Melobons] BRITISH ICHNEUMONS. 173 



These meagre details by no means represent the abundance of this 

 species in Britain. It is to be frequently met with throughout the summer 

 from the 5th May to the; ist October on umbelUferous and other (lowers, 

 such as Ciciita virosa, Hcraclciim sphondvUum, Chacrophylhim sylvcstrc and 

 Staticc limoniutii, as well as bracken, reeds and rushes, whence it is most 

 frequently swept in marshy situations, though by means confnied to them, 

 for the long grass along the side of a dusty high road will often produce 

 this insect, and it sometimes occurs at dusk. I have examples from 

 Tostock and Finborough Park (Tuck), Timworth in Suffolk (Nurse) ; 

 Guildford (Butler), Woking (Morice), Shere (Capron), Greenings and 

 Copthorne (Saunders) and Grayshott (Elliott) in Surrey; Felden (I'iftard); 

 Chatham (Garde) and Blackheath (Beaumont) in Kent; Hunstanton 

 (Brunetti) and King's Lynn (Atmore) ; l^otusfleming, Nunton, Bishops 

 Teignton and (kwilon in Wales (Marshall). Lake Nemocka in Mayo 

 (Halbert), Waterville in Ireland (Yerbury) ; Armagh and Co. Down 

 (Johnson). Kings Cross in Arran and Kenmare (Dalglish), Aberlady 

 (Verbury), Banchory, Park, Braemar, Fincean and Clunie in Scotland 

 (Elliott). My eighty specimens are from all parts of Suffolk, where it 

 most abounds in the N.W. fens and coast salt-marshes;* Louisburgh in 

 Co. Mayo; Shanklin in I.W.; Matley Bog where I have swept the pupa 

 in August, Hinchelsea and Lyndhurst in New Forest; on the Rye sand- 

 hills in Sussex; Salisbury; Gosfield in Essex and Holme, Wintcrton, 

 Wroxham and Hickling Broads in Norfolk. The cocoon is pure white 

 with an irregular band of large black spots on either side of its centre. 



PECTENELLA, n.n. 



Head stout, distinctly transverse and but little constricted posteriorly ; 

 clypeus very obsoletely discreted, with no apical tooth and but inconspic- 

 uous lateral foveae ; mandibles not weak, with teeth of equal length ; face 

 transverse and subparallel-sided ; eyes glabrous and not internally emar- 

 ginate. Thorax not convex; metathorax basally somewhat smooth and 

 not apically produced ; metanotal carinae strong, with coslulae subentire; 

 areola not longer than broad, basally constricted, apically truncate and 

 entire ; petiolar area rugose, not distinctly excavate and extending but 

 little beyond metathoracic centre ; spiracles circular. Abdomen stout 

 and distinctly nitidulous ; basal segment stout and not elongate ; petiole 

 with lateral sulci distinct, postpetiole broader and discally convex; second 

 segment not or hardly longer than broad with subcentral spiracles ; 

 seventh segment not emarginate ; terebra exserted, straight and nt)t 

 slender. Legs distinctly a little stout, with onychii and onyches large ; 

 claws strongly and elongately pectinate. Wings not broad, with strong 

 nervures; areolet entire and petiolate or wanting; radial nervure hardly 

 angled at the areolar, its apical abscissa nearly double length of the basal ; 

 lower basal nervure not oblique; nervellus oblitjue, slightly curved but 

 not at all geniculate. 



This genus is allied to Gonolypa in its short basal segment, with dis- 

 tinct petiolar sulci and quadrate postpetiole which, however, is distinctly 

 broader, with the alar areolet entire, the flagellum not slender, the dis- 

 coidal cell apically acute and the nervellus not geniculate ; the stout and 

 elongate pectination of the claws is remarkable. 



* I was so fortunate as to sweep u pair of tfiis species in copula from reeds in tlie salt marshes 

 near Easton Broad on i6th Septenibtr, 1914, at 11.45 'aaw.
