- Hind femora rather less stout than in crassipes, with at most their distal 



quarter pale ; at least the proximal two thirds of the fore and mid femora 

 black with a metallic tinge. Antennae with hairs of flagellum standing out 

 rather more strongly, most of them at about 45 . Sculptured part of gastral 

 petiole 1-5 to 2 times as broad as long, its front edge with a less sharp and 

 conspicuous transverse crest . . . splendens Westwood (p. 238) 



6 (4) Sculptured part of gastral petiole 1 -5 to 2 times as broad as long, without hairs 



at the sides. Median area of propodeum nearly always with a transverse 

 costula, or some coarse wrinkles. Antennal sixth funicular segment 1 -6 to 

 1-9 times as long as broad. Large species, 2-8 to 4 mm. 



splendens Westwood (p. 238) 



- Sculptured part of petiole 2-5 to 3 times as broad as long, often with one to 



three hairs on each side. Median area of propodeum without a transverse 

 costula, without coarse wrinkles, though sometimes with fine oblique car- 

 inulae. Either the sixth funicular segment is at most 1-5 times as long as 

 broad ; or size is at most 2-6 mm. ....... 7 



7 (6) Both mandibles with four teeth. Combined length of pedicellus and flagellum 



1 -3 to 1 -4 times breadth of head ; sixth funicular segment 1 -3 to 1 -5 times as 



long as broad ...... brevicornis Thomson (p. 240) 



- Left mandible with three teeth, right mandible with four. Combined length 



of pedicellus and flagellum about 1 -5 times breadth of head ; sixth funicular 

 segment 1-4 to i-8 times as long as broad . simillimus Delucchi (p. 241)

Type material. Ichneumon nigricornis Fabricius. Three specimens stand under 

 this name in the private collection of Fabricius in Kiel, and one in the Lund collection 

 in Copenhagen. The original description contains the words " Habitat Hafniae 

 Dom. Lund ", and the specimen in the Lund collection agrees with the description 

 and is designated LECTOTYPE. The specimens in Kiel are Torymus (one which 

 I have examined critically being a female of the overwintering form of T. auratus 

 Fourcroy) and do not agree with the description. The name Ichneumon nigricornis 

 Fabricius is twice pre-occupied, by /. nigricornis Retzius (1783, Gen. Sp. Ins. : 70) 

 and /. nigricornis Gmelin (1790, Linn. Syst. Nat., ed. 13, 1 (5) : 2719), and therefore 

 falls into synonymy. The lectotype of nigricornis Fabricius bears three labels, 

 (1) an original label of the Lund-Sehested collection, " D. nigricornis ", (2) a red 

 label " TYPE ", (3) one reading " Lamprotatus nigricornis (F.) det. K.-J. Hedqvist 

 1962.".
