Cratocryp/us.] BRITISH ICHNEUMONS. I5 



Kriechbaumer differentiated this species from C. sfernoceriis upon tlie 

 divergence in colour of the coxae and teeulae. 



Bridgman records this species, which is probably not uncommon though 

 overlooked, from Eaton and Earlham, near Norwich, in June ; and llignull 

 found it at Longbridge at the end of June and at liicklcigh early in July. 

 I possess specimens, taken on the flowers of Heracleum sphondyliuiii, in 

 Bentley Woods and the Bramford marshes, near Ipswicli ; and others 

 taken by Adams in the New Forest, by Piffard, at Felden, in Herts., and 

 by Capron, at Shere, in Surrey ; their dates only range from the 6th to 

 17th July. Stanley Edwards has captured the female, at Lynton, in 

 Devon.

Head black, with cheeks buccate ; of $ with the mandibles, palpi and 

 the facial orbits nearly triangularly, white. Antennae with post-annellus a 

 little longer than the scape ; of 9 filiform, with the central joints clear 

 white and the following sometimes ferrugineous beneath. Thorax immacu- 

 late, with the mesonotum shining and not closely punctate; mesosternal 

 median sulcus terminated posteriorly by a sub-angulated transverse line; 

 the costulae emitted before the centre of the areola. Scutellum black. 

 Abdomen of ? oblong-ovate, with the post-petiole sub-carinate, nearly 

 quadrate and gradually explanate apically ; the sixth and seventh segments 

 of the $ with a whitish membrane extending nearly to their centre, the 

 seventh of ^ with its apical margin centrally pale ; fifth of ? usually with 

 the ventral valvula prominent and the terebra slightly arcuate, nearly as 

 long as the abdomen, its spicula red and sheaths black. Legs red ; coxae 

 and trochanters, except the posterior ones of the $ , hind tarsi, the apices 

 of their tibiae and of their femora, infuscate. Wings somewhat clouded, 

 with the radix piceous or stramineous ; tegulae of 9 black, of $ white ; 

 areolet strongly convergent above. Length, 9 mm. 



The more strongly convergent areolet, buccate cheeks, position of the 

 costulae and the coloration of the male's head and of the female's legs will 

 serve to discriminate this species, of which (Iravenhorst mentions female 

 varieties with the front femora externally black and the hind tibiae entirely 

 infuscate. 



There seems to be no room to doubt that Thomson's male of C. anatorius 

 is C. bilineatus, since it agrees in every particular with (Iravenhorst's 

 description, and the central segments are not always basally badious. 

 Taschenberg adds that the metathorax is finely rugulose, with the basal 

 transverse costa wanting, the areola laterally indicated, hexagonal and 

 apically incomj)lete ; the pleural longitudinal costae strong, apophyses 

 distinct, with small and circular spiracles ; the post-petiole is parallel- 

 sided and nearly as long as the laterally curved and sub-explanate petiole ; 

 the two basal segments are finely coriaceous. 



This is probably (juite a common species in Britain. It has been re- 

 corded from Mousehold, near Norwich, in August, Horral)ridge early in 

 October (which points to its hibernating in the perfect state), from MaUlon, 

 in Essex; and by Ste|)hens, who says it used to be not uncommon in June 

 near London and in Shropshire. Bradley has taken it at Sutton, near
