208 BRITISH ICHNEUMONS. [Lissom/a. 



straight, a little longer than the hind coxae, normally elevated, alutaceous, 

 with the postpetiole nearly parallel-sided and longer than broad ; second 

 segment very nearly broader than long, alutaceous and obsoletely im- 

 pressed before its smooth apex ; the remainder transverse and becoming 

 smoother towards the anus ; terebra as long as the body. Legs red with 

 all the trochanters often partly, the hind tibiae and tarsi entirely, infuscate- 

 piceous; hind legs somewhat elongate with their tibiae and fejnora a little 

 stout. Wings subhyaline ; stigma dark stramineous or testaceous, radix 

 pale and tegulae basally infuscate ; areolet petiolate and emitting the 

 recurrent nervure between its centre and apex ; nervellus intercepting 

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



Holmgren says this female is similar to his /.. higiittata, but with the 

 hind legs longer and obviously stouter. The $ has not hitherto been 

 known. 



(J . Head not abruptly narrowed behind the eyes, black ; vertex 

 rounded, obsoletely punctate and not centrally emarginate posteriorly, 

 with a conspicuous flavous dot at both orbits ; frons somewhat convex, 

 dull and impressed above the scrobes ; face dull and distinctly punctate, 

 a line on either side of the prominent epistoma, confluent apically with 

 the orbits broadly, flavous ; clvpeus strongly discreted, convex, nitidulous 

 glabrous and entirely flavous ; mandibles stout and, like the palpi, flavous. 

 Antennae (7 mm. in length) longer than the body, not very slender, fili- 

 form throughout with the joints cylindrical to apex, immaculate with the 

 two or three basal flagellar joints apicallv slightly nodulose and nearly 

 thrice longer than broad. Thorax black and somewhat nitidulous with 

 the pronotum, a small line on the propleurae, a dot before and a small 

 line beneath the radix, a large hamate mark on either side of the meso- 

 notum shortly recurring into the obsolete notauli, flavous ; mesonotum 

 finely and confluently punctate; mesopleurae and sternum strongly nitidu- 

 lous, finely and distinctly punctate with the speculum glabrous ; metathorax 

 finely coriaceous, becoming longitudinally striate before the longitudinally 

 striate and basally strongly costate petiolar area ; areola distinctly and 

 parallelly carinate throughout, spiracles small and circular. Scutellum 

 immaculate, obsoletely punctate and somewhat nitidulous. Abdomen 

 subcylindrical and entirely black with only the ventral plica pale stramin- 

 eous ; basal segment nearly twice longer than broad, finely and longitud- 

 inally scabriculous, somewhat strongly bicarinate from the deeply im- 

 pressed basal fovea to the superficial transverse impression before the 

 centrally raised and nitidulous apical margin ; second and third segments 

 very nearly broader than long, alutaceo-punctate and obsoletely impressed 

 before their centrally raised apices ; remainder becoming smoother to the 

 anus; ventral valvulae not exserted, truncate, black and pilose. Legs not 

 elongate, red with the anterior coxae and trochanters entirely pale stramin-
