PTEROMALIDAE OF N.W. EUROPE 325 



long ; temples extremely short, receding strongly ; POL 1-5 to i-6 OOL, ocelli in a triangle 

 whose base is about 2-25 times its height. Eyes rather small, separated by about 1 -5 times their 

 length. Head in front view suboval, the vertex strongly arched, the cheeks converging moder- 

 ately strongly and in straight lines towards the mouth. Malar space slightly less than half the 

 length of an eye. Breadth of oral fossa about 2-5 times the malar space. Clypeus about 2-5 

 times as broad as long, its front margin evenly and quite strongly curved. Mandibles moderate- 

 sized, not falcate, their teeth only moderately long, the lower (outer) one longest, the other 

 becoming progressively a little shorter. Vertex and upper part of frons rather dull, with 

 extremely fine, engraved sculpture ; lower frons, face, clypeus and cheeks shiny, with delicate, 

 only weakly engraved sculpture. Antennal scape almost as long as an eye, but not reaching 

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

 breadth of the head ; pedicellus (in profile) about 1-7 times as long as broad, from as long as to 

 distinctly longer than the first funicular segment ; funicle proximally not or hardly stouter than 

 the pedicellus, becoming thicker distad, its first segment as long as or slightly longer than the 

 second, varying from subquadrate to 1-7 times as long as broad, the second segment quadrate 

 or very slightly longer than broad, the fifth, or fourth and fifth, slightly transverse ; clava hardly 

 broader than the fifth funicular segment, nearly twice as long as broad, slightly shorter than the 

 combined length of the three preceding funicular segments ; flagellum with rather outstanding, 

 bristly hairs ; sensilla not numerous. 



Thorax nearly 1-5 times as long as broad. Mesoscutum about 1-7 times as broad as long, 

 somewhat shiny, with very fine delicately engraved sculpture ; its mid lobe with numerous 

 bristles which arise from tiny warts, the bristles are especially numerous anteriorly ; notauli 

 deep, nearly straight. Axillae and scutellum sculptured much like the mesoscutum. Scutellum 

 very slightly longer than the mesoscutum, slightly longer than broad, strongly convex, with 

 three to four pairs of bristles arranged in two longitudinal rows ; frenum marked off by a very 

 fine line ; the scutello-axillar sutures meet the hind margin of the mesoscutum only a little 

 mesad of the hind ends of the notauli. Dorsellum very short, only about one third the length 

 of the frenum, polished and without sculpture. Propodeum short, medially hardly one fifth 

 the length of the scutellum, smooth and polished ; median carina and plicae absent ; spiracles 

 subcircular, separated by about one third their diameter from the hind edge of the metanotum ; 

 callus thickly hairy, the hairs extending almost to the edge of the metapleuron. Metapleuron 

 (Text-fig. 205) with a trace of weak alutaceous sculpture ; mesopleuron and mesosternum wholly 

 polished and smooth ; mesepimeron not marked off from the mesepisternum ; mesolcus nearly 

 obsolete. Legs with hind coxae somewhat more than twice as long as broad, shiny, with very 

 weak alutaceous sculpture, hairy along the whole length of their dorsal surface. Fore wing 

 slightly more than twice as long as broad ; costal cell broad (length : breadth about 8 or 9 : 1), 

 its lower surface with rather numerous hairs, its upper surface bare except for a row of several 

 hairs in the distal half ; basal cell hairy over about its distal third ; speculum closed below by 

 a line, sometimes even by two lines, of hairs on the cubital vein, on the upper surface of the 

 wing moderately large, on the lower surface more or less effaced by scattered hairs ; wing 

 beyond the speculum rather thickly haired ; marginal vein 1-3 to 1-4 times as long as the 

 postmarginal vein and 1-7 to i-q times as long as the stigmal vein, the latter curved, the stigma 

 moderate-sized and obliquely oval, with a distinct uncus. 



Gaster lanceolate, slightly longer than head plus thorax, somewhat narrower than the thorax, 

 acute apically, slightly compressed, sunken dorsally beyond the basal tergite, the latter usually 

 remains convex after drying and its basal fovea is absent or hardly indicated ; ovipositor 

 sheaths slightly exserted, to at most the length of the last tergite ; hypopygium extending only 

 about one third the length of the gaster. 



<$. Differs from the female as follows : 



Antennal scape somewhat shorter than an eye, hardly more than three times as long as broad ; 

 pedicellus in profile, only about 1-5 times as long as broad ; combined length of pedicellus and 

 flagellum about 1-2 times the breadth of the head ; funicle hardly stouter distally than proxi- 

 mally ; first funicular segment varying from almost quadrate to 1-7 times as long as broad, as
