Head .shining and tran.sver.se; epistoma prominent, clypeus distinctly 

 discreted, mandibles somewhat broad, with the teeth sub-equal ; froiis 

 deeply canaliculate semicircularly above scape. Antennae short ; flagellum 

 two-thirds length of body ; ba.sal flagellar joint thrice longer than broad, 

 the apical ones quadrate. Thorax black, longer than high, dull, closely 

 and distinctly punctate, with notauli distinct ; metathorax nitidulous with 

 irregular rugosities ; petiolar area not discreted, sub-hexagonal ; lateral 

 areae entire ; apophyses short and acute. Scutellum elongate, basally 

 carinate. Abdomen sub-ovate, black ; basal segment stout and with base 

 of second transversely rugose ; remainder shining and transverse ; post- 

 petiole sub-parallel-sided. Legs slender ; front ones dull ochreous with 

 coxae and trochanters, except apices of latter, black ; posterior legs black, 

 with apices of trochanters pale, femora and tibiae piceous, the latter 

 becoming paler basally. Wings with radix pale, stigma normal and piceous ; 

 areolet pentagonal, externally wanting ; discoidal recurrent nervure and 

 lower half of transverse discoidal nervure wanting ; transverse ordinary not 

 interstitial ; hind wing with lower nervures obsolete and the nervellus not 

 intercepted. Length, 3 mm. 



The shape of the abdomen resembles that q{ H. fulvipes, but the legs 

 are more slender, the neuration is distinct, and the basal segment narrower. 



The only known exponents of this species are two males bred from the 

 egg-bags of a spider which Bridgman found at Norwich in a rolled-up 

 nettle leaf, protected by the spider herself; one parasite was developed 

 from each sac.
