156 BRITISH ICHNEUMONS. [He?niteles. 



apically truncate, straight and broad. Antennae with scape of S white 

 beneath. Pronotum not carinate. Abdomen black, witli the third seg- 

 ment basally fulvo-stramineous ; basal segment aciculate, terebra longer 

 than the slender petiole. I>egs fulvous ; ^ with anterior coxae, except 

 the intermediate ones above, and trochanters white ; hind coxae above, 

 their tarsi and apices of their tibiae infuscate. Wings sub-hyaline, stigma 

 and costae piceous ; radix and tegulae white ; areolet wanting ; nervellus 

 antefurcal. Length, 4-5 mm. 



In conformation like //. si/ni/is, but the white mandibles and straightly 

 truncate clypeus are very distinct. Thomson says this species may be 

 known by the head being somewhat narrowed behind the eyes, the frons 

 and mesonotum densely and very finely punctate and pubescent though 

 not dull, the metathoracic lateral costae entire, petiolar area shining and 

 not discreted, wings hyaline with antefurcal nervellus, antennae elongate 

 and filiform and brown, clypeus deeply discreted and immarginate, with 

 the apex in the ? nearly emarginate, and in ^ quite truncate, and by the 

 quadrate, obsoletely and sparsely punctate second segment. 



Probably not uncommon, and occurring in the middle of May, through- 

 out north and central Europe. Earlhani and Eaton, Norfolk, in May, 

 August and September (Bridgman).

$ . Head with palpi stramineous and clypeus not discreted. Antennae 

 sub-filiform with the joints confluent, as long as body and sometimes 

 basally ferrugineous beneath. Metathorax with two transverse but no 

 lateral costae, slightly rugose centrally. Abdomen fusiform, as broad as 

 thorax, black, third segment red or stramineous with a transverse black 

 line before apex, the second concolorous apically and usually with two 

 basal castaneous dots but sometimes entirely black, remainder occasionally 

 red-margined ; post-petiole parallel-sided, hardly longer than broad and 

 nearly as long as the explanate petiole ; second punctate. Legs pale red, 

 with coxae, except usually apices of the anterior, black ; hind tarsi, apices 

 of their tibiae, and their femora except basally, nigrescent. Wings some- 

 what ample and clouded ; stigma piceous, radix and tegulae stramineous. 

 Length, 3-5 mm. 



Gravenhorst mentions a var. with the scape, coxae and only margins of 

 two basal segments, red. 



9 . Head finely rugose, somewhat shining, black. Antennae as long 

 as body, attenuate from centre, and basally red. Thorax finely rugose, 

 somewhat shining, with mesonotum dull and notauli distinct; metathorax 

 smooth, with two transverse costae ; petiolar area small and not discreted. 

 Abdomen nitidulous, black, with third segment except discally red, and 

 the fourth laterally paler, anal segments apically fiavous ; basal segment as 

 long as terebra, sub-glabrous with obsolete carinae ; second segment finely 

 and sparsely puncate, and aciculate basally. Legs slender, fulvous, with 

 anterior coxae and trochanters whitish ; hind coxae black, with their tarsi, 

 apices of their femora and tibiae, piceous. Wings hyaline, with stigma
