102 BRITISH ICHNEUMONS. 



Harwood has bred it from Lycaena Tolas, probably at Colchester.^ It has 

 been bred from Depressaria heracleana (Entom. 1884, p. 70) ; and the 

 van fa/lax from Mania typica. The female would appear to be of much 

 rarer occurrence than the male, and I have not seen an example of it.

Head strongly punctate, black ; mandibles and margin of clypeus red ; 

 vertical, and in $ facial, orbits white. Antennae black, of ? slightly 

 attenuate, white-banded, scape red, rarely black beneath ; of $ with the 

 basal six joints usually reddish beneath. Thorax strongly punctate, black ; 

 pronotum and callosity beneath tegulae white ; metathorax obtusely bi- 

 dentate, its areola semi-lunar and apically strongly arcuate, shorter in c? . 

 Scutellum, and in $ often post-scutellum, white. Abdomen of $ sub- 

 linear ; black, strongly compressed and attenuate apically in $ , eighth 

 segment often exserted ; the very finely and closely punctate second and 

 third segments, as well as the apex of $ post-petiole, red ; fourth to 

 seventh more or less shining and white-marked ; post-petiole strongly and 

 rugosely punctate ; gastrocaeli small and striolate. Legs black ; anterior 

 femora, tibiae and tarsi, and in $ base of hind tibiae, red ; all the tibiae 

 spinulose. Wings infuscate-hyaline ; stigma ferrugineous ; tegulae piceous, 

 with white dots; areolet narrowed above. Length, 8- 11 mm. 



The female is at once known by its spinose tibiae and compressed 

 anus ; and the male differs from B. vestigator in the narrower areola, the 

 black post-petiole and hind tibiae. 



Stephens records this species, under the name of viilitaris, from London 

 and Salop, not very common in the spring. I have seen a male, which 

 had the orbits immaculate, and was taken at Copdock, Suffolk, in May. 

 The female hibernates. It occurs in France, Germany and Hungary.

A rather small, shining, red and black species. Head black, face some- 

 what protuberant; frons punctate and shining; mandibles and angles of 

 clypeus, which latter is glabrous with a few scattered punctures, not 

 separated, and apically truncate, sometimes red ; lunulae at vertex 

 generally distinctly white ; $ has also the palpi, sides of clypeus and of 

 face, somewhat broadly white. Antennae black, of $ stoutish, filiform, 

 not dilated, white-banded : of $ slender, joints somewhat nodulose, 

 fulvous, with scape more or less white, beneath. Thorax black, punctate 

 and shining; $ with pronotum, and sometimes callosities at radix, white; 

 sternauli indicated ; areae of metanotum complete ; areola semi-oval, 

 slightly longer than broad, glabrous, with the base and apex evenly 



1 The record of this species from Guestling (Nat. Hist. Hastings, 3rd suppl., p. 14) is an error.
