82 BRITISH ICHNEUMONS \Campoplex 



with apex of postpetiole always, apical half of second and whole of third 

 and fourth segments red ; third segment with no or obsolete lateral black 

 line. I-egs flavidous with the coxae, trochanters, intermediate femora to 

 beyond their centre and the hind ones except apically, black ; apices 

 of both the hind tibiae and tarsi nigrescent ; $ with anterior coxae 

 flavous-marked, and hind tibiae also basally infuscate. Wings with the 

 tegulae piceous, stigma rufescent, areolet high and narrow, usually shortly 

 petiolate, with recurrent nervure emitted slightly beyond its centre. 

 Length, 10-12 mm. 



Besides the peculiar colouration of the postpetiole, this species may be 

 known by the posteriorly narrow head, subcontinuous genal costa, slightly 

 impressed frons, inferiorly strigose propleurae, dull and not strongly punc- 

 tate mesopleurae, but little excavate metathorax with obsolete areae, pale 

 stigma, elongate areolet emitting recurrent beyond centre, the unusually 

 strongly compressed abdomen with its broadly flavous centre and the 

 mainly concolorous legs. 



Not common in north and central Europe (Thoms,) and bred from 

 Seleiiia tetraltinariah^ Y^x'\Qc\)\i?i\\va.QX (O.E. 1089); France (Gaulle), rare 

 in Belgium in July ( Tosq.). Bred in south Devon on 28th March from 

 Taeniocampa popiiUii by Bignell (Entom. 1885, p. 20); Norwich (Bridg.). 

 I have seen no member of this genus with the postpetiole pale, and the 

 specimens here placed owe their position solely to the centrally fiavous 

 body and stramineous hind tibiae : two males have been given me by 

 Pififard from Felden in Herts and a female by Bankes, who bred it on 

 27th June, 1904, out oi Macaria liiurata from Delamere Forest.

A black species, with centre of abdomen and part of legs rufescent. 

 Head hardly at all constricted posteriorly, closely punctate and densely 

 argenteO'pubescent ; frons not impressed, scrobes simple ; mandibles 

 unicolorous ferrugineous throughout, and basally white pubescent ; palpi 

 dark testaceous. Antennae immaculate. Thorax distinctly and closely 

 punctate ; basal metanotal areae not wanting ; pleurae less closely punc- 

 tate than mesonotum, propleurae sinuately and obliquely striate centrally 

 and below, central impression of mesopleurae closely and regularly striate 

 apically. Abdomen black, with the third to fourth or fifth segments 

 bright red ; terebra exscrted. Legs black with the front tarsi, tibiae and 

 apices of their femora testaceous ; calcaria concolorous. Wings hyaline, 

 with the stigma infuscate and the nervures black ; areolet triangular and 

 shortly petiolate, emitting recurrent nervure before its centre ; nervellus 

 geniculate below its centre ; ba.sal abscissa of radius hardly half as long 

 again as recurrent nervure. Length, 9-12 mm. 



It is a slender species with the abdomen strongly compressed, the 

 pleurae not very coarsely punctate and somewhat shining, the vertex 

 broad, genal costa continuous and the cheeks subbuccate. 



One of the most widely distributed of the genus, extending to India 

 whence I have seen it from Darjiling in October, Mussoorie in June,
