BRITISH ICHNEUMONS. 3I 



narrowed behind the eyes ; the areolet is strongly narrowed above, the 

 sides there nearly coalescing ; the coxae of the ? bear no scopulae ; the 

 scutellum is entirely black. 



Found near London and in Shropshire, in June (Stephens). It has been 

 bred, on 14th June, from Byrophila glandifera, in S. Devon ; and from 

 Notodonta dodonea. It is a common parasite upon Abraxas grossu/aria 'a, 

 and has been found in Norfolk ; Essex ; South Leverton, in Notts., in 

 June ; Hastings ; Lastingham, in Yorks., and Bickleigh, in Devon.

Head black ; face covered with long white pilosity in $ ; mandibles red 

 in ? \ frontal, a dot at the vertical, and sometimes the external orbits, white ; 

 $ also has angles of clypeus and lines at the facial orbits white, or the head 

 entirely black ; clypeus slightly but distinctly bisinuate apically ; cheeks 

 not buccate. Antennae sub-filiform, a little attenuated ; white-banded in 

 ? , entirely black in $ . Thorax nitidulous, entirely black or with a pale 

 dot before the radix in both sexes; areola transversely sub -hexagonal, 

 apically concave ; costulae entire. Scutellum black, shining, with distinct 

 sparse punctures ; rarely with two white apical dots. Abdomen convex, 

 shining, black, sometimes slightly cyanescent; post-petiole aciculate, laterally 

 punctate ; gastrocaeli large, deep and rufescent with the intervening space, 

 and base of the second segment, irregularly striate. Legs stout, for the 

 most part red ; the coxae and apices of hind tibiae and their tarsi black ; 

 hind coxae closely punctate, not scopuliferous; Wings hyaline, stigma and 

 tegulae piceous ; areolet somewhat broad above. Length, 10-12 mm. 



The male may at once be known from the preceding by its white facial 

 pilosity, and the much less blue reflection of the abdomen ; the red femora 

 are also distinctive. 



In a specimen of the pupa of this species, which I recently examined, 

 the antennae were not laid at full length along the abdomen, as is usually 

 the case, but were carried outwards to the tegulae and thence abru[)tly 

 curved inward in such a manner that their apices approximated above the 

 mesosternum ; the mesonotum was deeply sulcate longitudinally in the 

 centre ; and the head was ferrugineous. 



Bridgman took both sexes in Norfolk, the male at Cromer, in June. 

 Piffiird has several times taken it at Felden, in Herts. ; Luff has kindly 

 given me both sexes from Guernsey; and I have seen a specimen in BignelTs 

 collection. I\Ir. Stanley Kemp has bred several of both .sexes together from 

 chrysalids oi Bryophila inuralis, Forst. ( = gland if era, Hb.)at Hythe, in Kent, 

 during September, 1901 ; one of these is a remarkably small female of only 

 6^ mm. in length ; the parasite in emerging entirely removes the capital 

 extremity of the pupa in a somewhat jagged manner, having constructed no 

 cocoon whatever of its own and leaving that of its host transparent, with 

 only some whitish debris in the anal extremity; the larvae-skins and silicious 

 cocoons were intact. This is a widely distributed species throughout 

 western Europe, and occurs, probably, not uncommonly with us.
