PTEROMALIDAE OF N.W. EUROPE 397 



75 (74) Pronotal collar weakly and irregularly margined. Stigma of fore wing (Text- 



fig- 3 IQ ) subcircular, rather large, separated by less than twice its height 

 from the lower edge of the postmarginal vein. Propodeal nucha represented 

 only by a narrow, smooth or weakly aciculate transverse strip 



PSEUDOCATOLACCUS Masi (p. 694) 

 Pronotal collar sharply and regularly margined. Stigma of fore wing smaller 

 except in Synedrus, in which it is oval in shape, in that genus also the pro- 

 podeum has a reticulate nucha ........ 76 



76 (75) Spiracles of propodeum touching the hind margin of the metanotum, the 



front part of the spiracular rim partly hidden ; propodeum medially more 

 than half as long as the scutellum and produced well beyond the bases of 

 the hind coxae ; the nucha short, transversely aciculate, rather well-defined 

 in front. Funicular segments about 1 -5 times as long as broad 



VRESTOV.IA Boucek (p. 828) 

 Spiracles of propodeum at least slightly separated from the hind margin of the 

 metanotum. If the propodeum is more than half as long as the scutellum, 

 then the nucha is reticulate and not very distinctly defined in front, while 

 the funicular segments are relatively longer . . . . . . 77 



77 (76) Propodeum, medially, more than half as long as the scutellum, produced well 



beyond the bases of the hind coxae ; nucha reticulate, not very distinctly 

 defined in front. Stigma of fore wing rather large, separated by less than 

 twice its height from the lower edge of the postmarginal vein. At least the 

 proximal funicular segments twice or more than twice as long as broad 



SYNEDRUS Graham (p. 583) 

 Propodeum, medially, at most half as long as the scutellum, less strongly 

 produced backwards ; nucha represented only by a narrow, transversely- 

 lunate strip which is smooth or transversely aciculate. Stigma of fore 

 wing often smaller. Funicular segments sometimes relatively shorter . 78 



78 (77) First funicular segment shorter than, or at most as long as, the pedicellus ; 



all the funicular segments varying from slightly transverse to slightly 

 longer than broad. Left mandible with three teeth, right mandible with 

 four KALEVA Graham (p. 596) 



- First funicular segment longer than the pedicellus ; all the funicular seg- 



ments longer than broad. Both mandibles with four teeth ... 79 



79 (78) Marginal vein of fore wing twice or nearly twice as long as the stigmal vein. 



Anterior margin of clypeus very broadly truncate. Body bright green 



LONCHETRON Graham (p. 596) 

 Marginal vein 12 to 1-3 times as long as the stigmal vein. Anterior margin of 

 clypeus shallowly emarginate. Body dark green, bluish, or bronze 



CAPELLIA Delucchi (p. 475) 



80 (73) Mesepisternum wholly reticulate. Antennae with combined length of 



pedicellus and flagellum much less than breadth of head ; flagellum 

 strongly clavate, with distal segments of funicle strongly transverse. 

 Gena with a small hollow ..... KALEVA Graham (p. 596) 

 Mesepisternum usually with a mainly to entirely smooth subtriangular area 

 below the base of the hind wing ; if this area is wholly reticulate, then the 

 antennae are different in form . . . . . . . .81 



81 (80) Anterior margin of clypeus with a median tooth or tubercle, often also with an 



angular projection on either side of it (Text-figs. 468, 469) ... 82 



- Anterior margin of clypeus without a median tooth or tubercle ... 83 



82 (81) Propodeum with a rather large reticulate nucha. Genae (Text-fig. 572) 



produced somewhat ventrad of level of anterior margin of clypeus ; the 

 latter with a median tooth only. Thorax slightly flattened ; scutellum
