194 BRITISH ICHNEUMONS. 



pentagonal, narrowed above ; tegulae and radix of (? often pale. Length, 

 1 1- 1 5 mm. 



This is probably a somewhat common species in Britain, though I have 

 not personally met with it ; it occurs on umbelliferous flowers, in August 

 and September ; Gravenhorst also found it in May, probably after hiber- 

 nation, on the Continent, where it is widely distributed and has been bred 

 from Cuculiia verlmsci, C. argentea and C. ariemisiae, and from Anuria 

 niyrtillii. It is recorded from Darenth Wood, the New Forest and Horra- 

 bridge, in Devon, from June to August, as well as from Essex; I have 

 seen females taken by Bradley, at Barmouth and Wyre Forest, early in 

 September ; and \Vainwright has kindly given me an example captured in 

 the middle of September, at the latter locality ; Dale records it from the 

 Isle of Purbeck, in 1836.

Head narrowed towards the mouth and behind the eyes, black ; clypeus 

 finely rugose ; mandibles bidentate, piceous or ferrugineous ; the $ has 

 the frontal orbits and part of mandibles and palpi flavous. Antennae 

 setaceous, flavous ; black towards their apices and sometimes fulvous be- 

 neath ; of $ not white-banded. Thorax black, of $ with lines before and 

 beneath radix flavous ; areola transverse, costulae and apophyses wanting, 

 Scutellum flavous. Abdomen black with the second and third segments 

 more or less red centrally or laterally, the fifth to seventh white-margined ; 

 the second of $ with two lateral flavous patches ; post-petiole aciculate ; 

 gastrocaeli small and not very deep ; second and third ventral segments 

 only plicate ; the ultimate in $ elongately acuminate. Legs normal, 

 fulvo-flavous, wdth the coxae, trochanters and apices of hind tibiae, tarsi, 

 and sometimes of femora, black. Wings a little clouded, stigma red ; 

 areolet pentagonal, somewhat narrowed above. Length, 12 mm. 



An abundantly distinct and handsome species, at once known by the 

 bright basal ten flagellar joints and abdominal markings. 



This species ranges, on the Continent, from France, through Germany 

 and Belgium, to Sweden, and is probably rare in Britain ; Stephens 

 took it, at Coombe Wood and Richmond Park, in June ; he figures his 

 /. diinidiatus (J.c. pi. xxxix. 7%". inf. dext.), which was captured in the north 

 of England ; the males are found upon umbels and the females are abroad 

 till the end of September; Wesmael (1854) bred it from a Noctuid pupa 

 in May.
