PTEROMALIDAE OF N.W. EUROPE 557 



concolorous with the thorax ; trochanters partly dark ; rest of legs testaceous with tips of 

 tarsi fuscous, the fore tarsi mainly brownish ; tibiae in one specimen very slightly darkened 

 medially. Tegulae testaceous anteriorly, dark posteriorly. Wings hyaline ; venation yellowish 

 or testaceous. Length 2-6 to 3 mm. 



Head about 1-2 times as broad as mesoscutum ; in dorsal view (Text-fig. 414) about 2-25 

 times as broad as long ; temples slightly more than one third as long as eyes, rounded off ; 

 ocelli unusually small, the posterior ones separated by 3 to 3-5 times their major diameter 

 from the eyes, POL hardly greater than (at most 1 -i) OOL. Head in front view subtrapeziform 

 with the genae only slightly curved ; eyes separated by 1 -5 times their length or slightly more. 

 Malar space nearly or quite two thirds as long as an eye. Breadth of oral fossa 1 -g to 2 times 

 the malar space. Clypeus radiately strigose, its anterior margin shallowly emarginate and 

 hardly impressed in the middle. Head finely reticulate, very finely on the genae ; malar sulcus 

 absent, its position partly indicated by a band of excessively fine reticulation. Antennae 

 inserted low on the head, the lower edge of the toruli at or hardly above the level of the ventral 

 edge of the eyes ; scape only slightly shorter than an eye, reaching about level with the middle 

 of the median ocellus ; combined length of pedicellus and flagellum slightly less than breadth 

 of head, in one female virtually equal to it ; pedicellus in profile 1 -7 to 1 -8 times as long as 

 broad, at least slightly longer than the first funicular segment ; flagellum slightly clavate ; 

 funicle proximally slightly stouter than the pedicellus, its first segment quadrate to 1-25 times 

 as long as broad, the following segments quadrate or hardly longer than broad, the fifth and 

 sixth sometimes very slightly transverse ; clava about 2-5 times as long as broad, its length 

 about equal to two and a half of the preceding funicular segments ; sensilla not very numerous, 

 in one row on each funicular segment. 



Thorax nearly 1 -5 times as long as broad. Pronotal collar much less wide than the meso- 

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

 seventh, as long as the mesoscutum, moderately finely reticulate, more or less distinctly margined 

 over the middle third, or almost throughout. Mesoscutum i-6 to 1-7 times as broad as long, 

 finely reticulate, slightly less finely on the disc posteriorly. Scutellum hardly longer than 

 broad, very finely reticulate, the frenum more coarsely. Axillae very finely reticulate. Pro- 

 podeum (Text-fig. 371) medially slightly more than one third as long as the scutellum and only 

 slightly produced beyond the bases of the hind coxae ; median area 1 -g to 2-2 times as broad as 

 long, its panels moderately shiny and very finely obliquely strigose-reticulate ; median carina 

 complete, usually strong ; costula absent ; plicae distinct throughout, curved and hardly 

 sinuate, their posterior part, on sides of nucha, converging quite strongly ; nucha very short, 

 transversely aciculate ; spiracles long-oval, separated by about one third their length from the 

 metanotum ; spiracular sulci distinctly impressed, punctate or with a few transverse costulae ; 

 callus alutaceous, shiny, rather sparsely pilose. Postspiracular sclerite narrow, shiny, weakly 

 sculptured, with an impressed line along its front margin. Mesepisternum moderately finely reticu- 

 late, with a mainly smooth area below the base of the hind wing ; mesepimeron usually rather less 

 finely reticulate ; metapleuron finely, and sometimes weakly, reticulate. Legs not very slender. 

 Fore wing with upper surface of costal cell bare, lower surface with a complete row of hairs 

 and a few additional ones in the distal third ; basal cell bare, open below ; basal vein bare or 

 with a few 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 sometimes bare at the base ; apical 

 margin of wing ciliate ; marginal vein 1 -5 to 1 -6 times as long as the stigmal vein ; postmarginal 

 vein slightly shorter than, or at most as long as, the marginal vein ; stigmal vein straight or 

 slightly curved, stigma small and suboval. 



Gaster lanceolate, 1-15 to 1-4 times as long as head plus thorax, only slightly compressed and 

 usually not or only slightly narrower than the thorax, 2-7 to 3-5 times as long as broad ; basal 

 tergite occupying about one fifth the total length ; last tergite slightly to considerably, up to 

 1-7 times, longer than its basal breadth ; ovipositor sheaths slightly exserted ; hypopygium 

 extending about half way along the gaster.
