242 BRITISH ICHNEUMONS. [Luryproctus 

exhibited from Oxshott in July, 1893 (Meeting S. Lond. Ent. Soc., March 
8th, 1894); Lands End (Marquand); Boxhill early in August, 1898 
(Beaumont) ; several at Shere (Capron); Barr in Ayrshire, during the 
latter half of July, 1899 (Dalglish). I took several about Ipswich in 1894, 
but did not again meet with it till 1905, when a male occurred upon 
Angelica sylvestris flower at Barton Mills, Suffolk, at the end of August. 
It appears impossible to separate £. regenerator from the typical form of 
this species upon any grounds but its mainly red hind femora, both 
basally and apically black in Grav.’s example and castaneous in one or 
two of my own; both Holmgren and Thomson failed to detect further 
distinctions ; its distribution seems co-extensive, and Brischke has bred 
it (Schr. Nat. Ges. Danz. 1871, p. 68) from the same host. I have seen 
two British females in Mus. Brit. 
3. alpinus, Holmgr. 
Euryproctus alpinus, Holmgr. Sv. Ak. Handl. 1855, p.110, ¢. 
Somewhat shining and finely punctate, with body mainly red. Head 
hardly constricted posteriorly ; mouth, clypeus and the face, except a cen- 
tral longitudinal line and another across base of clypeus, flavous. 
Antennae filiform and tricoloured; scape flavous beneath; flagellum 
broadly rufescent and centrally white-banded. Thorax immaculate ; 
metanotum nitidulous with areae distinct, though costulae wanting ; 
areola not very narrow, apically incomplete. Abdomen centrally broadly 
red ; basal segment slightly arcuate, with postpetiole gradually explanate 
apically, and thrice breadth of petiole; valvulae exserted. Legs black 
with the tarsi, tibiae and most of the anterior femora, red; hind tibiae 
apically black; hind tarsi centrally white-banded. Wings normal ; 
areolet wanting ; nervellus intercepted above its centre. Length, 9 mm. 
3 only. 
Very like Z. nemoralzs, but differing in its capital colouration, meta- 
thoracic structure, wanting areolet and more shining metanotum. It was 
thought by Thomson (O. E. xiii. 1435) to probably be synonymous with 
L. albipes, Holmer., but since he here erroneously also synonymised £. 
fuberculatus, Holmger., we are justified as considering it at least temporarily 
as distinct. 
I regard this species as doubtful, both in respect of its distinction from 
E. nemoralis which is slight and secondly as truly indigenous, since it 
entirely rests upon a ¢ correctly here placed by Desvignes in his own 
collection, now in Mus. Brit. It has only been found in Belgium and 
France since Holmgren first recorded it from Tarna in southern Sweden 
on 1st August.

Head dull and a little constricted posteriorly ; palpi often stramineous, 
mandibles usually centrally fulvous; frons slightly impressed on either 
side, face subdeplanate, cheeks narrow. Antennae not white-banded ; of ¢ 
infuscate, rufescent below with scape usually black; of 9 fulvous and
