BRITISH ICHNEUMONS. I03 



rounded. Scutellum sparsely punctate, black or white ; usually with the 



apical half white in c? . Abdomen of $ elongate-oval, of c? sub-cylindrical ; 

 finely punctate and shining, red ; segment four, except its basal angles, 

 fifth entirely, and sometimes first of c?, black; sixth and seventh dorsally, 

 and sometimes five to six apically in c?, white; post petiole somewhat 

 closely punctate and shining ; gastrocaeli distinct and small, especially 

 in 5 . Legs fulvous, darker in S ; coxae, trochanters, apices of hind 

 tibiae and tarsi, and sometimes the femora in part, black ; hind coxae 

 simply and closely punctate, not scopuliferous. Wings hyaline ; stigma 

 and nervures piceo-fuscous, base of former distinctly paler ; tegulae black, 

 radix flavous ; areolet somewhat narrowed above. Length, 7-9 mm. 



The male may be known by its laterally white clypeus, immaculate 

 fourth segment and small gastrocaeli ; and the female by the entirely 

 fulvous front tibiae, which, in B. bilunulatus^ are internally flavous or 

 stramineous. The vertical dot is sometimes nearly wanting in the female 

 and the scutellum often black, which lend it much the appearance of the 

 /. latrator group of species. 



Bignell has taken it, at Bickleigh, in August and September, and Davies, 

 in Cornwall ; it has been bred from Geomeirae, and (Berthoumieu says) 

 from Hadena aditsta, by Bridgman. Mr. C. J. Wainwright took a female 

 in May, 1899, at West Hide, near Hereford ; and I also have females 

 found at Felden, Herts., by Mr. Piffard, and at Lyndhurst and Matley 

 Bog in the New Forest by Mr. Adams and myself. It frequents the 

 flowers o{ Angelica sylvestris, in August, and the female is said to hibernate 

 among moss. It ranges through N. W. Europe, but does not extend 

 further north than Britain, being unknown in Sweden.
