Acanthocryptus.] BRITISH ICHNEUMONS. 55 



Thorax and sciitelhim eiuiicly black. Abdomen black, with segments 

 two, three and sides of the fourth, red. Legs red; trochanters white; 

 anterior coxae white, hind ones, together with their tarsi, apices of their 

 femora and tibiae, black. Wings clouded ; radix and tegulae pale flavous. 

 Length, 5 mm. 



No one appears to liave noticed this 6 since it was first described by 

 Oravenhorst and relegated to P/ivi^adeuon by Wesmael (loc. at.). Bridgman 

 has placed it in his collection under the present genus, and I am quite 

 sure that he is correct. (Iravenhorst's name would have to fall in any 

 case, and it appears advisable to tentatively treat it as the unknown S of 

 Thomson's species {cf. Ichn. Brit. i. p. 265). 



Bridgman has, somewhat boldly, recorded the male from Heigham, near 

 Norwich, in June {cf. Trans. Norf. Soc. v. 613) ; and the female, which is 

 new to Britain, was sent me by Tuck, who captured a single example upon 

 the flowers of Angelica sylvestris, in Finborough Park, in Suffolk, on 26th 

 August, 1900. I also possess three females in Capron's collection, from 

 the neighbourhood of Shere, in Surrey.

Head with clypeus discreted and in $ somewhat convex anteriorly ; 

 black, of $ with clypeus and a dot at the inner orbits red ; of $ with the 

 inner orbits, more or less of the palpi and clypeus, with nearly the whole 

 face, white. Antennae black ; of $ sub-setaceous with the scape white 

 beneath, of $ filiform with joints two to four and the apex red, and nine 

 to eleven white. Thorax of ? red, with the pronotum, a pectoral mark, 

 the radical and scutellar regions, black ; of $ black, with a white callosity 

 beneath the radix ; metathorax rugose with complete areae, areola 

 hexagonal, petiolar area excavate and very divergently discreted; spiracles 

 circular, apophyses very strong and acute ; mesosternal sulcus rugulose. 

 Scutellum with basal fovea distinctly transcarinate ; of $ red, of $ as well 

 as the post-scutellum white. Abdomen somewhat narrower than the 

 thorax, black ; of $ elongate, with segments two, three, apex of first and 

 whole or the base of the fourth, testaceous ; of $ ovate, sub-deplanate, 

 entirely glabrous, with the two or three basal segments pale red, and the 

 sixth and seventii a[)ically white ; petiole explanate, post-petiole of ? a 

 little transverse, parallel-sided, carinate throughout and glabrous, of c^ 

 sparsely punctate ; terebra black, half length of the abdomen. Legs 

 black ; the anterior tarsi and tibiae and apices of the front femora ferru- 

 gineous ; hind tibiae and in $ their femora also ferrugineous basally ; 9 

 with hind coxae and trochanters rufescent above ; c^ with the front tro- 

 chanters sometimes white. Wings normal, slightly clouded ; radix and 

 tegulae white, latter in 9 ferrugineous. Length, 7-9 mm. 



The nearly entirely red thorax and rugulose mesosternal sulcus of the 9 , 

 and stout metathoracic a[)()i)hyses of the c?, will at once distinguish this 

 species from all but that ne.xt described.
