BRITISH ICHNEUMONS. 239 



with the head and thorax red, the metanotum, abdomen and legs for the 

 most part, black. Thomson says the colour of the capital and thoracic 

 markings is not flavous in the typical (J, but white or lacteous. 



This species, which is somewhat widely distributed on the Continent, 

 appears to be represented in Britain by a single specimen, which Fitch 

 says is in the National Collection, from that of Desvignes ; and it must, 

 consequently, though very likely to occur with us, be at present regarded 

 with due reserve as indigenous.

Similar to the preceding. Head black, with the cheeks sub-sinuate and 

 sub-reflexed ; palpi, mandibles, the apically mutic clypeus, face, frontal 

 and apex of external orbits, white. Antennae with flagellum flavous, and 

 scape white, beneath. Pronotum and lines before and beneath the radix 

 white ; metathoracic apophyses small. Scutellum white. Abdomen red, 

 with the petiole black ; post-petiole punctate throughout. Legs black, the 

 anterior coxae and trochanters white beneath ; anterior femora and tibiae, 

 and base of hind femora, red. Stigma black ; radix and tegulae white. 

 Length, 6 mm. 



Thomson, in the " Annales," considered this species to be the (^ of 

 A. flammeohis, Wesm., but, since M. Pic has more recently discovered the 

 true $ of that species in Switzerland, A. inclytus is still accounted a good 

 species, of which the $ is at present unknown. 



It was first recorded from Britain, by Bridgman (Trans. Ent. Soc. 1886, 

 p. 336), on the strength of a specimen, taken by Thouless, at Lakenham, 

 near Norwich ; and he himself subsequently captured it at Earlham, in the 

 same neighbourhood, in July. On the Continent it appears to have only 

 been found in Prussia and the northern districts of France.

Head hardly narrowed behind the eyes ; vertex rather broad ; clypeus 

 sub-discreted and densely punctate, apically rounded or sub-truncate ; 

 mandibular teeth unequal, the upper being large and somewhat acuminate, 

 the lower very small ; face moderately convex. Antennae filiform and 

 distinctly short ; scape sub-cylindrical, hardly emarginate apically. Pro- 

 notum densely punctate ; metanotal areae distinct and complete ; areola 

 sub-pentagonal. Abdomen elongate-sub-fusiform ; petiole somewhat short 

 and deplanate ; post-petiole strongly dilated and usually punctate ; gas- 

 trocaeli of variable depth ; thyridii distinct and transverse. Legs some- 

 what stout ; calcaria long ; coxae mutic. Areolet narrowed above ; 

 discoidal cell with its lower angle hardly acute ; nervellus oblique, ante- 

 f ureal.
