314 BRITISH ICHNEUMONS. | Grypocentrus 

Legs pale testaceous with coxae basally, the hind femora centrally and 
their tarsi, subinfuscate. Stigma infuscate and triangular, areolet pen- 
tagonal, nervellus intercepted below centre. Length, 4 mm. 
Similar to G. cinctellus but with the body more finely punctate, the 
pleurae very shining, the clypeus and face less convex, the areolet 
usually complete and the transverse impressions on the basal abdominal 
segments less conspicuous. 
Sweden, France and Germany, where the male has been bred by 
Brischke (Schr. Phys. Ges. Konig. 1871, p. 89) ‘‘aus Fenusa-Larven in 
Eichenblattern ’—referred to Henusa pygmaea by Cameron (i. 298). It has 
not before been noted in Britain, but I possess half-a-dozen examples 
from Shere in Surrey in Dr. Capron’s collection. 
3. albipes, Ruthe. 
Grypocentrus albipes, Ruthe, Stett. Ent. Zeit. 1855, p.56; Holmgr. Sv. Ak. 
Handl. 1855, p. 194, ¢ 2. 
Very shining, subpubescent and black, with palpi white and mandibles 
rufescent. Head not posteriorly constricted and almost broader than 
thorax ; face smooth and prominent; clypeus subelevated and apically 
rounded. Antennae basally rufescent beneath. Thorax nitidulous with 
discal metanotal areae distinct; petiolar area large, smooth and sub- 
vertical. Scutellum discally depressed. Abdomen not discally pale- 
marked ; basal segment gradually dilated apically, margined, not short, 
with somewhat distinct carinae. Legs rufescent with hind coxae basally 
black-marked above. Wings with stigma large and areolet pentagonal ; 
nervellus intercepted below centre. Length, 4 mm. 
Closely allied to G. cénc/ellus but differing in its hardly punctulate and 
much more shining body, paler legs and the entirely black upper side of 
the abdomen; it is one of the most nitidulous species of the genus. 
On the Continent it is recorded from Germany, Sweden and France. 
Bridgman introduced this species as British (Trans. Ent. Soc. 1882, p. 158) 
under the erroneous name G. zucisulus, Ruthe, an account of a specimen 
he took near Norwich in August, 1877; the same insect is referred to “ G. 
albipes or a new species” by ‘Thomson, to whom it was sent (/oc. c7t. 1886, 
p- 359); but doubt of its identity appears to have been subsequently 
eliminated, for we find Bridgman writing (Trans. Norf. Soc. 1893, p. 62) 
of Fenusa pumilio, ‘from this sawfly I have bred a small Ichneumon, 
Grypocentrus albipes, R.”; and again (é.c. 1894, p. 627) “ Bred from 
Fenusa pumilio”’ and taken at Lakenham and Earlham in Norfolk. I have 
a female from Shere in Capron’s collection. 
4. anomalus, Brisch. 
Grypocentrus anomalus, Brisch. Schr. Phys. Ges. Konig. 1871, p.89, ¢; Schr. 
Nat. Ges. Danz. 1878, p.94, 3 ?. 
A black and shining species, with the abdomen centrally red and cly- 
peus apically flavous. Antennae as long as head and thorax, with the 
scape red beneath. Metathorax short with indistinct areae. Scutellum 
black. Abdomen also black with the third to fifth segments red, often 
black-marked in the @; basal segment punctate, almost shorter than 
broad ; second dull and finely punctulate. Anterior legs red with the
