BRITISH ICHNEUMONS. 20I 



in Devonshire, where it is found at Bickleigh and Horrabridge, adding that 

 the males are frequently to be met with on flowers by woodsides, in June 

 and July. I have seen examples from Blackheath, Lewisham, Plymouth, 

 Bodiam, Lynmouth, Dover, Portland, Birmingham, Worksop, Reading, 

 Shotover ; Hayton Moss, in Cumberland ; Edinbugh, Ormiston, Aberlady 

 and Gullane, in Haddington ; and possess others from Eusby and Strath- 

 blane, in Stirling ; King's Cross, in Arran ; Bonhill ; Glengariff, in Cork ; 

 Barnsley, Lastingham and Ravenscar, in Yorks. ; Treswell and South 

 Leverton, in Notts. ; Ashby, in Lines. ; Westhide ; Eelden ; and from 

 Tostock, in Suffolk. In Britain it has been bred from Va/iesssa Atalanta, 

 Saiurnia carpini, Lasiocampa rubi (Buckler), Notodonta camelina early in 

 June ; Agrotis segefnm and A. Ashivorthii, Noctiia xanthographa, Triphaena 

 ofl'ona in July, and T. pronoda. Curiously enough, it never appears to 

 have been found in the early spring, and there appears to be no record of 

 this species passing the winter in the perfect state, though that it does so 

 is, I think, proved by the discovery by Mr. O. E. Janson of a female 

 among dead leaves in his garden, at Highgate, in November, 1901 ; Mr. 

 C. J. Watkins has also found it, at Painswick, Glos., towards the end of 

 October.

Somewhat resembling the last-described species. Head black ; man- 

 dibles bidentate ; internal orbits and, in $, the face except its centre, 

 flavous. Antennae setaceous, flavo-fulvous ; towards the apex, and 

 sometimes above, piceous. Thorax black, callosities before and beneath 

 the radix flavous ; apophyses not large and stout. Scutellum flavous. 

 Abdomen black with second and third segments basally, latter also 

 apically, and remainder usually margined with, flavous ; post-petiole 

 aciculate ; gastrocaeli small, indistinct ; S with fourth ventral segment 

 not plicate, the ultimate apically emarginate. Legs flavous or fulvous ; 

 coxae, trochanters, and hind femora, black. Wings flavescent ; stigma 

 fulvous, tegulae flavous. Length, 14-17 mm. 



The coloration appears to be similar to that of A. armatorius, but the 

 metathoracic spines are much shorter, the fourth ventral segment of the $ 

 is not plicate, and its apical segment is dorsally not entirely pale. 



The $ variety mercatorius has a dot beneath the scape, two on the 

 clypeus and others beneath the coxae flavous. 



This species is found in France and central Europe, extending to 

 Caucasia, in August and September, on flowers of Angelica sylvestris, and 

 other umbels. It has been bred from Agrotis iritici {aquilina, Hiib.) 

 and A. corticae. Stephens says it was scarce near London, in June, and 

 Parfitt adds that he found it widely distributed in Devonshire, on flowers 

 by woodsides, in July.
