24 BRITISH ICHNEUMONS. 



sometimes white-marked, hind ones coarsely punctate. Wings only slightly 

 clouded, darker in S ; stigma fulvous ; sides of areolet somewhat con- 

 verging above. Length, 16-24 mm. 



Kriechbaumer says this species is probably as variable in colour as 

 C. siigillaiorws^ from which the $ is distinguished by its larger size, coarser 

 but more diffuse puncturation, especially as regards the mesonotum and 

 posterior coxae, which latter are more shining, and by the colour of the 

 pubescence, which is not pure white, but ashy grey. 



Very rare. Taken in the New Forest and in Scotland, in July (Stephens). 

 It is said to be parasitic on Nociuae, and is only found in N.W. Europe, 

 extending as far east as Hungary.

Very like the preceding, though generally narrower and smaller. Head 

 black ; cheeks and temples deeply and coarsely punctate throughout ; 

 frontal and vertical orbits, $ also with maxillary palpi, angles of clypeus, 

 and sometimes marks on cheeks, white. Antennae dilato-compressed and 

 attenuate ; white-banded in ? . Scutellum white ; areola sub-hexagonal, 

 deeply emarginate apically in $^ which sex has also the pronotum bi- 

 maculate, generally callosities at tegulae and sometimes the post-scutellum, 

 white. Abdomen almost linear, broader in 5 , bluish towards the apex, 

 with distinct ventral fold ; segments one always to three, sometimes to 

 four or five, with white sub-rotund marks ; post-petiole gradually explanate 

 apically, aciculate-punctate, its apical angles generally quadrate, sometimes 

 obtuse ; gastrocaeli large and deep. Legs black ; anterior tibiae internally 

 flavous, hind coxae rarely white-marked and in $ always distinctly scopu- 

 liferous. Wings somewhat clouded ; stigma piceous ; sides of areolet nearly 

 contiguous above in $ . Length, 12-16 mm. 



The shape of the abdominal pale marks is different from that of those 

 of C. cyaiiiventris. 



The (^antennae are rarely white-banded (var. nupfus, Berth.), or with an 

 apical white mark beneath the scape ; the metathorax is also said to be 

 occasionally white-marked. 



Stephens, who confused the following species with it, says the present is 

 very rare in the south of England, but, he believes, more frequent towards 

 the north. It appears to be rare in France, and has been bred in Germany 

 from Liparis vionacha. Bignell has taken it at Ivybridge, near Plymouth, 

 in the middle of May ; Marquand in the Land's End District, and Dale 

 records it from Middemarsh, in Dorset. The female is known to hibernate 

 beneath moss.
