2o6 BRITISH ICHNEUMONS. 



last in having tlie hind coxae marked, and segments one to six narrowly 

 margined, with flavous ; flavolinibatus has the femora apically, tibiae later- 

 ally and the margin of segments two and three flavous, with the fourth 

 glaucoLis-whitc margined ; (]uadriciiv::^ulati(s has the anterior femora and 

 tibiae, and the hind tibiae basally and internally, red, with the third seg- 

 ment at its apical angles, and the fourth to seventh margined with, white ; 

 praedaior has segments three to five red-margined, and the seventh only 

 white-marked ; pratensis the tibiae and tarsi fulvous, the hind ones being 

 apically black, with the coxae sometimes partly white, and segments two 

 to four narrowly margined apically throughout or laterally with flavous — 

 this, Stephens says, is rare about London, in July. The remaining seven 

 specifically described varieties have the anus immaculate. Ichneumon Goe- 

 darti^ has the scutellum white and the apical segments immaculate — taken 

 near London and in Norfolk, says Stephens ; in fttniigafor the body is 

 stout, the scutellum black and the wings often strongly clouded— this has 

 been taken at Darenth Wood, Stephens says, and in the New Forest ; the 

 var. stygius, Berth., differs from fumigator in having the central segments 

 unicolorous black ; imp}-essus has scutellum white, fourth segment, as well 

 as second, third and tibiae, fulvous, with the hind coxae often white- 

 marked — this occurs in Hungary ; sibilatis has scutellum white, femora 

 and tibiae mainly red, and the abdomen black with the second segment 

 piceo-flavous — a German form ; from siln/ans, fossorius differs in its white- 

 marked coxae and basal segment ; flavifctnur has the scutellum and two 

 dots on the clypeus white, with segments two, three, base of four, femora 

 and tibiae, flavous — recorded from France and Austria ; ignoUts has the 

 scutellum entirely or apically white, with the anterior legs entirely red — it 

 is found in Provence. As to the acknowledged varieties, not described as 

 good species, their name is legion : Tischbein, at Stett. Zeit. 1875, p. 274, 

 alone, tabulates forty forms of the male — verb. sap. : cf. loc. cit. I 



This species occurs in June, August and September, on Angelica sylves- 

 iris and other Umbelliferae ; it has been bred from Abrostola iirticae and 

 A. Iriplasia, and the female hibernates. Its continental range is through- 

 out central and southern Europe to northern Africa. In Britain, it is 

 probably a southern species, hardly likely to occur in Scotland, since it is 

 unknown in Sweden ; Stephens says it has been taken near London, and 

 Beaumont has an example from Bury St. Edmunds ; it is also recorded from 

 Essex. Many of the above enumerated varieties, moreover, are unlikely 

 to occur with us at all, probably being due to influences which do not 

 here obtain.

1 Whether Ichneumon cinctorins, Desv. Cat. 25, merits specific rank, or whether it be, as would 

 appear more probable, a mere variety oi A. jntiguttatns, allied to Goedarti, is at present an un- 

 answerable question, and I prefer to tentatively treat it in the latter fashion (cf . E.M.M. igo2, p. 123). 



Head black ; mouth parts, whole of clypeus, sides of face, and frontal orbits narrowly, whitish ; 

 exterior orbits immaculate. Antennae setaceous, black throusjhout, half length of body. Thorax 

 black; metanotum with complete areae, of which the areola is ill-defined and Iiniate. Scutellum 

 flavous. Abdomen narrow, equilateral, deplanate ; dull, more shinini;: towards the aniis ; entirely 

 Ijlack or with apex of second segment laterally and apical h df, as well as whole lateral margin, of 

 third, castaneous ; post-petiole aciculate, gastrocaeli small; ventral fold on segments two and three 

 sometimes indistinctly extending to fifth. Legs black ; base of femora narrowly, of tibiae broadly, 

 and of the tarsal joints, fulvous. Wings hyaline, base not darker; nervures piceous ; stigma stra- 

 mineous. Length, 15 mm. 



There are two examples in the British Museum ; one from Desvignes', and one from Stephens', 

 collection, which latter is said to have been taken in Hants., before 1835.
