Glj'pta.] BRITISH ICHNEUMONS. 147 



tibiae apically infuscate above, and the tarsal claws elongate and not or 



very obsoletely pectinate. Wings normally broad and slightly hyaline 

 with the stigma dull stramineous, radix and tegulae llavous ; radial 

 nervure apically straight ; transverse anal nervure indistinct and intercep- 

 ted far below the centre. Length, 6 — 8 mm. 



This species is said by Gravenhorst to be similar to G. siibcontit/a, but 

 with the antennae and legs a little longer and more slender. Holmgren 

 gives it as very distinct, not only in the colour of the abdomen and legs, 

 but also in its tarsal conformation. Bridgman says the strongly constric- 

 ted head and nude tarsal claws are very distinctive. 



It is said to occur at the beginning of August, and to be rare in Sweden. 

 In Britain it does not seem to be of more frequent occurrence than the 

 last species, though Bridgman has recorded it from Brundall in Norfolk ; 

 and Bignell has bred it, at the end of June, from Tortiix cos/ana in south 

 Devon. I have seen males taken at Plumstead early in July and a 

 female at Harting in Sussex at the end of August, 1899, by Beaumont; 

 and Dr. Capron found both sexes at Shere in Surrey.

Black and somewhat shining. Head posteriorly constricted ; frons 

 anteriorly subexcavate with one small acuminate tooth ; palpi and often 

 apex of the prominent and discreted clypeus testaceous ; face strongly 

 punctate and pilose with the epistoma subglabrous and tuberculiformly 

 convex. Antennae half again longer than the body ; flagellum ferrugin- 

 eous and darker above, a little incrassate ba.sallv; scape black. Thorax 

 gibbulous, black with pale callosity before the radix ; metathoracic areola 

 basally complete with the costulae obsolete ; petiolar area short, sub- 

 vertical and basally carinate. Abdomen linear-cylindrical, a little 

 narrower and twice longer than the thorax, pale red or black ; basal seg- 

 ment except the margin broadly, and usually three sometimes confluent 

 basal marks on the second to fifth, apex and basal marks on sixth and 

 whole of seventh segments, black ; terebra slender and nearly as long as 

 the abdomen. Legs slender and fulvous with the coxae sometimes, in $ 

 generally, infuscate or black ; hind tibiae apically and their tarsi above 

 infuscate, joints of the latter basally pale ; tarsal claws remotely but dis- 

 tinctly jjcctinate. Wings flayescent-hyaline or slightly infumate ; stigma 

 dull, and radix and tegulae clear, stramineous throughout ; transverse 

 anal nervure indistinctly intercepted far below the centre. Length, 

 5—7 mm. 



This species has the facies of G. /nrs, with the frons horned and the 

 antennae a little shorter and stouter ; it is also said to be very like G. 

 monocerus, but the colour of the abdomen and legs, and especially the 

 tarsal conformation, are distinctive ; as also, says Thomson, are the 

 shorter antennae and less distinct thoracic costae. It is extremely like 

 the next species, but the metanotal carinae are weaker and the terebra 

 constantly longer. 



G. fnmticoniis is not infrequent in grassy places on the Continent, but 

 Bridgman in 1889 said that he did not feel at all sure that it had any 

 right to a position in the British list : he had never seen an indigenous
