176 BRITISH [CHNEUMONS. [ Trematopy gus 


apically broad, at its base sulcate and strongly bicarinate; second a little 
impressed centrally on either side; terebra not exserted. Legs normal, 
the anterior fulvous with coxae and base of trochanters black, hind ones 
black with apex of trochanters and tibiae except at apex and extreme 
base testaceous. Wings nearly hyaline with stigma testaceous, radix and 
tegulae white; areolet irregularly triangular, elongately petiolate, rarely 
obsolete; nervellus intercepted below its lower third. Length, 8 mm. 
It occurs on the Continent in May and June; Brischke (Schr. Phys. 
Ges. K6nig. 1871, p. 87) bred a 9 from larvae of Dolerus gonager and 
Gaulle adds Loderus vesiigial’s as a French host. Stephens took it at 
Hertford in July, 1835, and near London; there is a long series in Mus. 
Brit. from his and Desvignes’ collections, with others found by Marshall 
at Govilon in South Wales and Nunton in Wilts. | Capron took a couple 
of 2 9 at Shere in Surrey, but neither Bridgman nor | have met with it.

A somewhat dull species with face black and the red second and third 
segments scabrous. Head transverse, subbuccate, punctate and black ; 
palpi and mandibles alone, or also apex of clypeus, testaceous ; frons 
rugosely punctate, deplanate, carinate; face centrally a little convex, punc- 
tate ; clypeus subdiscreted, shining, sparsely and coarsely punctate, and 
apically subtruncate. Antennae filiform and a little shorter than body ; 
flagellum fulvous, apically darker, with two basal joints subequal. 
Thorax narrower than head, a little shining and black; notauli distinct, 
pleurae subaciculate; metanotal areae distinct, areola centrally curved, 
lateral areae large, costulae rarely indicated. Scutellum black. Abdomen 
black with second and third segments transverse, coriaceous and more or 
less, or in @ entirely, red; fourth basally or mainly red; basal segment 
subcurved, scabriculous, black and discally a little sulcate, @ spiracles 
somewhat prominent ; terebra curved and not exserted; ¢ hypopygium 
emarginate and valvulae sometimes exserted. Legs slender and red with 
coxae, except sometimes front ones, black. Wings subinfumate with 
stigma and tegulae nigrescent, former basally and latter apically pale ; 
radix stramineous; areolet wanting; nervellus oblique and intercepted 
far below centre. Length, 5—6 mm. 
The abdomen is said to occasionally be dark castaneous throughout, or 
the 9 may have the mouth and apices of hind femora infuscate. 
This species appears to have only been found in any numbers by Holm- 
gren in northern Sweden, though Grav. took a couple of males about 
Breslau in May, Gaulle records it from France and Brischke from 
Prussia. It has stood in our list since 1870, but I know not upon what 
authority, and should have regarded it with some suspicion had not 
Bridgman named an example for Bignell, taken by the latter “at ‘Tavis- 
tock Road, 4th August,” in south Devon.
