Bassus | BRITISH ICHNEUMONS. 85 

am not aware that it had been bred, till Mr. H. J. Charbonnier kindly 
gave me a female together with the puparium, from near the capital 
extremity of which it had emerged, labelled, “ bred from pupa of P/a/y- 
chirus albimanus on 6th August, 1909, at Shepton Mallet in Somerset- 
shire.”

A punctulate and somewhat shining species. Head with the mouth, 
disc or in ¢ whole of clypeus, internal orbits or in @ whole face, flavous ; 
frons smooth and canaliculate. Antennae black, filiform and shorter than 
the body with flagellum ferrugineous beneath ; scape of ¢ flavous beneath. 
Thorax black, stout and gibbous, with a mark before and short line 
beneath the radices flavous; pleurae strongly nitidulous and obsoletely 
punctate ; metathorax rugulose with the areae obsolete and areola very 
small. Scutellum and postscutellum flavous. Abdomen deplanate, black 
with the second to fourth segments more or less broadly, usually with 
their apical half, red or badious and transversely impressed; basal seg- 
ment scabriculous, basally impressed and in 9 apically white; the gas- 
trocoeli of the second distinct; terebra subexserted. Legs fulvous; 
coxae flavous with the hind ones always basally black ; hind tibiae broadly 
white with the base and before apex black, the extreme apex at least in- 
ternally being red. Wings slightly clouded with the stigma and radius 
infuscate, tegulae and radix flavous. Length, 5 mm. 
Pfankuch thought &. delefus synonymous with 2. multicolor, Holmgr., 
but distinct from 4. multicolor, Grav.; he gives no distinctions. 
This is certainly a rare species; Gravenhorst knew but three females, 
captured in Piedmont; Holmgren records it from Sweden in August ; 
Thomson from Denmark; Brischke the male from Prussia; Tosquinet 
gives it from Belgium ; and it is by no means rare in India. It has long 
stood in our lists, but the earliest record | can find is by Rev. E. N. 
Bloomfield in the Natural History of Hastings, where it is recorded from 
Guestling in the znd Supplement, p.9, under the name #. picfus, Gr., cor- 
rected in the 3rd Supplement, p. 14, and by me in the Vict. Hist. Sussex. 
Bignell has captured it at Crabtree in Devon, on 28th August; there are 
three males in Dr. Capron’s collection, probably from Shere in Surrey. 
My own experience extends to the capture at Horning Ferry in the Nor- 
folk Broads of eight males on the 15th June, rgor1, and another specimen 
of the same sex in Tuddenham Fen, in Suffolk, on the 19th of the same 
month; it is certainly extremely local and probably confined to very 
marshy places. It has not yet been bred.
