250 BRITISH ICHNEUMONS. | Euryproctus 


The facial colouration, smoother metathorax, more parallel-sided 
areola, flavescent tibiae and distinct areolet render it distinct from &. 
notatus, its lack of costulae from Z. mznufus and the position of the ner- 
vellus from £. /ateralis. The form MZ. rufocinctus differs, says Pfan- 
kuch, in having the abdomen black with only the third segment discally 
pale castaneous. 
It is said to occur in July and August at Breslau, in Silesia, and to have 
been taken by Hope about Netley (Grav.); very rare in Sweden during 
July (Holmgr.). Itis nearly certain that Stephens’ records of this species 
(/.c. 229 ef 254) from London, Norfolk and the New Forest are incorrect, 
since it is not represented in his collection, and the only example known 
to me as British isa 9 in Desvignes’ collection in Mus. Brit., upon the 
strength of which (and two others erroneously placed with it) Marshall 
retained it in 1872 under both the genera J/esoleptus and Tryphon.

Head not posteriorly constricted, with mouth and more or less of cly- 
peus alone flavescent ; mandibular teeth nigrescent and of equal length ; 
cheeks elongate. Antennae filiform, hardly shorter than body, infuscate 
or ferrugineous and darker above. Thorax immaculate black; metano- 
tum scabrous with areola small and triangular; petiolar area entire and 
crescentic. Abdomen subpetiolate, as broad as head and thorax, oblong- 
ovate ; black with znd and 3rd segments red, almost always more or less 
broadly binotated or transfasciated with black; the 4th often more or 
less red-marked and the 5th to 7th always apically flavidous ; basal seg- 
ment with distinct spiracles a little before its centre, its base not very 
slender, gradually dilated apically and only twice longer than apically 
broad, centrally distinctly sulcate and bicarinate to beyond its centre ; 
ventral plica flavous; terebra black and very shortly exserted. Legs 
normal, red; coxae and trochanters black, with anterior usually fer- 
rugineous beneath ; hind tarsi rarely infuscate. Wings subhyaline, stigma 
and radius infuscate, radix and tegulae pale stramineous; areolet want- 
ing; radius apically straight; nervellus distinctly antefurcal and inter- 
cepted considerably below its centre. Length, 5—7 mm. 
This is by no means easy to recognise, as is indicated under the next 
species, and I was mainly able to do so by an examination of Desvignes'’ 
examples in Mus. Brit., where also are those taken not uncommonly about 
London in July by Stephens ; but Hope’s female from Netley in Shrop- 
shire is probably at Oxford and was named by Gravenhorst, who tells us 
that it occurs on umbelliferous flowers in July and August in Hungary, 
Austria and Germany, whence its range extends over most of Europe. I 
find no subsequent British records, but the species is quite one of our 
commonest and I possess it from Tostock during June and September, 
1900 (Tuck) ; near Plymouth (Bignell) ; Kingsdown near Dover in July, 
1898 (Sladen); Botusfleming, Bishops Teignton, Lastingham in Yorks
