23 (22) Tegulae relatively short, up to twice, but rarely more than 1-5 times, as long 



as broad, their front edge distinctly separated from the pronotum ; marginal 

 vein of fore wing at least slightly longer than the stigmal vein, postmarginal 

 usually not longer than the marginal and sometimes very short or rudi- 

 mentary ; axillae separated by at most their own width ; glossa not 

 elongate, not or hardly projecting below the mandibles ; femoral groove 

 extending far up the mesepisternum (Text-fig. 17) : notauli most often 

 complete and moderately deep, occasionally superficial posteriorly ; female 

 ovipositor not recurved over the dorsum of the gaster, the latter without a 

 dorsal groove or ridge ....... CHALCIDIDAE 



Tegulae (Text-fig. 19) elongate, 2-5 to 3-5 times as long as broad, reaching or 

 nearly reaching the pronotum ; marginal vein of fore wing short, at most 

 three times as long as thick, sometimes nearly punctiform, not longer than 

 the stigmal vein, postmarginal vein very long ; axillae (Text-fig. 19) very 

 small and widely-separated, often not distinctly marked off from the 

 scutellum ; glossa more or less elongated, projecting below the mandibles ; 

 femoral groove shorter, extending barely two thirds up the mesepisternum ; 

 notauli usually absent, sometimes weakly indicated anteriorly ; female 

 ovipositor in most species recurved and often lying in a groove along the 

 dorsum of the gaster, if the ovipositor is normal then the dorsum of the 

 gaster is convex and hard, with a median longitudinal line or ridge (Text- 

 fig. 21) LEUCOSPIDIDAE 



24 (22) Inner orbits of eyes diverging at most slightly ventrad ; antennae inserted at 



least slightly above the level of the ventral edge of the eyes ; postspiracular 

 sclerite, sometimes also the metapleuron, bare ; postmarginal vein of fore 

 wing shorter than the marginal, sometimes hardly longer than the short 

 stigmal vein TORYMIDAE (part) 



- Inner orbits of eyes diverging strongly ventrad ; antennae inserted distinctly, 



often far, below the level of the ventral edge of the eyes ; postspiracular 

 sclerite and metapleuron usually more or less hairy ; postmarginal vein of 

 fore wing usually as long or longer than the marginal vein. (Chalcedectinae) 

 (p. 36) PTEROMALIDAE (part) 



25 (21) Pronotal collar (Text-fig. 22) large, subrectangular, its length from about two 



thirds that of the mesoscutum to longer than the latter ; head, and dorsum 

 of thorax excluding the propodeum, with numerous conspicuous piliferous 

 punctures (Text-fig. 23) which usually coalesce to form a deep, coarse 

 honeycomb sculpture ; genae with a sharp edge or flange ; propodeum 

 usually grooved or excavated down the middle ; body usually non-metallic, 

 rarely metallic, sometimes partly to wholly yellow or reddish ... 26 



- Not agreeing with all the above characters. If the pronotal collar is com- 



parable with the above in size and form, then either the head and thorax 



have a different type of sculpture, or else the genae are not sharp-edged . 27 



26 (25) Antennae with one anellus, seven funicular segments, and a solid or indistinctly 



segmented clava ; inner orbits of eyes diverging strongly ventrad 



PTEROMALIDAE (part) 



- Antennae with at most six funicular segments ; inner orbits of eyes diverging 



at most slightly ventrad EURYTOMIDAE (part) 



27 (25) Pronotal collar subrectangular, large, from about half as long as, to longer 



than, the mesoscutum. Mesoscutal notauli complete .... 28 



- Pronotal collar either not subrectangular, or else shorter than in the above. 



Notauli complete or incomplete ........ 35 



28 (27) Marginal vein of fore wing four to eight times as long as the stigmal vein ; 



postmarginal vein not or hardly longer than the stigmal. One or more of the
