PTEROMALIDAE OF N.W. EUROPE 121 



are testaceous ; fore tibiae testaceous to fuscous, mid and hind tibiae fuscous with their bases 

 and tips narrowly pale, or testaceous with a median infuscate band ; tarsi pale testaceous 

 proximally, darkening gradually to brown distally, the fore tarsi darker than the others. 

 Tegulae fuscous. Wings slightly greyish ; venation brownish testaceous. Length 23 to 

 25 mm. 



Clypeus alutaceous, its anterior margin with a smooth strip. Tentorial pits as in subglaber 

 sp.n. Genae and face wholly reticulate. Eyes separated by 1-2 to 1 -3 times their length ; 

 eye-length 2-2 to 27 times the malar space. Antenna (Text-fig. 82) with scape 28 to 3 times 

 as long as broad, not reaching above the level of the middle of the median ocellus, expanded 

 above the middle, its outer surface with vague indications of a boss ; combined length of 

 pedicellus and flagellum 17 to i-q times breadth of head ; funicle slightly stouter than the 

 pedicellus, but only when the latter is seen in profile, its first segment 1 -8 to 2 times, sixth 

 1-4 to i-6 times, as long as broad ; clava 3 to 3-5 times as long as broad, slightly longer 

 than the two preceding funicular segments together ; flagellum fairly thickly clothed with 

 hairs which stand out at 30 to 45 , the length of these hairs about equal to, the breadth of the 

 segments that bear them ; sensilla relatively sparse, arranged in one irregular row on each 

 segment, or in two rows on some of the segments. 



Scutellum (Text-fig. 86) with sculpture of about middle third engraved, with elongate areoles, 

 though not quite so elongate as in male dolosus ; elsewhere the sculpture is very slightly raised 

 above the general surface, with the areoles only moderately (some hardly) elongate. Dorsellum 

 polished, smooth or virtually so. Propodeum (except the calli) moderately shiny, with fine 

 reticulation which is only very slightly raised ; calli a little less shiny, with their sculpture 

 slightly more raised. Metapleuron bare, sculptured much like the calli. Mesepimeron with 

 sculpture like that of the main part of the propodeum. Fore wing : costal cell moderately 

 broad (8-5 to 9 times as long as broad), its front edge slightly curved outwards, its lower surface 

 with a complete, sometimes partly double, row of hairs, plus some scattered ones in the distal 

 third, its upper surface with a single row in the distal third ; basal vein pilose ; basal cell 

 closed below except at base, and with one to two irregular rows of hairs below the submarginal 

 vein ; speculum closed below. 



Closely resembles the male of dolosus (Walker), but has the antennal scape shorter and broader, 

 not reaching the vertex, flagellum with somewhat less outstanding hairs ; sculpture of scutellum 

 rather less fine and less obviously striate ; propodeum not tinged with violet or purple behind 

 the spiracles (as it often is in dolosus). 



9. Differs from the o* as follows : 



Head, and thorax dorsally, green to blue-green, the side-lobes of the mesoscutum bluish 

 discally ; axillae and scutellum somewhat duller than the rest of the thorax (tending towards 

 bronze). Antennal scape sometimes more or less testaceous proximally. Malar space longer 

 (length of eye i-8 to 2-1 malar space). Antenna with scape reaching level of vertex or (usually) 

 a little above it, slightly more than three quarters as long as an eye, and its length slightly 

 to very distinctly greater than the transverse diameter of an eye ; combined length of pedi- 

 cellus and flagellum 1-3 to 1-35 times breadth of head ; pedicellus 1-7 to i-8 times as long as 

 broad, slightly shorter than the first funicular segment ; flagellum subclavate ; funicle proxi- 

 mally distinctly a little stouter than the pedicellus, thickening very slightly distad, its first 

 segment 1 -55 to 1 -8 times as long as broad, sixth quadrate or very slightly transverse ; clava as 

 long as, or somewhat longer than, the two preceding funicular segments together ; hairs of 

 flagellum standing out only very slightly ; sensilla not very numerous, sometimes in one irregular 

 (distal) row on each segment, but usually with a partial second (proximal) row on at least the 

 proximal segments of the funicle. Scutellum flatter and broader, rather less finely sculptured. 

 Fore wing with costal cell 10 to 12 times as long as broad, sometimes slightly infuscate basally. 

 Gaster slightly longer than head plus thorax, 2-3 to 2-7 times as long as broad, about as broad 

 as the thorax ; last tergite about as long as its basal breadth ; hypopygium extending half, or a 

 little more than half, way along the gaster. 



The female is very close to that of dolosus (Walker) , which differs in having the side-lobes of the
