BRITISH ICHNEUMONS. 6g 



is somewhat scabriculous, the areola semi -circular and incomplete 

 apically ; the spiracles short, elliptic. The apex, or more rarely the 

 whole apical margin, of the scutellum, white. Abdomen red with the first, 

 the basal two-thirds of the second, and often an obscure discal spot on the 

 remaining segments, more usually on the apical ones, black ; the post- 

 petiole is remotely punctate or nearly entirely glabrous ; gastrocaeli 

 obsolete, red, closely punctate. The anterior legs are fulvous ; the hind 

 ones black, with the base of the tibiae and femora and the apex of 

 trochanters more or less red ; all the coxae usually white-marked beneath. 

 Wings a little iridescent ; stigma piceous ; tegulae and radix white. 

 Length, 8-10 mm. 



This species may at once be distinguished from the preceding by the ? 

 having the frontal orbits always red, and the S no pale antennal band ; the 

 metathoracic spiracles also are smaller, the apex of the scutellum is white 

 in the S , red in the ? , which latter has the post-petiole more finely punc- 

 tate and shining, and the S has much more white marking on its head, 

 thorax and legs. 



The S appears to be of much more frequent occurrence than the ? , 

 which Gravenhorst placed under a distinct name in the genus Fhygadeuo?i, 

 on account of its exserted terebra. The former I have beaten from oak 

 trees, in Bentley Woods near Ipswich, and from young birches, in Assing- 

 ton Thicks, in May, and Tuck took it on Chaerophylluiii flowers, at Bury 

 St. Edmunds, on 5th June ; Stephens says it is common about London, 

 and that it has been found in Salop, &c. ; Hope took it at Netley. Bignell 

 captured this species at Plym Bridge, and it is also said to have occurred 

 at Alphington in Devon, on May 20th ; Beaumont has found it at Lewisham, 

 early in June ; Bridgman says it is not uncommon around Norwich, and it 

 is recorded from Essex. I do not find that it has ever been bred,

9 . Head black, palpi white ; mandibles, labrum, clypeus, apex of the 

 cheeks, centre of the face and its margin below the antennae, fulvous ; 

 orbits pale near antennae. Antennae stout, filiform, attenuate towards 

 base, blackish ; the basal joints rufescent, at least below, and the central 

 band white. Thorax black, with callosities at the radix fulvous ; meta- 

 thorax with complete upper areae, the areola being semi-circular, the 

 petiolar area concave. Apex of scutellum yellowish-white. Abdomen 

 very smooth, blackish ; second segment with mark before base and apical 

 margin red ; the remainder badious, apically red, the seventh is said to be 

 entirely dirty yellow above ; post-petiole smooth and shining ; second 

 segment strongly punctate at the base, with distinct transverse thyridii 

 and obsolete gastrocaeli ; terebra only just exserted beyond the seventh 

 segment. Anterior legs stramineous ; the hind ones have the coxae black 

 with their apices and the trochanters stramineous, femora stout and red, 

 becoming darker apically, tibiae pale flavous or whitish, rufescent apically; 

 tarsi red-yellow ; hind coxae with many elevated oblicjue lines (cristulae) 

 beneath. Wings sub hyaline, stigma fulvous, tegulae red.
