188 BRITISH ICHNEUMONS. [ Zivphon 

ture I am able to attest through the remarkable capture of twenty 
specimens among many more seen flying about and settling upon the 
sacred doorand door-posts of the chapel upon the extreme top of Croagh 
Patrick in Co. Mayo (whence St. Patrick is still locally believed to have 
banished snakes from Ireland); the sun was at meridian heat and one 
must suppose the insects to have been drawn up by some air current to this 
altitude of 2,510 feet, for no attraction was apparent, and their normal 
habitat was doubtless the boggy peat pools but little above sea level, 
where I swept it from reeds at the adjacent Carramore Lake a few days 
later, on 18th July, 1910. 
I describe the varietal form above since it is much commoner than the 
type, which differs from all the foregoing species in its red hind femora 
and simple scrobes. Pfankuch gives a good table of the species with red 
hind femora and regards both 7% consobrinus and 7. incestus, Holmgr., as 
little more than varieties of 7. drunniventris, Gr.; he makes, however, no 
mention of frontal puncturation, by which the former is at once recog- 
nised from the two latter and these are certainly synonymous, since the 
whole sculpture and facies are identical, though I have seen no inter- 
mediate forms. 
T. brunniventris has long stood in our List, but I can find no records of 
capture and it is certainly rare, much more so than its variety. I possess 
but half a dozen examples, captured at Irvine Moor near Glasgow by 
Dalglish, and at Tostock with var. zmcestus in July by Tuck; it has 
occurred to me on Angelica flowers at Lackford and on those of wild 
carrot at Tuddenham in Suffolk, at the end of August.

A black species, with the mouth and usually clypeal apex rufescent ; 
clypeus transversely subcarinate centrally, frons deplanate and strongly 
punctate. Antennae rufescent towards their apices beneath. Metanotal 
areae strong and entire, with distinct costulae. Abdomen black with 
only apical margins of the segments very narrowly castaneous ; basal seg- 
ment not broad, slightly depressed before its apex, with distinct and 
basally strong discal carinae extending to its centre; terebra narrow. 
Legs red, with only coxae and apices of hind tibiae black. Areolet 
usually a little petiolate, emitting recurrent nervure from its extreme apex ; 
nervellus strongly postfurcal, intercepted a little above its centre. Length, 
7—10 mm. 
The only British species of the genus with black abdomen and known, 
as Pfankuch says of the type, by the broad stigma and straight second 
recurrent nervure which is emitted from the apical angle of the areolet. 
It is found somewhat uncommonly on the Continent among oaks in 
May. ‘Taken, but very rarely, near London, in June” (Stephens, whose 
only example now extant is a Q Mesoletus; there are with it in Mus. 
Brit., however, half a dozen examples correctly named by Desvignes). It 
is undoubtedly very infrequent with us, and there are no later records; I 
am, nevertheless, able to confirm it as British by the capture of an example 
on bushes on 27th June, 1900, in the Bentley Woods near Ipswich, the 
only one taken during a ten years research of the same spot.
