfolk. There are several in Capron’s collection 
from Shere in Surrey; Stenton took it at Herne Hill in June, 1909; it 
has often occurred to me by sweeping and on the flowers of Heracleum 
sphondylium in Suffolk at Tostock, Tuddenham Fen, Westleton pits, etc., 
from roth July to 19th August; and on 7th September, 1908, I took a 
specimen investigating a colony of Aphis crafaeg?, Kalt., ona whitethorn 
bush and sucking their honey-dew in my garden at Monks’ Soham,

Shining, punctulate and black, with the second or second and third seg- 
ments entirely red. Head a little constricted posteriorly ; frons sparsely 
punctate ; face closely punctate centrally ; mouth red. Antennae filiform 
and shorter than body. Thorax stout, pubescent, black and punctulate ; 
metathorax with five distinct discal areae, of which the areola is sub- 
quadrate and the lateral areae transverse. Scutellum discally subdeplanate 
and laterally margined to its centre. Abdomen subcylindrical, centrally 
fulvous with the apical margins of all the segments discally pale; three 
basal segments punctate, remainder smoother; basal segment a little 
convex, margined, strongly punctate, with carinae extending beyond its 
centre ; terebra very shortly exserted. Legs stout and red with coxae, 
trochanters and at least the basal half of anterior femora black; tibiae 
basally whitish ; hind femora black-marked basally only beneath. Wings 
with stigma and tegulae black, radix stramineous ; areolet irregular and 
subpetiolate ; radial nervure nearly straight apically; nervellus antefurcal 
and intercepted far below its centre. Length, 5—7 mm. 
I know nothing of this species. Gravenhorst possessed five examples 
from Piedmont, Austria, and umbeliferous flowers in August in Germany ; 
it appears to be rare in Sweden and is recorded from France by Gaulle. 
It was brought forward as British by Rev. T. A. Marshall in his 1870 
Catalogus but no one has referred to it since then, and it is not represented 
in his collection.
