1ig2 BRITISH IGHNEUMONS. [ Zryphon 

4. exclamationis, Grav. 
Tryphon exclamationis, Gr. I. E. ii. 279, excl. 9. T. confinis, Holmgr. Sv. 
Ak. Handl. 1854, p.77; lib. cit. 1855, p.191; Brisch. Phys. Ges. Kénig. 1871, 
p.88, ¢. T. helophilus, Thoms. O. E. ix. 899, ¢ ? (mec Grav.). 
Pfankuch, in examining Gravenhorst’'s types, found that this species 
differs from 7. helophilus only in its rugosely punctate and hardly shining 
frons, strong longitudinal scutellar carinae, finely rugose metathorax 
with no costulae, rather darker legs with basally infuscate trochanters, 
flavous ¢ face, and in having the basal segment almost entirely and the 
two following basally scabriculous. Length, 7—8 mm. 
So frequently taken with the above species both here and in Sweden 
that it is difficult to credit its distinction. Bridgman first noticed it in 
Britain (Trans. Ent. Soc. 1882, p. 158), at Brnndall in September; and, 
although not since recorded, it is by no means rare in marshes on JZentha 
hirsuta, Heracleum and Angelica flowers, on rushes, and once I captured a 
male flying low among marram grass on the coast sandhills at Pakefield 
in Suffolk, where it has occurred to me from 17th August at Foxhall (on 
Sparganium with the last species), Lackford and at Metton in Norfolk, 
to early September, when Tuck has taken it at Tostock. I believe it to 
be local.

ix. 896. T. atriceps, Ste. Illus. Man. vii. 262, ¢. 
A shining and black species, with the anus entirely red and metathorax 
glittering. Head not posteriorly contracted; the mutic frons and face 
strongly punctate; clypeus hardly elevated behind its centre, apically 
broadly rounded and, like the mandibles, rufescent. Antennae filiform, 
much shorter than body, testaceous beneath. Thorax stout, shining and 
almost narrower than head, notauli wanting; metathorax discally very 
strongly nitidulous, quite smooth and laterally foveate, with the petiolar 
area equally glabrous and shining, its basal carina strongly elevated and 
subreflexed; longitudinal carinae entirely wanting, the transverse strong 
and arcuate with costulae distinct; spiracles large and suboval. Scutel- 
lum punctate, deplanate and margined to apex. Abdomen parallel-sided, 
red with only its base black; basal segment black, with its apex red and 
carinae obsolete. Legs red with coxae, base of trochanters, anterior 
femoral marks and, except rarely in ? , hind femora black; apices of their 
tibiae and tarsi rarely infuscate; anterior tarsi and tibiae flavidous-red. 
Length, g—12 mm. 
At once known by the peculiar metathoracic structure, very similar to 
that of 7. brachyacanthus, and so distinct that it doubtless constituted the 
feature upon which Forster’s genus Pszlosage was founded, though the 
present differs in no other way trom more typical species of Zryphon. I 
have examined Stephens’ type; but it would be ridiculous to concede him 
priority upon a feature not referred to in his description. 
Doubtless not rare in north-west Europe, though hitherto known only 
by Gravenhorst’s records, and from Sweden and France; Giraud once 
bred it from Selandria (Periclista) melanocephala, a common British sawfly.
