236 BRITISH ICHNEUMONS. {^Erigorgus 



laterally carinatc. Abdomen red with base of first segment, disc of 

 second and anus from base of fifth segment entirely, black. Legs red, 

 with coxae black ; front femora at least above and apices of the inter- 

 mediate rufescent, in $ paler ; anterior tibiae flavous and internally in- 

 fuscate ; hind legs entirely black ; $ with anterior tarsi partly flavous. 

 Wings slightly infumate, with stigma piceous-flavous or rufescent, nervures 

 nigrescent. Length, 16-19 mm. 



Gravenhorst's $ may, I think safely, be considered associated with 

 Thomson's 9 which is certainly the species 1 know as British ; my 9 has 

 the face, mouth and cheeks pale with only two longitudinal black streaks 

 below the scrobes ; one $ is concolorous, a second has the orbits and 

 part of mandibles pale, while another has the orbits alone narrowly pale. 



All these were acquired from the late J. A. Clark's collection, contain- 

 ing no Ichneumonidae other than bred from Lepidoptera, and these have 

 every appearance of being bred in company. I have seen only one other, 

 but Desvignes had three British specimens in 1856, Bignell bred it in 

 Devon from Acroiiycta nunyanihidis, and Capron took a male at Shere in 

 Surrey. It appears to be but indifferently known abroad, and I find it 

 recorded only from Piedmont, Hungary, Sweden ; Brischke in Prussia 

 raised it from pupae of Simyra neiima (Schr. Nat. Danz. 1882, p. 137) ; 

 Giraud in France from Ctcnocampa pithyocampa (Ann. Soc. Fr. 1877, 

 p. 405) ; more recently Mocsary has added Chloantha hyperici ?a\A Bomhyx 

 castrensis, and Szepligeti B. ncuslria, to its hosts. Prof. J. W. Carr has 

 shown me a specimen taken in an allotment garden at West Bridgford, 

 Nottingham.

Head not explanate behind the eyes ; 9 with face and mouth flavous, 

 (^ also with vertical dot concolorous ; face somewhat closely punctate, 

 frons rugosely punctate with a fine longitudinal carina, clypeus centrally 

 acuminate, temples rufescent. Antennae shorter than body, black with 

 J scape flavous beneath. Thorax immaculate black ; mesonotum finely 

 punctate, basally subtrans-strigose ; metathorax with distinct central sul- 

 cus, basally carinate on either side. Scutellum laterally carinate and 

 hardly deplanate. Abdomen slender, red with the second segment disc- 

 ally, anus from fifth, and in ^ the first segment to beyond its centre, 

 black ; terebra half length of basal segment. Legs slender, with hind 

 tarsi hardly explanate, their joints cylindrical ; the anterior rufescent- 

 flavous with coxae nigrescent, ^ with anterior coxae basally and hind 

 ones entirely black ; hind legs piceous-rufescent with coxae and tro- 

 chanters rufescent-piceous, their femora discally and tibiae apically 

 nigrescent. Wings basally flavescent, stigma testaceous ; parallel nerv- 

 ure emitted above centre of brachial cell ; nervellus intercepted immed- 

 iately above its centre. Length, 13-16 mm. 



This species agrees with jE. perspicillator in having antennae distinctly 

 shorter than body, but is at once known by the deep-red temples and its 

 broadly pale hind tibiae. It was described as new by Bridgman but 

 synonymised in 1904 by Krieger, who did not consider A. carinahun, 

 Brisch., distinct.
