Lycorimi.] BRITISH ICHNEUMONS. 141 



and not elongate, of $ somewhat slender ; anterior tibiae of 9 sub- 

 incrassate and basally constricted, the front ones as well as their basal 

 tarsal joint slightly arcuate ; tarsal claws short and distinctly though 

 sparsely pectinate ;' femora apically attenuate. Wings with no areolet ; 

 the inner submarginal nervure somewhat elongate ; ncrvellus antefurcal 

 and intercepting distinctly below the centre. 



This genus resembles in its oblique abdominal impressions none of the 

 other Ichneumonidae but G/vpfa, from which it is easily distinguished by 

 its broader abdomen in proportion to its length, the apically transversely 

 impressed segments and especially by its quadrate scutellum, which bears 

 some resemblance to that of Mctopiiis. It possesses the hitherto un- 

 noticed peculiarity of having the basal abscissa of the radial nervure hardly 

 half the length of the second recurrent in the lower wing. 



Only one species is known.

Distinctly punctate, black and a little shining. Head broadly rounded 

 behind the prominent eyes ; frons anteriorly excavate ; palpi dull strami- 

 neous with their base infuscate ; vertical orbits very narrowly, and the 

 centrally impressed clypeus, flavescent ; face laterally parallel, irregularly 

 and somewhat finely punctate, of 9 immaculate and of $ pale flavous. 

 Antennae with the flagellum ferrugineous beneath. Thorax narrower 

 than the head, somewhat longer than high and sparsely punctulate; pleurae 

 and sternum strongly nitidulous with isolated punctures ; metathorax with 

 five upper areae, of which the areola is nitidulous, strongly carinate and 

 not longer than broad ; basal area wanting, petiolar coriaceous and 

 vertical. Scutellum with an apical mark and the basal carinae flavidous ; 

 postscutellum concolourous. Abdomen with the basal segment some- 

 what short and strongly impressed longitudinally in the centre and trans- 

 versely before the ajjex ; the second to fifth transverse and coarsely punc- 

 tate, with the central triangle smoother; three apical segments of 9 small, 

 nitidulous and retracted ; terebra straight and two-thirds the length of 

 the abdomen. Legs red or fulvescent, with the coxae and base of the 

 trochanters black ; hind tarsi and the apices of their fulvous tibiae nigres- 

 cent, latter basally fiavous. Wings somewhat clouded and normally 

 broad ; radix and tegulae flavescent, stigma piceous ; radial cell lanceo- 

 late, first recurrent intercepted a little below the centre. Length, 6 — 

 H mm. 



Ratzeburg's G. /ins is indicated as svnonvmous \\ith this species by 

 Thomson (O.K. xiii. 1340). 



This species, which is uncunnnon throughout northern and central 

 Europe, was introduced as British by Bridgman (Trans, f^nt. Soc. 1882, 

 p. 162) on the strength of a specimen taken about Plymouth by Bignell, 

 but not mentioned in the latter's Devon catalogue ; later a male was 

 secured by Atmore at King's Lynn, in Norfolk, in May, 1887 — bred 

 (Trans. Norf. Soc. v. p. 66), or captured {/.c. p. 631); and a third speci- 

 men was found by Harwood of Colchester {I.e. p. 66). Ratzeburg records 

 it as preying upon Ti'/ua populella — surely a very small host — in rolled 

 aspen leaves near Neustadt, in July; and says (Ichn. d. Forst. iii. iii )
