310 BRITISH ICHNEUMONS. | Lrromenus 

the cocoons of Lophyrus pint in Germany. Gravenhorst mentions a 
variety with the hind legs mainly black. 
It is by far the commonest of its genus both here and abroad; de Fons- 
colombe says it occurs about Aix in the spring, that it is frequent in 
September and beginning of October on umbelliferous flowers, especially 
Peucedanum silaiis ; it occurs in Germany in flowers and grassy places in 
July and August, though apparently rare in Sweden and but once bred, 
from Psecadia pusiella. ‘‘ Not very abundant: taken at Darenth wood in 
June, and other places within the metropolitan district’ (Stephens) ; 
Brundall, Eaton and Poringland, in Norfolk (Bridgman) ; fifteen from 
Bugbrooke in Northants, Nunton in Wilts, Cornworthy in Devon and 
Botusfleming in Cornwall (in coll. Marshall) ; a full series from Shere in 
Surrey (Capron coll.) ; on Angelica flowers at Tostock and Finborough 
Park, Suffolk, in September and two at Bungay on 3rd October, 1900 
(Tuck). It has occurred to me in the same county, always on the flowers 
of Foeniculum vulgare, Angelica sylvestris and Heracleum sphondylium during 
the last eleven years at Alderton, Kenton, Fordley, and in my Monks’ 
Soham garden, from 26th August to 29th September only. It is not 
known to hibernate.

Erromenus analis, Brisch. Schr. Nat. Ges. Danz. 1878, p. 101, ¢ ¢; cf. Phys. 
Ges. Konig. 1871, p.95; Thoms. O. E. xii. 1258, ?. 
A black species, with the hind femora concolorous and anus red. Head 
narrower than thorax and not constricted posteriorly; face strongly pro- 
tuberant and centrally closely punctate; mouth and clypeus red, with the 
latter deeply discreted and its lateral foveae not tomentose. Antennae 
short with the flagellum piceous, its second joint almost transverse. 
Thorax somewhat shining, with distinct notauli; metathorax punctate 
with five discal areae, of which the areola is longer than broad and 
parallel-sided. Abdomen black with the anus more or less broadly and 
terebra red or castaneous ; basal segment dull; second to fifth narrowly 
fulvous apically; middle of fifth to apex usually red; venter pale. Legs 
red, with the hind femora and trochanters more or less black; tibiae 
basally pale ; front femora basally black-marked. Wings with tegulae 
and radix flavous, stigma piceous ; areolet triangular, oblique and petio- 
late ; nervellus intercepted below its centre. Length, 34—7 mm. 
This species is narrower, but hardly smaller than £. frenator. It is 
said by its author and Bridgman to resemble the genus “xvochus in the 
conformation of thorax and abdomen; the latter adds (Trans. Ent. Soc. 
1883, p. 169) that the central incisures are not always pale, the hind tibiae 
sometimes have a prebasal dark mark and the posterior tarsi are apically 
piceous. 
Brischke bred it in Prussia from JVemafus larvae feeding on Salix 
viminalis and from a gall of Mematus Valisnier’ ; and Thomson has found 
it in Sweden. Bridgman introduced it as British (/oc. cz/.) on the strength 
of a single male bred by J. E. Fletcher of Worcester from ematus crassu- 
lus. There are two examples in Marshall’s collection from Botus- 
fleming in Cornwall and another, of the minimum size, from Lastingham 
in Yorks. Stenton has met with it in June and July at Herne Hill and 
Wimbledon.
