BRITISH ICHNEUMONS. I45' 



hind pair apically black ; tarsi red, the hind ones fuscous towards the 

 extremity. Wings slightly clouded ; stigma red, tegulae piceous. Length, 

 IO-I2 mm. 



The (J with its abdomen broad, one, two, or three white anal marks, 

 face and clypeus almost entirely flavous-white, the llagellum red beneatii, 

 the thyridii broader than the intervening space, will be at once recognized. 



Found in June, near London ; very rare (Stephens). It is recorded 

 only from the Pyrenees and Germany, where Gravenhorst took it on 

 flowers of Pastinacea sativa.

Head slightly narrowed behind eyes, cheeks almost smooth beneath ; ? 

 black, with frontal orbits narrowly white or more rarely rufescent ; $ palpi 

 and mandibles pale, sides of clypeus, of face broadly and sometimes a genal 

 mark, flavous. Antennae of ? setaceous, somewhat compressed centrally, 

 and sub-dilated before the apex, black with white band on joints nine 

 to fifteen, or tricoloured ; first joint less than thrice longer than broad, 

 ninth quadrate ; S black with scape flavous, and flagellum rosy, beneath. 

 Thorax black, without pale callosity at radix ; metathorax with complete 

 upper areae, of which the areola is quadrate, rarely transverse. Scutellum 

 hardly convex, more or less white ; of $ flavous. Abdomen black ; o 

 strongly explanate centrally, with segments two and three, and often basal 

 angles of four, red, five to seven broadly, and fourth often minutely, 

 white-marked ; of S lanceolate, with segments two and three only flavous, 

 sometimes marked with red or black, its apex immaculate ; post-petiole 

 aciculate ; gastrocaeli large, somewhat deep and rugose. Legs red in $ , 

 flavous in ^ ; coxae, all the femora partly, and hind tibiae totally at apex, 

 black ; hind tarsi entirely fuscous. Wings somewhat clouded ; stigma 

 red, tegulae black. Length, 10-12 mm. 



The ? may be known by the broad white-yellow antennal band ; 

 the post-annellus not longer than scape ; stoutish mandibles ; somewhat 

 coarctate thorax, whose areola is sub-transverse ; abdomen and its deep 

 thyridii broad ; terebra scarcely reaching beyond the anus ; segments five 

 to seven with broad, four sometimes with small, whitish mark ; legs some- 

 what stout ; scutellum flavescent-white. 



From the ? of /. i^raci/icornis, which it resembles in its gastrocaeli and 

 thyridii, it is distinguished by the flagellum being sub-dilated before its 

 apex and the joints shorter beneath ; the terebra shorter ; the femora 

 thicker, black, anterior and intermediate broadly red apically ; the 6 fla- 

 gellum is rufescent beneath, the face and clypeus almost entirely whitish- 

 yellow. (The S described by Thomson in the " Annales " had the 

 flagellum croceous beneath ; the abdomen broad, with the last three or 

 four segments white-marked, and belonged to a different species, probably 

 /. silaceus). 



Bridgman took the male of this species in the neighbourhood of 

 Norwich, and I have seen a female captured by Colonel Ycrbury, at
