l68 BRITISH ICHNEUMONS. [Hemi/eies. 



The 6 has the antennae more filiform and the abdomen more cylindrical, 

 and the three basal segments coriaceous with the petiole bicarinate. 

 Bridgman says that the species appears to be allied to //. gracilis, Thoms. 



The original specimens were bred by \V. H. B. Fletcher from spiders' 

 nests, taken at Worthing, which swarm on the coast. I possess both sexes 

 from Dr. Capron's collection, together with a female variety having the 

 post-petiole distinctly explanate, the areola strongly transverse and the 

 second recurrent nervure of the upper wing wanting.

 Hemiteles gracilis, Thoms. O. E. x. 989 ; Schm. Term. Fiiz. 1S97, p. 546, i 9 . 



A slender, shining species with red abdomen. Head obsoletely punc- 

 tate with the vertex somewhat broad ; clypeus sub-compressed, mandibles 

 not stout. Antennae basally and beneath pale, with the scape sub- 

 globose and excised. Mesonotum nitidulous with distinct notauli ; meta- 

 thorax shining and somewhat smooth with complete costae ; areola 

 hexagonal, apically truncate, basally contracted ; apophyses wanting. 

 Abdomen glabrous and nitidulous, more or less discally fulvous ; basal 

 segment aciculate or coriaceous, usually strongly bicarinate throughout ; 

 petiolar spiracles behind the centre, second segment with epipleurae 

 obtuse ; terebra almost shorter than the narrow petiole. I^egs pale. 

 Wings hyaline ; radial nervure elongate, basally emitted from the centre 

 of the pale stigma ; discoidal cell apically longer than broad, with its 

 lower angle nearly rectangular and emitting the median nervure from 

 below its centre ; nervellus strongly post-furcal and not intercepted. 

 Length, 3-4 mm. 



This species is very closely allied to H. micator, with which Bridgman 

 confused it, but it differs in having the nervellus not intercepted and the 

 pedicellus mutic. 



It was first recorded, without locality (Trans. Ent. Soc. 1886, p. 340), 

 from Britain, on Professor Thomson's authority ; subsequently Bridgman 

 tells us that he took the specimens commonly in Norfolk, at Brundall and 

 Norwich, and that it has been bred from spiders' nests. Bignell has 

 captured it at Bickleigh and Plympton in Devon, in September ; and 

 there is a long series of females in Capron's collection from Surrey. 

 Col. Yerbury has given it to me from Nairn, in July ; Tuck several from 

 Tostock in Suffolk, early in September, 1900 ; and I took a male at 

 Hickling Broad in the following June.

A small and strongly nitidulous species. Head with the palpi and 

 mandibles stramineous. Antennae elongate, filiform ; of $ with the 

 excised and sub-globose scape more or less, and usually the flagellum, 

 rufescent beneath ; the joints not apically nodulose, pedicellus distinctly 

 dentate internally. Thorax black or obscurely badious, with distinct and 

 elongate notauli ; metathorax coarsely rugose with costae and apophyses 

 strong. Abdomen elliptic with the second, usually third and very rarely
