Cry/>/us.] BRITISH ICHNEUMONS. 315 



bisinuate in 9 and curved in ^ ; apophyses slender and sub-acute, 

 spiracles oval-circular. Scutellum black. Abdomen red, with the laterally 

 curved first segment basally or entirely, and the anus, nigrescent ; of S 

 gradually dilated to the fifth segment, with the post-petiole narrow and 

 only slightly broader than the base of petiole, smooth, with spiracles pro- 

 minent and apical angles obtuse ; terebra only slightly shorter than 

 abdomen. Legs red ; coxae, trochanters, hind tibiae, their tarsi and, in ^ , 

 their femora above, nigrescent ; ^ with front coxae and trochanters dotted 

 with, and third and fourth joints of hind tarsi, white ; front tibiae stout. 

 Wings clouded ; radix and tegulae dark, latter rarely white ; areolet not 

 large, obviously convergent above ; nervelet distinct, nervellus intercepted 

 far below the centre. Length, 6 mm. 



Gravenhorst says that the size and outline of the female resemble those 

 of C. sponsor, but that the antennae are rather more slender, and the 

 areolet is apically narrow. The male is distinctly more slender than the 

 female with the antennae thinner. His variety with darker legs is probably 

 referable to C. matre//us, Tschek. 



This species, which Stephens says used to be not very common about 

 London and in Shropshire at the end of June, was sent by Hope to 

 Gravenhorst from Netley ; Parfitt beat it from trees in Devon in July ; and 

 I possess specimens recendy taken by Capron about Shere ; Saunders at 

 (ireenings ; Miss Alderson at Worksop in June ; and Yerbury at Much 

 Markle in Hereford, in May. It occurs throughout northern and central 

 Europe, and Ratzeburg has bred it in Germany from Hylotmpes bajulus.

 broadly, white. Antennae nearly filiform ; centrally white above in $ . 

 Thorax with pronotum dotted or margined with, and a line below radix, 

 white ; metanotum very coarsely rugose, with transverse costae sub- 

 obsolete ; apophyses acute, spiracles oval. Scutellum apically white. 

 Abdomen finely alutaceous, of (^ linear and of ? oblong-ovate, red, with

 laterally curved, dorsally smooth and shining, with prominent spiracles ; 

 post-petiole bicarinatc, of c^ gradually dilated towards apex and not narrow,

 Legs red, with coxae and trochanters black ; hind tarsi infuscate or in S 

 white-banded ; S with hind femora and apex of hind tibiae black ; front 

 tibiae stout and hind ones of 9 distinctly spinulose. AVings clouded ;

This species is similar to C. minatot\ but it has the frons more broadly 

 excavate and sub-rugose, the scutellum and tegulae white -marked, the
