Tryphon] BRITISH ICHNEUMONS. 183 

With us 7. ephippium is not very common, but extends from the Scots 
highlands to Kent, from 3rd July to 30th August only, in my experience. 
It was introduced by Bridgman (Entom. 1880, p. 54) and taken by him at 
Lakenham and Eaton in Norfolk: no one has subsequently noticed it in 
Britain. Most of my specimens were also captured in Norfolk, where 
Wainwright found it commonly in August, 1900, at West Runton; and I 
took it three years later about Cromer and Metton on flowers of /leracleum 
sphondylium. Tuck has occasionally met with it in Suffolk at Tostock. 
My other specimens are from Guestling in Sussex (Bloomfield); Dover 
and Ripple (Sladen); Shere (Capron); Ravenscar (Bingham); near Lon- 
don (Stephens); Nairn (Yerbury); and Banchory (Elliott).

Shining, punctate and black with the mouth, clypeus and facial mark 
flavous. Head hardly constricted posteriorly; upper margin of scrobes 
auriculately dilated; frons mutic, carinulate, deeply impressed and 
rugosely substriate ; face coarsely punctate, with at least a fascia or trans- 
verse mark flavous ; clypeus sparsely punctate, ferrugineous and apically 
rounded. Antennae filiform, flavidous beneath. Thorax stout, coarsely 
punctate with infuscate pubescence; metanotum somewhat smooth, cos- 
tulae wanting, areola elongate, narrow subparallel-sided and somewhat 
smooth. Scutellum subelevated, margined to beyond its centre. Abdomen 
red, with its base alone black; basal segment somewhat narrow, apically 
glabrous, with carinae extending to its centre. Legs stout and black with 
apices of femora, the anterior tibiae and tarsi, red; hind tibiae testaceous 
towards their base ; anterior coxae and trochanters only partly flavous. 
Length, 7—11 mm. 
Extremely like 7. /rochantera/us and, with it, known from the remain- 
der of the genus with auriculately elevated scrobes by its pale face. I 
have seen the type of 7. quadratus. 
This species is much less frequent than is generally supposed and there 
is something curiously spasmodic about its appearance that will not be 
explained till its hosts are known ; I did not see it between 1900 and 
1903, and between 1903 and 1908, though common in the years named ; 
nor has it occurred to me since. It is found almost invariably upon the 
flowers of Daucus carota and Heracleum sphondylium from the time the 
latter first blossoms on 12th June till 25th July, though rarely also taken 
by sweeping grass and reeds, usually in open fields and hedges. It extends 
probably throughout Europe and is recorded from Dorsetshire, Norfolk, 
Cambs. and Sussex, though apparently rarer in the west where Marshall 
and Bignell did not find it. My fifty specimens are from Hampshire 
(Miss Chawner), Surrey (Capron), Herts (Piffard), Gloucester (Charbon- 
nier), Suffolk (Tuck), London (Brunetti), Shropshire (Hope), Lincs. and
