^20 BRITISH ICHNEUMONS. [Ussomla, 



transverse impression before the glabrous apex ; second segment similarly 

 sculptured and a little broader than long or in ^ quadrate ; the fourth 

 and following subglabrous ; terebra as long as the body. Legs red, with 

 the hind tarsi alone infuscate ; ^ with anterior coxae and trochanters 

 stramineous and the hind coxae often infuscate or black. Wings flaves- 

 cent ; stigma ferrugineous and tegulae flavous, paler in J ; areolet 

 entire ; nervellus intercepting nearly at the lower angle. Length, 

 6^ mm. 



One of our commonest British species of the genus. Bridgman de- 

 scribed it from a female taken by him at Earlham, near Norwich, in 

 August and adds {loc. a'/.) that Dr. Capron had also taken it at Shere. 

 These latter five females are now in my collection, together with a sixth 

 taken by PifFard at Felden in Herts. Tuck has given me another, w hich 

 he captured in Chippenham Fen, in Cambs., on 19th July, 1901, and dur- 

 ing the following August 1 myself met with it several times in IMatley 

 Bog and at Lyndhurst, in the New Forest. Schmiedeknecht describes the 

 male, which is very common with us, from Thuringia. Butler took 

 several females about Dorking in August, 1900 ; and it has occurred to me 

 at Harleston, Bentley Woods, and Marlesford, in Suffolk, towards the end 

 of July on the flowers of Heracleum ; it first appears in May. 



28. varicoxa, Thorns. 



Lissonota varicoxa, Thorns. O.E. viii. 7G8, ? , et xiii. 1425 ; Schm. Zool. Jahr. 

 1900, p. 388 ; Opusc. Ichn. 1325, <? ? . 



Black. Head narrowed behind the eyes ; J with mouth, triangular 

 vertical spots, cheeks and face except two longitudinal black lines, 

 stramineous. Antennae filiform. Thorax black, of ^ with the pronotum 

 and both sexes with humeral marks stramineous ; mesosternal sulcus 

 slender with a basal transverse line. Scutellum and abdomen black ; the 

 latter with the second and third segments narrowly flavescent at the apex ; 

 terebra not shorter than the abdomen. Legs red with the front ones 

 basally stramineous and the hind tarsi, with the apices of their submutic 

 tibiae, black. Wings with the nervellus intercepting below the centre and 

 the radial nervure not apically inflexed. Length, 7 mm. 



Thomson thus shortly describes this species, which he says is similar to 

 his L. carini/rons, though distinguishable by the colour of the legs, the 

 shorter and narrowly flavous-margined second and third segments. 

 Schmiedeknecht adds that the second segment is transverse and the 9 

 face bears two longitudinal red lines. 



It has hitherto been only known from Sweden, on the Continent. Big- 

 nell captured a specimen, so named by Bridgman, at Longbridge, in 

 south Devonshire, on 27th June (Trans. Devon. Assoc. 1898, p. 503). I
