BRITISH ICHNEUMONS. 



A Stout species. Head a little narrowed behind the eyes, cheeks and 

 temples moderately broad ; black, the ? with part of the mandibles and 

 of the frontal orbits red ; the 6 with palpi, mandibles and labrum stra- 

 mineous, face entirely or for the most part white. Antennae with first 

 flagellar joint longer than broad ; ? rather stout, attenuate towards apex, 

 black and rather paler beneath, with whitd band on joints seven to fourteen ; 

 S black with the scape white, flagellum rufescent beneath, and joints eleven 

 to nineteen forming a white band. Thorax black, callosities before and 

 beneath the radix in both sexes white; metathorax rugosely punctate, with 

 three upper areae, of which the areola is a little broader than long. Scu- 

 tellum white, shining, and very obsoletely punctate. Abdomen black, 

 segments five to seven, and in ? the fourth, white-marked ; post-petiole 

 aciculate, gastrocaeli somewhat deep, with the intervening space rugose- 

 aciculate. Legs black, somewhat stout : anterior tibiae laterally flavidous ; 

 S with the anterior coxae white -marked ; ? with hind coxae closely 

 punctate, without scopulae. Wings a little clouded, stigma fulvous, tegulae 

 of S often flavous-marked ; areolet receiving recurrent nervure slightly 

 beyond centre, sub-triangular, with the lateral nervures almost coalescing 

 above. Length, 13-16 mm. 



I have followed Berthoumieu in restoring Holmgren's original c{ to the 

 present species ; that described by Thomson is a very different insect : — 

 Antennae without pale band ; all tibiae with a complete white band before 

 the base ; hind metatarsi with the basal half white ; sometimes the apical 

 margin of third abdominal segment, or also the sides of the fourth, stra- 

 mineous ; anus immaculate. 



The $ is very like /. Maklini, Holm., but the joints of the pale 

 antennal band are transverse and shorter below, the femora and tarsi are 

 shorter, there are pale callosities before and below the radix, and the 

 abdomen is apically strongly obtuse. 



Mr. T. R. Billups bred the male of this species, in 1886, from Arctia 

 fuliginosa ; it is now in the Bridgman collection in the Norwich Museum. 

 It has also been bred in Britain by MM. Adkin and Barker from the same 

 host {cf. Meeting Ent. Soc. 2nd April, 1890); an example in Beaumont's 

 collection was taken at Lewisham, in April. Holmgren says it is very 

 rare, in woods, in Sweden ; and it is also found in Holstein.

S . Llead black ; mouth, face and frontal orbits flavous-white. An- 

 tennae black, scape beneath white, third and following joints beneath 

 ferrugineous. Thorax black, callosities before and beneath radix white ; 

 metathorax coarsely rugose ; areola sub-quadrate. Scutellum flavous- 

 white. Abdomen, including anus, black, very finely punctate, shining ; 

 second segment apically ferrugineous, the third with two large red marks ; 

 post-petiole very broad, aciculate ; gastrocaeli normal, intervening space 

 aciculate. Legs black ; front femora pale beneath ; all the tibiae pale 

 flavous, the hind ones apically black or piceous ; tarsi flavous, hind 

 ones piceous ; front coxae flavous-marked. Areolet sub-deltoid ; stigma 

 ye'lowish-brown, tegulae and radix white-marked. Length, 16 mm.
