48 BRITISH ICHNEUMONS. [ Exochus 

immaculate; cheeks very short. Antennal flagellum ferrugineous, nearly 
entirely black above. ‘Thorax immaculate, with the areola somewhat 
broad and the costulae strong or obsolete. Scutellum black. Abdomen 
with the basal segment deplanate and its carinae extending beyond the 
centre; the second transverse. Legs red with the coxae and trochanters 
black; hind tibiae nigrescent with a white band near their base, their 
tarsi white with the joints becoming gradually more determinately black 
apically. Wings somewhat infumate with the stigma infuscate-testaceous 
and tegulae dark-marked. Length, 6 mm. 
Known by the short calcaria, immaculate frontal orbits and scutellum, 
and the black-and-white hind tibiae and tarsi. 
Bignell bred this species in Devon on 4th May froma black larva of 
some TZoririx (probably Z. xylosteana) feeding on honeysuckle (Entom. 
1881, p. 141). I have two females bred by Dr. R. T. Cassal from pupae 
of the Tortricid Penthina dimidiana, found feeding on JZyrica gale at 
Midge Hall, near Doncaster, in rgo1; in both cases the host chrysalis 
was cut irregularly and entirely away from its capital extremity to below 
the face, showing the parasite to have lain in the pupa exactly as had its 
host.

A black species with the scutellum apically pale, the legs red with both 
hind tarsi and tibiae white-banded. Length, 6—7 mm. 
Similar in size, conformation and the pale-banded legs to &. alpinus, 
but with the flagellum infuscate and a little longer, the hind tibiae 
ferrugineous or testaceous with their apices more broadly and the extreme 
base nigrescent, a white callosity before the concolorous tegulae, the 
postscutellum and apex of scutellum flavidous, and the coxae usually 
ferrugineous. 
Var. Woldstedfiz, the black bands of hind tarsi obsolete. 
Var. annulitarsts, carinae of basal segment not extending beyond 
centre. 
The late Mr. Alfred Beaumont has given me three specimens, taken in 
company, at Taynuilt in Scotland during September, 1894, and referred to 
the present species by Marshall, of which two are typically £. no/a/us and 
the third obviously referable to ‘Thomson’s #. annulitarsis and this I 
consequently regard as a variety of Holmgren’s species, than which it is 
said by its author to be more slender with the hind coxae and tibiae black, 
the latter centrally broadly white, and the scrobes longer and deeper 
above the antennae. ‘The typical form does not appear to have been 
noticed in Britain before, but a male of 2. Woldsfedfit is recorded by 
Bridgman (Trans. Ent. Soc. 1887, p. 375) from Earlham near Norwich, 
where he took it in June, 1886,
