252 BRITISH ICHNEUMONS. [ Luryproctus 

at Cheltenham, Govilon in south Wales, and Cornworthy in Devon. I 
owe a female from Giffnock, taken in June, 1899, to Mr. Dalglish’s 
generosity, and myself swept a male on 1st September, rg10, in a salt- 
marsh at Southwold in Suffolk. It had most probably been previously 
overlooked on the Continent, since Thomson records it not only from 
Sweden in 1895, but also from both France and Germany. 
NOTOPYGUS, Holmgren.” 
Holmgr. Sv. Ak. Handl. 1855, p. 115. 
This genus very closely resembles Luryproc/us in facies and all essential 
details; but may at once be known therefrom by the apically truncate cly- 
peus, unevenly impressed base of the often discally bicarinate second seg- 
mentand in having all the following in 9 distinctlyemarginate. I cannot tell 
why Marshall placed “chneumon sponsorius, Grav. 1820—a parasite of this 
name was first described by Fabricius in 1781, as Anomalon sponsorius by 
Jurine in 1807 and given by most of the old authors—under the present 
genus in his 1870 Catalogus; it was recorded by Stephens under JZeso- 
leptus as British in 1835, but omitted from Desvignes’ Catalogue; and I 
find the two representatives in Mus. Brit. are H'xvysfon cincfulum and £. 
brevipetiolatum, of the former of which Pfankuch tells us that Graver- 
horst’s type is a variety. For Marshall’s second species, cf. Ichn. Brit. 
ii. 251; but, correct as the synonomy there adopted appeared, Pfankuch 
has since found the type of 7. subrufus to be a malformed example of 
Tryphon consobrinus ; so Haliday’s name must stand for our Cryptid. Thus 
no WVo/opygus was known in Britain till 1882, when the following species 
was introduced. ‘Thomson says two species of this genus are probably 
parasitic upon Lyda. 
1. emarginatus, Holmgr. 
Notopygus emarginatus, Holmgr. Sv. Ak. Handl. 1855, p.115, ¢ ¢; Voll. 
Pinac- vill pl. cxxxietis. lochs Dhoms, Ol. sax. 1983: 
A black and somewhat nitidulous species with antennae white-banded, 
and most of abdomen and legs red. Head rounded posteriorly with cen- 
trally emarginate and not very broad vertex; ¢ with mouth, clypeus and 
face flavidous. Antennae as long as body, infuscate, rufescent beneath, 
with a broad white band considerably beyond their centre; scape of 
3 flavous below. Thorax immaculate black and closely punctate, 
with strong notauli coalescent in mesonotal disc ; metathoracic carinae 
strong and spiracles circular, but costulae wanting ; areola continuous 
with petiolar area and extending subdivergently from base to apex. Scu- 
tellum deplanate and punctate. Abdomen clear red with the first segment 
except apically, and anus, black ; basal segment parallel-sided to beyond 
the central prominent spiracles, and thence a little explanate, strongly 
sulcate and bicarinate throughout, with postpetiole acutely margined ; 
second segment coriaceous, discally bicarinate and laterally carinately 
reflexed basally; hypopygium of 9 large, convex and apically rounded ; 

* Stephens records (Ill. M. vii.212) Mesoleptus narrator, Grav., as British, but there are none in 
his collection and it has not been noticed with us since 1835. It consequently lacks confirmation. 
Gravenhorst’s type is Notopygus analis, Holmgr., differing from the following species inits wanting 
areolet, etc.
