244 BRITISH ICHNEUMONS. [ Euryproctus 

covering base of the somewhat exserted, straight, red, and apically very 
obtuse terebra. Legs red, with all the trochanters and anterior coxae 
flavous; all the onychii, with apices of the hind tibiae and femora con- 
spicuously, and usually extreme base of hind coxae, black. Wings 
hyaline and not large; stigma piceous, basally paler; radix and tegulae 
stramineous; areolet entire, triangular and petiolate; nervellus postfurcal 
and intercepted distinctly a little above its centre. Length, 1o mm. 
Unmistakable in its clear red antennae, abdomen and legs with the 
apices of the hind femora and tibiae conspicuously and determinately 
black. ‘The areolet is often minute. 
This species is recorded from Germany, Sweden, Belgium and Prussia; 
Cameron says it preys on Se/andria Six? and Gaulle tells us it has been 
bred from Selandria serva in France. Hope first sent both sexes to Graven- 
horst from Netley in Shropshire, as recorded in 1829; Stephens found it 
about London in june and July, and there are three from his collection 
in Mus. Brit., with one named by Grav. ex coll. Linn. Soc. Lond. With 
us I believe it to bea common species only in the most marshy localities; 
I have always regarded it as common from an early intimate acquaintance, 
when I first studied the Ichneumonidae in 1898, for it occurred to me com- 
monly throughout the August of that year at Oulton Broad in Suffolk, where 
Bedwell has subsequently found it, from sth July to September. Else- 
where it would seem scarce; Heigham and Brundall in Norfolk, in July 
and August (Bridgman); Lastingham, in Yorks (Marshall); I possess it 
from Bickleigh 23rd September, 1887 (Bignell); Guestling in Sussex in 
1880 (Bloomfield); Lyndhurst in New Forest, zoth September (Adams); 
and Possil Marsh, near Glasgow in August, 1899 (Dalglish).
