PTEROMALIDAE OF N.W. EUROPE 317 



about 2-5 times as broad as long, its anterior margin evenly but not strongly curved. Mandibles 

 moderate-sized, not falcate, their teeth only moderately long, the outer one longest, the others 

 decreasing slightly in length. Head with extremely fine sculpture which is hardly raised 

 above the general surface, rather shiny, slightly duller on the vertex. Antennal scape distinctly 

 shorter than an eye, not reaching the median ocellus ; combined length of pedicellus and 

 flagellum about equal to the breadth of the head ; pedicellus in profile about 1 -8 times as long 

 as broad, as long as or very slightly longer than the first funicular segment ; funicle proximally 

 slightly stouter than the pedicellus, thickening distad, its first segment 1-3 to i-6 times as 

 long as broad, second segment quadrate, the fifth slightly transverse, the fourth and fifth seg- 

 ments are also slightly asymmetric, somewhat oblique ; clava slightly more than twice as long 

 as broad, about as long as two and a half of the preceding funicular segments. 



Thorax about i-6 times as long as broad. Mesoscutum about i-6 times as broad as long, 

 with extremely fine engraved sculpture ; mid lobe fairly thickly haired ; notauli nearly straight, 

 deep. Scutellum about as long as the mesoscutum, distinctly longer than broad, its sculpture, 

 except that of the frenum, rather finer than that of the mesoscutum, with three to four pairs of 

 bristles ; the scutello-axillar sutures converge moderately strongly forwards in straight lines 

 to meet the mesoscutum somewhat mesad of the hind ends of the notauli, the base of the 

 scutellum being about one sixth the breadth of the mesoscutum. Dorsellum slightly more 

 than one third as long as the frenum, weakly alutaceous, shiny. Propodeum rather deeply 

 emarginate posteriorly, hence rather short medially, rather more than one quarter as long as the 

 scutellum, with fine alutaceous sculpture which is hardly raised above the surface, moderately 

 shiny ; median carina fine though complete ; plicae absent ; spiracles slightly oval, transversely 

 so, nearly touching the metanotum ; callus with three to four bristles. Metapleuron with fine 

 alutaceous, hardly raised, sculpture ; mesepisternum with similar sculpture, but slightly 

 smoother below the bases of the wings ; mesepimeron marked off by a distinct grooved line, 

 nearly four times as long as broad ; mesosternum with sculpture similar to that of the mes- 

 episternum but slightly smoother medially, its mesolcus sharply impressed ; postspiracular 

 sclerite with reticulate sculpture which is slightly coarser and more raised than that of the 

 mesopleuron. Legs somewhat short and stout ; hind coxae about twice as long as broad, 

 sculptured much as the metapleuron, their dorsal surface with two to three hairs ; spur of mid 

 tibia more than three quarters the length of the first tarsal segment. Fore wing about twice 

 as long as broad ; costal cell broad (length : breadth nearly 8 : 1), its lower surface fairly 

 thickly hairy, its upper surface with one, sometimes partly double, row of hairs in the distal 

 half of the cell ; basal cell hairy over its distal third ; speculum open or partly closed below, 

 moderate-sized, on the upper surface of the wing extending as a bare strip under the proximal 

 half of the marginal vein ; wing beyond the speculum rather thickly haired ; marginal vein 

 1 5 to i-6 times as long as the postmarginal vein and 21 to 2-3 times the length of the stigmal 

 vein, the latter straight with a moderate-sized stigma which is subrectangular and longer than 

 high (Text-fig. 262). 



Gastral petiole strongly transverse. Gaster ovate, excluding the ovipositor sheaths nearly 

 or about as long as the thorax, almost as broad as the thorax, 1 -5 to 1 -75 times as long as broad ; 

 basal tergite basally convex with a longitudinal impression on each side, occupying about one 

 third of the total length of the gaster ; last tergite transverse ; ovipositor sheaths slightly 

 exserted ; ventrally the gaster is convex, the tip of the hypopygium situated about in the 

 middle. 



o". Unknown. 



This species is very near hemigaster sp. n. and crassus Walker, but differs from both 

 in being on the average larger, with more numerous, and very conspicuous, piliferous 

 punctures on the mesoscutum, with the antennal scape at least partly testaceous, 

 the head and thorax usually more brightly metallic. From hemigaster it also differs 

 in having 3-4 (instead of 2) pairs of bristles on the scutellum, the propodeum rather
