Euryproctus | BRITISH ICHNEUMONS. 241 

This species would appear very scarce in Britain and there are no 
records since its introduction by Desvignes in 1856 on the strength of the 
three unlocalised females in his collection, now in Mus. Brit. Abroad it 
is recorded from Silesia (Grav.), Sweden (Holmgren), Prussia (Brischke), 
3elgium (Tosq.), Switzerland (Kriech.) and France (Gaulle). With us it 
would appear confined to the south of England and I have only seen five 
females, three kindly given me by Miss Chawner from the New Forest, 
where she probably bred them from some Tenthredinid, one taken by 
Stanley Edwards during 1890 at Lynton in Devon, where Bignell did not 
meet with it, and another captured on the wing by Lyle on 29th Septem- 
ber, 1910, about Brockenhurst.

A somewhat shining and very finely punctulate species, with abdomen 
centrally red and both antennae and hind tarsi white-banded in both 
sexes. Head transverse, not constricted posteriorly and entirely black, 
or with @ clypeus rarely pale; face hardly protuberant; clypeus short, 
apically broadly rounded and sparsely punctate. Antennae centrally 
white-banded in both sexes, and with flagellum rufescent beneath both 
basally and apically. Thorax dull, evenly sculptured; metanotal areae 
distinct but costulae wanting. Abdomen broadly red centrally ; basal 
segment slightly arcuate, with usually prominent spiracles and the post- 
petiole gradually explanate apically, thrice broader than the long petiole ; 
both terebra and ¢@ valvulae exserted. Legs with the tarsi, tibiae and at 
least anterior femora red ; hind tibiae apically black and the tarsi white- 
banded in both sexes; tibiae distinctly spinulose. Wings with the dark 
stigma basally paler, areolet subpetiolate and triangular; lower basal 
nervure continuous or subpostfurcal; nervellus intercepted above its 
centre: Length, 7—94 mm. 
At once known by the white-banded antennae and hind tarsi in both 
sexes, combined with the centrally broadly red abdomen, very distinct 
areolet and strong central metanotal area. It is said to differ from £. 
crassicornis, ‘Thoms., in its more slender antennae, dark palpi and not 
antefurcal basal nervure ; Elliott took several examples, comprising both 
sexes of this form, which I cannot consider distinct, at Banchory in Kin- 
cardine during September, 1910. I know nothing of JZ. sudorbitalis, the 
type of which I fail to find in Stephens’ collection. 
The type form is not infrequent in southern Sweden, Germany, Bel- 
gium and France in June; and Brischke says (Schr. Nat. Ges. Danz. 
1878, p. 69) that he bred a variety from the cocoons of Zenthredo scalaris 
in Prussia. Stephens thought it somewhat common about London and 
in Shropshire in June, but the only specimen in his collection was 
representing the undescribed female of A/Zesolep/us arridens, Grav. It is, 
however, not very uncommon with us, though said to be rare when
