Acattthocrypius.] BRITISH ICHNEUMONS. 57 



with iis bjsal fovea simple and not tian.scaiinatc. Abdomen black, witli 

 the three basal segments entirely red, and the seventh alone dorsally 

 white ; terebra black and half length of the abdomen. Legs red, usually 

 with the apices of the hind femora and tibiae, and base of the anterior 

 trochanters, b'ack ; hind tarsi infuscate. AV'ings normal, slightly clouded ; 

 radix sub-stramineous, tegulae ferrugineous. Length, 6-7 mm. 



This female was thought no more than a variety of the preceding species 

 by Gravenhorst, but is indicated under the name Cryptus Hopei^ though 

 not described, as a good species in Desvignes' "Catalogue of British Ich- 

 neumonidae in the Collection of the British Museum," 1856, p. 58. It 

 appears to be much mixed with R. fla^itator, from which it has never 

 been adequately discriminated, though differing very materially in the 

 colour of the legs and abdomen, and the sculpture of the scutellar fovea, 

 which bears no trace of the transverse costae, so prominent in the latter 

 species. 



The two original females were captured by Hope, at Netley, in Shrop- 

 shire ; they still exist in the British Musem, but Desvignes' type is 

 smothered with verdigris. Harwood records it from Essex in the Victoria 

 History; Bridgman found it at Lakenham, Norfolk, in September; and I 

 have seen a specimen taken by Hamm, at Shotover, near Oxford. I have 

 only found it in the middle of summer and not, like the last species, in the 

 autumn ; on the flower-tables of Heracleum sphondy/iu»i, in the Bramford 

 marshes, near Ipswich, loth July, 1899; and in a boggy spot at Barton 

 Mills, in Suffolk, iith June, 1900. Both sexes of Tasclien berg's species 

 were bred from Depressaria heracleana.
