Tryphon] BRITISH IGHNEUMONS. 185 

Very like the preceding but with the frons not at all striate, strongly 
impressed above the scrobes and its central sulcus obsolete, the metanotal 
areae usually entire and face entirely black; from T. braccatus, Gr., Holm- 
gren says it differs in having the anterior legs red, not pale stramineous, 
but I do not think he knew the true 7: dracca/us, which Pfankuch assigns 
to Psrlosage with no longitudinal metanotal areae, since he says the areae 
are more or less complete. 7. éracca/us was introduced as British by 
Marshall, doubtless on the strength of a single ¢ of Holmgren’s species 
taken at Nunton in Wilts, and, since no one has found the true species, 
represented in Gravenhorst’s collection by a broken @, it must be omitted 
from our List. 
Not a very common species with us, though its Continental distribution 
is broad. It has been found in the New Forest (Miss Chawner), Shere 
(Capron), Yorks (Bradford Sc. Journ. 19¢8, p. 71), Nunton (Marshall) 
and Norwich (Bridgman); I have found it on 6th June on flowers of 
Chaerophyllum sylvestre, later on those of Heracleum, towards which I noticed 
that they dart very swiftly and are not seen till they hover quite close to 
the flower, upon which they alight gently on the under side and then 
clamber up onto the flower-table ; later still they frequent Amgelica, up to 
22nd August. I have found it at Epsom, Lyndhurst and Hinchelsea in 
the New Forest, where a male was taken by Lyle, flying low over heather 
in the evening ; at Wroxall in Isle of Wight ; and at Lackford, Hadleigh, 
Monks’ Soham, and Wherstead in Suffolk. Yerbury took it at Glengariff 
in Co. Kerry in June, 1901 (misnamed 7. draccafus, E.M.M. 1902, p. 55) ; 
and Elliott has given me both sexes from Skene Park and Banchory in 
the Highlands, taken in August. 
9. signator, Grav. 
Tryphon rutilator, var.4, Gr. I. E. ii. 309, ¢. T. signator, Gr. lib. cit. 301; 
Ste. Ill. M. vii. 261; Holmgr. Sv. Ak. Handl. 1855, p.189; Voll. Pinac. pl. 
xxii, fig. 7; Thoms. O. E. ix. 898, ¢ ¢. T. facialis, Ste. Ill. M. vii. 263, 3. 
Somewhat shining and black with mouth, apex of clypeus and a trans- 
verse central fascia, often centrally interrupted, on the face flavous ; 
clypeus transversely elevated behind its centre; frons very closely and 
subrugosely punctate. Antennae flavidous beneath. Metanotum with 
three or five distinct areae. Abdomen red, with the first segment black 
and anus often infuscate; basal segment somewhat narrow, with the 
carinae very determinate and extending beyond its centre. Legs tes- 
taceous with coxae, base of trochanters and apices of hind tibiae black. 
Areolet petiolate and subtransverse. Length, 7—10 mm. 
Superficially not to be distinguished from 7. ru/ilator, but at once 
known by the simple scrobes and from all the remainder of the genus by 
the peculiar facial fascia, often centrally interrupted and so forming two 
dots below the antennae. My only Scots specimen isa g, taken by Mr. 
Adie Dalglish at Cadder in Lanark on roth June, 1900, and is remark- 
able in having these facial marks linear and oblique. I have seen the 
type of 7. facials. 
One of our commonest species, occurring earlier than is usual in this 
genus; it is almost confined to June, my earliest date is 27th May, and it 
is not found after the first week in July; I have never seen it attracted by 
flowers and my forty odd specimens were met with by sweeping grass and
