232 BRITISH ICHNEUMONS. [ Perispudus 

angular, with its outer nervure pellucid below ; fenestrae confluent; lower 
wings with first abscissa of radius half as long again as recurrent nervure ; 
nervellus intercepted above centre. Length, 9s—13 mm. 
Thomson places this species in his subgenus Perispudus of Mesoletus. 1 
have a ¢@ with the face only flavous longitudinally in the centre. 
It seems improbable both from his description and figure that Bridg- 
man’s female is more than a variety of P. sulphuratus ; he says (loc. ctt.) 
that it differs in having the head narrower posteriorly, the notauli deeper, 
the basal segment much shorter and slightly broader with the following 
much shorter, the antennae black and tarsi paler. Bignell tells us in 
1898 that the single @ described was captured at Bickleigh near 
Plymouth on 11th August, 1880, and another, twelve years later, in Scot- 
land. It is thus described :—Head reticulate, immaculate, narrow behind 
eyes ; antennae as long as body, entirely black. ‘Thorax immaculate, dis- 
tinctly punctate with reticulate interstices ; notauli distinct ; metathorax 
rugose with no areae. Abdomen black with the subquadrate second and 
subtransverse third, with extreme apex of the reticulate and very sparsely 
punctate first segment, whose spiracles are just behind centre, red. Legs 
clear flavous with coxae, trochanters, base of anterior and whole of hind 
femora, and apical third of hind tibiae, black. Wings fulvescent; tegulae 
black, stigma pale testaceous, nervures fulvous; areolet small, petiolate, 
emitting recurrent nervure beyond centre; nervellus intercepted above 
centre. Length, 12 mm. 
Both sexes were recorded from Germany in the middle of July by 
Gravenhorst; Fonscolombe found the male about Aix in France; and 
Thomson records it from Sweden. It is probably local and restricted to 
very marshy situations. Hope sent a single pair to Grav. from Netley in 
Shropshire; Stephens considered it “rare: taken near London, in 
June”; there is one from Govilon in Monmouth in Marshall’s collection; 
Bridgman found it at Brundall in August; Beaumont at Whitby on 14th 
August, 1897; and Morice at Horsell in Surrey on 7th Sept., 1903. My 
dozen examples are mainly from Barnby and Oulton Broads, and Tud- 
denham Fen, in Suffolk, where it is not rare, usually swept from marsh 
grasses and /uncus, though occasionally on the flowers of Angelzca, from 
5th July to 8th September, when it was swept by Bedwell. All these are 
males and another turned up in Lyndhurst in the New Forest in 1gor; 
my only females were captured at Wimbledon Common in August, 1910, 
by Stenton, Lynton in Devon in 1890 by Stanley Edwards, and at the 
Mound in Sutherland on 16th August, 1900, by Col. Yerbury.

An elongate, stout black species, shining and obsoletely pubescent.
