Hetnite/es.] BRITISH ICHNEUMONS. 1 25 



pubescent ; basal segment gradually explanate throughout, spiracles not 

 prominent, of ? densely and of 6 obsolctely aciculate ; second segment 

 conlkiently punctate longitudinally, of 6 quadrate and of 9 transverse ; 

 third distinctly punctate ; apical margins of the first three segments trans- 

 versely sub-impressed, sub-callose and, together with the remainder of the 

 abdomen, glabrous ; terebra one-third the length of the abdomen. Legs 

 slender, pale fulvous, with the trochanters and anterior coxae flavous ; 

 sometimes the tarsi, posterior femora and tibiae, apically infuscate. Wings 

 with the areolet externally incomplete ; tegulae, stigma and radix stra- 

 mineous ; nervellus indistinct, antefurcal. Lengtli, 4-5 nun. 



Bridgmaii says this species is rendered distinct by the peculiarly elongate 

 and often indistinct areola, the pale margin of all the segments and the 

 longitudinal puncturation of the second ; but it is very closely allied to 

 H. julvipes and H. subnuirginatus in its carinate and foveate pronotum, 

 and impressed segments ; the antennae are, however, longer and the areola 

 less distinctly defined ; it has the pale incisures of the latter and the broad 

 post-petiole of the former. I am strongly of o[)inion that these three 

 species are but forms of a single one. 



The types of this species were taken by Peter Cameron, probably 

 near the Clyde ; and I possess others from Surrey and Hertfordshire in 

 Capron's and Piffard's collections. Schmiedeknecht tells us it has been 

 bred from Chrysocorys festaliella.

Head transverse, slightly narrowed posteriorly, somewhat shining, very 

 finely and closely punctate ; clypeus indistinctly discreted from the pubes- 

 cent face ; mandibles stramineous with the upper tooth only slightly the 

 longer. Antennae of $ sub-fusiform, with the basal flagellar joint about 

 thrice longer than broad, the second and third of equal length ; of $ 

 filiform, somewhat shorter than the abdomen ; scape more or less stra- 

 mineous beneath. 'I'horax dull, finely reticulate ; mesonotum with the 

 notauli reaching the centre ; metathorax somewhat short, with two curved 

 transverse costae and ^\y\<i longitudinal aciculation ; an anteriorly curved 

 and explanate areola sometimes indicated by lateral costae; petiolar area 

 discreted. Abdomen elongate, with the central incisures sub-stramineous, 

 of 9 sub-ovate; basal segment aciculate throughout, thrice longer than 

 apically broad, wider in $ ; spiracles not prominent ; post-petiole obso- 

 letely bicarinate ; second segment basally scabriculous longitudinally; c? 

 styles not produced ; ? terel)ra one-third the length of abdomen. Legs 

 slender, stramineous, with the front coxae mainly and tiie apices of the 

 intermediate, as well as part of the trochanters, flavous ; hind coxae black 

 and the posterior legs infuscate. Wings with the radix stramineous and 

 the stigma paler ; areolet pentagonal with the outer nervure wanting ; 

 transverse anal not strong but distinctly intercei)ted below the centre, at 

 least in 9- Length, 3 mm. 



This species resembles //. fulvipcs in colour, contour and the sub- 

 fusiform 9 antennae, but is rendered distinct by its much narrower basal
