PTEROMALIDAE OF N.W. EUROPE 679 



proximally, to wholly, testaceous ; pedicellus and flagellum infuscate dorsally, more or less 

 testaceous beneath. Coxae, and femora except their tips, concolorous with the thorax ; 

 trochanters dark, trochantelli and rest of legs testaceous, the tibiae usually broadly infuscate 

 medially, the tips of the tarsi, the fore tarsi mainly, brownish. Tegulae more or less testaceous 

 anteriorly, fuscous posteriorly. Wings slightly tinged with grey ; venation testaceous or 

 brownish. Length 2 to 2-3 mm. 



Head only slightly broader than the mesoscutum ; in dorsal view approximately twice as 

 broad as long, with temples rounded off and only about one quarter as long as eyes ; POL 

 1-85 to 2 times OOL. Head in frontal view subtrapeziform, with genae converging towards 

 the oral fossa and nearly straight ; eyes separated by about 11 times their length ; malar 

 space slightly less than half the length of an eye. Clypeus mainly striate, its anterior margin 

 narrowly shiny and nearly truncate. Rest of head finely reticulate, the frons rather more 

 coarsely. Antennae with lower edge of toruli at about level of ventral edge of eyes ; combined 

 length of pedicellus and flagellum very slightly less than breadth of head ; pedicellus (profile) 

 about twice as long as broad, about as long as anelli plus half of the first funicular segment ; 

 flagellum proximally hardly stouter than the pedicellus but clavate distally ; anelli distinctly 

 though not very strongly tranvserse, the first and second very short, the third longer and 

 1*5 to 1-7 times as broad as long ; proximal segments of funicle subquadrate, distal segments 

 slightly transverse ; clava broader than fifth funicular segment, hardly twice as long as broad, 

 virtually as long as the three preceding funicular segments together ; sensilla sparse, in one 

 row on each segment of the funicle. 



Thorax about 1 -6 times as long as broad. Pronotal collar somewhat less wide than the meso- 

 scutum, extremely short medially, from one sixteenth to one twelfth as long as the mesoscutum, 

 but quite long at the sides, finely reticulate, its front edge with a trace of a fine margin in the 

 middle. Mesoscutum 1-4 to 1-5 times as broad as long, moderately convex, finely reticulate, a 

 little more coarsely posteriorly, and rather dull, with some small and shallow piliferous punc- 

 tures which are not easily seen amongst the reticulation. Scutellum slightly longer than broad, 

 rather weakly convex, but with its surface appearing distinctly curved in profile, very finely 

 reticulate like the axillae. Dorsellum a convex transverse strip which is separated from the 

 scutellum by a non-costate suture. Propodeum only about one third as long as the scutellum, 

 medially produced only slightly beyond the bases of the hind coxae ; median area very finely 

 reticulate, not distinctly defined laterally, the plicae being weak or obsolete in front, and sharp 

 only posteriorly, with the basal foveae small and transversely oval, the posterior foveae, at 

 sides of nucha, large and deep ; median carina weak or indistinct ; spiracles short-oval, sepa- 

 rated by about half their length from the metanotum. Postspiracular sclerite fairly broad, 

 mainly very finely, though quite strongly, reticulate. Mesepisternum and mesepimeron finely 

 reticulate, the mesepisternum with a mainly smooth triangle below the base of the hind wing ; 

 metapleuron more finely and weakly reticulate than the mesepimeron, especially dorsally. 

 Fore wing with costal cell rather narrow, its upper surface bare or virtually so, its lower surface 

 with a complete row of hairs and some additional hairs scattered over the distal third ; basal 

 cell on upper surface of wing with its distal third to half pilose ; speculum open or partly open 

 below, on upper surface of wing extending only to the base of the marginal vein ; surface 

 beyond the speculum rather densely, and nearly uniformly, pilose ; marginal vein 1-75 to 1-85 

 times as long as the stigmal vein ; postmarginal as long as, or even a little longer than, the 

 marginal. 



Gaster, including ovipositor sheaths, 1-25 to 1-4 times as long as head plus thorax, somewhat 

 compressed and narrower than the thorax ; basal tergite occupying about one fifth of the total 

 length, its hind margin entire ; last tergite 1-4 to 1-7 times as long as its basal breadth, its 

 posterior portion, behind the pygostyles, sublinear and closely applied to the ovipositor sheaths, 

 the latter very distinctly exserted, their projecting part nearly or about as long as the first 

 segment of the hind tarsus ; hypopygium extending nearly half the distance from base of 

 gaster to tips of ovipositor sheaths.
