14 BRITISH ICHNEUMONS. \Cratocryptu<:. 



Wings hardly clouded ; radix testaceous or white, tegulae white or white- 

 marked ; areolet somewhat convergent above. Length, lo mm. 



Tlie male may have the tegulae and cheeks black or white, and the 

 anterior coxae are sometimes pale beneath. Gravenhorst mentions females 

 with a dull red callosity beneath the radix ; with the scape badious 

 beneath ; with the basal segment apically castaneous, together with the 

 seventh dor.sally flavidous, and the terebra slightly shorter. 



It differs from C. stomaticus in the comparatively smooth mesonotum, 

 and from C. anatorius in the broader areolet, longer terebra and shorter, 

 thicker petiole of the female. Brischke says Thomson's description does 

 not agree with that of Taschenberg, but I do not consider the dis- 

 crepancies sufficient to warrant such a conclusion. Kriechbaumer thought 

 the areolet in this species and C. sfemocerus, Thorns., too variable in 

 shape to furnish a reliable specific distinction which, he says, is to be 

 found in the coxal coloration, and further that in the former the frons is 

 more nitidulous and centrally foveate, while in the latter it is more 

 excavate throughout. 



All British records appear to be based upon Stephens' mention of this 

 species as occurring about London in June, and confirmation of it as 

 indigenous was certainly badly needed. This is furnished by the presence 

 of a single c? , kindly given to me by Mr. A. Pi.ffard, who captured it at 

 Felden, in Hertfordshire. On the Continent it is found throughout the 

 northern and central districts, but it does not appear to have yet been 

 bred.

Head black, with frons somewhat dull ; S with facial orbits broadly, and 

 the mouth, stramineous, but with the base and apex of the mandibles and 

 generally a clypeal mark, black. Antennae oi $ with scape beneath, and 

 9 with the central flagellar joints, white. Thorax black ; of 1^ with pro- 

 notum usually white and the mesosternum laterally rugose, its central 

 sulcus in both sexes with a bidentate cristula before the intermediate 

 coxae. Scutellum black. Abdomen also black ; of $ narrower than the 

 thorax, with segments two to six ])arallel-sided, the post-petiole carinate 

 and elongate, the apical margin of the three basal segments sometimes 

 rufescent, of the fourth to the sixth glaucous-white, and of the seventh 

 membraneous ; 9 with the terebra as long as the abdomen. Legs red and 

 not stout ; coxae and trochanters black, the anterior of the ^ white-marked 

 beneath ; hinti tarsi, apices of their tibiae, and of the $ hind femora, black. 

 Wings hardly clouded ; radix and tegulae pale stramineous, latter black 

 in cJ ; areolet convergent above. Length, 10 mm. 



This species is very similar to C. furcator in conformation and distribu- 

 tion, but both sexes have the basal segment less elevated and less arcuate, 

 and the areolet rather larger ; the coxae, trochanters and apex of the hind 

 femora of the female are black, and their tibiae red, with only the apex 

 black ; the face of the male is less profusely pale-marked, its tegulae are 

 always black and, in particular, the sides of its mesosternum are rugose.
