PTEROMALIDAE OF N.W. EUROPE 493 



the following segments quadrate, or the sixth very slightly transverse ; clava 1 -6 to 1 -8 times 

 as long as broad, about as long as two and a half of the preceding funicular segments ; sensilla 

 rather sparse, in one row on each of the funicular segments. 



Thorax about i-6 times as long as broad. Pronotal collar distinctly less wide than the 

 mesoscutum, shorter medially than at the sides, medially from slightly more than one eighth, to 

 one seventh, as long as the mesoscutum, finely reticulate with a narrow shiny strip along its 

 hind edge, slightly to distinctly margined anteriorly. Mesoscutum 1 -8 to 1 -85 times as broad 

 as long, somewhat coarsely reticulate, more finely at the sides. Scutellum about as broad as 

 long, moderately convex, moderately finely reticulate, the frenum hardly more coarsely than 

 the rest. Propodeum (Text-fig. 389) somewhat more than half as long as the scutellum, medially 

 produced well behind the bases of the hind coxae ; median area 1-3 to 1-55 times as broad as 

 long, its panels almost uniformly reticulate and not very shiny ; median carina complete or 

 incomplete ; plicae sharp throughout, hardly sinuate in the middle, their posterior part converg- 

 ing slightly ; costula absent ; nucha occupying about one third the median length of the pro- 

 podeum, convex, rather more strongly reticulate than the panels of the median area, with the 

 areoles slightly lengthened in the transverse axis ; spiracles moderate-sized, oval, separated by 

 about one third their length from the metanotum ; callus moderately shiny, lightly reticulate, 

 rather sparsely pilose ; on the posterior part of the callus, above the supracoxal flange, there 

 are one to two hairs only. Postspiracular sclerite narrow, shiny, nearly smooth, with an 

 impressed line along its front edge. Mesepisternum moderately finely reticulate, with a nearly 

 smooth area below the base of the hind wing ; mesepimeron rather more coarsely reticulate ; 

 metapleuron finely reticulate. Legs rather short, moderately stout. Fore wing with upper 

 surface of costal cell bare, lower surface with a complete row of hairs and some additional ones 

 scattered over the distal third ; basal cell bare, open below ; basal vein bare or with 1 to 5 

 hairs ; speculum open below, on upper surface of wing extending below the marginal vein for 

 about half the length of the latter ; wing beyond the speculum moderately thickly pilose, the 

 area between the postmarginal and stigmal veins pilose ; apical margin ciliate ; marginal vein 

 1-4 to 1-7 times as long as the stigmal vein ; postmarginal vein from slightly shorter, to slightly 

 longer, than the marginal vein ; stigmal vein slightly curved, forming a somewhat acute angle 

 with the postmarginal ; stigma small, suboval. 



Gaster lanceolate or sublanceolate, usually as long as or slightly longer than the head plus 

 thorax, occasionally slightly shorter, i-8 to 2-3 times as long as broad ; basal tergite occupying 

 from one quarter, to slightly less than one third, the total length ; last tergite as long as or 

 somewhat longer than its basal breadth ; ovipositor sheaths slightly exserted ; hypopygium 

 extending about half way along the gaster. 



o*. Differs from the female as follows: 



Antennal scape testaceous, or more or less infuscate distally ; flagellum testaceous with the 

 incisures dark, or somewhat infuscate dorsally. Pale parts of the legs yellowish ; femora 

 lightly infuscate at the base only, or the fore and mid femora immaculate. Malar space slightly 

 to somewhat more than half the length of an eye ; oral fossa enlarged, its breadth 2-5 to 3 times 

 the malar space. Mandibles separated from the edges of the genae by a large semicircular 

 membranous space. Antennal scape as long as, or even slightly longer than, an eye ; combined 

 length of pedicellus and flagellum equal to breadth of head or hardly greater ; pedicellus 1 -6 to 

 1 -7 times as long as broad, about as long as the first funicular segment ; flagellum subcylindrical, 

 hardly stouter than the pedicellus ; first funicular segment 1 -6 to 1 -8 times, sixth 1 to 1 -4 times, 

 as long as broad ; clava about three times as long as broad, somewhat longer than the combined 

 length of the two preceding funicular segments ; hairs of flagellum standing out at an angle of 

 30 to 40 , their length about half the breadth of the segments or a little more. Propodeum about 

 two thirds as long as the scutellum ; median area about 1-25 times as broad as long. Fore 

 wing with marginal vein 1-5 to 1-75 times as long as the stigmal vein ; basal vein with up to 

 eight hairs. Gaster oval, shorter than but hardly narrower than the thorax, with a ventral plica.
