PTEROMALIDAE OF N.W. EUROPE 



259 



Fore wing (Text-fig. 196) beyond the speculum relatively more sparsely pilose ; 

 with at least a small bare area between the postmarginal and stigmal veins, 

 and another just below the stigma. Lower face, laterad of the clypeus, 

 usually with more numerous and quite conspicuous punctures, these may 

 be less distinct in some small specimens. Male antennal scape at least three 

 times as long as broad ......... 3 



(2) Female antennal scape reaching to, or above, the level of the vertex ; funicle 



of practically uniform thickness and slightly stouter than the pedicellus ; 

 clava, except in small specimens, at least slightly shorter than the combined 

 length of the three preceding funicular segments. Male antennal scape 

 reaching slightly to far above the level of the vertex, its length fully equal 

 to or slightly greater than the transverse diameter of an eye ; combined 

 length of pedicellus and flagellum about 1-3 times the breadth of the head ; 

 first funicular segment at least slightly longer than the pedicellus, all the 

 funicular segments distinctly longer than broad ; bristles of flagellum 

 standing out at an angle of 40 to 45 ....... 4 



Female antennal scape hardly reaching level of vertex ; funicle (Text-fig. 194) 

 thickening slightly towards the clava, which is as long as the three preceding 

 funicular segments together. Male scape not reaching above level of 

 vertex, its length hardly as great as the transverse diameter of an eye ; 

 combined length of pedicellus and flagellum only slightly greater than the 

 breadth of the head ; first funicular segment (Text-fig. 193) shorter than 

 the pedicellus, funicular segments quadrate or at most slightly longer than 

 broad ; bristles of flagellum standing out at a smaller angle, sometimes 

 nearly decumbent .......... 5 



(3) Female larger (length i-6 to 2-4 mm., but usually more than 1-9 mm.) ; 



gaster 1-4 to 1-7 times as long as broad, usually slightly shorter than, 

 occasionally as long as, head plus thorax . . encyrtoides Walker (p. 261) 



Female i-6 to 1-9 mm. ; gaster 1-75 to i-g times as long as broad, slightly 

 longer than head plus thorax. Slovakia : perhaps only a form of encyrtoides 



sp. indet. 

 (3) Female gaster about 1-3 times as long as head plus thorax, and about 2-5 

 times as long as broad. Head in frontal view with vertex strongly arched ; 

 eyes separated by about 1 -45 times their length . longula Boudek (p. 263)
