l88 BRITISH ICHNEUMONS. 



from Agrolis iucernea, and upon Gnophria rubricolUs and Maviestra 

 (Aplecta) tincta, on the Continent. It occurs from the middle of June 

 to September, and I have found it in the greatest profusion upon flowers 

 of Ani^e/ica sylvestris, near Lyndhurst, in the New Poorest, in August ; the 

 females are certainly rarer than the males and fly more freely in the morn- 

 ing than in the afternoon, when they may occasionally be found resting 

 beneath the flowers. It probably occurs freely everywhere and is recorded 

 from Devonport ; Mousehold and Brundall, near Norwich ; Ivybridge, 

 Longbridge and Seaton ; and as one of the most abundant of the whole 

 group in Devonshire. I possess examples from Land's End, Cheddar 

 in Somerset, Hastings, Boxhill, Felden in Herts, Nottingham, South 

 Leverton, Retford, Birmingham, Carlisle; Bonhill, Dundonald in Ayrshire; 

 Parknasilla and Glengariff, in Cork and from Kilmore. Oxford, Queens- 

 ferry, Dunbar, Essex, Isle of Arran, Ely, Kent.

Closely allied to the last-described species. Head black ; of 9 with the 

 internal orbits flavous and cheeks castaneous, of $ with the mouth, face, 

 frontal orbits, and the cheeks, flavous ; mandibles bidentate. Antennae 

 elongate, black with the scape of the ? castaneous, of the $ flavous, be- 

 neath ; flagellum of former centrally pale-banded. Thorax black, of $ with 

 lines before and beneath the radix, laterally on the prothorax and some- 

 times on the mesothorax, flavous ; apophyses small but distinct ; areola 

 sub-quadrate, costulae obsolete. Scutellum, and in $ usually two dots on 

 post-scutellutn, flavous. Abdomen black, of $ apically truncate ; second 

 and third segments of ? with a broad basal flavous band, which is angu- 

 lated and sometimes divided centrally, of $ with two large flavous apical 

 patches ; the following, at least laterally, flavous-margined ; post-petiole 

 aciculate ; gastrocaeli quite distinct though small ; last segment of ^ 

 entirely fulvous. Legs black ; tibiae and tarsi, except the posterior 

 towards their apices, and the $ anterior femora, flavous. Length, 

 16-18 mm. 



This species differs from A. palliatorius, which it very closely resembles, 

 in having the antennae a little longer, the cheeks somewhat more buccate 

 and always pale, the post-petiole broader with stronger carinae, the gastro- 

 caeli larger and a little deeper, and the femora slightly longer. 



I have seen no British specimens which I could with certainty refer to 

 this species, though Rev. A. Thornley has given me a male, froin the New 

 Forest, in August, and I took another, at Broomfield, near Taunton, in 

 July, 1887, which look very like it ; elsewhere we have only old records 

 of captures, by Hope, at Netley, and by Stephens, in Darenth Wood, in 

 June ; " IcJuieumon fasciatorius " is recorded from Jersey, in Ansted's 

 "Channel Islands," 1862, and appears to have been identified by Walker 

 or Desvignes. It occurs in August, in France and Germany, but has not, 

 I think, been bred.
