PTEROMALIDAE OF N.W. EUROPE 313 



quadrate, fourth and fifth slightly transverse ; clava slightly more than twice as long as broad, 

 its length about equal to two and a half of the preceding funicular segments ; flagellum with 

 somewhat outstanding hairs, sensilla sparse. 



Thorax about 1-5 times as long as broad. Mesoscutum about i-8 times as broad as long, 

 shiny, with fine delicate, for the most part engraved, sculpture ; mid lobe more sparsely haired 

 than in laticornis (cf. text-fig. 253) ; notauli deep. Scutellum somewhat longer than meso- 

 scutum, distinctly longer than broad, strongly convex in its transverse axis, with sculpture like 

 that of the mesoscutum, with three to four pairs of bristles ; frenum marked off by a fine, weak 

 line ; scutello-axillar sutures not converging strongly, meeting the mesoscutum slightly mesad 

 of the notauli, the base of the scutellum being about one fifth the breadth of the mesoscutum. 

 Dorsellum hardly half as long as the frenum, nearly smooth. Propodeum rather broadly and 

 moderately deeply emarginate medially, where its length is hardly more than one fifth that of the 

 scutellum ; surface shiny and virtually smooth ; median carina absent or, in one specimen, 

 represented by a mere trace ; plicae absent ; spiracles subcircular, npt quite touching the 

 metanotum ; callus with four to six bristles. Metapleuron shiny, with fine delicate alutaceous, 

 hardly raised, sculpture. Mesepimeron distinctly marked off, nearly three times as long as 

 broad, with some very weak alutaceous sculpture ; mesepisternum smooth. Mesosternum 

 medially smooth with mesolcus distinctly impressed, laterally with rather fine, hardly raised 

 sculpture. Legs somewhat short though not stout ; hind coxae about twice as long as broad, 

 shiny, with rather fine, hardly raised sculpture, dorsally bare or with only one or two hairs ; 

 spur of mid tibia about three quarters the length of the first tarsal segment. Fore wing slightly 

 more than twice as long as broad ; costal cell about 8-5 times as long as broad, its lower surface 

 with a complete row of hairs, also some additional ones scattered over the distal half, its upper 

 surface with a row of hairs in the distal third ; basal vein pilose, basal cell bare except for a few 

 hairs near the basal vein ; speculum open below, on the upperside of the wing extending below 

 the marginal vein for about half the length of the latter ; the area between the postmarginal 

 and stigmal veins is partly bare on the upper surface of the wing ; disc moderately thickly 

 haired ; margined vein about twice as long as the postmarginal, and 2-2 to 2-5 times as long 

 as the stigmal vein, the latter hardly curved ; the stigma moderate-sized, subrectangular, 

 longer than high, its uncus moderately long. 



Petiole of gaster strongly transverse. Gaster, not counting the ovipositor sheaths, as long 

 as or very slightly longer than the head plus thorax, narrower than the thorax, pointed apically, 

 2-3 to 3 times as long as broad ; base of first tergite with a curved longitudinal fovea on each 

 side, between these usually convex ; disc of gaster sunken ; last tergite slightly compressed, 

 projecting upwards ; ovipositor sheaths slightly ascending, in profile exserted to a length 

 varying from slightly more than one third to a little more than half the hind tibia ; ventrally 

 the gaster is convex, with the hypopygium extending rather less than half way along.

Biology. Unknown. 



This species is very close to vagans Westwood, the female of which differs as 

 follows : antennal scape black, pedicellus and flagellum fuscous ; mesoscutum more 

 coppery bronze ; tibiae more or less infuscate ; clypeus (Text-fig. 260) having its 

 anterior margin less strongly curved, virtually truncate medially ; propodeum a little
