PTEROMALIDAE OF N.W. EUROPE 541 



head similar but tending most often towards dark bluish or olive ; basal tergite of gaster more 

 or less tinged with bronze, brassy, or coppery. Antennae fuscous ; scape more or less test- 

 aceous basally. Coxae, and femora except their tips, concolorous with the thorax ; trochanters 

 mainly dark ; tibiae mainly fuscous to black, their bases and tips testaceous ; tarsi testaceous 

 proximally, brown distally, the fore tarsi usually wholly brown. Tegulae black with a metallic 

 tinge. Wings slightly greyish ; venation testaceous to fuscous. Length 2-6 to 3-2 mm. 



Head only slightly broader than the mesoscutum ; in dorsal view shaped much as in albi- 

 pennis, but with the temples hardly one third as long as the eyes. Eyes separated by about 1 -3 

 times their length. Malar space hardly half as long as an eye. Sculpture of head, and structure 

 of clypeus, much as in albipennis. Antennae inserted distinctly above the level of the ventral 

 edge of the eyes ; scape about three quarters as long as an eye, reaching only to the level of 

 the lower edge of the median ocellus ; combined length of pedicellus and flagellum only very 

 slightly less than breadth of head ; pedicellus in profile 1 -0 to 1-7 times as long as broad, as 

 long as or slightly longer than the first funicular segment ; funicle slightly stouter than the 

 pedicellus, cylindrical or weakly clavate ; first funicular segment quadrate or slightly, up to 

 1 -3 times, longer than broad, distal segments quadrate, or the sixth slightly transverse ; clava 

 hardly twice as long as broad, slightly longer than the combined length of the two preceding 

 funicular segments ; sensilla fairly numerous, usually in two irregular rows on at least the proxi- 

 mal segments of the funicle, sometimes 111 only one irregular row. 



Thorax, excluding propodeum, similar to that of albipennis. Propodeum (Text-fig. 380) 

 about one third as long as the scutellum ; median area 2-25 to 2-5 times as broad as long, its 

 panels shiny with some longitudinal costulae or coarse wrinkles, but with little fine reticulation ; 

 costula fairly distinct, strongly angulate in the middle, where it nearly touches the base of 

 the propodeum ; median carina usually absent, occasionally extending as far as the nucha ; 

 other details much as in albipennis. Fore wing with lower surface of costal cell with one com- 

 plete row of hairs, and some other hairs scattered over the distal third of the cell ; basal vein 

 usually with some (up to six) hairs ; speculum open below, extending below the marginal vein 

 for at most half the length of the latter ; wing beyond the speculum moderately thickly pilose, 

 the area between the postmarginal and stigmal veins mainly pilose ; apical margin of wing 

 ciliate ; marginal vein 1-35 to 1 -4 times as long as the stigmal vein ; postmarginal vein at least 

 very slightly shorter than the marginal. 



Gaster lanceolate, as long as or longer than, up to 1 -3 times, head plus thorax, 2-5 to 2-8 times 

 as long as broad, somewhat compressed though usually only a little narrower than the thorax ; 

 basal tergite occupying hardly one quarter of the total length, its hind margin usually distinctly 

 emarginate medially, rarely entire ; last tergite as long as, or slightly longer than, its basal 

 breadth ; ovipositor sheaths distinctly exserted, often to a length equal to about half that of the 

 last tergite ; hypopygium extending about half way along the gaster. 



o*. Differs from the female as follows : 



Antennae with combined length of pedicellus and flagellum i-i to 1-2 times the breadth of 

 the head ; pedicellus in profile 1 5 to 1 -6 times as long as broad, slightly shorter than or as long 

 as the first funicular segment ; flagellum moderately stout, slightly stouter than the pedicellus 

 when the latter is seen in dorsal view, cylindrical ; first funicular segment 1 -2 to 1 -5 times as 

 long as broad, sixth usually quadrate or very slightly longer than broad, very slightly trans- 

 verse in dwarfs ; clava 2-7 to 2-8 times as long as broad, slightly longer than the combined 

 length of the two preceding funicular segments ; most of the hairs clothing the flagellum stand 

 out at rather less than 45 , the length of the hairs is about equal to half the breadth of the 

 segments that bear them. Gaster oval, slightly shorter and narrower than the thorax, with a 

 ventral plica. 



The female of myopitae sp. n. most closely resembles that of cardui (Erdos), but 

 differs in having the propodeum slightly longer, its median area less strongly 

 transverse with the costula distinctly angulate in the middle and less strong ;
