BRITISH ICHNEUMONS. I29 



Clarkston and Leigh, near Bristol, in August (Charbonnier) ; New Forest 

 (Chawner) ; Falkland, in August, and Pettymr, early in May (Evans) ; 

 Essex (Harwood) ; Tostock, Suffolk, in September {fide Bridgman). On 

 Henicleiim sphondylium flowers, in Henstead Marshes, in July ; and in 

 sods of grass, at Bramford, Suffolk, in March. It is known to hibernate 

 in moss, and occurs in woods and meadows on the Continent, where it is 

 common and generally distributed.

The entirely black abdomen renders this species abundantly distinct. 



? . Head strongly narrowed behind eyes ; frontal orbits sometimes 

 obsoletely reddish. Antennae stout, not compresso-dilated towards apex ; 

 white-handed. Thorax entirely black ; areola rectangular, longer than 

 broad, emarginate posteriorly. Scutellum white. Abdomen broad, black, 

 central segments immaculate and not red-margined ; the three apical 

 segments white-marked ; post-petiole centrally aciculate ; second segment 

 basally sub-aciculate, gastrocaeli of normal size and not transverse. Legs 

 black, anterior femora with white apical dot ; front tibiae laterally flavous ; 

 hind femora for the most part black, their tibiae often also black, but 

 sometimes paler basally; hind coxae without scopulae. Wings a little 

 clouded. Stigma red. 



$ . Clypeus black, or, like the facial orbits, white more or less laterally. 

 Antennae stout ; scape white, flagellum ferrugineous, beneath. Thorax 

 black, humeral marks and occasionally pronotum white ; areola striate, 

 quadrate, apically angulate. Scutellum convex, white. Abdomen black, 

 without blue reflection, not rufescent centrally ; post-petiole finely acicu- 

 late ; second segment also aciculate with disc rugose, its gastrocaeli of 

 normal size ; third sub-quadrate. Legs black, front coxae rarely white- 

 marked ; tibiae internally flavous, hind ones sometimes entirely black. 

 Tegulae piceous, sometimes white-marked. Length, 16-18 mm. 



/. 7ugrocastaiie2is is a variety of this species with the second segment 

 more or less castaneous, the tibiae and tarsi red, apically black. 



It differs from /. coiiiputatorius in the antennae never being compresso- 

 dilated, and in its distinctly punctate scutellum. The generic characters 

 render it distinct from Melanichneinnon^ &c. 



Probably a southern species ; Bridgman took males at Eaton and 

 Earlham, in Norfolk, in July and August ; Parfitt found it on Umbellifcrae, 

 in July, in Devon. On the Continent it ranges from Belgium to Spain 

 and Hungary, and is uncommon in France.
