130 BRITISH ICHNEUMONS. \HemiteIes. 



somewhat slender and filiform, with the pedicellus conspicuously white 

 and the second flagellar joint hardly one-fourth shorter than the first ; of 

 $ slightly longer than the body, with the basal joints or only the scape 

 stramineous beneath, of $ dark ferrugineous with the scape paler beneath. 

 Thorax shining, black, sometimes dull reddish in the $ ; notauli distinct 

 and extending to the centre ; metathorax sub-glabrous with white lateral 

 pubescence, costae distinct and areae complete ; areola entire and 

 hexagonal or sub-quadrate, broadest basally ; apophyses obsolete. Abdo- 

 men glabrous and nitidulous, oblong-ovate, nearly parallel-sided and a 

 little narrower than the thorax, of $ deplanate, of $ convex ; second 

 segment, usually base of the third, and in $ sometimes the sides of the 

 apical ones, red, testaceous or stramineous ; basal linear and only slightly 

 explanate shortly before the apex, nearly four times longer than broad, 

 with inconspicuous spiracles ; post-petiole sub-glabrous with obsolete 

 aciculation ; terebra half the length of the abdomen. Legs slender and 

 entirely testaceous, with only the claws and apical tarsal joint darker. 

 Wings hyaline and somewhat ample ; stigma pale piceous, radix and 

 tegulae bright stramineous ; areolet pentagonal with the outer nervure 

 obsolete and the nervellus not intercepted. Length nearly 3 mm. 



The male is said to be similar in size and conformation to H. imbecilbts. 



The female of this species is very abundant in Britain in spring and 

 autumn ; Beaumont has given it me from Harting in Sussex, in September, 

 Piffard from Felden, Bedwell from Oulton Broad, in October, and Mr. A. 

 C. Bowdler an entirely castaneous specimen from Blackburn. I have 

 captured it in Suffolk at Gorton Cliffs and on Angelica flowers at Claydon 

 bridge, in August, on house-windows at Southwold in September, beneath 

 willow-bark at Ipswich, in November, and pine-bark at Foxhall, in February 

 beaten it from yew-trees in the Bentley Woods, sparingly in March and 

 commonly in April, on the second of which month I have swept it from 

 water-weeds at Ipswich. Tuck has sent it me from Tostock and Fin- 

 borough Park, in September, and Bungay, in October, from the same 

 county. Marshall has found it in Yorkshire, Chitty at Doddington and 

 Huntingfield in Kent, and Bignell at Bickleigh in Devon. I once took a 

 female crawling over the stool of a new-felled pine in the Bexhill High 

 Woods in Sussex, in March ; but it has not been bred here, though on 

 the Continent Kirchner and Brischke record it from Liinacodes asel/us, 

 Penthina cynoshana and, perhaps, Spilonoia ocelhxna. It is most probably 

 hyperparasitic.
