BRITISH ICHNEUMONS. 



Head strongly and closely punctate, dull black. Antennae stramineous- 

 banded in both sexes ; flagellum pale, scape red-marked beneath. Thorax 

 strongly and closely punctate, dull black ; metanotum rugosely punctate ; 

 areola semi-oval, broadly emarginate apically, of ^ transverse ; apophyses 

 short and distinct, stronger in c? . Scutellum very strongly convex, black. 

 Abdomen ovate-lanceolate, dorsally depressed, finely and closely punctate; 

 black, with the two basal and more or less of the third segments rufo- 

 testaceoLis, c? sometimes with apices of the remainder narrowly fulvous ; 

 post-petiole coriaceous, with distinct carinae ; gastrocaeli superficial, the 

 intervening space broader than centre of post-petiole. Legs somewhat 

 slender ; black, with all tibiae and tarsi, and half the front and apices 

 of posterior femora, testaceo-flavous ; onychii black. AVings somewhat 

 strongly flavescent, stigma and nervures piceous ; radix and tegulae ni- 

 grescent. Length, 12-14 ri'"''''- 



The variety auxilifer has the abdomen black, with the second, or second 

 and third segments more or less ferrugineous dorsally, and the hind tibiae 

 piceous. 



This species was introduced as British by Marshall, in his 1870 cata- 

 logue ; Kriechbaumer says it " preys on a caterpillar which lives on 

 willows, as I have always taken it, in the end of August or early September, 

 flying round willows or on the flowers near them." I know of no in- 

 digenous records, and on the Continent it is only found in Germany, 

 t ranee and Western Russia.
