sub-buccate and not long; clypeus apically mutic, mandibles basally raised 

 and tuberculate. Antennae longer than half the body, slender ; of 9 

 sub-fihform, black, with the flagellum basally testaceous, its basal joint 

 linear and thrice longer than the sub-globose scape which, with the pedi- 

 cellus, is dull testaceous ; of 6 black, apically sub-attenuate with the 

 joints somewhat discreted. Thorax somewhat elongate ; mesonotum 

 shining, densely and very finely alutaceous, with indistinct notauli ; meta- 

 thorax sub-rugosely punctate with complete areola, emitting costulae 

 before its centre. Abdomen of ? oblong, of $ strongly elongate, not 

 very convex and apically sub-dilated ; segments two to four red and 

 smooth, but not apically callose ; basal segment somewhat curved and 

 broad, sub-rugose throughout, with no dorsal carinae ; tubercles only just 

 behind the centre ; second segment obviously, third and fourth hardly, 

 punctate ; terebra almost shorter than the basal segment. Legs slender, 

 fulvous with the tarsal claws small and S coxae black. Wings griseous- 

 hyaline, of $ with a small cloud before the incomplete and not large 

 areolet ; tegulae and stigma black, latter basally pale and not broad, 

 emitting the short and curved radial nervure a little beyond its centre ; 

 nervellus hardly antefurcal. Length, 4 mm. 



This species is allied to H. floricolator, but differs in the apices of the 

 segments not being callose, the basally tuberculate mandibles, the colour 

 of the legs and the rugose petiole. 



Bridgman records (Trans. Ent. Soc. 1886, p. 104) a female of this 

 French species from the now demolished Heigham osier carr, near 

 Norwich, in August.

A narrow and strongly elongate species. Head witli the mandibles and 

 labrum badious ; clypeus discreted, apically straight and sub-reflexed. 

 Antennae slender, filiform and rather shorter than the body. Thorax 

 cylindrical ; metathorax elongate and irregularly rugose, with the areola 

 elongate-hexagonal and the petiolar area discreted. Abdomen narrower 

 than the thorax, with segments two to six parallel-sided ; basal segment sub- 

 linear, post-petiole aciculate, twice longer than broad and a little broader 

 than the elongate petiole ; segments two, three except sides and apex, and 

 the base of the fourth, stramineous or fulvous ; terebra half the length of 

 the abdomen. Legs slender ; the anterior ferrugineous with the coxae 

 and trochanters basally black and the femora testaceous, infuscate to 

 beyond their centre ; hind ones black, with apices of the trochanters and 

 base of the tibiae ferrugineous. ^^'ings normal, hyaline ; stigma and costa 

 piceous, radix and tegulae dull stramineous ; areolet pentagonal with the 

 outer nervure obsolete. Length, 5 mm. 



Taschenberg says it has been bred from the galls of Rhodites eglanteriae^ 

 Hart., and Bridgman raised both sexes from the cocoons of Apanteles 

 ^lomeraius upon Pieris brassicae^ probably at Norwich. It is said to occur 

 in May, and is common in Norfolk ; and Bignell has captured it at Dous- 

 land in Devon, towards the end of August. On the (Continent, where 

 Siebold has bred it from Fumca intennediella^ it is onl)' recorded fiom 

 Germany.
