M,sochonis] BRITISH ICHNEUMONS. 329 



metathorax discally smooth, with complete areae and centre of petiolar 

 area little lonsj[er than its sides. Scutellum wholly or partly red. Abdo- 

 men testaceous with two basal segments, except apex of second, black ; 

 third, and sometinies the following segments, laterally infuscate, anus often 

 infuscate, especially in J; terebra somewhat shorter than the little curved 

 basal segment. I^egs testaceous with anterior coxae and trochanters, and 

 hind tibiae except their nigrescent extremities, flavidous ; tarsal joints 

 apically infuscate; claws pectinate almost to their centre. Wings slightly 

 infumate, with stigma entirely or infcriorly nigrescent ; tegulae whitish. 

 Length, 6-7 mm. 



Common in Sweden in July and August, and there bred from Tinea 

 eronymcl/a; Holland and Belgium in August and September; bred in 

 France from Sitnacffiis Fahriciana. Dr. Chapman has given me this 

 species, bred by him through R/iog'is gasfcra/or from Orgy/a splendida in 

 Spain during August, 1903. A common species in Norfolk and bred at 

 Kings Lynn by Atmore from A'^o/a ciicuUatella (Bridgman); bred in the 

 middle of July from Hvponojneuta evonyvidia through Liniiicria liirysoslicia 

 in Devon (Bignell); a full series from Shere (Capron) ; Bristol (Charbon- 

 nier); Cornworthy in Devon (IMarshall) ; Greenings in Surrey, INIay, 1872 

 (Saunders); bred from Southport Eiipithcda ahsynthiata early in June, 

 1907, through Campoplegid cocoons (Clutten) ; and from apparently the 

 same species of cocoons from E. oblongata on Angelica sylvcsiris at Don- 

 caster in 1901 (Cassal). I have captured it at Ryde in the Isle of Wiglit 

 in mid-August, and by sweeping in Barnby Broad in Suffolk in mid-I\Iay 

 and at the end of August, 1898. 



18. tenuiscapus, TJioms. 

 Mcsoclionif; tciiiiiscafnin, Thorns. Ann. Soc. Ent. France, 1885, p. 341, d" ? . 



A black species with the legs pale, the abdominal petiole nearly linear 

 and (J anal styls subulate. Length, 7 mm. 



This insect is known in the present group by its longer and basally 

 dark testaceous petiole, the pale stigma, the ]:)ronotum with both nieso- 

 notal and pleural marks and the scutellum pale, and tlic less broadly 

 dark-marked hind tibiae. In the case ot almost any other author this 

 description, all vouchsafed us by Thomson, would appear ridiculously 

 inadequate, but he had so skilled a knack of presenting pertim-nt features 

 and adding to them just those points which distinguish it from allied 

 kinds that I have no doubt the above meagre details will suHire to render 

 the i)resent species sufficiently distinct. 



It was described from Sweden and no one has found it elsewhere, 

 except Bridgman, who queries (Trans. Norf. Nat. Soc. 189+, p. 623) his 

 capture of this species in May at Brundall near Norwich.

An infuscate species, with testaceous markings ; the legs stout and 

 white, the hind tibiae apically and stigma broadly black, with base of 

 latter pale testaceous. Head broader than thorax and posteriorly con-
