Perispudus] BRITISH ICHNEUMONS. 233 

Thorax immaculate, with superficial notauli; mesopleurae closely punc- 
tate, speculum glittering ; discal metanotal areae indistinct; petiolar area 
short and entire. Abdomen oblong, immaculate black; basal segment 
stout, elongate, gradually dilated towards its apex, obsoletely margined 
laterally, with prominent spiracles a little before the centre; terebra not 
short. Legs somewhat slender, elongate and red ; coxae and trochanters 
black, with front ones rarely flavous beneath; anterior tibiae internally 
flavidous and the hind ones with at least their apical half, and whole 
tarsi, black ; anterior tarsi whitish. Wings normal, slightly clouded, with 
stigma dull testaceous, radix and tegulae nigrescent; areolet obsolete or 
very small, apically incomplete, irregularly triangular and_ elongately 
petiolate ; basal nervure oblique ; nervellus elongately postfurcal, inter- 
cepted far above centre. Length, 11—134 mm. 
Thomson says the antennae are pale-banded in both sexes; my ? 9 
lack all trace of annulation, but Rev. F. D. Morice took a @ with sucha 
band at Sunningdale in Berks on 6th June, 1903. 
A male from Genoa (Grav.), central and southern Sweden (Thoms.), 
Germany (Kriech.), Belgium (Tosquinet) and France (Gaulle). It was 
introduced by Dr. Capron (Entom. 1884, p. 46) as British on the strength 
of a male he took at Shere in Surrey during that year ; this, with a smaller 
one, is in his collection. Marshall noted, in MS., that it was “‘ Taken at 
Ivybridge repeatedly by Bignell and by me at Botusfleming ” in Corn- 
wall; there isa male from the latter locality in his collection; Bignell 
took it at the former on 31st May, and Stenton found a male at Wimble- 
don on 3rd June, 1910. It appears to be confined to the south of the 
Thames, and neither Bridgman nor I have seen it in East Anglia. 
Besides Capron’s males I only possess the same sex, undoubtedly much 
the commoner, from Wimbledon where Sich took two flying over honey- 
suckle on 25th May, rgo1; St. Ervan in Cornwall where Davies found it 
in June, 1904; and several of both sexes from St. Andrew and Guernsey, 
captured by Luff towards the end of July, 1908. 
CATOGLYPTUS, Holmgren. 
Holmgr. Sv. Ak. Handl. 1855, p. 106. 
Head transverse and not buccate with vertex a little emarginate; cly- 
peus subelevated and laterally foveate; lower mandibular tooth always 
decidedly the longer; eyes entire. Antennae filiform and apically atten- 
uate; flagellum with 45—50 joints; scape ovate. Notauli generally 
distinct; metanotal areae more or less entire; spiracles circular. Scutel- 
lum subconvex. Basal segment somewhat curved, petiolate with post- 
petiole explanate; pygidium in both sexes entire; terebra shortly exserted 
and distinctly reflexed. Legs slender with femoral apices nearly always 
attenuate, hind femora occasionally incrassate; tarsal claws simple. 
Wings with very rarely a trace of areolet. 
This genus is allied to Holmgren’s Luryprocfus and Nofopygus in the 
curved basal segment, with distinctly slender petiole and gradually ex- 
planate postpetiole, but differs from the former in its unequal teeth and 
curved terebra, from the latter in the ventral emission of the terebra and: 
unemarginate apical segments. In 1883, Thomson divided this genus 
into four sections founded on the capital excavation and these he erected
