BRITISH ICHNEUMONS. I73 



flavous ; flagellar joints cylindrical ; hypopygium spinate. Length, 14 

 mm. (? . 



This species so exactly bears the facies of C. /lavocinc/us, Desv., as to 

 require no detailed description. Therefrom it may be known by the fol- 

 lowing characters : — Duller and slightly narrower. Head not rounded, 

 with longer pilosity behind the eyes ; mandibles red or flavous ; clypeus 

 flavous ; face entirely, or only its orbits, flavous. Flagellar joints short 

 cylindrical, not sub-dentate. Areola not broader than long, apically 

 strongly emarginate ; costae weaker. Petiolar carinae normal ; thyridii 

 exactly transverse ; second and third ventral segments with a strong, 

 bright flavous fold ; the ultimate strongly spinate apically, with very large 

 valvulae ; second and third dorsal segments immaculate, apical half of 

 seventh flavous. Legs rather shorter ; flavous or fulvous, not stramineous- 

 marked ; base of hind tibiae entirely pale, their apices black. Stigma and 

 tegulae fulvous ; areolet broader. 



Mr. F. W. Sladen has taken two males of this species, one at St. ALir- 

 garet's Bay, on 30th August, 1S98, and one, with which he has very kindly 

 presented me, at Ripple Court, near Dover, on the preceding day ; I have 

 also seen an example taken, by sweeping, on 25th August, 1901, at Church 

 Stretton, in Shropshire, by Mr. Alfred Beaumont.

A very handsome, strongly nitidulous species, with white pubescence. 

 Head black ; of c? with clypeus transversely, and more or less of face, 

 flavous. Antennae black, with no pale band ; of S with flagellum more 

 or less red and scape often flavous beneath, its flagellar joints sub-dentate. 

 Thorax shining, black ; of S with pronotum, a callosity before, and often 

 another beneath, the radix, stramineous ; metathoracic spiracles somewhat 

 short ; areola sub-quadrate ; spines wanting. Scutellum slightly convex ; 

 of c? stramineous, of ? very rarely marked with white. Abdomen brilliant 

 black, with the second and third segments red ; the $ nearly always has 

 the third to sixth stramineous-margined ; seventh immaculate ; post-petiole 

 aciculate, broader in S ; gastrocaeli rather large, deeply impressed ; no 

 ventral segment plicate. Legs black, with the hind femora rarely cas- 

 taneous ; c^ has front coxae marked with, and tibiae and tarsi except apices 

 of the posterior, white. Wings a little clouded, stigma piceous ; tegulae of 

 (? white-dotted. Length, 10-14 •^"'i^- 



Both sexes occasionally have the femora red, or the abdomen entirely 

 black ; the variety vexillarius has the second and third segments black, 

 apically flavous margined. 



In France and central Europe, this is a frequent and most beneficial 

 insect, preying upon the turnip-moth, Agrofis segetuin ; its range extends 

 to Algeria. There are, however, but few records from Britain ; JMarc^uand 

 mentions it from the Land's End district; Buckler and Bignell have bred it 

 from Agrolis exciamationis, the latter in South Devon, on i6th July; and 

 Dale records it from Parley Heath, in Dorset.
